Research On Incentive Mechanism Of Mulberry To Apriona Germari

Moraceae plant is hose of complement the temperament of the nourishment to Apriona germari.The choice mechanism of Apriona germari to mulberry has great academic signality to breed fastness trees and father synthesisly to Apriona germari. The application gives or gets an electric shock physiology and livings to measure a method to research the incentive mechanism of moraceae plant to Apriona germari. The exploitation the senses of smell measurement instrument to measurese Apriona germari to a few kinds sense of smell reaction which sends main host plant(mulberry, Chinese white poplar, apple tree, willow, elm)firstly,then use the dynamic cresting air body circulation method collecting volatile from mulberry, make use of a TCT-GC/MS technique to authenticate its main chemistry composition and use scanning electron microscopy to scan the sensill on the antenna of Apriona germari .Lastly through standard sample of main chemistry composition in mulberry to Apriona germari carry on antenna electric potential reaction and the sense of smell behavior to respond a measurement.The result of research is as follows:1.The incentive proportion of mulberry and hair white poplar, apple, willow, elm to Apriona germari is 6.8:1.2,5.6:1.2,5.8:1.2,6.2:0.8.Confirming mulberry incentive function to Apriona germari biggest.2.The main chemistry composition of volatile from mulberry is 8 kinds, include cis-3-hexenal, 3-hexen-l-ol(c,t), cis-3-hexenyl acetate,nonanal,decanal,butanoic acid,3-hexenyiester and acrylic acid,2-ethylhexyl ester.Among them(agreeable) cis-3-Hexenyl Acetate is the tallest.3.Three types of sensill on the antenna of Apriona germari were found by scanning electron microscopy. It concludes styloconic sensillum,trichoid sensillum and cylindric sensillum. Make use of standard sample to stimulate the tip department, central department and basal department on antenna of Apriona germari , numeric value of antenna electric potential present a steps degree to descend, the tip department to have higher antenna electric potential among their activity, central is less, but the antenna electric potential of basal department is the least, explain antenna of Apriona germari to the volatile from mulberry sensitive part should for the tip department.4.Through 5 kind of densities of 3-hexen-l-ol,cis-3-hexenyl acetate.nonanal, decanal and acrylic acid,2-ethylhexyl ester 5 kinds of standard sample compoundcarry on the reaction result of the antenna electric potential enunciation to the tip department on antenna of Apriona germari, the antenna of Apriona germari to 3-hexen-l-ol (1/10), cis-3-hexenyl acetate (1/10) and parts of densities(original liquid) of the nonanal and decanal respond all very greatly, to acrylic acid,2-ethylhexyl ester and the parts of density of nonanal respond smaller.In the single body compound mix together with of the antenna electric potential the reaction, the 2nd(nonanal : cis-3-hexenyl acetate =2:7), 8(3-hexen-l-ol: nonanal: decanal : acrylic acid,2-ethylhexyl ester =1:2:2:1), 9(nonanal: decanal: acrylic acid,2-ethylhexyl ester: cis-3-hexenyl acetate =2:2:1:7), 10(3-hexen-l-ol : nonanal: decanal : cis-3-hexenyl acetate: acrylic acid,2-ethylhexyl ester =1:2:2:7:l)grow to mix a formulation type antenna of Apriona germari to stimulate more and greatly to the mulberry, among them the function of 3-hexen-l-ol and cis-3-hexenyl acetate is more.5. Reaction of antenna electric potential to the antenna of Apriona germari and its behavior which pass sense of smell reaction measurement to express greatly part of single body compounds respond substantially is consistent.The incentive function and avoiding function of a kind of chemical compounds is relative to Apriona germari,the different concentration of standard sample has different influence to Apriona germari. Nonanal(l/10), cis-3-hexenyl acetate(l/100), acrylic acid,2-ethylhexyl ester (1/10) have abvious lure function.The lure function of cis-3-hexenyl acetate(l/1000,l/10)and acrylic acid,2-ethylhexyl ester (1/100) is different extent. Decanal and 3-hexen-l-ol have abvious avoid function to Apriona germari. Through the result of research we-know cis-3-hexenyl acetate which is highest in volatile from mulberry has abvious incentive function to Apriona germari on low concentration.
