It is relatively insensitive to the Khamsinwinds prevalent during spring in the Middle East and may be dispersed by them. [1] One which shows promise as a biocontrol agent is Aphelinus asychis. It also affects citrus, cotton and hibiscus. Alejandra Bravo, ... Mario Soberón, in The Comprehensive Sourcebook of Bacterial Protein Toxins (Fourth Edition), 2015. According to Nelson (2001), pests known to attack noni in Hawaii include aphids (Aphis gossypii), ants, scales (the green scale), mites (eriophyid mites), whiteflies (fringe guava whitefly), and slugs. A propeptide sequence was added at the C-terminal end of Vip2A toxin. However, populations do not usually reach treatable levels until later in the growing season, following insecticide applications for other pests (Johnson et al., 1996). As melon aphid occasionally overwinters in greenhouses, and may be introduced into the field with transplants in the spring, it has potential to be damaging almost anywhere. It is important to use appropriate rootstocks that ensure a certain tolerance or resistance of the variety/rootstock combination. Journal of Asia Pacific Entomology 5, 185 – 191. It thrives outdoors in southern Europe but survives only under glass in northern Europe. The juvenile forms are almost always yellowish in color. The most dangerous are Aphis gossypii Glover and Toxoptera citricidus Kirk. The vertical and temporal distribution of an aphid, Aphis gossypii Glover, and the coccinellid populations on six chilli varieties were studied. [1] In the former Soviet Union it is found up to 54°N. In the southeastern United States, frequent rainfall in the fall limits the accumulation of honeydew except in dry years. Aphis gossypii is recorded from American Samoa, Australia, Cook Islands, Fiji, French Polynesia, Guam, Kiribati, Marshall Islands, Federated States of Micronesia, New Caledonia, New Zealand, Niue, Northern Mariana Islands, Papua New Guinea, Samoa, Solomon Islands, Tokelau, Tonga, Tuvalu, Vanuatu, and Wallios & Futuna. This sap-sucking insect affects plants via direct feeding and indirectly via plant viral disease transmission (more than 50 plant pathogenic viruses known). Because melon aphid sometimes overwinters in greenhouses, and may be introduced into the field with transplants in the spring, it has potential to be damaging almost anywhere.

USSR), Austria, Azores, Belgium, Britain, Bulgaria, Czechoslovakia, Denmark, Finland, France, Germany, Greece, Hungary, Italy, Malta, Netherlands, Norway, Poland, Portugal, Romania, Sardinia, Sicily, Spain, Sweden, Switzerland, Yugoslavia, ASIA (excl. A. gossypii has a worldwide distribution, although in arctic regions it is mostly confined to glasshouses. Resistance to fruit fly was controlled by a single dominant gene Fwr.39 Chambliss and Cuthberg5 found that resistance to Diabrotica balteata Lec. The average number of beetles on resistant and susceptible plants varied between 0 and 2.75. Aphids are distributed worldwide, but are most common in temperate zones. The two aphids can transmit the Tristeza virus, which is a major concern in countries where it is not yet present and where trees are grafted on susceptible rootstocks such as sour orange. It is particularly abundant in the tropics. [5], "Influence of abiotic factors on some biological and ecological characteristics of the aphid parasitoid, https://en.wikipedia.org/w/index.php?title=Aphis_gossypii&oldid=997517464, Creative Commons Attribution-ShareAlike License, This page was last edited on 31 December 2020, at 22:27. was controlled by a single recessive gene. Aphidinae: Aphidini. and D. undecimpunctata howardi Barber) were developed as a source of breeding.6 Dwarf habit, entire leaf, fruit shape and seed size are the attributes associated with resistance. TIBOR FEHÉR, in Genetic Improvement of Vegetable Crops, 1993. The study had revealed that distribution of M . It is a widely distributed pest of a variety of agricultural crops in the families Cucurbitaceae, Rutaceae and Malvaceae. It is proposed that Vip1A binds to a 50-kDa protein located in the cell surface of the aphid midgut and induces the translocation of Vip2A across the membrane. Information is given on the geographical distribution in EUROPE (excl. Only resistance against fruit fly (Decus cucurbitae Coll. The aphids are a vector of crinkle, mosaic, rosette, CTV and other virus diseases. There is no report of PRSV-P or -W seed transmission. In continuing your browsing of this site, you accept the use of cookies to offer you suitable content and services and realize visits statistics. Introduction. The control of aphids is not an easy task, as they have multiple hosts besides citrus. The cylindrical black siphunculi are wide at the base and one fifth of the body length. The cotton aphid, Aphis gossypii (Hemiptera: Aphididae), is a serious pest of Malváceae in the northeastern Brasil. According to Janick and Paul (2008) the most severe damage in Hawaii is associated with whiteflies, whereas in Micronesia the most problematic species is the leaf miner. It is a true bug and sucks sap from plants. Resistance to red pumpkin beetle (Af) was dominant to susceptibility.102, M. El-Otmani, ... L. Zacarías, in Postharvest Biology and Technology of Tropical and Subtropical Fruits: Açai to Citrus, 2011. Aphis gossypii Glover (Hemiptera: Aphididae) is a destructive pest of numerous crops worldwide. Aphis gossypii Glover is a polyphagous aphid pest with a worldwide dis-tribution. A. gossypii is extremely polyphagous and very damaging to many economically important crops, including cotton, aubergine, citrus, coffee, melon, okra, peppers, potato, squash and sesame. In the United States, it is a regular a pest in the southeast and southwest, but is occasionally damaging everywhere. It is a widely distributed pest of a variety of agricultural crops in the families Cucurbitaceae, Rutaceae and Malvaceae. We examined the effect of fertilization on population growth and within-plant distribution of melon or cotton aphid, Aphis gossypii Glover, on potted chrysanthemum, Dendranthema grandiflora (Tzvelev). United States: southeastern and southwestern United States. S.P. In Insects of Hawaii. Melon aphid occurs in tropical and temperate regions throughout the world except northernmost areas. Wraight, ... M. Faria, in Microbial Control of Insect and Mite Pests, 2017. (2002) Vertical and temporal distribution of Aphis gossypii Glover and coccinellid populations on different chilli (Capsicum annuum) varieties. Vector of crinkle, mosaic, rosette and other virus diseases. [4], The adults and nymphs of the cotton aphid feed on the underside of leaves or on the growing tips of shoots, sucking juices from the plant. They often have a dark head, thorax and wing pads and the distal portion of the abdomen is usually dark green. ... Cotton aphids (Aphis gossypii) often infect sugarcane, papaya and peanuts with viruses. (Hemipt. However, the expression of these toxins severely affected the plant development, killing the plant [41]. They cause damage by sucking sap, thus weakening the plants, and by excreting a sticky honeydew that grows into a sootylike mold on leaves that makes plants unable to carry out photosynthetic activities. The body appears dull because it is dusted with wax secretions. Life Cycle: Aphis gossypiiis viviparousthroughout the year. It is common in North and South America, Central Asia, Africa, Australia, Brazil, East Indies, Mexico and Hawaii and in most of Europe. ), cucumber beetle (Diabrotica balteata Lec. ), and the genetic background of red pumpkin beetle (Aulacophora foveicollis Lucas) are known. Melon aphid occurs in tropical and temperate regions throughout the world except northernmost areas. were shown efficient virus sources in tropical and sub-tropical regions. Volume 5. In the United States, it is regularly a pest in the southeast and southwest, but is occasionally damaging everywhere. [5], Resistance to carbamates and organophosphates has been traced to two variant acetylcholinesterase genes in A. gossypii, MACEA and MACEB. Aphis gossypii Glover. The life span of a parthenogenic female is about twenty days in which time it can produce up to 85 nymphs. Hide Fungi Hide Ascomycete Fungi Hide Basidiomycete Fungi Hide Fungoids Distribution. In general, insect damage may be more severe in locations that are dry or have low rainfall. Plant-derived cucurbitacin B (CucB) and epigallocatechin gallate (EGCG) … Because melon aphid sometimes overwinters in greenhouses, and may be introduced into the field with transplants in the spring, it has potential to be damaging almost anywhere. Order Homoptera—Aphids, Leaf- and Planthoppers, Psyllids and Whiteflies, Microbial Control of Insect and Mite Pests of Cotton, Microbial Control of Insect and Mite Pests, Citrus spp. Insecticide sprays targeting cotton aphid occur in most regions, especially in arid regions to preserve lint quality and improve milling quality. Economic damage due to A. gossypii is by direct feeding, the excretion of honeydew and virus transmission. We use cookies to help provide and enhance our service and tailor content and ads. Long-distance spread may occur through the movement of infected material (seedlings, fruits). [4], In the southern half of the US, as far north as Arkansas, sexual reproduction of the cotton aphid is not important. Indeed, aphids were shown to be able to acquire and transmit efficiently PRSV-W from commercial infected melon fruits. In Canada, it is widespread in the eastern portion of the country, extending at least as far west as Manitoba; frequent injury is limited to southern Ontario and Quebec. The following relationships have been collated from the published literature (see 'References'). 464 pages. [2], The cotton aphid has a very wide host range with at least 60 host plants being known in Florida and perhaps 700 worldwide. However, as with thrips and whiteflies, greatest damage from these pests may be caused by transmission of plant viruses. A-GOSSYP PRSV is transmitted in a non-persistent manner by more than 24 aphid species among which Aphis gossypii, Myzus persicae and A. craccivora are the most efficient. There is often a great deal of leaf curling and distortion which hinders efficient photosynthesis. Attitude and biological cycle – The objective of this research was to test the stability of population pattern of Aphis gossypii in time and space, through the parameters of the law of Taylor, Iwao and Nachman. The most important aphid-transmitted virus is sweetpotato feathery mottle virus. In plants which produce the phytoestrogen coumestrol, such as alfalfa, damage by aphids is … Common name(s) Cotton aphid, melon aphid. Aphis cucurbiti Buct. Apterae very variable in colour, large specimens dark green, almost black, but adults produced in crowded colonies at high temperature may be less than 1 mm long and very pale yellow to almost white. Its origin is in Europe. The zymogenized form of Vip2 interfered with its enzymatic function. It was proposed that it could block the active site or the NAD-binding site. [1] In Russia various wild plants are hosts to the overwintering eggs. USSR), Afghanistan, Bonin Islands, Burma, Ceylon, China, Cyprus, Gaza, Strip, Hong Kong, … Here, both males and sexual females are produced, mating takes place and the females lay eggs which overwinter, ready to repeat the life cycle the following year. As phloem feeders, aphids produce large amounts of honeydew. management strategy. In terms of pest management implications, we also investigated the effect of fertilization on the number of insecticide The cotton aphids (Aphis gossypii), which are about 1–1.5 mm long, constitute the major pest of okra in Southern Africa. Initial infestations of cotton aphid, Aphis gossypii Glover, occur between the seedling and early reproductive stages of cotton (Slosser et al., 1989). Distribution. In general, cotton aphid populations are maintained below treatable levels by the actions of natural enemies unless sprays targeting other pests have been made that disrupt the natural enemy complex (Weathersbee and Hardee, 1994). Population growth rates and within-plant distributions of Aphis gossypii Glover and Myzus persicae (Sulzer) were studied on potted chrysanthemums, Dendranthema Grandiflora Tzvelev. The population dynamics, development of gonads, takeoff and flight behaviour of Aphis gossypii Glover were investigated in order to test whether there was variation of migratory ability in the spring population. Variable watermelon populations resistant to cucumber beetle (D. balteata Lec. It is cosmopolitan in habitat. (2004) showed that leaf nitrogen is higher in young and physiologically mature leaves than older, basal leaves. Introduction to Aphis gossypii: scientific and common names, protected status (red lists, regulations), biological status in France, historical and contemporary. The legs are yellow, as are the antennae which are three quarters of the length of the body. 76-77. Aphididae) (Cotton Aphis, Melon Aphis). Classification. Aphis gossypii does not have a sexual phase in the tropics, nor in most of Europe. sexmaculatus positively correlated with its prey distribution. [1] The nymphs vary in colour, being shades of green, tan and gray. In the United States, it is a regular a pest in the southeast and southwest, but is occasionally damaging everywhere. A. Carrillo-López, E.M. Yahia, in Postharvest Biology and Technology of Tropical and Subtropical Fruits: Mangosteen to White Sapote, 2011. The total number of apterous aphid per plant stratum was significantly different among plant strata of a particular variety (treatment) as well as among the treatments. However, the accumulation of honeydew in arid regions such as the southwestern United States can result in sticky cotton. Melon aphid is widely distributed, and is known from tropical and temperate regions throughout the world except northern Canada and northern Asia. Abstract. Host Plants: polyphagous, especially cotton and Cucurbits. The apices of the femora, tibia and tarsi are black. In addition, aphids transmit the yellow vein mosaic virus in okra.. John L. Capinera, in Handbook of Vegetable Pests, 2001, Melon aphid is widely distributed, and is known from tropical and temperate regions throughout the world except northern Canada and northern Asia. Pesticides such as Abamectin and Acetamiprid are applied on trees to control the pest. [1], It is not known where this species originated, but it is now found in tropical and temperate regions throughout the world except extreme northern areas. In the tropics Aphis gossypii is a major pest of cotton. Aphis (Aphis) gossypii Glover, 1877: UKSI Synonym Source; Aphis gossypii Glover, 1877 synonym: UKSI Classification unranked Biota kingdom Animalia phylum Arthropoda subphylum Hexapoda class Insecta order Hemiptera family Aphididae genus Aphis species Aphis gossypii. Greenhouse crops are damaged by numerous aphid pests, but a few highly polyphagous species, including green peach aphid Myzus persicae, melon aphid Aphis gossypii, potato aphid Macrosiphum euphorbiae, and foxglove aphid Aulacorthum solani, are of primary importance (Chow and Heinz, 2004). One of the major pests of Cucurbitaceae is the cucumber aphid, Aphis gossypii Clov., syn. It is distributed almost worldwide, and is particularly abundant in the tropics. A Manual of the Insects of the Hawaiian Islands, including Enumeration of the Species and Notes on Their Origin, Distribution, Hosts, Parasites, etc. Aphis gossypii is a tiny insect or greenfly in the superfamily Aphidoidea in the order Hemiptera.It is a true bug and sucks sap from plants. In the former Soviet Union it is found up to 54°N. A. gossypii has a worldwide distribution, although in arctic regions it is mostly confined to glasshouses. The structure of Vip1A is not known, but a region with alternating hydrophobic and hydrophilic residues within this protein was identified, and it was proposed that it could adopt a structure of a β-strand that would be important for membrane penetration forming a β-barrel necessary for translocation of the Vip2A component, similar to other bacterial toxins such as protective antigen (PA) of anthrax toxin from B. anthracis, the Iota Ib toxin from C. perfringens, and the C2-II toxin from Clostridium botulinum [40]. Morphometric variation of A. gossypii … Due to their specific activity against D. virgifera, this binary toxin was cloned into corn plants. The mean threshold for developmentis estimated at 6.2ºC; generational time is 4.5 days at the optimal temperature of … Crystal structure of Vip2A toxin. Several species of aphids are commonly found on citrus. Aphis gossypii (Glover) is distributed worldwide and causes substantial economic and ecological problems owing to its rapid reproduction and high pesticide resistance. To solve this problem, a Vip2 zymogen with lower actin-ADP-ribosylating activity than the wild type was constructed using protein engineering with a proper extension of the polypeptide chain. [3] These mature in about twenty days at 10 °C and in about four days at 30 °C. It thrives outdoors in southern Europe but survives only under glass in northern Europe. Several members of the Aphidiinae and Aphelinidae wasp families are parasitoids of aphids. Heavy infestations cause stunting of host plants; toxic substances injected during feeding also cause abnormal growth. A study on the distribution pattern of Aphis gossypii Glover and its coccinellid predator, Menochilus sexmaculatus Fabricius, was conducted in a chilli ecosystem at the experimental field of Universiti Putra Malaysia. Within-plant distribution of cotton aphids, Aphis gossypii Glover (Hemiptera: Aphididae), in Bt and non-Bt cotton fields. [1], Carbamates and organophosphates are commonly used against A. gossypii around the world. [3] Winged forms then migrate to secondary host species in the families Rosaceae, Chenopodiaceae, Malvaceae, Cruciferae, Cucurbitaceae, Solanaceae, Compositae and others. They damage sweetpotato plants by sucking sap from growing shoots causing wrinkling, cupping, and downward curling of young leaves. : orange, mandarin, tangerine, clementine, grapefruit, pomelo, lemon and lime, Postharvest Biology and Technology of Tropical and Subtropical Fruits: Açai to Citrus, Postharvest Biology and Technology of Tropical and Subtropical Fruits: Mangosteen to White Sapote, Mechanism of action of Bacillus thuringiensis insecticidal toxins and their use in the control of insect pests, The Comprehensive Sourcebook of Bacterial Protein Toxins (Fourth Edition), Microbial Control of Mite and Insect Pests of Greenhouse Crops. Aphis gossypii is a tiny insect, an aphid ("greenfly") in the superfamily Aphidoidea in the order Hemiptera. In Europe it reproduces exclusively by asexual reproduction and can produce nearly fifty generations a year under favourable conditions. Other vegetable crops attacked include pepper, eggplant, okra and asparagus. OCT/1991 . [3], The wingless female cotton aphid has an ovoid body about two millimetres long in varying shades of green. A study on the distribution pattern of Aphis gossypii Glover and its coccinellid predator, Menochilus sexmaculatus Fabricius, was conducted in a chilli ecosystem at the experimental field of Universiti Putra Malaysia. The oval eggs are yellow when first laid but soon turn glossy black. Copyright © 2021 Elsevier B.V. or its licensors or contributors. & Roff, M.N.M. These oligomers insert into the membrane, forming pores with high conductance in the black lipid bilayer [40]. The 3D structure and PDB accession number are shown here, with the structure alignment with the NAD-dependent ADP-ribosyltransferase domain of the Iota toxin from C. perfringens (performed with the jFAT-CAT algorithm). [1] It is a major pest of cotton and cucurbits. It has a very wide host range with at least 700 host plants being known world-wide. The population of A. gossypii and the incidences of CVMV and CMV on bell pepper were evaluated under four types of production systems. Aphis gossypii, on the other hand, tends to remain initially on the upper leaves of chrysanthemum but eventually redistributes to lower leaves (Vehrs et al., 1992). Hence, they reduce the crop yield and reduce its market value. However, there is evidence that on a global scale the name A. gossypii is being applied to a number of forms with different life cycles and/or host-plant associations.
