Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a plum, an important pest of plum fruit, called Pumomosimingui (scientific name: Graphol).
The present invention relates to an attractant for a Plum Butterfly containing a sex pheromone substance as an active ingredient, which is capable of predicting its spawning time and performing pest control by attracting ita dimorpha) to various insect traps. 2. Description of the Related Art Plum trees are important pests of plums that damage fruit of plums. Eggs laid on the fruit surface hatch after 2-3 days and immediately invade the fruit. Since the terminal larva inhabits the fruit, the period during which the insecticide reaches the pest, the so-called optimal period of control, is very short, a few days after the spawning. [0003] A pheromone trap is known as a method for predicting a suitable time for controlling pests. However, there is no knowledge about sex pheromones and sex attractants of the pests, and the pheromone traps could not be used to predict the occurrence of the pests. .
Therefore, in the current plum cultivation, insecticides are sprayed on this pest prophylactically.However, due to the above-mentioned ecological characteristics, timely control cannot be realized, resulting in damage, and further excess insecticide is sprayed. There are many cases. In addition, there is a problem that this excessive spraying kills natural enemy organisms in the field and causes secondary insect pests such as mites and scale insects. SUMMARY OF THE INVENTION An object of the present invention is to provide an attractant containing a sex pheromone substance as an active ingredient, which is effective for grasping the occurrence of Pluminella edulis. . Means for Solving the Problems To solve the above problems, the present inventors screened using various compounds exhibiting sex pheromone activity against lepidopteran pests.
(E) -8-dodecenyl acetate (hereinafter referred to as E8-DD
A is also abbreviated. ) And (Z) -8-dodecenyl acetate (hereinafter also abbreviated as Z8-DDA), and the mixture weight ratio is (20:80) to (60:40). The present inventors have found that the attractant specifically attracts the adult male of this species, and as a result, it is possible to predict the occurrence of Plumeria mellifera, thereby completing the present invention. [0006] (E) contained in the attractant of the present invention
-8-Dodecenyl acetate and (Z) -8-dodecenyl acetate can be produced by known methods. (E) -8-dodecenyl acetate and (Z)
The mixing weight ratio with -8-dodecenyl acetate is (2
0:80) to (60:40). This is because if it is out of this range, it will not be possible to attract the plums. When using the attractant of the present invention, an appropriate amount of an antioxidant such as butylhydroxytoluene, butylhydroxyanisole, hydroquinone, or vitamin E or an ultraviolet absorber such as 2-hydroxy-4-octoxybenzophenone may be added. Suitable amounts are E8-DDA and Z8-DDA
For example, the antioxidant is 1 to 5% by weight and the ultraviolet absorber is 1 to 5% by weight based on the total weight of The attractant of the present invention has a function of controlling the release amount of rubber, polyethylene, polypropylene, ethylene-vinyl acetate copolymer, polyvinyl chloride, etc., in order to maintain a constant amount of the active ingredient released over a long period of time. It is used by filling in containers such as caps, thin tubes, laminated bags, capsules, etc. made of materials having the same. EXAMPLES Hereinafter, specific embodiments of the present invention will be described with reference to examples and comparative examples, but the present invention is not limited to the examples. Examples 1-4, Comparative Examples 1-6 Types of sex pheromone substances used as attractants in Table 1,
The composition and the amount used are shown. After adding 2.0% by weight of butylhydroxytoluene to these, each was supported on a rubber cap made of isoprene, and allowed to stand overnight.
Attached to a white sticky trap. Each trap in which each attractant was set was hung at a regular height at intervals of 5 m in a plum field in which the occurrence of Plum Tree Sparrow was observed.
At the interval of every 5 days, the number of adult adults of Prunus persicae captured in each trap was counted. The invitation parameters from May to September are shown in Table 1. [Table 1] Although none of the attractants of Comparative Examples 1 to 5 was attracted, Examples 1 to 4 showed that attraction was observed. Further, as the attractant of Comparative Example 6, (8E, 10E) -8,10-dodecenol (E8
Also abbreviated as E10-DDOH. ), But none of them were attracted. According to the present invention, it is possible to obtain an effective attractant for specifically attracting male adults of Plum-bellied mosquitoes and knowing the occurrence status.
