An improved insect pest management package of technology was developed to increase the seed cotton yield and the income of the farmers. The package includes the following practices: a. Application of carbofuran (Furadan) along the furrows at planting; b. planting of okra as trap crop for flower weevil within the periphery of the area planted to cotton; c.) releasing Trichogramma as biological control agent against bollworm; d. application of carbofuran (Furadan) by dibbling near the base of the cotton plant at 55 days after planting; and e.) spraying insecticides when out of 20 plants following number of bollworm population is reached - vegetative to squaring stage (22-63 DAP)-3 larvae, flowering stage (64-84 DAP)-2 larvae and bolling stage (85-105 DAP)-3 larvae. The improved version provided the cotton farmers a 16% increase in yield or an additional income of P2,921/ha. This is in addition to its positive impact on environment due to reduced number of sprayings
