Leizhou Peninsula Fruit Fly Species Investigation And Control Test

Fruit fly belong to the Tephritidae, it is known as the Diptera no flap type of Tephritidae.There are about4000species all over the world, our country has more than400kinds. The host range of fruit flies are very wide, Fruit fly oviposit between the fruit peel and fleshjThe larvae feeding on the flesh.Causing fruit rot, fruit drop.Affects the yield and quality of fruit.The invasion of the fruit fly has had a serious impact on the agriculture of Leizhou Peninsula.The purpose of this study is to carry out a comprehensive prevention and control technology by monitoring the population dynamics of Leizhou Peninsula fruit fly, and provide a theoretical basis for population dynamics and control of fruit flies.The experiment was conducted in the Leizhou Peninsula, we conductde a long-term monitoring to the fruit fly population dynamics in Leizhou Peninsula with sex attractant Me, Cue.The Fruit flies in Leizhou Peninsula activities year-round,generation overlap, from March to April,the temperature began to rise, and the fly began breeding, The peak period of adult breeding from August to September. After September, the number of fruit flies gradually reducing.The Bactrocera dorsalis^Bactrocera cucurbitae and Bactrocera tauare the dominant species of fruit flies in Leizhou Peninsula.Besides,we analysis the trapp results with the different attractant on fruit fly;Set up different temperture to seek the influence on pupa;And test induced spawning by different host odor to analyze the tendency of Bactrocera dorsalis on host plants.In addition, we do the experiment of field control to seek comprehensive prevention and control measures,such as brown sugar bait method, fruit bagging method, Chemical control method and so on.comprehensive control system of science was established, which provides the theoretical basis for the sustainable development of effective control of fruit fly population, improve fruit quality, and the sustainable development of the agriculture.
