Abstract：Objective To investigate the control effect of a new mosquito control film on larvae and pupae of Aedes albopictus, and to evaluate its influence on mosquito growth and development and its lethal activity. Methods From July to September 2019, 30 larvae or pupae of Ae. albopictus were placed in enamel pots containing different types of insecticides using the larval dipping method in the laboratory, and their death time and the status of pupation or emergence were observed and recorded. SPSS 18.0 software was used to calculate the median lethal time (LT50) and 95% confidence interval (CI), establish a toxicity regression equation, and conduct a statistical analysis. Results The Ae. albopictus pupae in the new mosquito control film group and the temephos group had 24-hour mortality rates of 100% and 2.22%, respectively, with a significant difference between the two groups (χ2=172.174, P<0.001); the surviving pupae of the temephos group all emerged as adult mosquitoes. The larvae in the Bacillus sphaericus group, the B. thuringiensis subsp. israelensis group, and the temephos group all had a 24-hour mortality rate of 100%. The larvae treated with the new mosquito control film had 24-hour mortality rates of 55.56% and 60.00% when observed once every 1 and 5 hours, respectively, with no significant difference between the two observation groups (χ2=0.364, P>0.05); all the surviving larvae in the two groups did not pupate. The larvae in the older group and the younger group had 24-hour mortality rates of 90.00% and 18.89%, respectively, after being treated with the new mosquito control film, with a significant difference between the two groups (χ2=91.747, P<0.001). Conclusion The new mosquito control film has good control effect on larvae and pupae of Ae. albopictus, which can be used for mosquito prevention and control.
