Abstract

Crickets and grasshoppers are insects that are often found in longan plantations. According to several studies that have been conducted, grasshoppers and crickets play an important role in plantation ecosystems, including longan plantations. Grasshoppers can act as pests and crickets can play a role in the decomposition of soil organic matter.
