Mishra, Y.D., Sushil, S.N., Sharma, K.K., Bhattacharya, A., & Jaiswal, A.K. 1996 Efficacy of selected organophosphorus insecticides for control of Chrysopa madestes (Neuroptera: Chrysopidae) - a serious sporadic predator of Indian lac insect, Kerria lacca (Kerr).. New Agriculturist 7: 17-20.
Notes: Dichlorvos and malathion were evaluated against eggs and different larval instars of C. madestes. Application of insecticides directly to eggs did not affect egg hatchability. The larval instars were exposed to filter paper impregnated with insecticides for 6 h, continuously and transferred to clean petri dishes subsequently for 24 h observation. The three instars showed different susceptibility to various concentrations of the insecticides tested. Dichlorvos at 0.03% was found most suitable for control of the predator.
