A model for determining the interactions between some honey bee (Apis mellifera L.) genotypes and different grooming times in terms of aggression

open access: yesTurkish Journal of Agriculture: Food Science and Technology, 2021
In honey bee (Apis mellifera L.), aggression and aggressive behavior occur due to many reasons and the most important one is the genotype. However, regardless of genotype, a bee colony can have different levels of aggression at different times.

Evaluation of Apis mellifera Carniolan and Africanized honey bees in royal jelly production [PDF]

open access: yesBrazilian Archives of Biology and Technology, 2004
Investigations were carried out to evaluate Africanized and Carniolan hybrid Apis mellifera honeybees in royal jelly production. Ten colonies were randomly collected in nature and housed in Langstroth beehives. Each hive was having two nuclei with five frames. In superior nucleus frame was containing 28 acrylic cups in two bars.
