The number of Ovarioles in 111 queens (Apis mellifera ligustica) was highly significantly correlated with their weight at emergence, at 2 h after emergence, and at 24 h after emergence. The weight of queens at emergence was highly significantly correlated with their weight at the start of oviposition, in the period of oviposition, and in the period of egg-laying cessation respectively. In 39 queens the number of ovarioles was positively correlated with their weight at emergence, but was not significantly correlated with their weight at 2 h after emergence, at the start of oviposition, in the period of egg-laying and in the period of egg-laying cessation. The relationship between the weight of 8 queens at emergence and the number of eggs they laid was significant. It is suggested that the weight of queens at emergence might be a useful index for selecting queens with high fecundity.
