摘要
红颈常室茧蜂Peristenus spretus Chen et van Achterberg是绿盲蝽Apolygus lucorum(Meyer-Dür)若虫的优势寄生蜂,已被用于果园、茶园和农田绿盲蝽的生物防治。为明确红颈常室茧蜂滞育诱导的最佳光温条件,本试验在室内条件下设定两个温度(15℃、19℃)和三个光周期12L:12D、10L:14D、8L:16D处理,测定在不同温度和光周期组合下红颈常室茧蜂滞育蛹形成情况。试验结果表明,温度和光周期共同作用于红颈常室茧蜂的发育历期和滞育诱导。不同光周期条件下该寄生蜂卵-幼虫发育历期无明显差异,但15℃下卵-幼虫的发育历期为30.40~33.60 d,19℃下缩短为18.80~19.40 d。15℃结合不同短光照诱导红颈常室茧蜂蛹的滞育率无显著差异;19℃下诱导蛹的滞育率随光照时长的增加而显著升高。光周期12L:12D对红颈常室茧蜂的滞育诱导效果较好,19℃时红颈常室茧蜂卵-幼虫期的发育时间更短。综上,光周期12L:12D和19℃的光温组合能显著缩短诱导进程、显著提升红颈常室茧蜂滞育率,是本试验该寄生蜂滞育蛹生产的最佳光温组合。上述结果为红颈常室茧蜂作为绿盲蝽寄生性天敌,实现规模化生产、延长货架期,并最终作为生物防治产品进行大面积推广应用提供了重要基础数据支撑。
Peristenus spretus Chen et van Achterberg is one of the dominant parasitoids of Apolygus lucorum(Meyer-Dür),and has been applicated for field biological control of A.lucorum in orchards,tea plantations and agricultural fields.In order to clarify the optimal photoperiod and temperature conditions for the diapause induction of P.spretus,two temperatures(15℃,19℃),compared with three photoperiods 12L:12D,10L:14D,8L:16D were set up under laboratory conditions in this experiment,and determined the diapausing pupae formation of P.spretus under the different combinations of temperatures and photoperiods.The results showed that temperature and photoperiod acted together in developmental period and induction of diapause in P.spretus.There was no significant difference in the developmental period under different photoperiodic conditions,and the developmental period of egg-larvae ranged from 30.40 to 33.60 d at 15℃,and was shortened to 18.80 to 19.40 d at 19℃.There was no significant difference in diapause rate induced by 15℃combined with different short light durations.The induced diapause rate increased significantly with the increasing in photoperiod(light duration)at 19℃.Photoperiod 12L:12D was more effective in the diapause induction in P.spretus.But at 19℃,the egg-larval developmental period of P.spretus inside A.lucorum nymphs was shorter.In conclusion,the combination of photoperiod 12L:12D and 19℃could induce the higher proportion of P.spretus to enter into diapause faster,which was the best condition for the production of diapause pupae of this parasitoid.The above results provide important basic data for the large-scale production,shelf-life extension and large-area application of P.spretus as a natural enemy for controlling A.lucorum.
