This work was carried out at the apiary of the Agricultural Experimental Station, Faculty of Agriculture, Cairo University, Giza Governorate. Part I. Storing of honeybee mated queens for long period This study aimed to investigate some factors affecting stored mated honeybee queens weight and survival rate as well as post storage performance of these queens after 75 days of storage within queen-right colonies. Storing queens in numbers of 20, 30 and 40 had no significant effect on their weight. Mean weight of queen stored in excluder cages (EC) was significantly higher than those stored in screen mesh ones (SC). The mean weight of stored queens in the upper strip was higher than the mean of the lower one.Queens stored in peripheral and middle of holding frame did not differ significantly from each other. Concerning queens survival rate, the mean survival rate of 20 stored mated queens was the superior rank, while the survival rate of 30 and 40 stored mated queens came next with no significant differences between them. Queens stored in SC had more significant survival rate than those stored in EC. The upper strip had a higher survival rate than the lower one. Queens stored in the middle of holding frame showed significantly higher survival rate than those in the peripheral. Regarding post storage performance, no significant differences were detected between the brood areas produced by queens stored for 45 or 75 days in the 3 densities. Queens stored for 45 days and those in the upper level had a significantly higher brood production than those stored for 75 days and those stored in the lower level. Queens stored for 45 and 75 days had no significant differences in supersedure percentages either stored in the 3 densities, in 2 levels or in the 2 positions. Part II.
