"Insecticide resistance and concomitant field failures to control the cotton bollworm,\r\nHelicoverpll Ilnlzigera (Hiibner), were first recorded in south India in 1987. During the\r\n1992-93 cropping season a discriminating dose technique ,vas used to routinely monitor\r\nresistance in four major cotton- and pulse-growing areas o f Andhra Pradesh State. Very high\r\nlevels of resistance to pyrethroids, and significant endosulfan and organophosphate resistance\r\nwere a feature of all regions monitored. The intensity of expression was determined by local\r\nselection pressure and mixing of populations by windborne migration agai ns t a changing\r\nbackground of insecticide use across seasons. Levels of piperonyl butoxide-insensitive\r\npyrethroid resistance were hi gher in the more intensive insecticide-use regions. Farmers are\r\napplying more frequent and higher doses of insecticides, often as mixtures, in an attempt to\r\ncontrol\r\n .\r\n (IRM) rationale, resulting in greater\r\nimplementation of insecticide-resistance management\r\ncontrol over the use of insecticides, is urgently needed to reduce the resistance selection\r\npressure on conventional insecticides and to conserve susceptibility to ne wer insecticides and\r\nbiorationals with novel modes of action. Constraints and prospects for IRM implementation\r\nin India are discussed.\r\n"^^ . "1994" . . . . . . . . . . . . . . "N J"^^ . "Armes"^^ . "N J Armes"^^ . . "P A"^^ . "Lonergan"^^ .
