Abstract

NEW MATERIAL:A 1-halo-3-decene expressed by the formula (X is halogen). EXAMPLE:1-Bromo-(Z)-3-decene. USE:An intermediate for producing a sex pheromone acting substances against peach fruit moth (injurious insect of apples and peaches). PREPARATION:3-Decyn-1-ol is reduced to give 3-decen-1-ol, which is then halogenated to afford the aimed compound expressed by formula I . The resultant compound is then reacted with magnesium to give the novel corresponding Grignard reagent, which is reacted with a compound expressed by formula II (n is an integer 5-8) to afford a novel substance expressed by formula III. The resultant novel substance expressed by formula III is oxidized to give a compound, expressed by formula IV, and having the above-mentioned action. The compound expressed by formula IV (n is 7 or 8) exhibits more improved above- mentioned action than the compound expressed by formula IV (n is 5 or 6), and the Z isomer shows more improved action than any other isomer or a mixture thereof.

Among insects, during their mating behavior, adult females secrete and emit a special trace amount of a substance ζ.As a result, male adults are sexually stimulated and are attracted to the female adult, which is the source of the substance.
There are many cases of mating. Such substances, or groups of substances, are generally referred to as sex pheromones or sex attractants, and are factors that control important stages of mating behavior in insects. By using sex pheromones to attract and capture male adult pest insects, or by artificially concealing the normal mating behavior of male adult insects, pest density can be reduced and pests can be controlled. In addition, the results of regional surveys to determine whether sex pheromone '+= attracts male adults will be useful in determining the appropriateness and timing of spraying insecticides, and determining their effectiveness.
Efforts are also being made to promote the proper use of pesticides and to reduce the amount of pesticides used.
