The disposition of carbaryl in the hepatopancreas, haemolymph and embryos of the viviparous scorpion, Heterometrus fulvipes (Koch) during gestation.

1. The disposition of carbaryl in the hepatopancreas and haemolymph of maternal animals and embryos of H. fulvipes (scorpion) after administration of a single sublethal dose was studied by g.l.c. 2. High levels of carbaryl were observed in haemolymph at 10 min, and in hepatopancreas at 1 h after administration. About 90% of the residues in the hepatopancreas were eliminated by 24 h. 3. In embryos high levels were noticed 6 h after administration and only 60% of the accumulated carbaryl was eliminated by 24 h. Carbaryl residues were observed in embryos even 1 week after administration.
