Abstract

A preliminary study was conducted to determine if the rove beetle, Paederus littorarius Grav., would exhibit a feeding preference for the eggs of the pyralid moth, Chrysoteuchia topiaria Zeller, a pest in Wisconsin cran­berry bogs. Individuals were offered a choice of C. topiaria eggs or Drosophila sp. adults for four days. Total number of prey items eaten was converted to weight using a multiplier based on the mean weight of 20 individuals of each prey item, respectively. A significant preference for Drosophila adults was observed in the preference trial; however as many as 24 C. topiaria eggs in addition to Drosophila offerings were consumed by P. littorarius individuals within a 24 h period. Additionally, laboratory and field observations suggests P. littorarius is a polyphagous predator.
