Evaluation of some control methods against the jackfruit trunk borer, Batocera rufomaculata de geer (Cerambycidae: coleoptera)

Abstract

The study was conducted on effectiveness of different management practices of the trunk borer infestation in farmers’ jackfruit orchards at Kapasia upazila under Gazipur district of Bangladesh during 2009-2010. Among the ten treatments, the T5 (placing aluminium phosphide + sealed hole with bordeaux paste) ensured the highest (83.33 %) control of infestation and the highest increase in yield (51.30%) over the control. The cost: benefit of T6 (placing aluminium phosphide into the hole + sealing the hole with cow dung) (1:10.21) was higher than T5 (1: 7.75) but in terms of infestation control and total yield T5 was higher than T6.Bangladesh J.
