Resumo: | This study aimed to test whether the consumption of different host plants influences the size and shape of mandibles and associated muscles in oligophagic insects throughout ontogeny. Larvae of Heliconius erato phyllis (Lepidoptera: Nymphalidae) were reared on four species of passion vines (Passifloraceae) and had the size of their head caspules, mandibles and associated adductor muscles measured afterward. Corresponding effects on shape and potential allometries in mandibles were also evaluted using geometric morphometric analysis based on scanning electron micrographs. Growth in mandibular size was greater compared to that of associated adductor muscles. There was no host plant effect on the sizes of either mandibles or adductor muscles. However, the shapes of mandibles was significantly different among passion vine species used as larval food. Greater differences in shape associated with wider teeth were obtained for Passiflora suberosa, whose leaves are tougher compared to those of P. misera, P. caerulea, and P. actinia; and, among which there was no difference in manbilular shape. Thus, it was inferred that the larval stage of this Heliconius species is able to adjust its mandible shape according to the toughness of host plants; a phenotypic plasticity mechanism that can be supposed to have evolved in order to facilitate processing these kinds of leaves. |

Para esto se usaron larvas de Heliconius erato criadas en cuatro plantas hospederas naturales, a las que se les tomaron medidas de longitud de cápsula cefálica, tamaño mandibular y área del músculo aductor. Para detectar eventuales diferencias de forma mandibular se empleó microscopía electrónica y morfometria geométrica, y para posibles cambios alométricos se realizaron comparaciones entre curvas de crecimiento mandíbula vs. músculo aductor de los individuos criados en las cuatro plantas hospederas. Se encontró que no existen diferencias de tamaño entre las mandíbulas ni en músculos aductores de individuos criados en las diferentes plantas pero la forma mandibular fue significativamente diferente, mostrando una relación directa con la planta hospedera usada como alimento. Generalmente, la mandíbula creció proporcionalmente más que el músculo aductor, cuyo crecimiento fue estable. El cambio más significativo fue el alargamiento de los dientes incisivos en mandíbulas de larvas criadas con Passiflora suberosa. Se sugiere que esto se debe a que las hojas de esta especie poseen mayor dureza comparadas con las otras y que el desarrollar dientes largos facilitaría su corte y consumo.application/pdfengRevista Colombiana de Entomologia.
