Abstract

Some factors affecting bee venom extraction by electrical impulses directly from honey bee colonies were studied. Two experiments were conducted during the summer months to study the effect of defensive response degree, colony strength level, and season time of collection. Twenty-four carniolan hybrid honey bee colonies were used. The results revealed that defensive response was depended on the colony strength and season time of collection. When the number of stings par colony was determined, the stings number was related to the number of frames covered with bees. Bee venom amount which weakly extracted significantly differed during summer months (July and August). From the results of the variability of extracted venom amounts, the main peak of production was recorded during July month. Negative correlation coefficients were recorded between defensive response and collected bee venom from three strength levels from honey bee colonies

Highlights

Honey bee defensive behaviour is a complex trait that modified by many factors as honey bee race, weather factors, colony strength and health, time of the year and foraging activity (Collilns, 1979, 1981; Collins et al, 1984; Maritz et al, 1987; Woyke, 1992 and Hant et al, 1998)
The objective of the present work was to study the effect of aggressiveness response variability during summer months on venom quantities extracted by electrical impulses from honey bee colonies
Praimanry Evaluation of Honey Bee Colonies Defensive Response Degree: Data presented in tables (1&2) showed the means of defensive response rate of the three strength levels of honey bee colonies after two applications during June, 2019

In Egypt, Omar (1994) evaluated a new device for obtaining a high quantity of dry bee venom from honey bee colonies. Omar (2010) reported that there was a relationship between colony defensive behaviour and the quantity of dry bee venom collected by the electrical In Egypt, Omar (1994) evaluated a new device for obtaining a high quantity of dry bee venom from honey bee colonies. Omar (1997) recorded that venom extraction from honey bee colonies after queen removal or after artificial crowding and after honey extraction with one day increased venom quantity.
