摘　　要：[目的]研究古巴蝇人工繁殖技术及其对二点螟的寄生能力。[方法]通过人工接种试验,研究了不同蝇蛆与大蜡螟幼虫接种比例对古巴蝇生长发育的影响;通过室内低温储藏试验,研究了低温对古巴蝇蛹羽化率的影响;通过室内、田间比较试验,研究了不同生态条件(湿度、阳光)对古巴蝇蛹羽化率的影响以及古巴蝇对二点螟的寄生能力。[结果]蝇蛆与大蜡螟幼虫的最佳接种比例为3∶1和4∶1,古巴蝇产蛹量分别为279和327头;10℃条件下进行短期贮藏对古巴蝇蛹的羽化率影响较小,但贮藏时间不宜超过15 d;室内、田间寄生试验结果表明,古巴蝇对二点螟的寄生能力较强,寄生率达33.3%～50.0%;在甘蔗拔节期和成熟期寄生率分别为47.8%和41.7%,苗期几乎不能寄生。[结论]该研究结果为人工大规模繁殖古巴蝇及其田间释放技术提供了科学依据。[Objective]The artificial breeding technology of Cuban fly（Lixophaga diatraeae）and its parasitic ability on Chilo infuscatellus was studied.[Method]Though artificial inoculation experiment,the effects of different inoculation ratios between maggot and wax moth larvae on the growth and development of Cuban fly were studied.Through indoor low temperature storage tests,effects of different temperatures on the emergence rate of Cuban fly were studied.The effects of different ecological conditions（humidity,sunshine） on the emergence rate of Cuban fly and its parasitic ability on Chilo infuscatellus were studied through indoor and field comparison experiment.[Result]The optimum inoculation ratios between maggot and wax moth larvae were 3∶1 and 4∶1,pupa production amount were 279 and 327 respectively;short storage under the temperature of 10 ℃ had little effect on the emergence rate of Cuban fly,while the storage time should not exceed 15 d,Indoor and field parasitic test showed that Cuban fly had strong parasitic ability on C.infuscatellus,the parasitic rate reached 33.3%-50.0%;the parasitic rate during elongation stage and maturity stage were 47.8% and 41.7% respectively,while they almost could not parasite during seedling stage.[Conclusion]The results provided scientific basis for artificial breeding of Cuban fly in large scale and its field release technology.
