DescriptionThirteen insecticides were tested against Ips paraconfusus Lanier, and six against the western pine beetle (Dendroctonus brevicomis Lec.). The ranking of toxicity at LD90 by topical application to I. paraconfusus was: SD 3450 > endosulfan > malathion > lindane > phorate > carbayl > carbophenothion = Imidan > crotoxyphos > dimethoate > DDT > Dilan > trichlorfon. The ranking of toxicity to D. brevicomis was: Zectran = dichlorvos > Dursban > malathion > pyrethins = Endane. Five compounds-Zectran, Dursban, malathion, dichlomos, pyrethrins-show promise for study as possible alternatives to lindane, which is now commonly used for bark beetle suppression.
