Cockroaches will soon be impossible to kill with standard pesticides, as they can develop cross-resistance to poisons they’ve never encountered within a single generation, an ominous new study has found.

Abstract
The German cockroach (Blattella germanica L.) is a worldwide pest that lives exclusively in human environments. B. germanica threatens human health by producing asthma-triggering allergens, vectoring pathogenic/antibiotic-resistant microbes, and by contributing to unhealthy indoor environments. While insecticides are essential for reducing cockroach populations and improving health outcomes, insecticide resistance has been a consistent barrier to cockroach control since the 1950s. We conducted seminal field studies to compare three insecticide resistance intervention strategies for cockroaches and evaluated resistance evolution across multiple generations. Using pre-treatment resistance assessment to drive decisions, we found that single active ingredient (AI) treatments can successfully eliminate cockroaches if starting resistance levels are low. We further established that rotation treatments intuitively reduce selection pressure, and are effective when insecticides with no/low resistance are used. We also found that mixture products containing thiamethoxam + λ-cyhalothrin AIs were universally ineffective and highly repellent; and finally, evolution of cross-resistance among AIs is a significant, previously unrealized challenge.

entomólogos de la Universidad Purdue de Indiana,

C’est une étude d’une université payé par les Sacklers non ? Le nom met mes alarmes au rouge.

Un titre qui ouvre une immense possibilité d’interprétation !

Les cafards du #PS sont devenus #enMarche.

A vos interprétations, je lance le concours.

L’Université Purdue est une université publique qui fait plein de choses. Il est possible que les Sackler ait financé un département, mais pas toute l’université...

Peut-être que tu confonds avec Purdue Pharma, une entreprise privée qui appartient bien aux Sackler mais qui n’a pas de liens avec l’université homonyme :

Oui je pensait que c’etait pour Purdue Pharma alors que c’est a cause du fondateur John Purdue.
