目的观察Boo2对光滑双脐螺的直接作用，及与氯硝柳胺合用的增效作用。方法采用25℃室内浸泡48h法。结果用1．563mg/LBoo2溶液浸泡8h，光滑双脐螺软体麻痹率为53．3％；36h麻痹率为100％。Boo2浸泡48h，LC50为3．676mg／L。与氯硝柳胺组成混合液，在Boo2浓度为3．125mg/L溶液中，氯硝柳胺的LC50由单独浸杀的0．096mg/L降至0．046mg/L，杀螺效果提高2．1倍。结论Boo2对光滑双脐螺有明显麻痹与杀灭作用，与氯硝柳胺复方用药有显著杀螺增效作用。

Aim To observe the molluscicidal effect of Boo2 [O,O′-diethyl-O″-(substituted phenylgly oxylonitrile oximino) thiophosphate] and synergism of Boo2 combined with niclosamide against Biomphalaria glabrata. Method Immersing method under 25℃ for 48 h in laboratory. Results The benumbed rate of snails immersed in 1. 563 mg/L of Boo2 solution for 8 h was 53.3％, and reached 100％ for 36 h. The LC50 of Boo2 was 3. 676 mg/L when the snails were immersed for 48 h. The LC50 of single niclosamide was 0. 096 mg/L but it decreased to 0. 046 mg/L when niclosamide combined with 3. 125 mg/L of Boo2 which showed that the molluscicidal effect raised by 2.1 times. Conclusion Boo2 has not only benumbing and molluscicidal effect to Biomphalaria glabrata but significant synergism when it combined with niclosamide to control the snails.
