有机氯类杀虫剂二二三从开始用于防制人体疾病的媒介昆虫以来已30年,而怀疑家蝇和常见家蚊对它产生抗性也已有28年了。在那段时期里,已知有108种对公共卫生有重要意义的节肢动物对某些杀虫剂产生了抗性。虽然近6年内只增多了6种,但是抗性昆虫的地域分布更广了。对新的有机磷类杀虫剂和对有机氯类的二二三和666-狄氏剂一样也增添了抗性。现已知道,除对二二三有抗性的61种和对狄氏剂有抗性的91种外,有27种对有机磷产生了抗性,事实上,仅
It has been 30 years since the organochlorine insecticide 2333 started to be a vector insect for the control of human diseases, and it has been 28 years since it was suspected of housefly and common house mosquito. During that time, it was known that 108 species of arthropods of public health importance were resistant to certain pesticides. Although there are only 6 species increased in the past 6 years, the geographical distribution of resistant insects has been broader. It also adds resistance to new organophosphate insecticides and to organochlorines like 233 and 666-Dieldrin. It is known that 27 species of organophosphorus are resistant to 61 species resistant to 233 and 91 species resistant to dieldrin. In fact, only
