四川省攀枝花市烟区烟田金龟子种群动态初步研究

Preliminary Studies on Scarab Population Dynamics in Panzhihua Tobacco

笔者于2013-2014年采取挖查和灯诱法系统调查了四川省攀枝花市烟区金龟子幼虫和成虫的种群动态。结果表明:攀枝花市烟区为害烤烟烟叶的金龟子种类有24种,其中,暗黑鳃金龟和铜绿鳃金龟为优势种群;金龟子成虫在烟田5月下旬初见,6月中旬盛发,6月下旬达发生高峰,同时,成虫出土具有单日少、双日多的"隔日出土"习性;金龟子卵在烟田6月下旬初见,7月中旬为卵盛期,7月下旬达产卵高峰期;金龟子幼虫于7月中旬初见,7月下旬至8月中旬为卵孵盛期,8月上旬为3龄幼虫高峰期。

During 2013 to 2014, writer investigated the population dynamics of scarabs including larva and adults through digging and light temptation on the tobacco area of Panzhihua city at Sichuan province. The study approves： there are total 24 scarabs which would damage to- bacon on Panzhihua area. Among those, The dominant population are Holotrichia parallela and Anomala eoppulenta. Scarab adults begin to take shape on the end of may, begin to blooming on the middle of June and approach the peak time on the end of June. The study also indl- eatoc that scarab adults normally born on the even day but only few bern on the odd day. Scarab eggs begin to take shape on the end of June, blooming on the middle of July and approach the peak time on the end of July. Scarab larva begin to take shape on the middle of July, blooming during the end of July to the beginning of august and approach to the peak time on the middle of August.
