Abstract
Bamboos suffer from insect damage, in varying degree, right from the seed to the finished products by as many as 212 insect species. Chlorophorus annularis (Cerambycidae: Coleoptera) is one of the serious pests on dry bamboo. Three preservatives, viz., CCB (Copper sulphate, Chrome and Boric acid), Borax and ZiBOC (Copper sulphate, Borax, Zinc chloride) at 6 per cent concentration by pressure, and dipping method were used for the control of C. annularis. CCB 6% preservative after 7 days of dipping yielded a maximum of 76.62 average per cent borer control in dry bamboo followed by 4 days of dipping (71.17%), 2 days of dipping (48.06%) and after 1 hour of dipping (45.88% borer control). Preservatives used for the control of bamboo borer damaging cut and dry bamboo were quite effective and the methodology applied was environmentally safe. For post-harvest management of dry bamboo, ZiBOC or CCB 6% preservative after 7 days of of dipping is recommended for effective borer control.
