In the progenies of 11 families, obtained at 20, 24 and 28 °C the wings showed four costal spots patterns. Pattern I was present in all three breeding temperatures with the highest frequency. Within families, the average length/width of wing ratio was significantly higher in males than females, while the variation by sex of this character was similar. Among the families, the temperature had variable influence on the sizes of wings and costal spots. Within the components of phenotypic variation, the breeding temperature had no significant detectable effect on the length of the wing and several of the analyzed characters; however, the proportion of the subcostal pale spot length over the length of the distal sector dark spot (SCP/DSD) was the most sensitive to temperature changes. The genetic contribution of the wing size and the measured characters length, as well as the effect of the families (origin) on the phenotypic variation, was significant for almost all the characters analyzed. The effect of the sexes on the phenotypic variation of the studied characters was significant only for some characters, while there were few significant interactions between the three factors analyzed (temperature, family and sex) with a low effect on the phenotypic variation.</p>}, number={1}, journal={Revista Colombiana de Entomología}, author={González Obando, Ranulfo and Cárdenas Henao , Heiber and Marín Londoño, Omar Alejandro}, year={2021}, month={Apr.}, pages={1–17} }
