Morphological characterization of cell death during the ovary differentiation in worker honey bee
(Elsevier B.V., 2002-01-01)
Cell death that occurs during ovary differentiation in the honeybee worker's larval development accounts for ovariole reabsorption. From a morphological standpoint, three modes of death were detected. Germinative cells in ...
Cell death in ovarioles causes permanent sterility in Frieseomelitta varia worker bees
Frieseomelitta varia worker bees do not lay eggs even when living in queenless colonies, a condition that favors ovary development and oviposition in the majority of highly social bees. The permanent sterility of these ...
Essential versus accessory aspects of cell death: recommendations of the NCCD 2015
(Nature Publishing Group, 2015-09-19)
Cells exposed to extreme physicochemical or mechanical stimuli die in an uncontrollable manner, as a result of their immediate structural breakdown. Such an unavoidable variant of cellular demise is generally referred to ...
Differentiation of the worker's ovary in Apis mellifera L. (Hymenoptera, Apidae) during life of the larvae
(Int Science Services/balaban Publishers, 2001-07-01)
The aim of the present study is to characterize the way worker and queen ovaries differentiate in, Apis mellifera, a species with trophic determination of female castes. A morphological study carried out with light and ...
Beekeeping practice: effects of Apis mellifera virgin queen management on ovary development
Newly emerged virgin queens are frequently imprisoned in cages either inside or outside of colonies before delivery to a new hive. Ovary integrity and proper functioning is the primary factor in a queen’s success as the ...
