Toxicity of Methoprene as Assessed by the Use of a Model Microorganism [PDF]

Toxicology in Vitro, 2005
Methoprene is an insect juvenile growth hormone mimic, commonly used as a pesticide. Although widely used for the control of several pests, toxic effects on organisms of different phyla have been reported. These events triggered studies to clarify the mechanisms of toxicity of this insecticide putatively involved in ecological issues.

Resistance to S-Methoprene Correlates with Pyriproxyfen Resistance in Field-Collected Culex pipiens [PDF]

Insects
The increasing prevalence of insecticide resistance threatens the efficacy of Integrated Mosquito Management (IMM) programs, particularly in regions reliant on chemical control for vector-borne disease prevention.

Methoprene.

Journal of the American Mosquito Control Association, 2007
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.

Dual S-methoprene and Lysinibacillus sphaericus larvicide use leads to multiple independent, and not cross-resistance in Culex pipiens. [PDF]

PLoS ONE
S-methoprene, an insect growth regulator, and Lysinibacillus sphaericus (Ls), an entomopathogenic bacterium, are important larvicides used to control Culex pipiens [L.] mosquitoes, the primary vector of West Nile virus, in the Chicago, IL USA region ...

Vapor-phase (S)-methoprene alters cuticular hydrocarbons in the Argentine ant (Hymenoptera: Formicidae) [PDF]

Scientific Reports
The Argentine ant, Linepithema humile (Mayr), is one of the world’s most damaging invasive species. Current control strategies for L. humile rely on neurotoxic insecticides; however, their use is increasingly limited due to their environmental impacts ...

Evaluating the Long-Term Efficacy of Four Active Ingredients Against Rhyzopertha dominica (F.) (Coleoptera: Bostrichidae) and Sitophilus oryzae (L.) (Coleoptera: Curculionidae) on Stored Sorghum in the United States [PDF]

Insects
Grain protectants are insecticide formulations applied directly to raw grain to prevent and control insect infestations in bulk storage; however, their efficacy depends on insect species, commodity, and grain quality.

Adulticidal Activity of the Insect Growth Regulators Methoprene and Cyromazine in House Flies (Musca domestica L.): Evidence from Feeding Trials [PDF]

Biology
House flies (Musca domestica L.) are major vectors of numerous pathogens affecting both humans and animals. The global distribution of house flies has been steadily increasing the expansion of human settlements, increased waste production, and the growth

Extreme resistance to S-methoprene in field-collected Culex pipiens (Diptera: Culicidae) across the Chicago, IL region [PDF]

Scientific Reports
Insect growth regulators, like S-methoprene, are heavily relied upon worldwide for larval mosquito chemical control due to their target specificity and long-lasting effects.
