Insecticides for Control of the Lone Star Tick Tested in the Laboratory and as High- and Ultra-Low-Volume Sprays in Wooded Areas13

Abstract
The most effective insecticides tested in the laboratory as residues on filter paper against nymphs of the lone star tick, Amblyomma americanum (L.), were Bay 39007 (o-isopropoxyphenyl methylcarbamate), Banol® (6-chloro. 3,4-xylyl methylcarbamate), Shell SD-8530 (3,4,5-trimethyl. Phenyl methylcarbamate), Schering 34615 (m-eym-5-yl methylcarbamate), Dursban® (O,O-diethyl O.3,5,6-trichloro-2-pyridyl phosphorothioate), naled, and dichlorvos. When high-volume sprays were applied to small plots in wooded areas (0.1-0.2 hectare) infested with nymphsand adults of the lone star tick, Dursban, diazinon, fenthion, and Sumithion® (Bay 41831) (O,O-dimethyl O nitro-m-tolyl phosphorothioate) gave good control at l.12 and 2.24 kg per hectare and were at least as effective as DDT. Aerial ultra-low-volume (ULV) applications of fenthion gave good control of lone star ticks at 2.24 kg/hectare but only fair control at 0.56 and l.12 kg/hectare. Ground ULV applications gave good control at doses of fenthion and Bay 39007 as low as 0.56 kg per hectare.
