摘要
Jamaica's three species of social wasps were found nesting together in a suburban area. Their nests gave evidence of markedly different parasitoid loads in the sequence Polistes crinitus > P. dorsalis > P. major. Based on larval and pupal silk remains, the moth Chalcoela pegasalis appears to be the main nest parasitoid at this locality. Despite widely different parasitoid loads, the estimated per-nest production of adults was similar among the three species. This suggests a trade-off between investment in anti-parasitoid tactics and in other brood-care activities.
