| Due to years of neglect in the prevention and control of insects in wenjiang airport,causing a large number of insects occur in wenjiang airport,attracting a large number of birds for food,which directly or indirectly affects flight safety and poses a great threat to human life safety.In order to reduce the activity of birds in the airport and reduce the impaction of birds,the species and number of insects in the range of chengdu wenjiang airport were systematically investigated and analyzed from April to November in 2016,and the drug control tests were carried out on the main insect beetles,cicadas and direct pteroptera insects in wenjiang airport.The main results are as follows:(1)there are 104 kinds of insects in the area of wenjiang airport and the surrounding area,with the dominant species of beetles and lepidoptera moths,among which the dominant species are the Chinese thorax beetle.The peak of insects in wenjiang airport is from mid-june to late July.(2)seven solar insecticidal lamps of different wavelengths were installed to trap the airport insects,and the results showed that the best effects on beetle larvae and lepidoptera insects were respectively 375 nm in wavelength and 405 nm in wavelength.(3)in the middle of June to early September,five different proportion formula of sweet and sour wine juice was carried out on the lawn insects,the results showed that the sugar vinegar liquor sugar which ratio is 3:1:3:10 traped and killed more pests,but the amount of insects induced by sweet and sour liquor is relatively small compared with the large number of insects at wenjiang airport,do not apply to the pest control at the wenjiang airport.(4)in April 2016,using the methods of spraying and spraying,five pesticides were evaluated on field efficacy evaluation of lawn grubs,the results showed that 5 % of chlorpyrifos granudes and 3% of octirophosphorous granuate were the best pesticides to protected against the grass grubs.The difference reached to the very significant levels with the other several differences,the preventive effect was 92.57% and 93.37% respectively.(5)in September 2016,the field efficacy evaluation of 5 pesticides against orthoptera insects was carried out by means of spray,and it showed that the protective efficacy of 4.5% highly effective cypermethrin emulsion was significantly higher than that of other agents in 1,3 and 7 days after the drug,showing a good quick effect and good durability.6)from June 21 to September 1,2016,the prevention and control tests of cicadas were carried out by using 5% of chlorpyrifos,40% of chlorpyrifos and 40% of the phosphorus suspension,by using the method of covering soil and binding sticky insect board to trunk.The results showed that the host plants of the cicada were willow,mulberry,camphor and loquat,among which willow was the main plant.Of the three insecticides used in the efficacy trials,40% of the insecticides were the best against cicadas,reaching 76.34%.(7)integrated a protective technology for pest control in combination with lamp lighting and drug control for wenjiang airport. |
