These aphids have a slightly visible thin layer of white, waxy secretions (much less than the cabbage aphid). At present, there is a great deal of discussion on the resistance and resurgence of insects to commonly used insecticides which is of grave concern in crop protection. The insects are almost exclusively female and are very prolific, with wingless females producing around one hundred young during a lifespan of a few weeks. <>/XObject<>/ExtGState<>/ProcSet[/PDF/Text/ImageB/ImageC/ImageI] >>/MediaBox[ 0 0 595.32 841.92] /Contents 4 0 R/Group<>/Tabs/S/StructParents 0>>

The current findings suggest that the crudeneem seed extract, and to some extent local soap, alata samina, and pepper, are effective and safe optionsfor managing aphids on cabbage. From each tagged plant, three leaves were selected from the upper, middle and lower part for counting the number of aphids per leaf with help of magnifying lens and the mean population of aphids per plant was worked out. USING NEWER INSECTICIDES AND BIO-PESTICIDES IN RADISH. Like most websites we use cookies. It is extremely prolific and in warm places such as Texas, a maximum of thirty-five generations per year have been recorded. Modelling regional level spatial distribution of aphid (Lipaphis erysimi) growth in Indian mustard using satellite-based remote sensing data. Their impact on predators, pollinators and crop yield were also evaluated. Life table and growth rate studies on Lipaphis erysimi in relation to Brassica varieties. At present, there is a great deal of discussion on the resistance and resurgence of insects to commonly used insecticides which is of grave concern in crop protection.

The control and biopesticide treated plots recorded the highest numbers ofthe natural enemies (hoverflies, ladybirds and spiders). in promising genotypes of Brassica juncea. [6] The wingless females produce up to six offspring per day over a period of twenty to forty days, a total of eighty to one hundred young. International Journal of Pest Management: Vol. Hence, an attempt has been made to evaluate newer insecticides and bio-pesticides to manage aphids Lipaphis erysimi (Kalt.) Both the nymphs and adults of the pest damage to the crop by sucking cell sap from leaves, inflorescence, pods and cause 70-80% yield losses. Thecurrent study sought to investigate the effect of commonly used management options on the populationof aphids, Lipaphis erysimi pseudobrassicae (Davis) and Myzus persicae (Sulzer) (Hemiptera: Aphididae),their natural enemies and the yield of cabbage. <>/PageLabels 369 0 R>>
