A method of manufacturing hymenoptera-immune globulin is disclosed. In a presently preferred embodiment, the method involves the steps of concentrating a raw immune globulin solution; freezing the concentrated immune globulin solution; thawing the frozen concentrated immune globulin solution; adding sufficient mono or disaccharide to the thawed concentrated immune globulin solution to yield a solution of about 0.25 to about 0.35 osmolar; filtering the thawed concentrated immune globulin solution; and lyophilizing the concentrated immune globulin solution.

The invention relates to a push-pull technology for controlling pests through light. In the same biological system, pest expelling lamps are installed in a center area, and expel pests to move towards the edge of the system. Trap lamps are installed on the edge of the biological system, and the pests expelled to the edge of the biological system are trapped. The wavelength of the pest expelling lamps is suitable for repelling pests, and the wavelength of the trap lamps is suitable for trapping the pests. According to the push-pull technology, the pest expelling lamps and the trap lamps with different numbers are installed according to the size of the area of the biological system, the distance between the pest expelling lamps, the distance between the trap lamps and the distance between the pest expelling lamps and the trap lamps are 100-150 m, 150-250 m and 250-500 m respectively. For a large-area biological system, multiple rows of pest expelling lamps and trap lamps can be alternately installed. The wavelength of the pest expelling lamps is 500-600 nm, and the expelling performance on Lepidoptera moth pests is high; the wavelength of the trap lamps is 350-390 nm, and only moth pests can be expelled. The push-pull technology can be used for protecting natural enemy insects of coleopteran, hymenoptera, neuroptera and the like and some neutral insects.

The invention discloses a synergistic insecticidal composition containing thiamethoxam and tolfenpyrad and application thereof. The synergistic insecticidal composition comprises main effective components of thiamethoxam and synergistic in a weight ratio of 1-60:1-70. The insecticidal composition has expanded spectrum of control and synergistic effect, and can reduce the cost of medication, be formulated into missible oil, wettable powder, microemulsion, aqueous emulsion, suspending agent and water dispersible granule for the control of various insects of Lepidoptera, Hemiptera, Hymenoptera and Coleoptera.

The invention discloses a synergistic insecticidal composition containing Tolfenpyrad and alpha-cypermethrin and its application. The insecticidal composition takes Tolfenpyrad and alpha-cypermethrin as main effective components, wherein Tolfenpyrad and alpha-cypermethrin are in a weight ratio of 0.1-80:0.5-80. With control spectrum-expanding and synergistic effects, the insecticidal composition can reduce the drug cost, can be prepared into missible oil, wettable powder, microemulsions, emulsions in water, suspending agents as well as water dispersible granules, and can be used for controlling Lepidoptera, Homoptera, Hymenoptera, Coleoptera and other pests.

The invention belongs to the technical field of pesticide, particularly relates to an insecticide combination containing flucythrinate and dinotefuran, and belongs to an insecticide combination, and a preparation method and the application thereof. The insecticide combination has high insecticide efficiency, and effectively prevents and treats various insect pests, such as hemiptera, Lepidoptera, beetles, diptera, orthoptera, hymenoptera insect pests and the like, the prevention and treatment effects of the combination are obviously higher than that of flucythrinate or dinotefuran, the applied dosage of each active substance is greatly reduced, and the insecticide combination not only has ecological significance, but also has environmental protection significance.

The invention discloses a compound pesticidal composition containing tolfenpyrad and methoxyfenozide and application thereof. The pesticidal composition uses tolfenpyrad and methoxyfenozide as main effective components, wherein the weight ratio of the tolfenpyrad to the methoxyfenozide is (0.1-80):(0.5-80). The pesticidal composition can generate higher synergic effect, overcomes and postpones the drug resistance of pests, has the advantages of high pesticidal speed and long duration time, lowers the pesticide cost, and has obviously higher preventing and treating effects than a single agent. The pesticidal composition can be used for preventing and treating Lepidoptera, Hemiptera, Coleoptera, Hymenoptera, Diptera, Thysanoptera and acarid pests on crops, especially has specially good effect on preventing and treating cabbage moths, cotton bollworms and asparagus caterpillars in Lepidoptera, thrips in Thysanoptera, acarids and other pests, and has obviously higher effect than a single agent.
