KEywORdS: Methoprene, mosquito, catch basin, larvicide RECEIVEd: November 8, 2017. Results show that realized environmental concentrations of methoprene were usually 2-5µg/kg (range 2-45µg/kg) and that its motility is limited. In fact, methoprene has been recommended by the World Health Organisation (WHO) for the use in drinking water supplies to control container-breeding mosquitoes in developing countries. Methoprene (or Precor) is not photostable (except in granular products such as Extinguish Fireant Bait and Methoprene Mosquito Granules) and is for indoor use.  |  Three biological replicates were taken, and each replicate contained fat bodies or ovaries isolated from 10 mosquitoes. As methoprene has a delayed control effect on mosquitoes, evaluating the effectiveness of Altosid formulations cannot be done through more simple and direct on-site observations of catch basin dip samples, as performed in studies of bacterial-based formulations. However, both larval development and action of JH analogs are not well studied in these insects because RNA interference does not work well. Methoprene is considered a biological pesticide because rather than controlling target pests through direct toxicity, methoprene interferes with an insect’s lifecycle and prevents it from reaching maturity or reproducing. Under the JH control, the female mosquito becomes competent for the 20E response, blood feeding and vitellogenesis (Raikhel et al., 2005; Riddiford, 2012; Roy et al., 2016; Zhu and Noriega, 2016). The idea with an IGR is that if an insect cannot reach adulthood, it cannot reproduce. Methoprene Mosquito Granules contain an IGR that inhibits the growth of certain insects in their immature stages. These types of larvicides prevent mosquito larvae from completing their immature stage, so they do not make it to the adult stage. When mosquito larvae are exposed to Methoprene, they do not die.

The other is a naturally found bacillus that targets mosquitoes, called Bti. Methoprene is a growth regulator which prevents the larvae of mosquitoes and other insects from becoming adults, by imitating insects’ natural juvenile hormone. Type of … In 1996, after further studies, the EPA concluded that the actual use of methoprene as a mosquito control didn’t spread enough of it to harm other species, and recommended that the restriction “do not use in fish-bearing waters” be removed from the label, and instead, the warning should read, “this product is toxic to aquatic dipteran (mosquitoes) and chironomid (midge) larvae”–though of course its toxicity to mosquito larvae is the whole point. Exposure to nanoceria impacts larval survival, life history traits and fecundity of Aedes aegypti. The EPA stated it is “highly acutely toxic to estuarine invertebrates,” such as crayfish, shrimp and crabs. Oils and films.
