Winged Aphid

Information about the seasonal occurrence and peaks of activity of winged aphid species was obtained by trapping during a period of 15 months at three locations within 45 miles of Melbourne. Most species were caught in greatest numbers during either the spring or the autumn. Species such as Myzus persicae (Sulz.) and Brevicoryne brassicae (L.) were caught throughout the year. Cavariella aegopodii (Scop.) was trapped only in cool weather, while Aploneura lentisci (Pass.) was caught only in warm weather. Water-filled yellow trays were very efficient for trapping many species, but a wind-vane sticky trap caught more of some species, including the grass-feeding aphids, than did the yellow tray.

AbstractDispersal of apterae from their natal plant was monitored for three aphid species (Myzus persicae (Sulzer), Brevicoryne brassicae (Linnaeus) and Megoura viciae Buckton), each on a different host plant. Some movement off the plant occurred even in the initial parental and second generations, when the plant appeared to be growing normally and when crowding was unlikely to be the cause. However, in most experiments the most marked increase in apterous dispersal coincided with a reduction or even cessation of plant growth. In nearly all the experiments this dispersal occurred when the population on the natal plant exceeded about 20 adults and their offspring per plant. The main emigrants were fourth instar apterae and prelarviposition adult apterae. The implications of this behaviour are discussed, and it is argued that apterous dispersal might be common in aphids, allowing a fuller utilization of the environment than would be likely by alate dispersal alone.

"The cosmopolitan aphid species Myzus persicae is a key pest of peach orchards in south and southeastern Romania. The phenomenon of resistance induced by the intensive use of insecticides is a matter of concern for farmers and protectionists, making necessary integrated measure for the control of this pest. Conservation of natural enemy’s populations is an essential component of any management system proposed for pest aphids. The aim of the study was to determine the structure of predatory insects associated with Myzus persicae populations in peach orchards. The research was carried out in three orchards from two localities from Constanta County, in peach plantations with Springcrest variety aged 7, 11 and 12 years. As a result of this study, there were determined a total of 15 predatory insect species belonging to eight systematic families: Coccinellidae, Chrysopidae, Hemerobiidae, Syrphydae, Cecidomyiidae, Panorpidae, Nabidae and Forficulidae, which naturally contribute to the reduction of the green peach aphid populations.

The aim of this study was to evaluate the potential of entomopathogenic fungi (EPF) for the control of aphid pests of field vegetable crops. Four biopesticides based on the EPF Beauveria bassiana (Botanigard ES and Naturalis L), Cordyceps fumosorosea s.l. (Preferal WG), and Akanthomyces dipterigenus (Vertalec) were evaluated in a laboratory bioassay against peach-potato aphid Myzus persicae, cabbage aphid Brevicoryne brassicae, and currant-lettuce aphid Nasonovia ribisnigri. There was significant variation in the spore dose provided by the products, with Botanigard ES producing the highest dose (639 viable spores per mm2). Botanigard ES also caused more mortality than the other products. Combining Vertalec with the vegetable oil-based adjuvant Addit had an additive effect on the mortality of B. brassicae. All fungal products reduced the number of progeny produced by M. persicae but there was no effect with B. brassicae or N. ribisnigri. When aphid nymphs were treated with Botanigard ES and Preferal WG, both products reduced population development, with up to 86% reduction occurring for Botanigard ES against M. persicae. In a field experiment, Botanigard ES sprayed twice, at seven-day intervals, against B. brassicae on cabbage plants, reduced aphid numbers by 73%. In a second field experiment with B. brassicae, M. persicae, and N. ribisnigri, Botanigard ES reduced populations of B. brassicae and N. ribisnigri but there was no significant effect on M. persicae.

Myzus persicae (Sulz.) transmitted a new virus to healthy Physalis floridana Rydb. from other P. floridana infected with a turnip latent virus complex. Symptoms were characterized by a chlorosis and sometimes cupping of only the lower leaves with slight stunting of plants. These symptoms could easily be mistaken for those incited by potato leaf roll virus but they were strikingly different from the yellow netting of plants infected with the turnip latent virus complex.In virus–vector studies with the new virus and M. persicae, an occasional aphid acquired the virus in 2 hours and 14% of infective insects transmitted it in 30 minutes. When acquisition and inoculation feedings were each increased to 48 hours, transmissions by single aphids of 70% and more were common. A few aphids transmitted the virus in a total transmission time of 30 hours, but most required 72 hours or longer to acquire, become infective, and transmit it.In comparative tests between the new virus and either potato leaf roll or the turnip latent complex, the new virus and potato leaf roll were recovered from plants 3 days after inoculation but the complex was not recovered for 14 days or longer. Of five aphid species tested, M. persicae was an efficient vector of all three viruses and the only species to transmit the new virus and the turnip latent complex. Plants infected with the new virus and showing symptoms were as easily infected with potato leaf roll as were comparable controls, but fewer of them became infected with the complex. The new virus and the complex were quite similar in host range, and susceptible plants were found in the Amaranthaceae, Chenopodiaceae, Cruciferae, and Solanaceae.The new virus is called mild chlorosis virus of P. floridana.

Indirect application was used to assay the toxicity of five insecticides; viz. malathion, carbosulfan, cymbush, imidacloprid and azadirachtin against four important crop infesting aphid species, Aphis craccivora Koch, Aphis gossypii Glover, Myzus persicae (Sulzer) and Lipaphis erysimi (Kaltenbach), reared on bean, brinjal, potato and cauliflower plants respectively. Residual film technique was applied by bringing leaves with tested aphids of the vegetable plants in the laboratory. Malathion was the least toxic to all aphids having LC50 as 327.97, 333.92, 305.26 and 313.77 μg cm-2 for A. craccivora, A. gossypii, M. persicae and M. persicae respectively. Cypermethrin was the most toxic showing LC50 as 12.55, 12.29, 12.55 and 12.10 μg cm-2 in the above mentioned species of aphid respectively. Carbosulfan and imidacloprid showed moderate toxicity. Azadirachtin as a natural plant origin insecticide proved to be the most toxic having LC50 as 0.41 μg cm-2 for A. craccivora, 0.34 μg cm-2 for A. gossypii and 0.44 μg cm-2 for both M. persicae and L. erysimi.
