Abstract : The seasonal incidence of the geometrid Thalassodes dissita, the noctuids Bombotelia jocosatrix and Chlumetia transversa, the lymantriid Laelia sp., the gracillariid Acrocercops syngramma, the attelatid Deporaus marginatus, the scarabaeid Popillia sp. and the pseudococcid Drosicha mangiferae was studied in a mango nursery in Maharashtra, India, for 1 year from June 1983. The pests appeared in June-July and their incidence was high in July-October after which it declined. Phorate 10G, carbofuran 3G, monocrotophos (at 0.1% as a drench and at 0.04% as a spray), endosulfan (at 0.1%), carbaryl (at 0.2% as a drench and as 10% dust), BHC [HCH] (at 0.2% as a drench and as 10% dust), dimethoate (0.03%), cypermethrin (0.005%) and permethrin (0.005%) were tested for the control of these insects in kharif 1984. All the insecticides tested reduced the incidence of insect pests. All the treatments except carbaryl drench had equal efficacy against T. dissita and all except HCH drench were equal against B. jocosatrix. All the insecticides except endosulfan and monocrotophos drench were effective against A. syngramma. Against C. transversa, only monocrotophos drench was ineffective, and all except carbaryl drench and phorate were effective against D. marginatus.
