Do beetles indicate more predators and fewer pests in Lao PDR organic farms?
Published online by Cambridge University Press: 04 February 2025
Summary
Agricultural intensification has led to significant species losses and has been associated with a decline in ecosystem services provided by insects. In Asia, particularly in Lao PDR (Southeast Asia), biodiversity-friendly agricultural practices such as the production of organic crops have been promoted to address these challenges, although intensification has continued. In this study, we examined beetle community composition in three organic farms (using, for example, manure and compost and not employing synthetic fertilizers and pesticides) and three conventional farms (using, for example, synthetic fertilizers and insecticides) in Vientiane (Lao PDR). Our results indicate that total beetle abundance was similar between farm types, while species richness was greater, predators were over 18 times more abundant and insect pests were 9 times less abundant in organic compared to conventional farms. These findings can inform government organic farming policy in Lao PDR and the promotion of sustainable agriculture in Southeast Asia generally.
