Components of the integrated pest management (IPM) technology for diamondback moth (DBM), Plutella xylostella in the lowland include the release of larval parasitoid, Cotesia plutellae, supplemented with selective insecticide based on economic threshold level. The technology was transferred to farmers through training of trainers [technicians of the local government units (LGU) and researchers of state colleges and universities (SCU)] and farmers followed by farmer-participated demo farms (FPDF). The training was conducted in cooperation with LGU, SCU and farmer associations. A total of 1,154 farmers and 176 trainers 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 setup in 7 provinces. High C. plutellae parasitism and cocoon formation and lower DBM population were noted in IPM than FCP fields. The farmer adoption of IPM technology resulted in the increase of net income ranging from US$2,781.25 to US$10,984/ha, 5-78 percent higher than FCP due to lower production cost and higher yield. The production cost per hectare ranged from US$1,104.16 to 3,902.34, 2 to 45 percent 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. Seventy to 100 percent of the cooperators regularly visited by the AVNET personnel and trainers properly implemented the IPM technology while only 30 percent succeeded among cooperators who were not regularly visited.
