【 摘 要 】

The persistence and efficacy of growth regulator pyriproxyfen were evaluated in two final concentrations 0.01 and 0.05ppm against Aedes aegypti larvae in laboratory conditions using three types of containers: cement box (45 liters), glass bottle (5 liters)and plastic bucket (20 liters). The tests were carried after 1, 7, 15, 30, 45, 60, 90 and 120 days of treatment against Aedes aegypti larvae 3rd and 4th instar. The percentages of larvae, pupae and adult mortality, the percentage of adult emergence inhibition and time duration of bioassays were calculated. A was observed a persistence of 45 and 90 days by using 0.01 and 0.05ppm final concentrations of pyriproxyfen, respectively, was observed. We observed that mortality in the pupa stage was significantly higher than larvae and adults mortality for all containers and concentrations.
