Studies on Mealybugs and their Natural Enemies in Ber Orchards
Ber (Zizyphus mauritiana (L.)) has been found attacked by four mealybugÂ species viz., Nipaecoccus viridis (Newstead), Planococcus citri (Risso),Â P. lilacinus (Ckll.) and Maconellicoccus hirsutus (Green) around Bangalore.Â A total of 11 natural enemies on N. viridis, three on P. citri and two onÂ P. lilacinus were recorded. Attempts were also made to use the exotic naturalÂ enemies like Cryptolaemus montrouzieri Muls. and Leptomastix dactylopiiÂ How to suppress the mealybug population in ber orchards. The localÂ parasitoids and predators appeared in large number and were mainlyÂ responsible for the suppresion of N. viridis and P. citri on ber.
