Estimating the term…
The invention relates to a composite insect attractant for male white-line dart moths [Scotia segetum] containing 7[Z]-dodecen-l-ol acetate of the formula [I] ##STR1## and 9[Z]-tetradecen-l-ol acetate of the formula [II] ##STR2## as active agents in a weight ratio of I to II of [50-99]:[50-1], optionally along with a liquid or solid adjuvant. Another object of the invention is an insect trap containing said composition and a process for attracting and trapping male white-line dart moths as well as a process for disrupting their mating by air permeation technique. The invention relates further to a novel process for the preparation of the active ingredients of the composition.
A composite insect attractant for male white-line dart moths, containing 7(Z)-dodecen-1-ol acetate of the formula I ##STR8## and 9(Z)-tetradecen-1-ol acetate of the formula II ##STR9## in a weight ratio of 50 to 99:50 to 1 as active ingredients.
A process for disrupting the mating of white-line dart moths, which comprises emitting into the atmosphere a combination of 7(Z)-dodecen-1-ol acetate and 9(Z)-tetradecen-1-ol acetate in a weight ratio of 50 to 99:50 to 1 with a speed of 5.0-30 mg/hectare/hour.
A process for attracting and trapping male white-line dart moths which comprises the step of exposing said moths to an insect trap which comprises a sheet smeared with glue and with a combination of 7(Z)-dodecen-1-ol acetate and 9-(Z)-tetradecen-1-ol acetate in a weight ration of 50 to 99:50 to 1 in a total amount of 0.01 to 10.0 mg.
