Pathogens represent critical agents of mortality for insects, yet their ecological impacts remain poorly understood in many natural systems. Developmental resistance (i.e., a reduction in disease susceptibility as hosts mature), along with age-related changes in ecology and behavior, are expected to give rise to variation in pathogen pressure across the host life cycle. However, the dynamics of pathogen infection across long larval periods such as those in diapausing insects are relatively unexplored.
We used field-collected Euphydryas phaeton caterpillars (Lepidoptera: Nymphalidae) to evaluate how interactions with a naturally occurring entomopathogen, Junonia coenia densovirus, varied across host development and diapause. We compared the frequency and severity of viral infection during three stages of the life cycle: post-diapause, pre-diapause, and diapause. Field-collected post-diapause caterpillars were reared until death before viral screening, while field-collected pre-diap..., , GENERAL INFORMATION
