Methoprene
J Am Mosq Control Assoc 2007;23(2 Suppl):225-39.PMID:17853608DOI:10.2987/8756-971X(2007)23[225:M]2.0.CO;2.
A brief overview is presented of the discovery and development of s-methoprene and some other juvenile hormone mimics. The identification of the natural juvenile hormones is described along with an outline of the part they play in the hormonal control of insect development. The properties and commercial applications of s-methoprene are presented with emphasis on its use in mosquito control and its minimal impact on the environment.
Mutagenicity testing of the juvenoid Methoprene (ZR-515) by means of the Drosophila wing spot test
Mutat Res 1987 Jul;188(3):209-14.PMID:3110612DOI:10.1016/0165-1218(87)90091-7.
The juvenile hormone analogue methoprene, which is used in insect pest control, was subjected to mutagenicity testing by means of the Drosophila wing spot test. Larvae heterozygous for recessive wing trichome mutations were exposed to a sublethal dose of methoprene. Wings of emerged adult females were inspected for the presence of phenotypically mutant mosaic spots. Methoprene exhibited a weak mutagenic effect. The fact that only small mosaic clones were induced is discussed.
Environmental safety review of Methoprene and bacterially-derived pesticides commonly used for sustained mosquito control
Ecotoxicol Environ Saf 2017 May;139:335-343.PMID:28187397DOI:10.1016/j.ecoenv.2016.12.038.
Some pesticides are applied directly to aquatic systems to reduce numbers of mosquito larvae (larvicides) and thereby reduce transmission of pathogens that mosquitoes vector to humans and wildlife. Sustained, environmentally-safe control of larval mosquitoes is particularly needed for highly productive waters (e.g., catchment basins, water treatment facilities, septic systems), but also for other habitats to maintain control and reduce inspection costs. Common biorational pesticides include the insect juvenile hormone mimic Methoprene and pesticides derived from the bacteria Bacillus thuringiensis israelensis, Lysinibacillus sphaericus and Saccharopolyspora spinosa (spinosad). Health agencies, the public and environmental groups have especially debated the use of Methoprene because some studies have shown toxic effects on non-target organisms. However, many studies have demonstrated its apparent environmental safety. This review critically evaluates studies pertinent to the environmental safety of using Methoprene to control mosquito larvae, and provides concise assessments of the bacterial larvicides that provide sustained control of mosquitoes. The review first outlines the ecological and health effects of mosquitoes, and distinguishes between laboratory toxicity and environmental effects. The article then interprets non-target toxicity findings in light of measured environmental concentrations of Methoprene (as used in mosquito control) and field studies of its non-target effects. The final section evaluates information on newer formulations of bacterially-derived pesticides for sustained mosquito control. Results show that realized environmental concentrations of Methoprene were usually 2-5µg/kg (range 2-45µg/kg) and that its motility is limited. These levels were not toxic to the vast majority of vertebrates and invertebrates tested in laboratories, except for a few species of zooplankton, larval stages of some other crustaceans, and small Diptera. Studies in natural habitats have not documented population reductions except in small Diptera. Bacterial larvicides showed good results for sustained control with similarly limited environmental effects, except for spinosad, which had broader effects on insects in mesocosms and temporary pools. These findings should be useful to a variety of stakeholders in informing decisions on larvicide use to protect public and environmental health in a 'One Health' framework.
Methoprene treatment increases activity, starvation and desiccation risk of Queensland fruit fly
J Insect Physiol 2022 Jan;136:104340.PMID:34838789DOI:10.1016/j.jinsphys.2021.104340.
Juvenile hormone is an important regulator of sexual development in insects, and application of Methoprene, a juvenile hormone analogue, together with access to a protein-rich diet, has been found to accelerate sexual maturation of several tephritid fruit fly species including Queensland fruit fly Bactrocera tryoni ('Q-fly'). Such accelerated development is a potentially valuable means to increase participation of released males in sterile insect technique programs. However, there is a risk that benefits of accelerated maturation might be countered by increased vulnerability to starvation and desiccation. The present study investigates this possibility. After emergence, flies were treated with three levels of Methoprene (0, 0.05%, and 0.5%) incorporated into a diet of sugar and yeast hydrolysate for two days after emergence. Survival of groups and individual flies was assessed under conditions of food stress, food and water stress, and ad libitum access to diet, and survival of individual flies was also assessed under desiccation stress. Most flies provided ad libitum access to diet were still alive at 7 days, whereas all stressed flies died within 4 days. Desiccation stressed flies had the shortest survival followed by food and water stress, and then food stress. Methoprene supplements increased susceptibility of flies to each stress. Flies subjected to food and water stress had the least lipid reserves at death, whereas flies subjected to desiccation stress retained the least water reserves. To investigate mechanisms that might underlie reduced survival under stress; we also quantified activity level of flies that were subjected to food and water stress and desiccation stress. Activity level was greater for flies provided Methoprene, but did not vary with stress type or sex, suggesting that increased vulnerability of flies to stress is related to elevated metabolism associated with elevated activity. Deleterious effects of Methoprene supplements on stress tolerance indicate a need for careful consideration of the conditions that will be encountered by flies in the field before deploying Methoprene as a pre-release treatment in Q-fly sterile insect technique programs.
The juvenile hormone receptor as a target of juvenoid "insect growth regulators"
Arch Insect Biochem Physiol 2020 Mar;103(3):e21615.PMID:31502704DOI:10.1002/arch.21615.
Synthetic compounds that mimic the action of juvenile hormones (JHs) are founding members of a class of insecticides called insect growth regulators (IGRs). Like JHs, these juvenoids block metamorphosis of insect larvae to reproductive adults. Many biologically active juvenoids deviate in their chemical structure considerably from the sesquiterpenoid JHs, raising questions about the mode of action of such JH mimics. Despite the early deployment of juvenoid IGRs in the mid-1970s, their molecular effect could not be understood until recent discoveries of JH signaling through an intracellular JH receptor, namely the ligand-binding transcription factor Methoprene-tolerant (Met). Here, we briefly overview evidence defining three widely employed and chemically distinct juvenoid IGRs (Methoprene, pyriproxyfen, and fenoxycarb), as agonist ligands of the JH receptor. We stress that knowledge of the target molecule is critical for using these compounds both as insecticides and as research tools.
