Abstract

The invention discloses a cydia pomonella sex pheromone microcapsule embedding method. According to the method, Arabic gum, maltodextrin and starch sodium octenylsuccinate are taken as the wall material of a microcapsule, and the raw material proportions of the composite wall material are as follows: 1-2 parts of Arabic gum, 2-3 parts of maltodextrin and 3-5 parts of starch sodium octenylsuccinate. The ratio of a core material and the wall material is as follows: the ratio of cydia pomonella sex pheromone to the wall material is 1:10-1:30. Tween 20 and Tween 80 are used to prepare a composite emulsifier and the ratio of Tween 20 to Tween 80 is 1:1-1:2. The ratio of the composite emulsifier to the core material is 1:5-1:10. The high-pressure homogenization pressure is 10-20 MPa. The spray drying conditions for the microcapsule are as follows: the air inlet volume is 500-900 L / h, the material charging speed is 180-540 mL / h and the air inlet temperature is 130-170 DEG C.

Description

technical field [0001] The invention relates to the technical field of a codling moth sex pheromone microcapsule embedding method. Microcapsules are used to embed the codling moth sex pheromone to prolong the medicinal effect time of the codling moth sex pheromone and strengthen the mating effect of the codling moth. purpose of interference. Background technique [0002] Codling moth is a major pest that harms apples, and it is also the most serious fruit tree pest in Xinjiang Autonomous Region. In recent years, codling moth has become a frequent and important pest in many fruit areas in my country, seriously harming nut fruit trees, and the area of ​​the disaster is increasing, with a tendency of increasing year by year and developing from west to east. [0003] At present, the control of codling moth mainly depends on chemical pesticides, but because the moth has the habit of boring, the larvae soon bore into the fruit after hatching, chemical pesticides can not play a go...
