The invention provides a method for preventing and curing irradiated sterility of Drosophila melanogaster. According to the living habits and genetic characteristics of Drosophila melanogaster, the invention designs a HFY YC gamma irradiation device for irradiation. The irradiation dose rate is 1 Gy/min and the irradiation dose is 90 120 GY. Under this condition, the pupa emergence rate is high, the deformity rate is low, the hatching rate of the offspring eggs is extremely low, and the activity is not affected. Influence. Compared with the prior art, the irradiation sterility control method provided by the present invention can make the male sterile, and the male successfully copulates with the female in the natural environment without producing offspring. At the same time, the activity and longevity of males were not affected. The method is pollution-free, resistant, durable, specific and safe to human, animal and natural enemies.

一种用于防治斑翅果蝇的辐照不育方法
本专利技术属于果蝇防治技术,具体涉及一种用于防治斑翅果蝇的辐照不育方法。
技术介绍
斑翅果蝇(DrosophilasuzukiiMatsumura,1931)属双翅目(Diptera)果蝇科(Drosophilidae)果蝇属(Drosophila)水果果蝇亚属(SubgenusSophophora),是一种危害草莓、蓝莓、树莓、黑莓、樱桃、葡萄和桃等软皮水果的全球性害虫。斑翅果蝇成虫体长2~3mm,翅展6~8mm,雌虫体长3.2~3.4mm,体色近黄褐色或红棕色。其成虫与其他果蝇区分的关键特征:(1)斑翅果蝇雄成虫双翅R1脉端部有一个明显黑斑,前足的第一、第二跗节均具性梳,梳齿3~6根;(2)斑翅果蝇雌成虫产卵器黑色、硬化,有光泽,外形巨大呈锯齿状,齿状突颜色较产卵器其他部位深,可刺入果皮并产卵。斑翅果蝇产卵器呈锯齿状,能够刺穿表皮,将卵产于完好的果实内,然后幼虫在果实内部取食危害,隐蔽性强,防治难度大。斑翅果蝇寄主范围广、繁殖速度快、传播迅速,对水果危害严重。不仅影响有关水果业的生产,还严重影响水果国际贸易的正常进行,造成严 ...
