氰戊菊酯、醚菊酯对日本囊对虾的急性毒性
Acute toxicity of Fenvalerate and Ethofenprox on Penaeus japonicus
摘要
Abstract
To study the acute toxic effects of two pyrethroid insecticides on Penaeus japonicus, the acute tox-icity of Fenvalerate and Ethofenprox on Penaeus japonicus [weight (10. 6 ± 2. 5) g ] was studied under labo-ratory conditions [water temperature (18. 2 ± 0. 3) ℃] by the semi-static test method. The mean static a-cute 24 h LC50、 48 h LC50、 72 h LC5 0、 96 h LC50 of Fenvalerate on Penaeus japonicus were 1. 52、 0. 810、0. 520、 0. 310 μg·L-1 , respectively. The mean static acute 24 h LC50、 48 h LC50、 72 h LC50、 96 h LC50 of Ethofenprox on Penaeus japonicus were 1. 88、 1. 30、 0. 940、 0. 760 μg · L-1 , respectively. The safe concentration ( SC) of Fenvalerate and Ethofenprox were 0. 069 0 μg·L-1 and 0. 190 μg·L-1 . The results showed that the order from strong to weak of acute toxicity of two pyrethroid insecticides which were belonged to the high-toxic substance on Penaeus japonicus was Fenvalerate>Ethofenprox. As a pond clearing drug, it should be carefully used.关键词
