Miniature stingless bee queens have been studied concerning frequency distribution, production and egg laying performance. This study aimed to investigate size variation in eggs laid by Plebeia remota (Holmberg) queens and whether it is due to differences in queen size or colony conditions. A sample of 10 queens (8 of typical size and 2 miniature) was measured morphometrically (head width, interorbital distance, and intertegular distance) as well the eggs they laid (length, width and volume). Initially, eggs were analyzed when laid by queens in their own colonies. Significant differences were found for length, width and volume of eggs considering the total group of queens or both queen morphotypes. However, no significant correlations were found between queen size and egg size. Afterwards, two experiments were performed to evaluate the influence of colony conditions on egg size. Firstly, we shifted the queens from their original colonies (i.e., a typical queen was placed into a miniature queen colony, and vice-versa). Secondly, they were put into another colony (both types of queens, one each time, were placed on a third colony, a ?host colony?). In all situations, both queen morphotypes laid eggs of similar or different sizes than before, often with significant differences. The results indicate that variation in egg size is due to conditions imposed to queens in the colony (e.g. queen feeding status, number of cells available to be oviposited), and not due to variation in queen body size.

Nosso objetivo foi avaliar a efetividade deste método em atingir progresso genético, mantendo a variabilidade genética e aumentando o potencial da população para a extração de linhagens superiores quanto à produtividade, altura de planta e duração do ciclo até a floração. A população de arroz irrigado utilizada neste trabalho foi a CNA12S, a qual tem ampla base genética e já foi submetida a três ciclos de seleção recorrente. |
