研究者らは、乾材シロアリの駆除を目的として、化学物質ビストリフルロンを用いた標的型処理技術を開発した。この手法は昆虫の脱皮プロセスを阻害するもので、実験室での試験において高い死亡率を達成した。
カリフォルニア大学リバーサイド校の科学者チームは、アメリカカンザイシロアリを対象にビストリフルロンの試験を行った。この化合物は、新しい外骨格の形成に必要なキチンの生成を阻害し、約2か月でコロニーの崩壊を引き起こす。試験の一つでは、シロアリのごく一部に接触させただけで、摂食行動を通じてコロニー全体に成分が拡散し、60日以内に96パーセントの死亡率を記録した。

A March 5, 2026 guide from Wellness Mama describes a prevention-first approach to household ants, recommending tighter food storage, cleaning to disrupt pheromone trails, and several DIY barriers and baits—while urging caution with ingredients like borax around children and pets.
A hybrid population of honeybees in Southern California demonstrates natural resistance to Varroa mites, a major threat to bee colonies. Researchers at UC Riverside found these bees carry 68% fewer mites and require far less chemical treatment. The discovery, detailed in a new study, suggests early-life defenses in larvae may hold the key.

Following the deaths of six children in Soweto from terbufos-contaminated food, the South African government has published a ban on the highly toxic pesticide in January 2026. Emeritus Professor Leslie London, who chaired the relevant ministerial committee, highlighted flaws in the country's outdated pesticide regulations. The ban awaits public comments until late February.
Scientists at the National Autonomous University of Mexico have created three new antibiotics using compounds extracted from scorpion venom and habanero peppers. The effort targets tuberculosis and other bacteria that have grown resistant to current treatments.

Researchers at the University of York have identified a protein called ESB2 that acts as a molecular shredder, enabling the African trypanosome parasite to evade the human immune system. The parasite, which causes sleeping sickness, uses ESB2 to precisely edit its genetic instructions in real time. This breakthrough solves a 40-year mystery in the parasite's biology.
