K. Naumann et Mb. Isman, TOXICITY OF A NEEM (AZADIRACHTA-INDICA JUSS,A.) INSECTICIDE TO LARVALHONEY-BEES, American bee journal, 136(7), 1996, pp. 518-520
The effects of a neem-based insecticide on larval honey bees, Apis mel
lifera L., was examined by applying the insecticide to larvae in their
cells. The LD50 values are higher than those reported for most other
insect species, The potential for the transport of neem from sprayed c
rops to the nest via contaminated nectar and pollen was assessed by me
asuring the rate of translocation of the main A.I., azadirachtin, from
leaf surfaces to the nectar or pollen of blossoming canola, Brassica
campestris L. No such translocation was detected.
