Abstract

Under laboratory conditions, the development from egg to adult of P. wellcomei takes an average of 42 days. The larval tages are similar to those of P. arthuri, described by barretto (1941), but can be distinguished from this species by the ratio of the first to second antennal segment, by the form of the lateral head seate and prothoracic dorsolateral setae. The pupal stage of P. wellcomei is characterized by a trifid pre-alar seta and simple spine-like thoracic and abdominal setae.Em condições de laboratório, o desenvolvimento dos ovos à forma adulta do P. wellcomei leva, em média, 42 dias. Os estádios larvários são semelhantes áqueles do P. arthuri, descrito por barretto, (1941), mas podem ser distinguidos deste último pelo tamanho do primeiro e segundo segmentos antenais e pela forma das cerdas laterais da cabeça e dorso-lateral do protórax. O estádio pupal do P. wellcomei é caracterizado por uma cerda pré-alar trifurcada e por simples cerdas, torácica e abdominal, semelhantes a um espinho.
