A control plot that received only water was also maintained. Two species of Podagrica, P. sjostedti (Jacoby) and P. uniformis (Jacoby), Aphis gossypii (Glover) and Thrips tabaci (Linderman) were collected on okra. In both seasons, karate, karate + 1% and karate + 2% alata samina significantly (P < 0.05) reduced the aggregations of the insects than the control. A. gossypii, T. tabaci, and B. tabaci Gennadius were collected from the tomato plots. Karate, karate + 1% and 2% alata samina significantly reduced aggregations of the insects as compared to the untreated plots. Significantly (P < 0.05) less number of Bemisia tabaci aggregated on the karate + 2% alata samina treatment plots in the major and minor cropping seasons. With regard to okra, significantly (P < 0.05) fewer T. tabaci, A. gossypii and Podagrica spp. were collected from the plots that received applications containing karate, in the major season. Similar results were obtained in the minor season for T. tabaci and A. gossypii but, significantly fewer Podagrica spp. were collected on the karate + 2% alata samina treatment plots. Application of karate + 2% alata samina significantly (P < 0.05) reduced damage to tomato fruits compared to fruits on the untreated control plots in both the major and minor seasons. Significantly (P < 0.05) less percent defoliation was recorded on the karate-treated plots than the untreated control plots in both seasons. Karate + 2% alata samina application also significantly (P < 0.05) increased yield of tomato in both seasons. Significant increase in yield of okra was obtained from the karate + 2% alata samina plots, but no significant differences were obtained in the number of damaged okra fruits. The best protection of the crops against the insect pests was obtained from weekly applications of karate + 2% alata mixture.
