JPH08245310A - Attractant for bluegrass webworm - Google Patents

Abstract

PURPOSE: To provide an attractant for bluegrass webworm (Parapediasia tererrella) having strong attracting action compared with a sex pheromone known as a conventional attractant for bluegrass webworm. CONSTITUTION: This bluegrass webworm attractant contains at least one component selected from anisic acid methyl, ethyl or propyl ester and/or at least one component selected from phenylacetaldehyde, 3-phenylpropionaldehyde and cinnamaldehyde. The attracting effect is further improved by mixing the above active component of the bluegrass webworm attractant with (Z)-11- hexadecenal and (Z)-9-hexadecenal.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is applied to the leaf moth (scientific name: Parapediasia teterrellus Zincke) belonging to the family Lepidoptera: Pyralidae.
n, common name Bluegrass webworm) attractant.

2. Description of the Related Art Shibatatsuga is seen every year in the plains west of the Kanto region, and causes great damage to turfgrass and the like on golf courses.

Generally, in order to effectively control the damage caused by pests, there is a method of exterminating the pests with an insecticide.
However, when a conventional insecticide was used in this method, it was difficult to sufficiently control the damage caused by the grasshopper.

Therefore, a new pest control method using an attractant has been proposed. That is, prior to the extermination of pests,
An attractant is used for investigation of the occurrence of fever, insects are killed with bait containing attractant and insecticide, and insect pests are attracted and then killed by a mechanical method such as a trap. When this method is used in the control of grasshopper, (Z) -11-hexadecenal and (Z) -9-hexadecenal, both sex pheromones, are used as an attractant in a weight ratio of 1

0)). Further, the above-mentioned attractant is disclosed in JP-A-4-243802.
It is also described in the official gazette. Further, an attractant containing a mixture of 100 parts by weight of (Z) -11-hexadecenal, 5 to 10 parts by weight of (Z) -9-hexadecenal and 0.01 to 1 part by weight of (Z) -11-hexadecenol as an active ingredient. Have also been reported (JP-A-6-56608 and 6-40809). However,
The attracting agents containing these sex pheromones as the active ingredients were not sufficient in their attracting action, and therefore, the controlling effect on the grasshopper was not sufficient.
