Components of integrated pest management (IPM) technology developed for diamondback moth (DBM) Plutella xylostella (Linn.), in the lowland include the release of larval parasitoid, Cotesia plutellae (Kurdj.) supplemented with selective insecticide based on economic threshold level. The technology was transferred to farmers through the training of trainors and farmers followed by farmer-participated demonstration farms (FPDF). The training was conducted in cooperation with local government units (LGU), state colleges and universities (SCU) and farmer associations. A total of 1,154 farmers and 176 trainors from 31 municipalities of 9 provinces of Batangas, Camarines Sur, Cavite, Ilocos Norte, Laguna, Nueva Ecija, Rizal and Quezon [Philippines] were trained and 49 FPDF were set-up in 7 provinces. High C. plutellae parasitism and cocoons and lower DBM population were noted in IPM than farmers control practices (FCP) fields. The farmer adoption of IPM technology resulted in the increase of net income ranging from US$2,781 to 10.98/ha, 5-78% higher than FCP due to lower production cost and higher yield. The production cost per hectare ranged from US$1,104 to 3,902, 2 to 45% lower than FCP. Insecticide application was reduced to 1-4 times in Quezon and 3-9 in Ilocos Sur and Norte from 15-36 times before the piloting of the technology. The increase in net income varied with the location, season, production cost and price of cabbage
