An experimental design to estimate genetic parameters was based on the method developed by Oldroyd and Moran. This method was modified to eliminate within-colony environmental effects associated with the additive genetic variance. The estimated h2 values ranged from 0.17 ± 0.11 (maximum width of bulb of sting stylet and height of the valve of right lancet) to 0.74 ± 0.30 (length of the lancet).274-279engApis melliferaHeritabilityHoneybeesStingbee stingheritabilityhoneybeeArtigo10.1590/S0104-79301997000200003S0104-79301997000200003Acesso aberto2-s2.0-00308544377538556085505819
