Embodiment 1

[0012] Preparation of a pear borer pheromone microcapsule: the ratio of the wall material is gum arabic: maltodextrin: sodium starch octenyl succinate = 1:3:5, the ratio of the core material and the wall material is the pear borer sex pheromone : Wall material = 1: 10, the ratio of emulsifier to core material is composite emulsifier: core material = 1: 10, and the homogeneous pressure is 20MPa. The optimal spraying conditions for microcapsules are: air intake volume 700L / h, feed rate 360mL / h, air intake temperature: 170°C.

[0013] Use: Pear borer worm sex pheromone microcapsules combined with sticky insect boards are placed in orchards and other places where pear borer frequents and cause harm.

[0014] Attraction effect: We conducted an experiment in an orchard A in Korla City, Xinjiang, and placed 3 sticky boards with pear borer microcapsules per mu, and placed one piece every 50 meters. After 30 days, each sticky board averaged Attract 12 small pear borer worms.

Embodiment 2

[0016] Preparation of a pear borer pheromone microcapsule: the ratio of the wall material is gum arabic: maltodextrin: sodium starch octenyl succinate = 1:3:5, the ratio of the core material and the wall material is the pear borer sex pheromone : Wall material = 1: 10, the ratio of emulsifier to core material is composite emulsifier: core material = 1: 10, and the homogeneous pressure is 20MPa. The optimal spraying conditions for microcapsules are: air intake volume 700L / h, feed rate 360mL / h, air intake temperature: 170°C.

[0017] Use: Pear borer worm sex pheromone microcapsules combined with sticky insect boards are placed in orchards and other places where pear borer frequents and cause harm.

[0018] Attraction effect: We conducted an experiment in the B orchard of Korla City, Xinjiang, and placed 3 sticky boards with pear borer microcapsules per mu, and placed one piece every 50 meters. After 30 days, each sticky board averaged Lure 10 small pear borers.

Embodiment 3

[0020] Preparation of a pear borer pheromone microcapsule: the ratio of the wall material is gum arabic: maltodextrin: sodium starch octenyl succinate = 1:3:5, the ratio of the core material and the wall material is the pear borer sex pheromone : Wall material=1:10, the ratio of emulsifier and core material is composite emulsifier: core material=1:10, homogeneous pressure 20MPa. The optimal spraying conditions for microcapsules are: air intake volume 700L / h, feed rate 360mL / h, air intake temperature: 170°C.

[0021] Use: Pear borer worm sex pheromone microcapsules combined with sticky insect boards are placed in orchards and other places where pear borer frequents and cause harm.

[0022] Attraction effect: We conducted an experiment in the C orchard of Korla City, Xinjiang, and placed 3 sticky boards with pear borer microcapsules per mu, and placed one piece every 50 meters. After 30 days, each sticky board averaged Lure 14 small pear borers.

Abstract

The invention discloses a grapholitha molesta sex pheromone microcapsule embedding method. According to the grapholitha molesta sex pheromone microcapsule embedding method, Arabic gum, maltodextrin and starch sodium octenylsuccinate are taken as the wall material of a microcapsule, and the raw material proportions of the wall material is as follows: the ratio of Arabic gum to maltodextrin to starch sodium octenylsuccinate is 1:3:5. The ratio of a core material and the wall material is as follows: the ratio of grapholitha molesta sex pheromone to the wall material is 1:10. The ratio of an emulsifier to the core material is as follows: the ratio of a composite emulsifier to the core material is 1:10. The high-pressure homogenization pressure is 10-20 MPa. The spray drying conditions for the microcapsule are as follows: the air inlet volume is 700 L / h, the material charging speed is 360 mL / h and the air inlet temperature is 170 DEG C.

Description

technical field [0001] The invention relates to the technical field of a microcapsule embedding process for the sex pheromone of the pear borer worm. By adopting the microcapsule embedding of the sex pheromone, the drug effect time of the sex pheromone of the pear borer worm is prolonged and the mating interference of the little pear borer is strengthened. . Background technique [0002] Pear borer is the main pest of pears, peaches and apricots. In recent years, the small pear borer has become a frequent and important pest in many fruit areas in my country, seriously endangering fruit trees, and the area of ​​the disaster is increasing, and there is a trend of increasing year by year. [0003] At present, the prevention and control of pear borer mainly depends on chemical pesticides, but the insect has the habit of boring. Once the larvae eat into the shoots or fruits, chemical pesticides cannot play a good effect. At the same time, chemical control has caused pests Drug ...
