Yield losses due to mustard aphid, Lipaphis erysimi (Kalt.) The cabbage aphid can be distinguished by its waxy coating and its dense colonies on young growth, while the green peach aphid is dispersed around the brassica plant, occurring mainly on the older leaves of its host. stream CAB Direct is the most thorough and extensive source of reference in the applied life sciences, Extensive online help - available wherever you are in CAB Direct. session so others can sign in.

The tuber yield per plant was recorded at each harvest separately for each treatment and the yield is converted to kg/plot. 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. Winged females are able to disperse to other plants, but produce fewer offspring. Field studies were carried out for two consecutive rabi seasons (2005-06 and 2006-07) to screen certain rapeseed-mustard varieties for their resistance against mustard aphid, Lipaphis erysimi and to evaluate the bioefficacy of certain botanical and microbial insecticides. Thiamethoxam, imidacloprid, and dimethoate were best and effective chemicals in reducing the population of aphids, whereas the two microbial pesticides were found to be less effective. Wingless males have occasionally been seen; these are smaller than the females and olive-green to brownish in colour.

It is one of several species of aphid to feed on brassicas; the cabbage aphid (Brevicoryne brassicae) feeds only on these plants, while the green peach aphid is found on many crops and plants including brassicas. Lipaphis erysimi is a species of aphid of the family Aphididae. 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.

[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. Lipaphis erysimi Culture. Cabbage seedlings were planted during the major andminor seasons of 2015 in 3 x 3 m plots and the treatments used included Chlorpyrifos, Lambda-cyhalothrin,hot pepper, Capsicum futescens fruit extract, neem, Azadirachta indica seed extract, solution of local soap(alata samina) with water as a control. CAB Direct provides Its common names include mustard aphid and turnip aphid. %PDF-1.5 One of the … Their impact on predators, pollinators and crop yield were also evaluated. About 50 insects are known to damage Brassica crops. 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. Modelling regional level spatial distribution of aphid (Lipaphis erysimi) growth in Indian mustard using satellite-based remote sensing data. 1 0 obj Ten cabbage leaves per treated plot were randomly sampledweekly into 70% alcohol to obtain actual counts of aphids and their natural enemies. Cole Crops Other Aphids Scientific Names: Green peach aphid: Myzus persicae Turnip aphid: Lipaphis erysimi (Reviewed 6/07, … The antennae and legs are dark, and the cornicles are black at the base and yellowish towards the tips.

The winged female is a similar size and has a black head and thorax and a pale green abdomen with black bands near the tip and black patches on the sides. The wingless female is pale green or whitish green with two rows of dark bands on the thorax and abdomen which unite into a single band near the tip of the abdomen. It is extremely prolific and in warm places such as Texas, a maximum of thirty-five generations per year have been recorded. MANAGEMENT OF LIPAPHIS ERYSIMI (KALT.) endobj MANAGEMENT OF LIPAPHIS ERYSIMI (KALT.) 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.

[6], This aphid is found on older leaves of brassica plants and on the roots. The first spray was given after 18 days of sowing when sufficient buildup of aphid population was seen.

The control and biopesticide treated plots recorded the highest numbers ofthe natural enemies (hoverflies, ladybirds and spiders). 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.
