The periodic incidence of different sucking pests on okra during the crop season was significant at different period of crop growth. The period mean revealed that the aphid population was reached to its peak level (27.17 aphids / 3 leaves) during 14th weeks after sowing (first week of July). The aphids were considered as sucking insect pests. The population of aphids was more abundant on the crop during June and July 2011. Results revealed that maximum activity was recorded during July and the correlation studies were made between the incidence of major sucking insect pests and select weather parameters. Aphids showed positive correlation with rainfall (r = 0.261) and negative correlation with both maximum and minimum temperature. Aphids showed positive correlation with relative humidity.
