本研究在室内评价了在济宁采集的捕食性刘氏中剑水蚤单用及与球形芽孢杆菌(B.s.)或苏云金杆菌以色列变种(B.t.i.)合用对蚊幼虫的控制效果。在室内,刘氏中剑水蚤对白蚊伊蚊Ⅰ龄幼虫的捕食效果好于对中华按蚊和淡色库蚊幼虫的效果。蚊笼模拟试验表明,刘氏中剑水蚤可分别于9、10和7周内消灭淡色库蚊、中华按蚊和白蚊伊蚊的幼虫种群。该剑水蚤增长速率快,大量培养经济易行。现场试验证明,刘氏中剑水蚤虽可在蚊虫孳生地存活时间长于蚊虫季节,但单用该剑水蚤不能象化学杀虫剂一样快速完全地控制三种蚊虫。刘氏中剑水蚤与B.s.或B.t.i.合用,应用刘氏中剑水蚤的长持效和生物杀虫剂的速效,取得了高效、持久的防治效果。因此二者合用可用于蚊虫防治并可作为蚊虫综合防治的一个组成部分。
In this study, we evaluated the control of mosquito larvae in the predatory Liu collected in Jining indoors using either alone or in combination with B.subtilis (B.s.) or B. thuringiensis isolates (B.t.i.). In indoor, the predation effect of Sword Daphnia on the first-instar larvae of Aedes albopictus in Liu was better than that on larvae of Anopheles sinensis and Culex. Mosquito cage simulation tests showed that Cyclops can flee the larval population of Culex pipiens pallens, Anopheles sinensis and Aedes albopictus within 9, 10 and 7 weeks respectively. The Sword Daphnia growth rate, a large number of economic training. Field tests showed that although the Sword Daphnia in Liu could survive mosquito breeding longer than the mosquito season, the Scurva alone did not control the three mosquitoes as quickly and completely as chemical insecticides. Liu’s Sword Daphnia and B.s. or B.t.i. combined with Liu’s long-term use of water Daphnia and biopesticide quick-impact, and achieved effective and long-lasting control effect. Therefore, the combination of the two can be used for mosquito control and can be used as an integrated part of mosquito control.
