Description
Byline: Marghub Amer, Muhammad Aslam, Muhammad Razaq and Sarfraz Ali Shad - Email: mrazaq_2000@yahoo.com Abstract.- Conventional (bifenthrin, carbosulfan and methamidophos) and neonicotinoid insecticides (thiamethoxam and imidacloprid) were sprayed once to test their toxicity to cabbage aphid, Brevicoryne brassicae L. and turnip aphid, Lipaphis erysimi (Kalt.) on canola. Insecticides were applied on 14th March, 2005 at Multan. After seven days of application all the insecticides proved to be similarly toxic to aphids but statistically higher numbers of both aphid species were observed in untreated plots. In another experiment split plot design was employed and four B. napus varieties, CON-I, CON-II, KS-75 and Abaseen were planted in sub-plots keeping insecticides (thiamethoxam, imidacloprid and carbosulfan) in main plots at Dera Ghazi Khan. Insecticides were applied on 2nd and 12th March, 2006. The interaction between varieties and insecticides at the Dera Ghazi Khan trial was non-significant when analyzed in split plot design.
