Biochemical mechanism of resistance in some Brassica genotypes against Lipaphis erysimi (Kaltenbach) (Homoptera: Aphididae)
*Corresponding author E-mail : [email protected] INTRODUCTION The genus Brassica comprises an important group of cultivated vegetable and oilseed crops and have great economic importance worldwide. The cultivated species of Brassica include cabbage, cauliflower, kale, broccoli, Brussels sprouts, turnip, swede, oilseed rape, various mustards and other leafy vegetables (Hong et al. 2008). As oils...
متن کاملInfluence of PGRs on carbohydrate content in Lipaphis erysimi (Kalt.).
Six compounds (IBA, chlorogenic acid, cytokinine, GA3, alar B-9 and maleic hydrazide) belonging to four different categories of plant growth hormones were used to study their effect on carbohydrate content in L. erysimi. The second instar nymphs (48 hr old) were given both dipping and leaf surface treatment with 1024 ppm concentration of compounds for two time intervals i.e. 48 and 96 hr. The c...
متن کاملActivity of eleven enzymes in nymphs of Lipaphis erysimi as affected by 2,4-D (herbicide) treatment
The activity of eleven enzymes involved in development, ageing and in metabolism of xenobiotics in insects, was investigated under the influence of 2,4-D (2,4-Dichlorophenoxyacetic acid), in the mustard aphid, Lipaphis erysimi (Kaltenbach) (Rhynchota Aphididae), after treating the 2 instar nymphs for 13, 25 and 37 h. Studies of two hydrolases and one group transfer enzyme revealed significant e...

متن کاملGenetic polymorphism of factor B (Bf) in Okayama Prefecture, Japan.
The genetic polymorphism of factor B (Bf) was investigated in Okayama Prefecture, Japan. Cellogel immunofixation electrophoresis was employed according to Martin and Ziegler (1981) with minor modifications. In 316 non-blood related Japanese, the Bf was: Bf S, 70.6%; Bf FS, 27.8%; and Bf F, 1.6%. No rare variants were observed. The gene frequencies of Bfs and BfF were 0.845 and 0.155, respective...
