European honey bee (Apis mellifera L.) (Hymenoptera: Apidae) colonies kept at high elevations in Costa Rica tested for African DNA markers






Bee Science 2(1): 25-32

European honey bee (Apis mellifera L.) (Hymenoptera: Apidae) colonies kept at high elevations in Costa Rica tested for African DNA markers

A small apiary (E) of European honey bees at an altitude of 2200 m was thought to have remained free from introgression of African paternal genes. In order to check this, samples of uncapped worker larvae were taken from the 7 surviving E colonies, and also from 3 African (A) colonies at an altitude of 700 m; all samples were analysed for 2 types of DNA.

Queens were vibrated approximately twice as often whe...

Drones developed from eggs laid by previously nonreproductive workers. First...

Yoshida, T., 1995: Comparative studies on the mating system of the Japanese honey bee, Apis cerana japonica Radoszkowski, and the European honey bee, Apis mellifera L. (Hymenoptera: Apidae). Mating flight times were observed in both species. A. cerana queens started flying at 13.15 h and the last queens with mating signs returned between 14.45 h and 16.35 h. Drones flew from 13.15 h to 16.30 h with a 30-min peak from 15.00 h. For A. m...

The behavior of two swarming and three absconding queens of the African honey bee was examined in the Okavango River Delta, Botswana. Compared to the swarming queens, the absconding queens (1) spent significantly less time active per observation i...
