Inbreeding and building up small populations of stingless bees (Hymenoptera, Apidae)
Provedor de dados: Zoologia
Autores: Nogueira-Neto,Paulo.
A study of the viability of small populations of Hymenoptera is a matter of importance to gain a better zoological, ethological, genetical and ecological knowledge of these insects, and for conservation purposes, mainly because of the consequences to the survival of colonies of many species of bees, wasps, and ants. Based on the Whiting (1943) principle, Kerr &amp;amp; Vencovski (1982) presented a hypothesis that states that viable populations of stingless bees (Meliponini) should have at least 40 colonies to survive. This number was later extended to 44 colonies by Kerr (1985). This would be necessary to avoid any substantial amount of homozygosis in the pair of chromosomic sexual loci, by keeping at least six different sexual gene alleles in a...
