INFLUENCE OF INTERCROPS ON INCIDENCE OF SHOOT AND FRUIT BORER, Leucinodes orbonalis Guenee

Abstract

Studies were taken up to understand the chemical ecology of Leucinodes orbonalis using
intercrops. Studies on Intercrops coriander and cluster bean in brinjal caused reduction of L. orbonalis
damage in the main crop. The mean of shoot damage observed in coriander intercropped plot was 6.19 per
cent and was 8.05 per cent in cluster bean intercropped plot whereas in sole crop damage reported was 14.48
per cent. The Fruit damage observed was 57.52 per cent in sole crop and was only 37.16 per cent in coriander
intercropped plot and 50.64 per cent in cluster bean intercropped plot. To identify intercrops as a “push
factor strategy” in L. orbonalis management, coriander and cluster bean crops were evaluated.
