A sex pheromone release system of pear borer worm

Abstract

The invention discloses a pheromone release system of the small pear borer worm, which comprises a support base, a base installed on the upper end of the support base, and a conical top cover installed above the base through a mounting column. The mounting column has a rectangular parallelepiped structure. A number of storage tanks for placing the sex pheromones of pear borer worms are respectively arranged on the front and rear sides, and each storage tank is equipped with a movable sealing cover, and the inner side wall of the movable sealing cover is connected with the side of the installation column through two sets of cylindrical air bags, and Each group of cylindrical airbags is equipped with a set of springs, and the base is installed with an inflation and deflation pump for inflating the cylindrical airbags. The inflation pump is connected to the cylindrical airbags through an inflation tube with a solenoid valve, and the peripheral cover of the column is installed. A metal braided grid cover is provided, and a circle of charged columns is arranged on the periphery of the metal braided grid cover. The invention can adjust the release of pheromones according to the pest activity rules, occurrence conditions, weather conditions, etc., so as to ensure the prevention and control effect and avoid the waste of pheromones.

Description

technical field [0001] The invention relates to the field of pest control, in particular to a sex pheromone release system for the pear borer moth. Background technique [0002] The small pear borer is a worldwide fruit tree pest, which eats the fruits or new shoots of various pome fruits and stone fruit trees such as pears, peaches, and apples with larvae. At present, chemical pesticides are mainly used for control in production practice, resulting in increased resistance of pear borer, serious fruit and environmental pollution and other problems. [0003] Insect pheromones have the advantages of high efficiency, non-toxicity, no harm to natural enemies, no pollution to the environment, no resistance, and wide application areas. They are widely used in agricultural and forestry pest control. With the development of science and technology, more and more attention has been paid to the use of insect pheromones to prevent and control pests, which is one of the green prevention...

Problems solved by technology

[0004] However, at present, sex pheromones still have many deficiencies in the application of interfering mating and trapping and killing, mainly including: 1. Sex pheromones are easy to volatilize and degrade under in vitro conditions, and the effective concentration and effective period of different sex pheromones Different, some existing release devices cannot adjust and control the release rate and release cycle according to the specific characteristics of sex pheromones, which will easily lead to high volatilization in the early stage and low later stage, making it difficult to exert its best performance and obtain the best control effect ;

[0005] 2. The current release device is a continuous release, which cannot be adjusted according to the occurrence of pests, resulting in the release of pheromones in vain during the non-adult stage of the pests or when the adults are inactive, or the release of the same amount of pheromones when the pests occur at different levels, which affects the prevention and control Effect
