Abstract

Controlling Cricula trifenestrata Helf. on cashew trees.

Abstract

Cypermethrin (Cymbush 5 EC at 1.5 ml/litre), fenvalerate (Sumicidin 5 EC at 1.0 ml/litre), acephate (Orthene 75 SP at 1.0 g/litre), fenitrothion (Sumithion 50 EC at 1.5 ml/litre) and a mixture of carbaryl and endosulfan (Sevidan 75 SP 1.5 g/litre) were applied with a knapsack sprayer for the control of the saturniid Cricula trifenestrata on cashew trees in Indonesia. Leaves from different parts of the trees were fed to larvae. Spraying with a power sprayer at a rate of 5 litres/tree gave complete coverage. Fenvalerate and cypermethrin were the most effective, resulting in 94.44 and 79.16% larval mortality, respectively, 7 days after treatment.
