      Jedna z největších zvířecích invazí probíhá už sto let. Argentinští mravenci během ní ovládli několik světadílů a kvůli oteplování planety pronikají i do dříve chladnějších zemí. Vědci teď popsali, jak si vedou proti moderním pesticidům.

      The study from the University of California, Riverside, found that two common ant-bait insecticides can cause very different changes in Argentine ant behaviour before the ants die. Thiamethoxam made affected ants unusually active and sent them roaming outside the nest, while boric acid caused ants to stop foraging and gather inside. The findings show that unusual ant activity after treatment does not necessarily mean the pesticide has failed.

      Invasive Argentine ants have formed a unique symbiotic relationship with sap-feeding insects, creating challenges for citrus groves and vineyards. First spotted in the U.S. in 1891, their expansion is aided by California's favorable climate and human activity. To effectively manage the situation, it's crucial to tackle both the ant populations and their pest partners as interconnected issues.
