A field evaluation of a number of insecticides against Tirathaba rufivena was undertaken in a mature oil palm plantation at Teluk Intan between April and October 1988 over an area of 6.5 hectares.
The insecticides evaluated were endosulfan, diflubenzuron, cyfluthrin and Bacillus thuringiensis Berliner (Thuricide). The insecticides were applied three times at fortnightly intervals. Experimental controls were set up a) with no chemical treatment and b) using a cultural practice to maintain good sanitation.
