Field trials were conducted consecutively for two years 2013 and 2014 at research farm of ICAR-National Research Centre on Litchi, Bihar to develop the eco-friendly techniques for managing the ash weevil, Myllocerus undecim pustulatus (Coleoptera: Curculionidae) which is one of the major defoliators of litchi causing severe damage to the new flush resulting poor growth of the plant. Maximum (15.33) population of ash weevil was recorded in 40th standard week (SW). No population of ash weevil was noticed in 1st to 3rd standard week. Again new generation of ash weevil population was seen in 4th SW with 1.33 adult populations and maximum 7.67 populations were recorded in 13th standard week. Thiamethoxam (12.6% )+ Lambdacyhalothrin (9.4%) @ 0.098% was highly effective with 0.00 population against 10.67 in control followed by chlorfenapyr 10 EC (0.03%) and imidacloprid 17.8 SL (0.0089%) as registered 0.33 and 1.67 weevil population respectively after three days spraying. Weevil population can be effectively managed by two sprays of thiamethoxam (12.6%) + lambdacyhalothrin (9.4%) @ 0.098% or chlorfenapyr 10 EC @ 0.03% at 30 days interval during September and October.
