The honeybee (Apis mellifera) is likely to become the major model syst
em for resolving the genetic basis of advanced perceptual and behaviou
ral abilities of highly social insects because of the high level of kn
owledge regarding its physiology and social behaviour and its ease of
handling. Here we report for the first time genetic transformation of
honeybees by the production of chimeric larvae obtained by nuclear tra
nsplantation, identified by use of a genetic marker. Two chimeras expr
essed only the genotype of the donor indicating developmental totipote
ncy of nuclei up to the 11th cleavage mitosis. (C) 1995 Wiley-Liss, In
