Research clearly shows that a miniscule dose of a neonicotinoid may kill a bee within 48 hours, yet an even smaller dose may still be lethalâ¦but the bee will survive longer, perhaps for example, for up to 8 days (eg.see Suchail et al 2001) .hey are in a different insect order from bees (they are of the cockroach order Blattodea). However, patents for products containing imidacloprid do claim efficacy for controlling insects from the order Hymenoptera (to which bees belong) â including Vespa (wasps) - read more here.
To investigate, scientists looked at two common pesticides: neonicotinoids, which are used to control pests on oil seed rape and other crops, and a group of organophosphate chemicals called coumaphos, which are used to kill the Varroa mite, a parasite that attacks the honey bee.cientists have found that two types of chemicals called neonicotinoids and coumaphos are interfering with the insect's ability to learn and remember. Experiments revealed that exposure was also lowering brain activity, especially when the two pesticides were used in combination.
