Abstract
The invention discloses a cydia molesta pheromone liposome embedding technology. Lecithin and starch sodium octenylsuccinate serve as a lipidosome wall material; the ratio of lecithin to starch sodium octenylsuccinate is 1: 5; the ratio of cydia molesta pheromone serving as a core material to the wall material is 1: 10; the homogenization pressure is 30Mpa; the liposome spray drying conditions are that the air inlet amount is 500L/h, the material feeding speed is 270mL/h, and the air inlet temperature is 150 DEG C.
Description
Technical field
The present invention relates to the liposome embedded technology of a kind of sex pheromone of Grapholitha molesta field, adopt liposome embedded sex pheromone, reach and extend sex pheromone of Grapholitha molesta effective drug duration, strengthen the object that oriental fruit moth mating is disturbed.
Background technology
Oriental fruit moth is the primary pest of harm pears, peach and apricot.In recent years, oriental fruit moth has become the normal property the sent out important pests in many fruits district of China, serious harm fruit tree, and Disaster Area is increasing, has the trend increasing the weight of year by year.
Main dependence chemical pesticide control oriental fruit moth at present, but because this worm has the moth of boring habit, once larva eats into into the tender tip or fruit, chemical pesticide just can not play good effect.This has increased the difficulty of control oriental fruit moth undoubtedly.
Both at home and abroad the research of insect sex pheromone and application are all taken much count of, extensive use is to utilize insect sex pheromone to disturb mating to carry out large-area control of insect the most.Be usually used at present disturbing the formulation of mating control to have hollow fibre, plastic sandwich, natural rubber core and microcapsules etc.Wherein microcapsules are comparatively desirable formulations, because insect sex pheromone microcapsule preparation process is easy, isolated illumination, air and moisture, reduced the oxidized speed with decomposing of active component, can control constant release and keep longer action time; Simultaneity pheromones microcapsules can adopt traditional spraying equipment to use, and have reduced artificial input and have increased the flexibility that regulates and controls delivery rate and number of times.
Therefore, the liposome embedded technique of exploration non-environmental pollution control sex pheromone of carpocapsa pomonella is imperative.
Summary of the invention
The invention reside in and cause the problems such as pest resistance to insecticide, killed natural enemies and environmental pollution for chemical pesticide control codling moth, provide a kind of preparation technology easy, extend effective drug duration, implement convenient, selectivity is strong, pollution-free and do not injure the liposome embedded technique of pheromones of natural enemy.
The technical scheme of the liposome embedded process using of a kind of oriental fruit moth pheromones of the present invention is: using lecithin, starch Sodium Octenyl Succinate as lipid body wall material, wall material ratio is lecithin: starch Sodium Octenyl Succinate=1～3: 4～5, core and wall material ratio are sex pheromone of Grapholitha molesta: wall material=1～2: 10, homogenization pressure 30MPa, liposome spraying condition is intake 500L/h, charging rate 270mL/h, EAT: 150 DEG C.
The invention has the beneficial effects as follows, preparation technology is easy, wall material is easily obtained and is nontoxic, effectively kill oriental fruit moth, there is thing pesticide resistance, the feature such as single-minded, efficient, free from environmental pollution, reduce the rate of release of sex pheromone of Grapholitha molesta, extended the sex pheromone of Grapholitha molesta drug effect lasting period.
