Sevin, (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.
Carbaryl is often inexpensively produced by direct reaction of methyl isocyanate with 1-naphthol. [5]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 metabolism of bees and humans is sufficiently different that bees can safely collect nectars from plants that contain compounds toxic to humans. The honey produced by bees from these toxic nectars can be poisonous if consumed by humans. In addition, natural processes can introduce toxic substances into honey produced from nontoxic nectar.
The most common chemical control method used is carbaryl (typically sold as "Sevin Dust") bait. This bait kills both the Mormon crickets that eat the bait and the crickets that eat crickets that have eaten the bait.
Cypermethrin is highly toxic to fish, bees and aquatic insects, according to the National Pesticide Information Center (NPIC) (previously National Pesticides Telecommunication Network) in the USA [1]. It is found in many household ant and cockroach killers, including Raid, Ortho, Combat, ant chalk, and some products of Baygon in Southeast Asia.
