Description Insecticide resistance and concomitant field failures to control the cotton bollworm,
Helicoverpll Ilnlzigera (Hiibner), were first recorded in south India in 1987. During the
1992-93 cropping season a discriminating dose technique ,vas used to routinely monitor
resistance in four major cotton- and pulse-growing areas o f Andhra Pradesh State. Very high
levels of resistance to pyrethroids, and significant endosulfan and organophosphate resistance
were a feature of all regions monitored. The intensity of expression was determined by local
selection pressure and mixing of populations by windborne migration agai ns t a changing
background of insecticide use across seasons. Levels of piperonyl butoxide-insensitive
pyrethroid resistance were hi gher in the more intensive insecticide-use regions. Farmers are
applying more frequent and higher doses of insecticides, often as mixtures, in an attempt to
control
.
(IRM) rationale, resulting in greater
implementation of insecticide-resistance management
control over the use of insecticides, is urgently needed to reduce the resistance selection
pressure on conventional insecticides and to conserve susceptibility to ne wer insecticides and
biorationals with novel modes of action. Constraints and prospects for IRM implementation
in India are discussed.
