The Biology Peculiarity Of Trichogramma Spp Carrying Biology Pesticide And The Control Effect On Asian Corn Borer(Ostrinia Furnacalis)

Biology pesticide have the characters of safety, high effectiveness, long persistence and also can avoid the problems such as Resistance,Resurgence, Residue, caused by chemical control, but biology psetcide's cost is higher and the effectiveness is unstable . The other means of biology control is using parasitic insect belong to Hymenoptera -Trichogramma spp to autoeciousness the pests'eggs. The manipulation of the method is much simple and acceptable,but the control effect is weak and only can kill 60 perecents of the pest at best .The research want to improve control effect by the means of combing the two means of the biology controlAccording to the experiment using isotope to make trace for the transfer of the biology pesticide from the carrier to the drone pest; Comparing the temperature effect on the ability of autoeciouiness and the nature life of the Trichogramma carrying biological pesticide to that of the Trichogramme without any bacterial . Comparing the relative humidity effect on the ability of autoeciouiness and the nature life of the Trichogramma spp carrying biological pesticide to that of the Trichogramme without any bacterial Comparing the ability of autoeciouiness and control effect in simulated nature condition of Trichogramma carrying biological pesticide to that of Trichogramma spp without any biology pesticide ; Comparing the ability control effect in cornfield of Trichogramma spp carrying biological pesticide to that of Trichogramma spp without any biology pesticide ; menstruating and calculating the amount utility ingredient of the biology pesticide carrying by Trichogramma spp; menstruating virulence of different kinds of bacterial strands ; searching for proper mode of the combination of the Trichogramma and biology pesticide ; researching for the effective device for Trichogramma carrying biology pesticide I know that the transfer method is doable and benefit to us, and the biology pesticide is safe to its carriers .In July, Dendrolinus punctatus carrying several kinds of bacteria such as BT , Beauveria bassiana and others selected in the dead larva were put in JiLinAgriculture University's experimental corn field two times , in order to control the first generation of Ostrinia furnalis Guence .A month after , the control effect was investigated; the reduce amount of dead larva each hundred individual plant was investigated in September . The result improved the reduce amount of dead larva each hundred individual plant of Trichogramma carrying biology pesticide was 16.67%heigher than that of Trichogramma without biological pesticide .The carried biology pesticide can make the rate of the corn border increase 25.8%Researched on the four proper combine method, and then selected the best one . The case proved the utility amount of the ingredient of the biology pesticide carried by Trichogramma spp is large enough to kill the larva survived after the eggs parasited by Trichogramma spp. Using NE55 electrocircuit and other electrics principle, invent a new device made of ingredient such as the exit for Trichogramma spp , the kitchen of the electric resource , the electric resource which has 4.5 voltage of pressure , the fun that can cause the air current go up , capacitance that can adjust the electricity's density. The device can work regularly that it will go on working for a period of time and then relax for equal period of time and then go on working and then relaxing, the repetition will continual untill the electric resource is used up . Depending on 721 and 751 model spectrophotometer , we know a single Trichogramma spp can carry 107~ 10 spores which are utility ingredient of the biology pesticide.Seduced the Trichogramma spp carrying biology pesticide to move on pieces of eggs of Ostrinia furnalis Guence, and then kept the eggs with proper condition,and then fed the larva with artificial feedstuff after the eggs incubated , and then calculated the dead rate of the larva . Sprinkled 4ul liquor containing BT with different concentration from 10"3g/ml to 10'6g/ml on the eggs...
