It is distributed worldwide like humans and winters in the living room of humans. Females are 2.5 mm long and males are smaller than females. The male has dark hind limbs, which can be distinguished from the female. The samara fly (Drosophila suzukii Matsumura) is also called as fruit fly of Linesless, the English name Spotted wing drosophila, as found in strawberry orchards in Sonchi county in 1916 at the earliest time, is different from the fruit fly of black abdomen, besides feeding on the fruit of the fruit which falls to the ground or is damaged, the ovipositor of female insects is in a hard saw tooth shape, eggs can be directly laid in fruits with softer pericarps which are mature or are about to mature, and larvae feed on the fruits.
At present, in the field of fruit tree planting, the damage of fruit flies such as fruit trees including strawberries, blackberries, cherries, strawberries, plums, peaches, grapes, figs, kiwi fruits and pears and the like in the cultivation process of stone fruits is not ignored. The fruit flies can spawn on fresh grapes, mechanical damage caused by spawning and fruit softening caused by feeding after hatching of larvae can cause rot of the grapes, breeding a large amount of microorganisms, and causing a large amount of spawning of the drosophila melanogaster, seriously affecting the yield and quality of the fruits and even causing absolute production. With the enhancement of environmental protection consciousness and comprehensive control consciousness, biological control by natural enemies is increasingly accepted and used. The mature larva parasitic wasp of drosophila-stropharia rugosa is a parasitic wasp with good parasitic effect, and has obvious control effect on the control of drosophila if a large amount of breeding and releasing are carried out. However, the domestic and foreign breeding of Drosophila parasitic wasps has technical obstacles, so that the parasitic wasps have high mortality rate, and no effective device for breeding a large amount of the parasitic wasps indoors is provided.
