abstract
Considerable loss is observed in valuable timbers during storage due to attack by several insect pests among which the bamboo borer is of primary concern which can attack from a moisture range of 8 to 30%. In the present study a total of 6 treatment schedules viz. soaking in water (T₂), Brushing with turpentine oil (T₃ 0, Dipping the log with Turpentine oil (T₄), Brushing with primer (T₅) and dipping in primer for 15 minutes (T₆) including an untreated check were standardised. Countable numbers of insects (20) were released at a month interval up to 3 months. Treatment-2 recorded 30% of mortality after 3months of treatment. T₃ recorded as high as 80% of mortality after 1^st release, 70% mortality in 2^nd release and 60% mortality in 3^rd time release. T₄ provides full protection up to 1 month with a record of 100% mortality and 85.00% and 70.00% mortality during 2^nd and 3^rd release of the test insect. T₅ recorded a mortality of 75.00% after the 1^st release and 70.00% after third release. However, T₆ recorded mortality of 85.00% after 1^st release, 75.00% after 2^nd release, and 70% after 3^rd release. Hence, all the treatments except T₂ was found at par in providing protection against powder post beetle attack after 3 months duration.
