In a laboratory trial Bacillus thuringiensis var. tenebrionis adversely affected survival of Chauliognathus lugubris (F.) (Coleoptera: Cantharidae), a major predator of the target insect Chrysophtharta bimaculata. Survival of two coccinellids and adult C. bimaculata was not affected. the pyrethroid cypermethrin adversely affected all insects tested. Both cypermethrin and B. thuringiensis are used to control C. bimaculata larvae in Tasmanian eucalypt plantations.
