Abstract
Four different insecticid.aplcaricide5 viz, ntrvai;ron 40 Sew, monitor 50 EC, plictran 50 Wr and danitol 10 EC each in two different doses of 0.05 and ill% were tried against cucurbit mite, Teranjvh$ cucurbitne Rahnian and Sapra., a serious pest of cucurbit vegetables especially bitter gourd. All the four insecticideslacari-rides proved quite ei-Ttetive in controlling the pest. Nuvacrou oil z, however, gave the highest mortality of 100 and 93.19%, respectively, of nymphs and adults, while danitol 0.05% gave the minimum mortality of 27.55% and 24.14%, respectively, of nymphs and adults at 96 hours after spray.
INTRODUCTION
The attack of vegetable mite, retranychus cuctirbitae Rahman. and Sapra is usually Irrory common on hitter-gourd, causing serious losses in the years of heavy infestation. Although the biology of this mite has been extensively stu-died, yet very few attempts have been. made in. Pakistan to find out effective and economic control of this injurious species. In other parts of the world workers like Bast' and Prarnanik (1969), Singh et aL, -(1975), Dhooria and Mann (1980), G:ra 0930) and Pande and Reddy 0982) tried different pesticides for the control of Tetranyaus spill, on different crops and obtained good control of this serious pest. The informations regar-ding chemical control of this pest species in Pakistan is rather scanty. Mohsin (1963) conducted research on the control of Tetranychus spp, in this region using two acaricides viz. duphar tedion V.18 and phankapton and obtained good con-trol of the pest,
MATERIALS AND METHODS
