Problems solved by technology
[0006] The technical problem to be solved by the present invention is to provide a sparsely distributed sex pheromone releaser that automatically adjusts the release time and speed of sex pheromones to solve the problem of sexual information in the prevention and control of traditional insect sex pheromones. Sex pheromones are easily oxidized and invalidated, and they are released uncontrollably around the clock, resulting in waste and high cost of sex pheromone prevention and control

Embodiment 1
[0031] In the field, the sex pheromone releaser of the present invention is used to control the small pear borer in the Taoyuan of Jingshen Village, Beiwang Township, Taigu County, Shanxi Province, and the test area is compared with the control area.
[0032] Table 1 Control effect of pear small mist directional lure and sex pheromone releaser
[0033]
[0034] The result shows 220 / 667m 2Pear small fan lure core and 1 / hm 2 Sex pheromone releaser has the same control effect on pear borer.
[0035] Table 2 Dense type and duration of sex pheromone releaser
[0036]
[0037] The duration of the dense-distributed maze lure was significantly longer than that of the sparse-distributed sex pheromone releaser, and the number of replacements was significantly higher.
[0038] Table 3 Cost of Lure Lures and Sex Pheromone Releasers
[0039]
[0040] From the total cost, it can be seen that the cost of dense prevention and control is as high as 620 yuan / 667m when the preventio...
Embodiment 2
[0042] The sex pheromone releaser was used in the field to control the peach borer in the jujube garden of Wangjiaozhuang Village, Houcheng Township, Taigu County, Shanxi Province, and the experimental area was compared with the control area.

Abstract
The invention discloses a sparse distribution type sex pheromone releaser which comprises a first cavity (1), a second cavity (2) and a liquid container (11), wherein the bottom of the first cavity (1) is connected with the bottom of the second cavity (2), the first cavity (1) can contain the second cavity (2) to form an outer cavity (4) which is filled with liquid, inner space of the second cavity (2) forms an inner cavity (3), two kinds of openings or notches which are formed alternately are formed in the lower end of the first cavity (1) and the lower end of the second cavity (2), the openings or notches, belonging to one kind, are communicated with the inner cavity (3) and outer space, sex pheromones in the inner cavity (3) can be released to the outer space through a large arc opening (8), and the openings or notches, belonging to the other kind, are communicated with the outer cavity (4) and the outer space. The releaser solves the problems that in traditional insect sex pheromone isotropic prevention, waste is caused, and sex pheromone prevention cost is high due to the fact that the sex pheromones are easily oxidized to lose efficacy, are uncontrollable and are released in an all-weather mode.
Description
technical field [0001] The invention relates to a sex pheromone releaser for preventing and controlling agricultural and forestry pests, in particular to a device for controlling the release rate of sex pheromone, especially a releaser that can control the release of sex pheromone to stop during the day and start to release at night. Background technique [0002] Insect pests are one of the important problems restricting agricultural production, often causing large-scale crop production reduction or even failure, resulting in serious economic losses. [0003] In my country, the application of sex pheromones has been successfully used to prevent and control pests. Usually, insect traps are used to trap and kill pests; or sex pheromones are used to interfere with the mating of pests. In the interference mating, there are two types: dense distribution and sparse distribution. The densely distributed type often adopts directional lures or oriented filaments, and the sparsely dist...
