OCCURRENCE OF THE OLD WORLD BEE SPECIES HYLAEUS HYALINATUS, ANTHIDIUM MANICATUM, A-OBLONGATUM, AND MEGACHILE SCULPTURALIS, AND THE NATIVE SPECIES COELIOXYS BANKSI, LASIOGLOSSUM MICHIGANENSE, AND L-ZOPHOPS IN ILLINOIS (HYMENOPTERA: APOIDEA: COLLETIDAE, HALICTIDAE, MEGACHILIDAE)

摘要

In rearing experiments, pupal weight was significantly higher when larvae fed on the native plant, regardless of the original host plant. There were no significant differences in the percentage of larvae successfully pupating and emerging as adults. Total development time was significantly shorter for caterpillars feeding on the native plant. Although the introduced plant S. varia is an adequate host plant, E. baptisiae preferred to feed on the native plant B. tinctoria, and also performed better on it. This implies that an increase in the number of B. tinctoria plants may increase the fitness of E. baptisiae, which may lead to a population increase and stabilization of the state population of E. baptisiae.
