PHYSIOLOGICAL STUDIES ON HONEY BEES (APIS MELLIFERA L.) UNDER VARROA PARASITISM ( VARROA JACOBSONIOUD

Abstract

Physiological studies on honey bee (Apis mellifera L.) under Varroa parasitism (Varroa jacobsoni OudJ. The present study was carried out m the aptary yard of the

experimental station of Plant Protection Institute, Department of Apiculture, Ministry of Agriculture, Dokki, Giza during September, 1998 till end of September 2001. Using Camiolian hybrid. The present study was carried out to investigate the effect of the

infestation with Varroa mites on some characters of certain systems and glands of adult honey bees workers, drones and queens which effect activity and productivity of the honey bee host. The current study aiming to investigate the following purposes;

1- Effect of the parasite Varroa destructor (jacobsoni) on some morphological characters of certain systems and glands of honey bees (workers, drones and queens). 2- The histopathological effects of the mites on certain systems and glands of honey bees, workers, drones and queens. 3- The physiological effects of the parasite {Varroa destructor

(jacobsoni)} on some haemolymph components of honey bee workers. Part 1: Morophological studies

Morphological studies on the systems and glands of honey bee workers, drones and queens (Apis mellifera L.) under different degrees ofVarroa mites infestation Varroa destructor Oacobsoni).
