Abstract

Insect pests constitute one of the major constraints impeding the groundnut production in our country. While 70 insect species have been reported to damage; leafminer (Aproaerema modicella rev.) and red hairy caterpillar (Amsacta albistriqa Wlk.1 havt been considered to be major pests of this crop. Of late, tobacco caterpillar (Spodoptera litura Fab.1 and gram caterpillar (Heliothis armiqera Hub.) which were secondary pests of groundnut, have now assumed serious jest status particularly during post rainy season. The matter of serious concern in the last few years is that these pests acquired resistance to commonly used insecticides (Reddy and Rosaiah, 19871 including the synthetic gyrethroids and thus leading to greater losses in yield due to the danagr of these pests. The leafminer intensity and damage has also been ascending in the recent years (Amin, 1987) due to changes in the cultivars and the intensity of management practices. Serious losses due to leaf miner are often caused because of non-perception of the time of application of insecticides. Even in the red hairy caterpillar which causes total damage but sporadically, the time of occurence of the pest and of insecticidal application has been visualised as major bottleneck.
