Forty-six compounds (17 alcohols and 29 acetates) were tested electrophysiologically (electroantennograms) at 100 µg/cartridge on 4 species of lepidopterous insects (male and female Diatraea grandiosella , Dyar, male and female Manduca sexta , (L.), male Heliothis virescens (F.), and male Platynota stullana Walsingham). Those compounds eliciting the greatest response were tested at lower concentrations until a response was no longer obtained. Responses were compared with those elicited by a methylene chloride extract of abdomens of virgin females of the same species. Compounds eliciting the greatest responses for males at the lowest concentration were the acetates of 7-octen-1-ol, 8-nonen-1-ol, trans-5 -decen-1-ol, cis- 6-doclecen-1-ol, trans -6-dodecen-1ol, dodecen-1-ol, cis-8-dodecen-1-ol, and ris-9-dodecen- 1-ol. and tralls-2-hexen-1-ol. Of these compounds, 8-nonen- 1-ol acetate elicited a response from male M. sexta at a dose of 10-0 µg.

In a series of laboratory tests and in field tests in commercial greenhouses, methomyl and Azodrin®(3-hydroxy- N -melhyl- cis -crotonamide dimethyl phosphate) gave excellent control of larvae of the tortricid leaf roller Platynota sultana (Walsingham). Trichlorfon, Matacil® (4-(dimethylamino)- m -tolyl methylcarbamate), and Bacillus thuringiensis Berliner gave as good control as the standard Zectran® (4-dimethylamino-3,5-xylyl methylcarbamate). Eighteen other insecticides gave unsatisfactory control at the doses used, and Dursban® ( O, O -diethyl O -3.5,6-trichloro-2-pyridyl phosphorothioate), though it gave excellent control, was phytotoxic to rose plants.
