Microbial pesticides can prevent and control diseases and pests of crops, and has become one of the important measures to ensure food and environmental safety. However, the potential harm of microbial pesticides to humans and animals is a serious concern at home and abroad. In this paper, we have investigated the infectivity and pathogenicity of a representative of viral microbial pesticides, helicoverpa armigera nuclear polyhedrosis virus (HaNPV), by specific and highly sensitive polymerase chain reaction technology. The results show that HaNPV can be gradually cleared in a short time after getting into blood of experimental rats, and does not infect other tissues or organs of animals;also indicate that the test subjects are not infectious to experimental rats after intravenous injection of HaNPV. Our method has good specificity and repeatability, and could provide an important reference for establishment of infectivity and pathogenicity detection methods for viral microbial pesticides in future. 相似文献

为了了解广东省农村种植区农药使用现状,对广东省11个村共300位务农人员进行了问卷访谈调查。调查显示,对以水稻种植为主的种植区,农户主要施用的农药为有机磷农药、联吡啶类除草剂、微生物杀虫剂、杂环类杀菌剂以及氨基甲酸酯农药;农药施用频率为视情况而定的比例达41.98%;施用时间主要是在出苗后(35.04%);34.21%的被调查者对农药残留认识表示为根本不知何为环保、低残留农药,仅有0.12%的农户对环保和低残留农药有所了解;对生态农业平均有66.64%的接受调查的农户表示不了解,甚至没听过。 相似文献
