Title Sex Pheromone Systems of Selected Lepidopterous Pests of Groundnut
 
Creator Lalitha Kumari, V L
 
Description 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.
