The peak incidence of whitefly (62.12mean population/6 leaves) and leafhoppers (68.24 mean population/6 leaves) were observed in first week and second week of November, respectively and fruit borer (55.7 mean population/6 leaves) in February first week. The average maximum (30.3°C) and minimum temperatures (16°C), average morning (90%) and evening relative humidity (34%), coccinellids (2.70 mean population/6 leaves) and spiders (1.89 mean population/6 leaves) in case of B. tabaci and in case of A. devastans, average maximum (29.6°C) and minimum temperatures (16.1°C), average morning (90%) and evening relative humidity (41%), coccinellids (2.80 mean population/6 leaves) and spiders (2.23 mean population/6 leaves) was noticed. Correlation between population environmental parameters have done and explained.
