Effects of Methoprene on Lycoriella mali (Diptera: Sciaridae)

Journal of Economic Entomology, 1988
Methoprene, a juvenile hormone analog, is widely used for control of larvae of the mushroom pest Lycoriella mali (Fitch) in compost. The effects of methoprene applied to the eggs. first instars, and fourth instars were investigated. Methoprene was slightly ovicidal to eggs 24 h old. Maximum inhibition of hatching was 27%. Eggs were most sensitive when

Genetic variation for methoprene resistance in Drosophila melanogaster

Journal of Insect Physiology, 1988
Abstract Methoprene, a chemical analogue of juvenile hormone, is highly toxic to larvae of Drosophila melanogaster. The amount of naturally occurring resistance to methoprene was determined in genetically well-defined strains of Drosophila having a second or third chromosome extracted from natural population flies and inserted into an isogenic ...

Synthesis ofS-(+)-methoprene

Russian Chemical Bulletin, 1993
An optically active juvenile hormone analogue,S-(+)-methoprene (1), is synthesized in six steps from technical gradeS-(+)-3,7-dimethyl-1,6-octadiene (“(+)-dihydromyrcene”, e.e. −50%) by a novel procedure which begins with selective hydroalumination-oxidation to giveS-(-)-citronellol.

Effects of Sustained-Release Methoprene and a Combined Formulation of Liquid Methoprene and Bacillus thuringiensis israelensis on Insects in Salt Marshes

Archives of Environmental Contamination and Toxicology, 2000
Aquatic insects are an important component of the food web in salt marshes, therefore it is necessary to test whether pesticides used to control mosquitoes in salt marshes are safe for nontarget insects. We tested the nontarget effects of a combined formulation (duplex) of Bacillus thuringiensis israelensis (B.t.i.) and liquid methoprene (an insect ...

Methoprene and control of stored-product insects

Journal of Stored Products Research, 2018
Abstract Estimated direct and indirect losses of grains and grain-based products caused by stored-product insects range from about 10% in temperate regions to almost 50% in humid tropical areas. Pest management strategies in bulk grains include the use of fumigants such as phosphine and sulfuryl fluoride, and grain protectants, which are sprayed ...

Methoprene Interferes with Mosquito Midgut Remodeling During Metamorphosis

Journal of Medical Entomology, 2003
Many juvenile hormone analogs interfere with insect metamorphosis, a property that makes them useful in insect control and as investigatorial tools with which to study metamorphic mechanisms. We report that one such analog, methoprene, interferes with mosquito metamorphic midgut remodeling. Methoprene treated Aedes aegypti (L.), Aedes albopictus (Skuse)
