Abstract

The incidence of L. orbonalis on brinjal was noticed in different dates. The result obtained from the present study revealed that among the three different dates of transplanting of brinjal, the crop transplanted 15th of May recorded the lowest mean shoot infestation (9.87 per cent) and fruit infestation on number (9.66 per cent) as well as on weight basis (8.83 percent) as compared to the crop transplanted on 15th of June, which recorded mean shoot infestation of 13.33 per cent and mean fruit infestation of 21.70 per cent on number basis and 19.91 percent on weight basis. This could be attributed to the less population build up of L. orbonalis on the crop transplanted on 15th of May as compared to the crop transplanted on 15th of June.
