Effects of pyriproxifen on aedes japonicus development and its auto-dissemination by gravid females in laboratory trials


Tuten, Holly C; Moosmann, Philipp; Mathis, Alexander; Schaffner, Francis (2016). Effects of pyriproxifen on aedes japonicus development and its auto-dissemination by gravid females in laboratory trials. Journal of the American Mosquito Control Association, 32(1):55-58.

Abstract

In a series of laboratory experiments, we investigated the effects of the juvenile-hormone analog pyriproxyfen on the inhibition of Aedes japonicus adult emergence after exposure of late-stage (3rd/4th) larvae (either field-collected or lab-reared from field-collected eggs) to pyriproxyfen. Emergence inhibition was 74%, 83%, 86%, and 92% at 0.01, 0.5, 2.5, and 5 μg/liter, respectively. Additionally, following a 1-day exposure of larvae to pyriproxyfen-containing water (5 μg/liter), and for a separate cohort exposed to that same water 10 days later, significantly more pupae died resulting in fewer adults emerged in the treatment versus control group. In 4 tent trials, gravid adult females were able to auto-disseminate a 5% pyriproxyfen powder to larval development habitats at high enough concentrations to cause a significant increase in inhibition of adult emergence. Therefore, we conclude that pyriproxyfen has a great potential for use in controlling this invasive cryptic breeder.
