Weaver Ant: a natural ecological practice to protect cashew nut plantations

Did you know weaver ants are helpful for pest control?
Weaver ants are considered farmers’ friends as they protect crops like cashews from pests. Introducing weaver ants is just one of many techniques used in Agroecological Crop Protection (ACP), which combines the principles of agroecology, Integrated Pest Management (IPM), Organic Agriculture, and regenerative agriculture.
This natural solution reduces crop damages, improves yields and nut quality, ends the need to spray chemical pesticides, reduces production costs and increase’s farmers profit margins. Moreover, it maintains the health of farmers and the environment while also improve the resilience of farming systems.

Watch this video to learn about weaver ant management techniques and the successful experiences of organic cashew farmers in Preah Vihear province.

Weaver ant, a natural ecological practice to protect cashew nut plantations

Weaver ants (Oecophylla smaragdina, Hymenoptera) have been used for more than 2,000 years for the suppression of insect pests in Asian mango and citrus orchards, thus constituting the oldest known example of biological control in agriculture. Yet, in the Mekong Delta, pockets of smallholder farmers are still conserving weaver ant populations and relying upon these beneficial insects to keep pests at bay, especially in cashew plantations. Weaver ants are found naturally in organic plantations but their benefits are often unknown, as far as the possibility of increasing their population as a way to manage insect pests.

Testing Agroecological Methods to Manage Pests in Cashew Production

The cashew sector is heavily reliant on chemical inputs, raising concerns for both environmental and human health. In response, the Green Cashew project (2022–2025) aims to promote agroecological and climate-resilient farming practices among cashew producers. The research aims to test agroecological solutions focused on improving soil fertility, pest and insect management, and reducing flower drop. An economic assessment will help determine whether these practices are viable and scalable for
wider adoption.
