The adults of L. brunneus were liberated into a petri dish, in which treated wood alone (single arrangement), or together with untreated wood (twin arrangement) was placed.In single arrangement, no or few ovipositions were observed in the wood treated with permethrin at concentrations which were not lethal to the adults. In twin arrangement, the adults laid eggs in the untreated wood, but not in the treated wood even at the lowest concentration (2.0 ppm). Evidently, the adults avoided the wood treated with permethrin for oviposition. Ovipositions occurred on wood treated with lindane as well as on untreated wood in the same petri dish, though the total number of eggs laid decreased with the concentration of lindane. In the case of fenitronhion, the number of eggs was larger in the untreated wood than in the treated wood. For example, no egg and 24 eggs were laid in the treated and untreated wood, respectively, at the highest concentration (2000 ppm). There was a large difference in the effects on oviposition of the three insecticides.
