Ny kemikalie bekämpar termiter med minimal skada för människor

Forskare har utvecklat en målinriktad behandling med kemikalien bistrifluron för att bekämpa angrepp av torrtetermiter. Metoden stör insekternas ömsningsprocess och uppnådde hög dödlighet i laboratorietester.

Forskare vid University of California, Riverside testade bistrifluron mot västliga torrtetermiter. Föreningen blockerar bildandet av kitin som krävs för nya exoskelett, vilket leder till att kolonin kollapsar inom cirka två månader. I ett test uppnåddes en dödlighet på 96 procent inom 60 dagar när endast en liten andel av termiterna först exponerades, då ämnet spreds genom kolonin via deras födobeteende.

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 Emeritus Professor Leslie London, who chaired the relevant ministerial committee, highlighted flaws in the country's outdated pesticide regulations.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.

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.
