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.

Pollen Exposed to Aerial Pesticide Spray Is a Major Exposure Pathway for Stingless Bees [PDF]

Ecology and Evolution
Testing possible exposure routes of pesticides is essential for assessing the risks to pollinators. In Australia, the pesticide Bacillus thuringiensis var. israelensis (Bti) is widely used in mosquito control programs and applied aerially to mangrove and

Methoprene, a Juvenile Hormone Analog, Causes Winter Diapause Elimination in Univoltine Bee Species Osmia bicornis L. [PDF]

Animals, 2023
Osmia bicornis syn. O. rufa is a univoltine bee species in which adults fly in spring and the offspring overwinter as cocooned imagoes. The flight period of solitary bees is short, so methods of control for development and emergence time are needed to ...

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.

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 ...

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.

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.
