Impact of integrated pest management in rice and maize in the Greater Mekong Subregion
Published: October, 2019
Between 2011 and 2016, CABI and the Institute of Plant Protection, Chinese Academy of Agricultural Sciences (IPP-CAAS) led two integrated pest management (IPM) projects in Southwestern China, Laos and Myanmar, which promoted the adoption of biological pest control among rice and maize farmers. The project focused on the establishment of Trichogramma rearing facilities (TRFs) for the production of Trichogramma egg-cards, which act as an effective biocontrol agent for maize and rice, as well as training farmers in IPM practices. At the end of 2017, CABI conducted an extensive assessment of the sustainability of TRFs and the impact of the interventions on IPM adoption in the target areas.
After rice, maize is the most important crop in the Mekong Delta. Insects including the Asian corn borer are a major threat to production. Fear of crop losses, together with a lack of alternative measures, can result in overuse of pesticides – posing health risks to farmers, consumers and the agro-ecosystem. This project will establish local production of an affordable biological control agent, the parasitic wasp trichogramma, which kills the eggs of maize pests.

Rice is the most important crop in southwestern China, Laos and Myanmar. Despite recent improvements, productivity is still low with millions of tons lost to pests, diseases and weeds. Intensive pesticide use has led to insecticide resistance, outbreaks of secondary pests and damage to farmers’ health. This project is introducing a biologically based pest management approach to safely and sustainably increase rice production, improving the livelihoods of smallholder farmers in the region.
