摘　　要：选用4种杀螺剂在水稻田与室内2种环境下开展药效试验,并评价了2种药剂对螃蟹的安全性。结果表明:在水稻田未保水的情况下,70%杀螺胺WP 600 g/hm^(2)、750 g/hm^(2),26%四聚·杀螺胺SC 1800 g/hm^(2)对福寿螺表现出良好的防效,药后7 d的防效分别为96.45%、97.17%、97.87%,同时对稻田福寿螺表现出较好的速效性。室内条件下,26%四聚·杀螺胺SC 1800 g/hm^(2)、6%四聚乙醛GR 9000 g/hm^(2)对福寿螺的防效良好,药后24 h的防效分别为100.00%、95.83%。室内条件下,四聚乙醛、杀螺胺对螃蟹敏感,安全性低。The efficacy tests were carried out in paddy field and indoor environment by four molluscicides,and the safeties of two molluscicides on crab was evaluated.The results showed that in the absence of water retention in rice fields,niclosamide 70%WP 600 g/hm^(2),750 g/hm^(2),and metaldehyde·niclosamide 26%SC 1800 g/hm^(2) had good control effects on Pomacea canaliculata.At the 7th day after treatment,the control effects were 96.45%,97.17%,and 97.87%,respectively.The above molluscicides showed good quick bioactivity against Pomacea canaliculata in rice fields.Under indoor conditions,metaldehyde·niclosamide 26%SC 1800 g/hm^(2) and metaldehyde 6%GR 9000 g/hm^(2) had good control effects on Pomacea canaliculata.The control effects were 100.00%and 95.83%at the 24th hour after treatment.Under indoor conditions,metaldehyde and niclosamide were sensitive and had poor safety to crabs.
