Description
Technical field:
The invention belongs to field of pest control, particularly relate to anti-Holotrichia parallela sex attractant of a kind of crops and preparation method thereof.
Background technology:
Interactional chemical substance between pheromones (pheromone) individuality of the same race, can affect behavior each other, habit and even grow and physiological activity.Pheromones is manufactured by body inner gland body, and directly discharge is dispersed into external, and pheromones relies on the conductive medium such as air, water to pass to other individualities.Pheromones is had from lower animal to higher mammal.Due to the outer environment transmission of pheromones, therefore also known as pheromone.Between biological xenogenesis, interactional chemical substance is called allomone or allomone.Allomone between insect has allomone, kairomone, semaphorins etc.Pheromones major sexual pheromones, aggregation pheromone, warning information element, trail, marking pheromone etc.
Pheromones is the general designation of the compound playing chemical communication effect between organism, is the chemical molecular language that insect exchanges.Comprise: kairomone, allomone, collaborative element, assembly pheromone, trail pheromone, warning information element, epideictic pheromone, sex pheromone.At occurring in nature, insect female adult pest is after sexual maturity, a kind of compound being sex pheromone can be discharged, it is released into after in air with Diffusion of gas stream, stimulate the chemical sensation organ in male worm feeler, cause male sexual drive and lure male worm to the flight of source of release orientation, and with the mating of release female adult pest to produce offspring.Therefore, insect sex attractant product is bionical high-tech product, by the sex pheromone luring core to discharge Prof. Du Yucang.
Insect pheromone be insect be used for representing assembles, look for food, mating, the various information such as warning compound, be the chemical molecular language of insect interchange.Wherein insect sex pheromone is the compound that regulation and control insect male and female attract behavior, not only sensitivity but also single-minded, and operating distance is far away, and temptation is strong.Gyplure is the insect sex pheromone of simulating nature circle, is discharged into by release the bionical high-tech product that different in nature insect is trapped and killed in field.This technology insect-killing trapping does not contact plant and agricultural product, does not have the sorrow of residue of pesticide, is one of prefered method of Modern agricultural ecological pest control.
Insect sex pheromone is as the chemical communication instrument of reproductive phase between different in nature insect of the same race, the high complexity of its chemical constitution and particularity are the important guarantees of reproduction isolation between insect kind, therefore, sex pheromone between different insects can not substitute mutually, also can not cause and obscure, this regionality insect is investigated, there is larger practical value in plant quarantine and mass trapping etc.
Patent 201210218955.5 discloses a kind of Against Conopomorpha sinensis Bradley sex pheromone of Prof. Du Yucang and lures core, it is characterized in that adopting trans-4, 6-cis-10-16 carbon triolefin acetic acid esters, trans-4-cis-6, 10-16 carbon triolefin acetic acid esters, trans-4, 6-cis-10-16 carbon three enol, trans-4-cis-6, 10-16 carbon three enol, positive hexadecanol mixes according to parts by weight ratio 0.1 ~ 3:12 ~ 25:1 ~ 5:1 ~ 15:12 ~ 50, dissolve with acetone equal solvent, getting dosage is 50 ~ 3000 micrograms, add by natural rubber, synthetic rubber, polyethylene, polyvinyl chloride, paper material, in the slow-released carrier that resin or viscose material etc. are made.Good effect of the present invention is: be applied to the control of Against Conopomorpha sinensis Bradley damage by disease and insect and observe and predict, greatly improve sex pheromone to the attractive activity of Against Conopomorpha sinensis Bradley, trapping success rate is high, be conducive to industry synergy, orchard worker increases income, and agriculture ghost sound food security can not be there is, free from environmental pollution, do not destroy the ecological balance, be conducive to the sustainable development of promotion industry.
