摘    要:为了探索古巴蝇防治甘蔗螟虫在广西蔗区应用的可行性,广西甘蔗研究所于2004~2005年从古巴引进古巴蝇并进行了相应研究.结果表明:古巴蝇能寄生二点螟、条螟、黄螟和玉米螟等甘蔗害虫.化蛹率为70%~90%,羽化率在80%~90%.不能寄生桑蚕.能用非自然寄主大蜡螟人工繁殖古巴蝇,平均化蛹率为100.46%,平均羽化率为86.32%.古巴蝇喜欢温暖潮湿,在26~28℃、相对湿度75%~85%时,生长发育最佳,生物学周期为25~40d.接种(寄生)至化蛹为8~10d,蛹期为6~10d,雄蝇寿命3~6d,雌蝇寿命20~30d.0℃以下的低温和42℃以上的高温对古巴蝇的生长发育、化蛹和羽化不利,古巴蝇蛹在8~10℃保存5~10d羽化率不受影响,但蛹期相应延长.本研究对指导广西蔗区应用古巴蝇防治甘蔗螟虫,促进广西蔗糖业可持续发展有着重要意义.

关 键 词:甘蔗螟虫  古巴蝇  生物学  生态学

Abstract:A strain of Lixophaga diatraeae Townsend imported from Cuba was assessed for its potential as a biological agent to control sugarcane borers by Guangxi Sugarcane Research Institute from 2004 to 2005. The results showed that: Cuban fly can parasitize some pests, such as Chilo infuscatellus Snellen, Proceras venosatum Walker, Tetramoera schistaceana Snellen and Ostrinia furnacalis Guenee etc., and the pupae rate was about 70% - 90%, the emergence rate was about 80% - 90%. Galleria mellonella can be used as an...
Keywords:Sugarcane borers  Cuban fly(Lixophaga diatraeae Townsend)  Biology  Ecology
