Current, chemical control is master of Blattella germanica and vector insects population number of important means, quasi pyrethrins insecticides as a new generation of insecticides, since the 20th century, 80 years is widely used in agriculture, forestry and disease vector insects control. But, there are many kinds of insects to these insecticides in the resistance, insect resistance has become the crux of the many disease vector insect chemical control identity constraints. Chemical prevention and control of the German cockroach cockroach class and its relevant research in recent years of concern. Real time and accurately affirmation of insects resistant to the birth, growth and the degree of resistance to formulate reasonable chemical control strategy is quite important, on the mechanism of the toxicity of pesticide research and rapid precise resistance detection method is the task of the basic. In this paper, Blattella germanica susceptible strains as test plants, according to the national standard GB 13917. One one one 13917 1. 8 a 92 "pesticide registration of hygienic insecticides laboratory efficacy test methods" and slightly modified chapeau affirmed the experimental conditions under cypermethrin on Blattella germanica susceptible strain semi induced death of concentration, and through the process of repeated trials affirmed the highest induced death rate does not exceed 30% of high effect cypermethrin five sub induced death concentration of drug solution. Watching the action of drug solution concentration differences on Blattella germanica susceptible strains and influence caused by death of probation. The test results showed that cypermethrin can seriously affect the normal activities of Blattella germanica to balance the war, and has a strong effect on the death caused by the German cockroach sensitive strains, and appear in the application of five subtypes of death caused by the concentration of Blattella germanica susceptible strains were determined concentration effect tests of Cypermethrin permethrin 24 hours and 48 hours, 72 hours, 96 hours, 120 hours, 144 hours from time to time, acetylcholinesterase (AChE), superoxide dismutase (SOD), Na K ATPase, Ca ATPase, glutathione peroxidase (GPX) activity of the timing change, further explore mechanism of action of beta cypermethrin and the activity of German cockroach differences between dose effect and time effect relationship. Test results show that the Blattella germanica in the six enzymes are the main targets of beta Cypermethrin, grateful to ache, Na K ATPase and Ca ATPase is obvious restraint effect and has a certain concentration effect and time effect relationship; on SOD, GPX is obviously attractive effect, to a certain level, drug revulsive action and beta cypermethrin concentrations appeared positive correlation relationship, with different concentration of the attractant effect on the effects of time difference. Different concentrations of Cypermethrin cause of Blattella germanica in branching enzyme activity of the timing change reminder, in the application of quasi process of pyrethroid insecticides 目录: |
