Juvenile hormone‐mediated accelerated post‐flight recovery of ovarian development in Loxostege sticticalis (Lepidoptera: Crambidae)

New Plant Protection, Volume 3, Issue 1, March 2026.
Flight in female beet webworms (Loxostege sticticalis) promotes an increase in feeding, thereby enhancing abdominal energy reserves. Following flight, the flight muscles undergo accelerated histolysis, and the energy substances undergoing histolysis are redirected to the ovaries. These two processes collectively promote ovarian development.

Environmental Factors Affecting Methoprene Concentrations for West Nile Virus Control in a Storm Sewer System

, 2009
To address vector-borne West Nile virus in Canada, chemical larvicides (methoprene) are applied to storm sewer system catch basins (CBs) to control mosquitoes. This study assessed the fate and transport of methoprene in such systems over time relative to

Methoprene and Temperature Stimulation of Emergence and Longevity in Adults of Osmia Rufa L. (Megachilidae; Apoidea) During Wintering Period

Journal of Apicultural Science, 2017
In this study methoprene, a juvenile hormone analogues, was tested as a factor that stimulates the end of diapause, bee activation and emergence. In addition, the survival of bees was checked when combined with an application of methoprene.

Integrated In Silico, In Vivo, and Deep Learning Approaches in the Discovery of Novel Candidate Molecules for Aedes aegypti Control

Archives of Insect Biochemistry and Physiology, Volume 121, Issue 2, February 2026.
An integrated computational/experimental workflow was used to identify new candidate molecules for Aedes aegypti control. Docking of 1,070 chalcones against mJHBP, followed by in vivo assays, identified 4′‐chloro‐4‐methoxychalcone (2c) as the most active larvicide candidate.

Evaluation of nontarget effects of methoprene applied to catch basins for mosquito control

, 2010
The mosquito larvicide methoprene is a juvenile growth hormone mimic that is widely used to control mosquito larvae in stormwater catch basins. This study addresses two concerns pertaining to methoprene\u27s use for mosquito control.

A randomized, controlled field study to assess the efficacy and safety of lotilaner (Credelio™) in controlling fleas in client-owned cats in Europe

Parasites & Vectors, 2018
Background Lotilaner is a new isoxazoline developed as an oral ectoparasiticide for cats and dogs. Its safety, rapid killing onset of action and sustained speed of fleas and ticks kill for a minimum of one month after administration, were demonstrated in

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

Advanced 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.

Methoprene modifies adipokinetic hormone characteristics in the firebug Pyrrhocoris apterus (Heteroptera: Pyrrhocoridae)

European Journal of Entomology, 2010
In the present study the hypothesis that there is a feedback between juvenile hormone and adipokinetic hormones (AKHs) was investigated by topical application of the juvenoid methoprene on 9-day-old adult males of the firebug Pyrrhocoris apterus.

Lessons learned exploiting a multi‐year large‐scale data set derived from operational quality assessment of mosquito larval treatments in rain catch basins

Pest Management Science, Volume 81, Issue 10, Page 6630-6638, October 2025.
Results highlight opposite associations between percentages of positive rain catch basins treated with diflubenzuron and Bacillus against mosquito larvae and/or pupae and the intervals between treatments and inspections, and spatial variability in vector control.

Concentration and Residual Efficacy of Methoprene in a Running Ditch

Journal of Pesticide Science, 1992
Altosid 10F [methoprene (isopropyl 11-methoxy-3,7,11-trimethyl dodeca-2,4-dienoate) 10%を活性炭に含有させた徐放製剤] を流れのある排水路中に投入した場合の methoprene の残留濃度を測定し, その効力発現機構について考察した. 試験は, ユスリカが生息している水路 (w, 1.4m; d, 0.2m; 流速, 15.2cm/sec) で行なった. 薬剤濃度は, 1ppm (1時間流量当たりのAI), である. 薬剤処理後, 10, 50, 150, 500m下流地点で水路の底から採取した砂泥約210g (表面積109.3cm2) 中の methoprene 残留量は, 1日目には, それぞれ, 27.5,
