室内测定结果表明,8种杀虫杀螨剂对柑桔全爪螨和腹管食螨瓢虫的成虫与幼虫的毒性,以双甲脒对柑桔全爪螨雌成螨的药效最高;三氯杀螨醇、机油乳剂和柴油乳剂对腹管食螨瓢虫成虫有选择作用,三氯杀螨醇、杀虫脒、普特丹和双甲脒对腹管食螨瓢虫幼虫(三龄)有选择作用,其中双甲脒选择作用最高,对腹管食螨瓢虫最为安全。柴油乳剂对腹管食螨瓢虫幼虫敏感,而水胺硫磷对腹管食螨瓢虫成虫和幼虫均较敏感。在常用三氯杀螨醇和杀虫脒的老果园,因害螨产生抗药性,对食螨瓢虫幼虫失去了选择作用,其毒性比均在1.0以下。
The results of laboratory tests showed that the toxicity of 8 kinds of insecticides and acaricide to adults and larvae of Panonychus citri and Abdominal amphibian was the highest with amitraz, Dicofol, oil emulsion and diesel oil emulsion have the selective effect on the adults of the abdomen tube, mite and ladybug, and dicofol, chlordimeform, potentan and amitraz have the selective effect on larvae of the ladybug (third instar) Formamidine has the highest selective effect and is the safest for dietary mites and ladybugs in the abdominal tube. Diesel oil emulsion is sensitive to the larvae of the food-web mites and ladybugs, while the acetaminophen is more sensitive to adults and larvae of the larvae of the mites. In the old orchards commonly used dicofol and chlordimeform old, because of pest mites produce resistance, larvae of food mites ladybugs lost the role of selection, the toxicity ratio of 1.0 below.
