Examine Of Effect Domesticate And The Elementary Observation Of The Antenna Sensilla Of Scleroderma Sichuanensis Xiao

Scleroderma sichuanensis Xiao, since to the discovery through many year artificial breeding system research, the line has already become a set of complete man-power numerous bee flow, realized under the existing condition has yearly produced 50,000,000 ability construction goal (Zhou Zuji 1999). And through the massive open country preventing and controlling work, provesScleroderma sichuanensis Xiao is the control Callidium villosulum Fairmaire,Semanotus sinoauster Gressitt,Clytus validus Fairmaire and so on the fine natural enemy, has the important development use value in the farming and forestry biological controls.But, each kind of natural enemy may prevent and control the harmful insect type is limited, moreover, artificial may supply reproduction natural enemy the type to be also limited, this has limited the artificial propagation natural enemy's widespread utilization. Scleroderma sichuanensis Xiao reproduces which with the substitution host to prevent and control the Callidium villosulum Fairmaire and Semanotus sinoauster Gressitt's effect reduces gradually along with the numerous Scleroderma sichuanensis Xiao generation's increase; Prevents and controls other non-primary hosts when long-homed beetle, because often search host ability not also can cause the preventing and controlling effect really ideally not. Scleroderma sichuanensis Xiao's in biological preventing and controlling application scope, may through carry on the oriented training to the known natural enemy, thus expands its application scope.This experimental basis Scleroderma sichuanensis Xiao study behavior the research, used the Monochamus alternatus Hope and its survival environmental information Scleroderma sichuanensis Xiao to carry on many generation of domestications. And through the room in domesticated record, between the Y sense of smell meter examination, the antenna ultrastructure observation as well as the forest puts the Scleroderma sichuanensis Xiao experiment.We may see, only uses the masson pine volatility smell to Scleroderma sichuanensis Xiao's many generation of domestications, enhanced Scleroderma sichuanensis Xiao on the masson pine to the Monochamus alternatus Hope's attack capability, but its attack capability has not enhanced along with the degree of domesticated increase. But Scleroderma sichuanensis Xiao with the Monochamus alternatus Hope in the masson pine bottom board to Scleroderma sichuanensis Xiao's domestication then enormous enhancement Scleroderma sichuanensis Xiao to the Monochamus alternatus Hope's attack capability, in the room to the Monochamus alternatus Hope from the domestication before 11.67%, has not enhanced to domesticates 3 generation of after 85.83% Scleroderma sichuanensis Xiao's antenna with Monochamus alternatus Hope domestication ALS and PS has had the corresponding change. Scleroderma sichuanensis Xiao to the Monochamus alternatus Hope's search and the parasitic ability enhancement, its ALS and PS and two kind of new feelings appeared the orderly change in quantity, Scleroderma sichuanensis Xiao domestication degree as well as to the Monochamus alternatus Hope's search and the parasitic ability enhancement, the ALS and PS reduces gradually, but two kind of new feelings increases gradually in their original position in quantity.Meanwhile, finally uses the propagate Scleroderma sichuanensis Xiao's substitution host and at this experiment domesticates 3 generation of Scleroderma sichuanensis Xiao with the Monochamus alternatus Hope in the masson pine bottom board, has carried on the degenerated experiment, proves the Scleroderma sichuanensis Xiao along with the degree of degenerated increase, to the Monochamus alternatus Hope's search ability, reduces greatly, but still was higher than to the Scleroderma sichuanensis Xiao without domesticated.But in to degenerates each generation of Scleroderma sichuanensis Xiao 's antenna to carry on the ultrastructure observation, discovered Scleroderma sichuanensis Xiao along to the Monochamus alternatus Hope's search and parasitic ability depression, its ALS and PS and two kind of new feelings also appeared the orderly change in quantity, Scleroderma sichuanensis Xiao along with degree of degeneration enhancement as well as to the Monochamus alternatus Hope's search and parasitic ability depression, two kind of new feeling quantities reduce gradually, but in their original position the ALS and PS quantity increases gradually, with domestication when just right opposite.
