Investigation of termite attack, Macrotermes gilvus Hagen (Termitidae: Blattodea), to cocoa (Theobroma cacao)

Abstract

Macrotermes gilvus is a major pest in the cocoa cultivation industry in Indonesia, with huge productivity. The success of a termite control technology is largely determined by the availability of information about the biology of termites which are pests. Investigating M. gilvus attacks was surveyed on polyculture cocoa plantations in Pidie, Aceh Tamiang, and Southeast Aceh Districts, Aceh Province. We found various levels of termite attacks characterized by mounds (nests) and galleries on the cocoa. The presence of nests and galleries damages the pith tissue and creates empty spaces, which are later filled with soil. Lack of land sanitation can trigger termite attacks on the plantations.
