Abstract

The invention discloses artificial synthesized sex pheromone and lure of conopomorpha sinensis. The artificial synthesized sex pheromone and lure of the conopomorpha sinens characterized by being prepared by the following steps: evenly mixing trans-4,6-cis-10-hexadecatriene acetate, trans-4-cis-6,10-hexadecatriene acetate, trans-4,6-cis-10-hexadecatrien-ol,trans-4-cis-6,10-hexadecatrien-ol and cetyl alcohol according to the weight ratio of 0.1-3:12-25:1-5:1-15:12-50; dissolving the mixture by solvents such as acetone and the like; taking 50-3000mg of the preparation and adding the preparation into the sustained release carrier made of natural rubber, synthetic rubber, polyethylene, polyvinyl chloride, paper materials, resin or adhesive materials. The sex pheromone and lure provided by the invention have the positive effects: the sex pheromone and lure are applied to the prevention and detection of the conopomorpha sinensis, so that the attractive activity of the sex pheromone for the conopomorpha sinensis is greatly improved, high trapping success rate is high; and the artificial synthesized sex pheromone and lure are beneficial for increasing in benefits of industries and increasing in income of fruit farmers. Additionally, the sex pheromone and lure do not cause pesticide residues, so that the food safety cannot be influenced, the environment cannot be polluted and the ecological balance cannot be damaged, and the sex pheromone and lure are beneficial to promotion of sustainable development of the industries.

Description

A kind of lichee base of a fruit moth sex pheromone of synthetic and lure core

Technical field

The invention discloses a kind of insect sex pheromone and lure core, relate in particular to a kind of lichee base of a fruit moth sex pheromone of synthetic and lure core.

Background technology

Lichee base of a fruit moth (Conopomorpha sinensis Bradley) belongs to Lepidoptera, Gracilariidae, is the important pests of harm lichee and longan, is distributed widely in Southeast Asia and ground such as China Guangdong, Guangxi, Hainan, Fujian, Hong Kong and Taiwan.Larva can be bored moth harm lichee or longan, at young fruit expanding stage moth food fruit stone, fructescence moth food base of fruit, cause fruit development slowly, shedding or wormy fruit, output reduces, quality reduces.In the season outside the phase of bearing fruit, larva also can be bored moth flower fringe, young sprout and tender leaf master pulse, causes arteries and veins brown stain in the blade, Hua Sui and young sprout top withered.The wormed fruit rate that general time lichee and longan receive this worm to bore moth harm reaches 10%～20%, can reach 60%-90% when serious, causes than large economy to production and loses.Tradition control lichee base of a fruit moth mainly adopts chemical pesticide to prevent and treat; But because the maximum characteristics of lichee base of a fruit moth harm are directly to pierce host inside after the larva hatching; Therefore control efficiency is undesirable; And the use chemical pesticide, can cause not only that fruit farming residually exceeds standard, contaminated environment, the destruction ecological balance, also can cause the generation of pest resistance to insecticide.Compare with the traditional chemical method of preventing and treating; The biological control technology such as natural enemy insect, biogenic pesticide, pheromones of using have lot of advantages; Toxic and side effect is little, to the person poultry safety, environmentally friendly, insect is had the long term inhibition effect, be current and development in future trend.In present biological control technology; Microbial pesticide commercial processes such as AVM are quite ripe, and this medicament is high to lichee base of a fruit moth preventive effect, cost is low, easy to use, welcome by the peasant; But, there is food-safety problem because toxic side effect, the longevity of residure are long; Botanical pesticides such as nimbin also have certain use scale, but because cost is higher, and range of goods is less, the scope of application is restricted; China aculea fleahopper is a kind of predator insect that the prospect utilized is arranged; The ovum of on lichee and longan treetop, preying on lichee base of a fruit moth this worm of lichee base of a fruit moth egg-laying period release is effective " controlling worm with a worm " bio-control method; But still the research of aspects such as numerous and field release tech is expanded in the manual work that needs to strengthen Chinese aculea fleahopper, and solves the technological problems that Chinese aculea fleahopper batch production is produced; Parasite can be protected and utilize through agricultural measures, and then difficulty is bigger but will and discharge through artificial feeding, and the parasitic rate of field parasitic wasp is lower, and this also can't solve at short notice.Utilizing plant information element or insect sex pheromone pest control is a new way of biological control.In plant-feed insect identification host plant process, the volatile information compound that host plant discharges plays important communication guiding function.Lichee base of a fruit moth has certain rules property to the selection at host plant kind, organ and the position of laying eggs; Female worm is better than osmanthus flavor, bosom branch and 3 lichee kinds of glutinous rice wrapped in lotus leaves to the taxis of laying eggs that the imperial concubine laughs at fruit; Up and down the 2 parts ovum that falls is more at pericarp for same litchi fruits, and pulp is gone up with nuclear does not have the ovum amount of falling.This is because this worm is mainly confirmed host's kind and position through host's smell, thereby selects the righttest position of laying eggs.Therefore, can utilize host plant or non-host plant volatile information compound to lure or disturb the behavior of laying eggs of lichee base of a fruit moth to prevent and treat purpose to reach.The sex pheromone that utilizes insect to insect trap, isotropic, disturb mating etc., also can reach and prevent and treat purpose.Huang Zhensheng etc. utilize the synthetic gyplure of 5 kinds of sex pheromones that extracts from the thin moth of lichee cocoa (Conopomorpha cramerella SneIlen); Lichee base of a fruit moth male worm there is attractant effect; Can disturb the normal mating behavior of lichee base of a fruit moth, lure the lasting period to reach 3 months in the orchard.Feng Li etc. utilize the lichee base of a fruit moth gyplure of synthetic also can trap adult, but trapping quantity is lower, and its attractive activity has much room for improvement.So far, the pheromones activity that can synthesize is all also not high, can not obviously reduce the population quantity of lichee base of a fruit moth, needs badly prior art is improved.

Summary of the invention

The purpose of this invention is to provide a kind of lichee base of a fruit moth sex pheromone of synthetic and lure core, improve attractive activity and trapping success rate lichee base of a fruit moth.

For solving the problems of the technologies described above; The present invention realizes through following technical scheme: adopt instead-4, and 6-is suitable-and 10-16 carbon triolefin acetic acid esters, anti--4-are suitable-6,10-16 carbon triolefin acetic acid esters, anti--4; 6-is suitable-10-16 carbon three enols, anti--4-suitable-6; 10-16 carbon three enols, positive hexadecanol mix according to parts by weight ratio 0.1～3:12～25:1～5:1～15:12～50, with the dissolving of acetone equal solvent, promptly make lichee base of a fruit moth sex pheromone.Further, get described lichee base of a fruit moth sex pheromone 50～3000 micrograms, add in the slow-released carrier, promptly make lichee base of a fruit moth sex pheromone and lure core.Preferably, slow-released carrier is selected can be slowly, the slow-release material of release property pheromones equably, comprises natural rubber, synthetic rubber, polyethylene, polyvinyl chloride, paper material, resin or viscose material.To lure core and trapper to be used, promptly can be used for traping lichee base of a fruit moth.

Good effect of the present invention is: be applied to the control of lichee base of a fruit moth damage by disease and insect and observe and predict; Improve the attractive activity of sex pheromone to lichee base of a fruit moth greatly, the trapping success rate is high, helps industry synergy, the orchard worker increases income; And can not exist agricultural ghost to ring food security; Free from environmental pollution, do not destroy the ecological balance, help promoting the sustainable development of industry.
