| 【目的】明确胡瓜钝绥螨Amblyseius cucumeris Oudemans以茶黄蓟马Scirtothrips dorsalis Hood为食物的生长发育和繁殖情况,获得其种群增长参数,为利用胡瓜钝绥螨防治茶黄蓟马提供参考依据。【方法】采用传统的生物学观察方法,在室内观测以茶黄蓟马为食物的胡瓜钝绥螨的各虫态发育历期、存活率、成虫寿命和产卵量,并组建实验种群生命表,分析种群生命表参数。【结果】胡瓜钝绥螨雌成螨对茶黄蓟马的取食量最大,可达122头,其次为若螨,幼螨不取食；以茶黄蓟马为食物的胡瓜钝绥螨世代发育历期为9.98d,存活率为94%；雌成螨平均寿命为24d,平均单雌产卵量为28粒,成虫的大量死亡出现在产卵高峰之后。胡瓜钝绥螨的净增殖力为26.95,内禀增长率为0.15,世代平均周期为22.32d,周限增长率为1.16,种群倍增所需时间为4.70d。【结论】以茶黄蓟马为猎物,胡瓜钝绥螨可完成其世代生长发育和繁殖,可作为茶黄蓟马的捕食性天敌进行其生物防治。 |

| 【Objective】To clarify the growth, development and propagation of Amblyseius cucumeris Oudemans with Scirtothrips dorsalis Hood as prey, the population parameters were obtained, which provided reference for the control of S. dorsalis by using A. cucumeris. 【Method】 The development duration, survival rate, adult longevity and fecundity of A. cucumeris with S. dorsalis as prey were observed indoors by using the traditional biological observation method, and the life table of the laboratory population was established, and the life table parameters were analyzed. 【Result】 The results showed that the feeding amount of female adult was the largest, up to 122 individuals, follow by nymph and non-feeding of larvae. The development period of A. cucumeris with S. dorsalis as prey was 9.98d, and the survival rate was 94%. The longevity of adult female was 24d, and the average per female oviposition was 28, and a large number of adult deaths occurred after the peak of oviposition. The net reproductive rate (R<sub>o</sub>), intrisic rate of natural increase (r<sub>m</sub>), mean generation time (T), finite rate of Increase (λ) and population increase double times (t) of A. cucumeris were 26.95, 0.15, 22.32d, 1.16 and 4.70d, respectively. 【Conclusion】 A. cucumeris can complete its generation growth, development and reproduction with S. dorsalis as prey, and can be used as a predatory enemy of S. dorsalis for its biological control. |
