Propoxur is highly toxic to honey bees. The LD50 for bees is greater than one ug/honey bee. [citation needed] Highly toxic Acephate [25] Orthene Organophosphate: 3 days Acephate is a broad-spectrum insecticide and is highly toxic to bees and other beneficial insects. [26] Moderately toxic Azinphos-methyl [27] Guthion, Methyl-Guthion ...
In sufficient quantities, such chemicals can poison and even kill the bee. The effects of alcohol on bees have long been recognized. For example, John Cumming described the effect in an 1864 publication on beekeeping. [1] When bees become intoxicated from ethanol consumption or poisoned with other chemicals, their balance is affected.

How they kill honey bees. Drew Martin. April 4, 2024 at 6:00 AM. The honey bee killer the yellow-legged hornet (Vespa velutina) has now been found a second time in South Carolina.
The Asian giant hornet is intensely predatory; it hunts medium- to large-sized insects, such as bees, [35] [89] other hornet and wasp species, beetles, hornworms, [90] and mantises.

A person who accidentally picks fruit with a feeding hornet can be attacked by the disturbed insect. The adults also attack various insects, which they kill with stings and jaws. Due to their size and the power of their venom, hornets can kill large insects such as honey bees, grasshoppers, locusts, and katydids without difficulty.
However, some research has shown neonicotinoids affecting mason bees and bumblebees more negatively than honey bees, which are inconsistently affected. [8] Research suggests potential toxicity to honey bees and other beneficial insects even with low levels of exposure, with sublethal effects that negatively impact the survival of colonies.
