Neither the nuclear nor the mitochondrial data corroborated subspecies groupings. Copyright © sensagent: However, these glomeruli were intermingled with glomeruli responding to ,for example, plant-related compounds, i. However, the exact relationship between growth rate and temperature varies among populations in many species. It has been suggested that phenotypic plasticity is a major factor in the diversification of life, and that variation in host range in phytophagous insects is a good model for investigating this claim. Indeed, the mechanism of sexual reproduction occurred very early in evolution, for it is seen today even in bacteria. The photoperiod varies with latitude and has led to local adaptation in the photoperiodic induction of diapause in many insects.

Results do not support this hypothesis, suggesting that the specialist and generalist traits have evolved more than once independently.

In support of the 'plasticity scenario', phylogenetic traces of a long-lasting stage with some potential to feed on more than one host-plant clade can still be seen, despite the ancient age of the colonizations. This circumstance allows for a potential mother-offspring conflict, resulting in the female maximizing her fecundity at the expense of larval performance on suboptimal hosts. In the present study, we investigate diapause development under a range of durations weeks spent at different temperatures -2 to 10 degrees C in the pupal diapausing butterfly Pieris napi Linnaeus Lepidoptera: Several factors might have been important for the diversification of Satyrini: There is a growing awareness that ecological factors can lead to rapid diversification and, as one of the most prominent features of most insect-plant interactions, specialization onto a diverse resource has often been assumed to be the main process behind this diversification.
