(b) Sevin XLR Carbamate: High risk to bees foraging even 10 hours after spraying; 3 – 7 days (b) 8 hours @ 1.5 lb/acre (1681 g/Ha) or less. Bees poisoned with carbaryl can take 2–3 days to die, appearing inactive as if cold. Sevin should never be sprayed on flowering crops, especially if bees are active and the crop requires pollination.
C 10 H 7 OH + CH 3 NCO → C 10 H 7 OC(O)NHCH 3. Alternatively, 1-naphthol can be treated with excess phosgene to produce 1-naphthyl chloroformate, which is then converted to carbaryl by reaction with methylamine. [5] The former process was carried out in Bhopal. In comparison, the latter synthesis uses exactly the same reagents, but in a ...

There are two types of pyrethroids: those with and without α-cyanogroup. The neurotoxicity of bifenthrin is based on the affinity to the voltage-gated sodium channels (in insects as well as mammals). The pyrethroids with an α-cyanogroup block the sodium-channel permanently, causing the membrane to be permanently hyperpolarized.

Some bees that consume ethanol become too inebriated to find their way back to the hive, and die as a result. [2] Bozic et al.

[3] Some bees become more aggressive after consuming alcohol. [4]
