摘要
在４种温度、２种相对湿度的不同组合条件下，研究了温湿度对苜蓿盲蝽发育、存活和繁殖的影响。组建了生命表，并对各生命参数进行了比较。在３０℃、８０％ＲＨ条件下，种群的内禀增长率最大（ｒ＿ｍ＝０．０６７１８），相应的增殖率极限λ＝１．０６９５／ｄ，平均世代周期Ｔ＝３２．０３１３ｄ，净生殖率Ｒ＿０＝８．６０１１。在试验的温度范围内，温度与内禀增长率之间呈抛物线趋势。
he present paper deals with the effects of temperature and relative humidity on thedevelopment, survival and reproduction of A. lineolatus at four different temperatures(20℃,25℃ ,30℃,and 35℃)and two relative humidities(60%and 80%RH).The life tables wereconstruc-ted and life parametrers were compared at 8 treatments. At 30℃ and 80%RH the intrinsicrate of natural increase was the highest(r_m=0.06718)and the finite rate of increase(λ)wasdetermined to be 1.0695/d. The mean generation time(T)was calculated to be 32.0313 daysand the net reproductive rate(R_0)to be 8.6011.The relationship between the temperaturesand the intrinsic rates of natural increase showed a parabolic curve within the temperaturerange tested.
