Efficacy of Combinations of Methoprene and Deltamethrin as Long-Term Commodity Protectants

open access: yesInsects, 2019
Wheat, corn, and brown rice were treated with different combinations of a deltamethrin suspension concentrate (SC) formulation and a new emulsifiable concentrate (EC) formulation, at rates of either 0.5 or 1.0 ppm alone or in combination with 1.25 and 2 ...

Plant Virus‐Induced Inheritable Apoptosis Drives Reproductive Costs in Female Insect Vectors to Balance Viral Biparental Transmission

open access: yesAdvanced Science, Volume 13, Issue 5, 27 January 2026.
Rice gall dwarf virus (RGDV), transmitted biparentally by leafhopper vector to their offspring, exploits the capsid protein to induce inheritable ovarian apoptosis via insulin‐driven PI3K/AKT/FoxO signaling axis. This mechanism enhances infection but reduces female reproductive fitness, causing inefficient maternal transmission.

Thin layer chromatographic analysis of pteridine-like pigments in the migratory locust, Locusta migratoria migratorioides (Orthoptera: Oedipodidae)

open access: yesEuropean Journal of Entomology, 2003
Acidic methanolic extracts of haemolymph, cuticle and eyes of larvae and adults of the migratory locust, Locusta migratoria migratorioides (R. et L.), were subjected to thin layer chromatography.

Scaffold‐Hunting From Pyriproxyfen: A Biochemoinformatic Route to Novel Insecticidal Leads

open access: yesBioMed Research International, Volume 2026, Issue 1, 2026.
Vector‐borne diseases remain a critical global health concern, particularly in tropical and subtropical regions, where socioeconomic conditions often favor vector proliferation. Pyriproxyfen, a juvenile hormone analog used as a larvicide against Aedes aegypti, is known for its fast‐acting efficacy, low toxicity, and favorable environmental profile ...

Metabolism and interactions of the castes of the imported fire ant, Solenopsis invicta, treated and exposed to methoprene alone and synergized

open access: yes, 1976
Vita.Studies are presented on the metabolism of methoprene, an insect growth regulator, by the castes of the imported fire ant, (IFA), Solenopsis invicta Buren. The relative rates of metabolism of methoprene in the IFA castes were in the following order:

Regulation of the development of flight muscles in long-winged adults of the flightless bug Pyrrhocoris apterus (Heteroptera: Pyrrhocoridae)

open access: yesEuropean Journal of Entomology, 2008
We studied the development of the indirect flight muscles and reproductive organs in long-winged (macropterous) adults of the flightless bug Pyrrhocoris apterus (L.) and the factors involved in flight muscles histolysis by means of total protein analysis.

Development of an Analytical Method for Methoprene in Rice by HPLC

open access: yesFood Hygiene and Safety Science (Shokuhin Eiseigaku Zasshi), 1994
A new analytical method was developed for the determination of methoprene, an insecticide, in rice. Methoprene was extracted with n-hexane from powdered samples. The concentrated n-hexane extract was purified by distillation in a Dean-Stark apparatus for 1.5hr, and then cleaned-up with a Sep-pak Florisil cartridge. The eluate was used as test solution.

Effects of methoprene on Coptotermes formosanus (Isoptera: Rhinotermitidae)

open access: yes, 1987
Methoprene affected differentiation and survival of Coptotermes formosanus Shiraki in laboratory studies. At 5, 9, 13, and 17 weeks, superfluous intercastes and presoldiers were produced when termites were allowed to feed on concentrations of 1,000 and 2,

Methoxyfenozide and methoprene toxicity to Sf9 cells.

open access: yes, 2013
Cell viability was followed by the MTT test at 24, 48 and 72 h post-treatment of Sf9 cells by methoxyfenozide (A) or methoprene (B). Data are the mean of three independent experiments with SE.
