摘要
为探明拟环纹豹蛛与猎物间联系规律,以拟环纹豹蛛对猎物的选择正确率为指标,采用L_(16)(4~3)正交试验法研究温度(20℃、24℃、28℃、32℃)、距离(4、8、12、16 cm)、体液浓度(15%、30%、45%、60%)对拟环纹豹蛛捕食定位作用的影响。极差分析结果表明:各因素对拟环纹豹蛛选择猎物方向正确率的影响程度依次为:距离>温度>体液浓度。验证性试验证实对拟环纹豹蛛捕食定位最有利的因子组合为:距离为4 cm,温度为24℃,体液浓度为60%。该条件下,拟环纹豹蛛对猎物选择正确率为(79.76±3.60)%。
In order to clarify the relationships between Pardosa pseudoannulata and prey, the choice accuracy for the prey was used as the index, the effect of temperature （20℃, 24℃, 28℃, 32℃）, distance （4 cm, 8 cm, 12 cm, 16 cm） and concentration of prey fluids （15%, 30%, 45%, 60%） on Pardosa pseudoannulata locating the prey was studied through G6（43） orthogonal experiment. The range analysis results showed that the sequence of the choice accuracy caused by the factors was as follows： distance 〉temperature 〉concentration of prey fluids. The verification experiment confirmed that the optimal combination for choice accuracy was 4 cm distance, 24℃ and 60% prey fluids. Under this condition, the selection correct rate was （79.76±3.60）%.
