地中海实蝇 Ceratitis capitata(Wiedemann) 意大利科学家发现一种细菌和地中海实蝇的共生现象。该细菌可随实蝇的繁殖而随代传递,并且是地中海实蝇幼虫生长所必需的。因而他们推测地中海实蝇的群体饲养(用于遗传防治)产量可能受到这种微生物的制约。荷兰的科学家正在探索利用遗传工程技术来生产单一雄虫后代,这样将赋予不育昆虫技术害虫防治体系更强劲的生命力。他们把这一遗传工程称为Genetic sex- Ceratitis capitata (Wiedemann) Italian scientists have discovered a symbiotic relationship between bacteria and the fruit fly. The bacterium can be passed down from generation to generation with the fruit fly and is necessary for the growth of the Mediterranean fruit fly larvae. Thus they hypothesize that the production of the population (for genetic control) of Mediterranean fruit flies may be constrained by this microorganism. Dutch scientists are exploring the use of genetic engineering techniques to produce single male offspring, which will give sterile insect technology pest control system more robust vitality. They refer to this genetic project as Genetic sex-
