There are several natural enemies of Heliothis armigera (Hbn.), which m the absence of pesticides, often maintain the pest populations below threshold levels. Thus there is a need to gather infonnation on the natural enemy complex available in the ecosystem so as to determine the vacant niches. Survey was undertaken at fortnightly intervals during 1983-85 to record the natural enemies in H. armigera in Coimbatore district of Tamil Nadu where pulses were grown more commonly during 1983-85.

Abstract


There are several natural enemies of Heliothis armigera (Hbn.), which m the absence of pesticides, often maintain the pest populations below threshold levels. Thus there is a need to gather infonnation on the natural enemy complex available in the ecosystem so as to determine the vacant niches. Survey was undertaken at fortnightly intervals during 1983-85 to record the natural enemies in H. armigera in Coimbatore district of Tamil Nadu where pulses were grown more commonly during 1983-85.
