Abstract

Functional response and predation rate of Amblyseius swirskii (Athias-Henriot) on eggs of Tetranychus urticae Koch were determined on strawberry under laboratory conditions (70 ± 10% R.H. and 16L:8D h) and three constant temperatures of 25, 30 and 35°C. The type of functional response was affected by temperature. Type III functional response was determined for adult female of A. swirskii at 25°C, whereas type II was observed at 30 and 35°C. The longest handling time ( T h ) (0.6 ± 0.005) was observed at 25°C and the shortest handling time (0.46 ± 0.003) and higher attack rate ( a ) (0.56 ± 0.054) were observed at 35°C. Handling time ( T h ) decreased from 25 to 35°C. Temperature had a significant effect on the daily and total predation rates of each different stages: the predation rate increased from larva to adult and with temperature from 25 to 35°C, and the maximal value being reached at 35°C. The maximal predation capacity of female was about 40 eggs per day per females at 35°C. The results of this study showed the effect of temperature on functional response and predation rate of A. swirskii .

三种恒温条件下威氏钝绥螨的功能反应及捕食率

在25℃、30℃、35℃3种恒温条件下(70±10% rh、16L:8D h)，测定了威氏弱绥螨(Athias-Henriot)对草莓叶螨卵的功能反应和捕食率。功能反应类型受温度的影响。25°C条件下，雌成虫的功能反应为III型，30°C和35°C条件下为II型。25°C处理时间最长(Th)(0.6±0.005)，35°C处理时间最短(0.46±0.003)，攻毒率(a)最高(0.56±0.054)。处理时间(T h)从25℃降至35℃。温度对各阶段的日捕食率和总捕食率均有显著影响，从幼虫到成虫，捕食率随温度的升高而升高，在温度为25 ~ 35℃时达到最大值。在35℃条件下，雌虫的最大捕食能力约为每天40个卵。研究结果表明温度对黄纹田鼠的功能反应和捕食率有影响。
