摘　　要：１９８９～１９９５年在甘肃省夏河县对红翅皱膝蝗和鼓翅皱膝蝗的生物学特性以及发生与环境的关系进行了系统的研究。两种皱膝蝗１年均发生１代，以卵在土中越冬。翌年５月中旬当平均气温达６．５℃左右时开始孵化出土，６月上旬至中旬为孵化出土盛期，７月上旬始见成虫，７月下旬或８月上旬开始产卵。红翅皱膝蝗若虫期平均约为６８ｄ，成虫寿命平均为４７ｄ左右，平均每雌产卵２５．７枚。鼓翅皱膝蝗蝗蝻期约为７２ｄ，成虫寿命５４ｄ左右，平均每雌产卵３２．６枚。红翅皱膝蝗的取食量随龄期增大而增大，蝗蝻期平均食量为１．６２ｇ左右，成虫期约为５．２０ｇ。应用历年６月上旬５ｃｍ土温建立了发生高峰期的预测模型。The biological and ecological factors affecting the occurrence of Angaracris rhodopa and A. baradensis were studied in Xiahe county, Gansu province, in 1989～1995. It was shown that the locust species had only one generation in a year, their eggs wintered in the soil and began to hatch in the middle of May when the average temperature reached around 6.5 ℃, with the hatching peak taking place in the first 20 days of June. The early hatched nymphs became adults in early July and started laying in late July or early August. The development of A. rhodopa nymphs took about 68 days and the adults lived for about 47 days with 25.7 eggs laid per female, as for A. baradensis the corresponding figures were 72 and 54 days and 32.6 eggs. The daily food intake for A. rhodopa was observed as 1.62 g per head for nymph and 5.2 g for adult. A linear regression model was established for predicting the occurrence of the pests.
