Abstract

A pioneering study was conducted in farmers’ fields to determine the effect of planting flowering plants in field margins close to rice fields on the population of the different functional groups of arthropods, key insect pests, and natural enemies, and damage caused by stemborer and defoliators in farmers’ fields. Sampling rice arthropods using sweep net and Blow-vac suction machine showed that rice fields close to field margins with flowering plants had lower population of herbivores compared to fields without flowering plants. Parasitoids collected using yellow sticky traps were higher in fields close to flowering plants compared to those without. This was recorded in both locations. In addition, damage caused by defoliators and stem borer were higher in fields without flowering plants compared to fields close to flowering plants. Ecological engineering offers immense opportunities to rice insect pest management using non-chemical methods leading to economic, health and environmental benefits.
