柑橘大实蝇生物、生态学及辐照不育技术最新研究进展

摘要

柑橘大实蝇是柑橘类果树的一种重要害虫，近几年在我国柑橘种植区的危害呈上升趋势，给柑橘产业造成了巨大损失。本文概述了环境因素包括温度、光周期、营养状况(饥渴)以及水淹对柑橘大实蝇生物学特性和成虫行为的影响，柑橘大实蝇成虫和幼虫人工饲养技术参数，柑橘大实蝇蛹滞育机制，辐照不育关键技术包括最佳辐照剂量和辐照时期，及其在湖北柑橘园柑橘大实蝇防控中的应用与示范情况等，并指出了尚需进一步开展的研究内容。%Bactrocera minax ( Enderlein) , the Chinese citrus fruit fly, is one of the most important citrus pests in southern China. In recent years, the damage caused by this species on citrus plants has increased, causing the citrus industry suffer a great loss. In this paper, knowledge on the effects of environmental factors, including temperature, photoperiod, as well as adult nutrition ( hunger, thirst) and tolerance to flooding in mature larvae, and on adult behavior of B. minax are evaluated. The parameters of artificial diet for mass rearing of B. minax adults and larvae, as well as the diapausing mechanisms of B. minax pupa is now clarified. The key techniques for IST ( irradiation sterile technique) , including the optimal irradiation dose of the 60 Co-γray and the optimal develop-ment status of irradiated B. minax pupa were clarified, leading to the first successful attempt to use IST to control B. minax in an or-ange orchard in Hubei Province. Finally, a proposal for further research on the sustainable management of B. minax is proposed.
