Description
Technical field
The present invention relates to a kind of microcapsule embedded technology field of sex pheromone of Grapholitha molesta, by using microcapsules
Sex pheromone is embedded, extension sex pheromone of Grapholitha molesta efficacy time is reached, strengthens the mesh disturbed that mated to oriental fruit months
's.
Background technology
Oriental fruit months is the primary pest for endangering pears, peach and apricot.In recent years, oriental fruit months turns into many fruits of China
The normal hair important pests in area, seriously endanger fruit tree, and Disaster Area is increasing, there is the trend aggravated year by year.
The preventing and treating to oriental fruit months depends on chemical pesticide at present, but the worm has brill moth habit, once larva
Eat into tender tip or fruit, chemical pesticide cannot play good effect, at the same time, chemical prevention causes the anti-medicine of insect
Property, killing natural enemy and the problems such as environmental pollution.Which increase the difficulty of preventing and treating oriental fruit months.
The research of insect sex pheromone is research emphasis both domestic and external with application.Handed over using insect sex pheromone interference insect
With the control of insect for being widely used in large area.At present be usually used in Insect pest suppression preventing and treating formulation have hollow fibre, plastic sandwich,
Natural rubber core and microcapsules etc..Wherein microcapsules are ideal formulations, because prepared by insect sex pheromone microcapsules
Technique is easy, and active component is closed in cyst wall, limits the diffusion of sex pheromone, isolation illumination, air and moisture, reduction
The speed that active component is oxidized and decomposed, can control constant to discharge and kept for longer action time；Simultaneity information
Plain microcapsules can be administered using traditional spraying equipment, and this reduces manually put into and add regulation and control delivery rate
With the flexibility of number of times.
Therefore, the microcapsule embedded technique of non-environmental pollution control sex pheromone of carpocapsa pomonella is explored imperative.
The content of the invention
The invention reside in cause pest resistance to insecticide, killing natural enemy and environmental pollution etc. for chemical pesticide control carpocapsa pononella
Problem is there is provided a kind of preparation technology simplicity, extension efficacy time, easy to implement, selectivity is strong, pollution-free and does not injure natural enemy
The microcapsule embedded technique of pheromones.
The technical scheme that a kind of microcapsule embedded technique of sex pheromone of Grapholitha molesta of the present invention is used is：With Arab
Glue, maltodextrin, starch Sodium Octenyl Succinate are Arabic gum: maltodextrin as microcapsule wall material, compound wall materialses ratio:
Starch Sodium Octenyl Succinate=1: 3: 5, core and wall material ratio are sex pheromone of Grapholitha molesta: wall material=1: 10, tween
20th, Tween 80 is compound emulsifying agent, and emulsifying agent and core ratio are compound emulsifying agent: core=1: 10, homogenization pressure 20Mpa.
Microcapsules spray drying condition is：Intake 700L/h, charging rate 360mL/h, EAT：170℃.
A kind of microcapsule embedded technique of sex pheromone of Grapholitha molesta of the present invention, microcapsule embedded rate 93.2%, raw material is returned
Yield：82%.Microscapsule powder core and wall material ratio are released always respectively for 1: 10 sample in 28 DEG C, 50 DEG C and field temperature
39.4%, 46.3%, the 40.9% of amount.A kind of liposome embedded technique powder embedding rate of oriental fruit months pheromones of the present invention
96.69%.Liposome powder core and wall material ratio release total amount respectively for 1: 10 sample in 28 DEG C, 50 DEG C and field temperature
31.7%, 40.3%, 31.8%.
A kind of microcapsule embedded technique of sex pheromone of Grapholitha molesta of the present invention, preparation technology is simple, and wall material is nontoxic,
And easily obtain, oriental fruit months can be effectively killed, interference oriental fruit months mating effectively reduces its insect density, simultaneously
With it is single-minded, efficient, free from environmental pollution the features such as, reduce the rate of release of sex pheromone of Grapholitha molesta, extend pears small
The heart-eating worm sex pheromone drug effect lasting period.
