摘  要：
【目的】明确斯氏钝绥螨在不同温度下对西花蓟马的捕食功能反应,为西花蓟马的生物防治提供理论依据。【方法】室内采用水琼脂培养基法,研究斯氏钝绥螨对西花蓟马的捕食功能反应。【结果】斯氏钝绥螨第一若螨对西花蓟马1龄若虫的日均捕食量随温度的升高而逐渐增加,而第二若螨、雄成螨和雌成螨的日均捕食量随温度的上升呈先增加后减少的趋势。斯氏钝绥螨雌成螨对西花蓟马1龄若虫的功能反应符合Holling-Ⅱ模型,在30℃时捕食效能达到最大,为18.146。在一定密度的西花蓟马环境下,斯氏钝绥螨雌成螨对西花蓟马1龄若虫的搜寻效应随着温度的上升而增加; 35℃时,搜寻效应下降。在西花蓟马1龄若虫的密度为30头时,斯氏钝绥螨雌成螨自身密度对西花蓟马1龄若虫的捕食具有明显的干扰作用。斯氏钝绥螨雌成螨捕食西花蓟马1龄若虫所产生的竞争属于分摊竞争。【结论】斯氏钝绥螨对西花蓟马有较好的捕食能力,其捕食功能反应符合Holling-Ⅱ模型,斯氏钝绥螨可用于西花蓟马的生物防治中。

摘  要：
【Aim】To provide a basis for biological control of the Western flower thrips,Frankliniella occidentalis,the functional response of the predatory mite,Amblyseius swirskii on F. occidentalis as prey was studied under different temperatures. 【Method】The predation of A. swirskii to F. occidentalis was studied by water agar in laboratory.【Result】The mean daily consumption of 1st instar of F. occidentalis protonymph increased with the increase in temperature,but decreased when the prey was deutonymph,adult male and female. The functional response of A. swirskii female adult mites on 1st instar of F. occidentalis could be described with HollingII equation,and the maximum feeding amount was 18.146 prey items/day at 30 ℃. At the same prey density,searching rate of A.swirskii female adult mites to 1st instar of F. occidentalis increased with the increase of temperature; but decreased at 35 ℃. The intraspecific competition by A. swirskii adult females was scrambling competition.【Conclusion】A. swirskii had a good predation potential against F. occidentalis,and the species is a promising biological control agents of the Western flower thrips.
