the mustard aphid, lipaphis erysimi kalt, is one of the most severe pests of brassica species in iran and other tropical regions in the world. seven cultivars of three brassica species including b. napus (cv. licord, elite, okapi, hyola 401, and rgs003), b. juncea (cv. land race) and b. rapa (cv. park land) were evaluated to study the antixenosis and antibiosis resistance to l. erysimi under gr...

The exorbitant yield loss incurred by Indian farmers every year (10-90%) in rapeseed-mustard (Brassica juncea) is chiefly attributed to the progressive infestation of mustard fields by Lipaphis erysimi (Kalt.), a major insect pest belonging to the family of Homoptera. Currently there are no successful tolerant cultivars developed by conventional means in Brassica juncea with systemic plant resp...

A field trial was conducted at Central Research Field, SHUATS, Naini, Prayagraj during rabi 2021 in Randomized Block Design (RBD). Seven treatments were evaluated against Lipaphis erysimi i.e., Imidacloprid 17.8% SL @ 0.5ml/lit, Thiomethoxam 25%WG 4 gm/lit, Neem oil 5ml/lit, Indoxacarb 14.5%SC@ 0.65 ml/lit, Emamectin Benzoate 5% SG, seed kernel extract (NSKE) 5 Spinosad 45% SC. Results revealed...

Headed cabbage (Brassica oleracea L.) is a leafy vegetable facing enormous damage by insect pests. To deal with these insects, chemical control remains the main method used its harmful consequences on environment and human health. The objective of this study to evaluate effects intercropping head field mint (Mentha arvensis white verbena (Lippia alba (Mill.) N. E. Brown) pests yield. So, trial ...

This study aimed to evaluate the quality of the aphid Myzus persicae (Sulzer), Lipaphis erysimi (Kaltenbach) and Brevicoryne brassicae (L.) as hosts for the parasitoid Diaeretiella rapae (McIntosh). Parasitization by D. rapae was higher on M. persicae than on L. erysimi and B. brassicae. The time of development of D. rapae from egg to mummy or egg to adult male or female were shorter on M. pers...
