Multiple Mating Queen Bees Help Maintain Genetic Diversity in Apis dorsata

E-mail Print PDF

Chennai, April 17, 2012: Mattila and other researchers have recently shown that colonies with genetically diverse populations of workers, a result of the highly promiscuous mating behavior of queens, are healthier than colonies with genetically uniform worker bee populations (see news dated March 14, 2012 in this site). A latest study* on the giant honey bee (Apis dorsata) colonies in China published on April 12, 2012 in the journal PLoS ONE demonstrates a similar trend in this bee species.

Alternative Model for the Origin and Evolution of Eusociality Suggested

Chennai, December 27, 2011: Prof. James Hunt, presently at the North Carolina State University, Raleigh, USA, writing about his research interests (see here), says: '... the worker and gyne castes among the brood of a Polistes colony are based on the underlying physiology of non-diapause and diapause as is found widely among insects. ... Polistes offspring do not "choose" to work in order to maximize their inclusive fitness. Instead they are products of their ontogeny combined with the social context into which they emerge, and their behaviors have the consequence of enhancing the fitness of the colony queen that laid the eggs that now are the larvae they care for. Inclusive fitness had nothing whatsoever to do with the origin of such sociality.'

Integrative Taxonomy Helps Discover New Species of Sweat Bees From North America

E-mail Print PDF

Chennai, November 25, 2011: Integrative taxonomic approach utilizing the DNA barcode region of cytochrome c oxidase subunit 1 in conjunction with traditional morphological approaches is increasingly used to identify insect species. Jason Gibbs of the York University, Toronto, Canada used this approach to differentiate species within Lasioglossum (Dialictus) tegulare group1. He could identify five distinct species in this group, earlier recognized as a single species.
