Influence of trash mulch and weeds on the incidence of stalk borer and abundance of the predaceous ant Crematogaster subnuda Mayr in sugarcane.

摘要

Investigations on the influence of trash mulch and weeds in sugarcane revealed significantly higher populations of the predatory ant, Crematogaster subnuda Mayr in trash mulched and weedy fields and lower incidence of stalk borer, Chilo auricilius (Dudgeon) than the controls. This reduction in the incidence was also corroborated by laboratory and field tests.
