一种新型杀虫生物活性筛选方法的研究
0
()
摘要:
卤虫是一种广温耐高盐的水生生物,由于对毒物敏感、个体微小、容易获得和培养等特点,用于污染物的检毒研究。通过测定常用杀虫剂对卤虫初孵无节幼体的毒力,探讨卤虫作为杀虫活性筛选模型生物的可行性,并研究应用卤虫进行杀虫生物测定的影响因子。

A new screening method for insecticidal activity
()
Abstract:
Artemia salina is a wide temperature and salt-tolerant aquatic organism.Because it is sensitive to poison,small and easy to acquire and cultivate,Artemia salina is often used as bioassay organism to detect the toxicities of pollutants.In this paper,the toxicities of ten pesticides to Artemia nauplii were studied,and its feasibility as a screening model for insecticidal activity was explored.Simultaneously,the impacts of environmental factors on Artemia nauplii bioassay methods were analysed.
Key words:  Artemia salina  insecticidal activity  bioassay  LC50
