关于病毒杀虫剂的安全问题,国外曾报告了棉花夜蛾、烟夜蛾核多角体病毒感染小白鼠、豚鼠后无病理改变,人吞食棉铃虫核多角体病毒未发现异常。近年来我国先后发现50多种昆虫病毒,作过一些安全试验,证明棉铃虫、桑毛虫核多角体、菜粉蝶颗粒体病毒对鼠、兔、家禽和家畜等均无毒性。但是不同毒株有无危害有待研究。VHA—273棉铃虫核多角体病毒属多粒包埋体病毒。杀虫效果显著。为对该病毒的安全生产和使用提供依据,我们进行了安全试验,未发现对试验动物有致病现象,现将结果报告如下:
On the safety of the virus insecticide, foreign reports of cotton bollworm, NPV infection in mice, guinea pigs no pathological changes, human swallowed bollworm nuclear polyhedrosis virus found no abnormalities. In recent years, China has discovered more than 50 kinds of insect viruses, made some safety tests to prove that cotton bollworm, mulberry nuclear polyhedrosis, cabbage butterfly particle virus on mice, rabbits, poultry and livestock are non-toxic. But whether the different strains are harmful or not needs to be studied. VHA-273 Helicoverpa armigera polyhedrosis virus is a multi-particle embedded virus. Insecticidal effect is remarkable. To provide a basis for the safe production and use of the virus, we conducted safety tests and found no signs of disease in the test animals. The results are reported as follows:
