摘 要：
辣椒田蟋蟀有5种。北京油葫芦 Teleogryllus emma Ohmaehi et Matsumura 为陕西关中灌区椒田的主要种。大扁头蟋 Loxoblemmus doenitzi Stein 为不同生态区的常见种。各种蟋蟀在陕西1年均发生1代,以卵越冬,4月下旬孵化盛期,4月下旬—9月上旬若虫发生期,8月下旬—9月下旬成虫发生盛期。8—9月是为害辣椒的关键时期。蟋蟀具有较强的趋光性、趋化性,有趋向于渠边、地边的习性,18—19时为日活动高峰。地膜、杂草孳生、生长势郁闭、麦糠(草)覆盖及混作的椒田,种群数量大,为害严重。早期田间挖窝诱蛛、插种玉水、花生、繁育天敌,中期溜施毒土,后期毒饵诱杀,是控制蟋蟀为害的有效措施。
