TL;DR: The type and degree of damage to adult workers of Apis mellifera from infestation with the parasitic mite Varroa jacobsoni during development was investigated and mean weights of infested bees upon emergence as adults were 6·3% to 25% less than for healthy bees.

TL;DR: Two new morphometric techniques are tested on samples consisting of digital images of five worker forewings per colony, giving more than 99% correct identifications of Africanized honey bees, inexpensive, fast and precise.

TL;DR: The ectoparasitic honey bee mite Varroa jacobsoni, first described by OUDEMANS (1904) from the Asian honey bee Apis cerana in Java, is distributed throughout Asia and has extended its range from Asia to Eastern and Western Europe and Northern Africa and much of South America.

TL;DR: The morphometric and genetic profiles of an Africanized honey bee population collected near where the original African swarms escaped, after 34 years of Africanization, are examined, indicating selective pressure replacing the European with the African genome in this tropical region.

TL;DR: Ces resultats montrent que des mesures d'une petite partie du corps de l'abeille sont suffisantes pour discriminer les sous-especes.
