It was studied the effect of insecticides Neonicotinoids: Mospilan 20 SP–300 g ha – 1 , Calypso 480 SC–300 ml ha –1 , Proteus 110 OD–700 ml ha –1 ; Pyrethroids: Duet 530 EC–500 ml ha –1 , Nurelle D–40 ml ha –1 and Fury 10 EC–100 ml ha –1 on Bruchus pisorum eggs under field conditions during 2011 and 2012. The insecticides were applied at the time of the first egg occurrence on lower pods. It was found that the females of B. pisorum laid more than 60% of the eggs in the form of two eggs clusters. The treatment with Mospilan, Fury, Proteus and Calypso significantly reduced the rate of pea weevil eggs survival compared to control. Mospilan 20 SP (300 g ha –1 dose) had the lowest level of B. pisorum eggs survival (37.7 %) and the highest ovicidal efficacy (51.63 %). From the comparison of the mean pea weevil eggs survival and efficacy, expressed separately for the group of pyrethroid and neonicotinoid insecticides, the neonicotinoid group emerged as significantly more effective.
