摘　　要：1989～1995年在甘肃省夏河县对宽须蚁蝗的生活史、生活习性以及发生与环境的关系进行了研究。结果表明,该虫1年发生1代,以卵在土中越冬。翌年4月中旬末至下旬当平均气温达5.4℃左右时开始孵化出土,5月上旬末至下旬为孵化出土盛期。6月中旬始见成虫,7月上旬开始交配产卵,7月中旬至下旬为产卵盛期。整个蝗蝻期雄性平均为70d,雌性平均为75d左右,成虫寿命平均为49.5d。取食量随龄期增大而增大,蝗蝻期平均食量为333.15mg,成虫期平均食量为959.57mg。应用历年5月上中旬5cm平均土温,建立了发生高峰期的预测模型。此外,还根据历年4月中旬5cm平均土温和5月上旬降水量,建立了发生量的预测模型。In 1989 - 1995, the life history, seasonal population dynamics and behavior of Myrmeleotettix palpalis (Zubovsky), one of the main grasshopper pests in early season of grasslands in north China, and the relationship between its occurrence and environmental factors were studied in Xiahe County, Gansu Province. Two regression equations for forecasting the peak occurrence period and amount of this grasshopper decided by 5 cm soil temperature in early-middle May and 5 cm soil temperature in middle April as well as precipitation in early May, respectively, were developed.
