Management of chalcid wasp (Systole albipennis) (Eurytomidae: Hymenoptera) in coriander: a pest of field and quarantine significance

Abstract

Field experiment on management of chalcid wasp [Systole albipennis (Walker)] on coriander crop was conducted during season 2008-09 and 2009-10 using different treatments such as manipulation of date of sowing, application of plant products and synthetic insecticides. The result revealed that late sown crop (15 November) suffered less seed damage while yield was also recorded lower in late sown crops. Among plant products efficacy of neem products was found superior over karanj products for control of the chalcid wasp. Among different neem formulations, application of neem oil 2% gave superior result than other neem products as minimum average of 3.5% seed damage and highest seed yield of 9.70 q/ha was obtained. Among insecticides, spray of thiamethoxam 0.025% and imidacloprid 0.005% provided maximum protection (5.25 and 5.20% seed damage against 16.2% in the control).
