Abstract

In the initial study of the role of aquatic Hemiptera in the transport of aquatic micro-organisms from one habitat to another, relationships are shown between the micro-organisms in a known habitat with those washed from the insects collected from that habitat. One hundred and twelve aquatic hemipterans were collected and washed, the washings cultured and the microorganisms identified. Aseptic field collections were made from a bog pool on Whidby Island, Washington; the Lower Arboretum Pond, University of Washington, Seattle, and a small temporary pond near Lake Texoma, Oklahoma. The forty-two Corixidae (water-boatmen) yielded thirteen genera; the thirty-one Gerridae (water-striders) yielded forty-one genera; and the thirty-nine Notonectidae (back-swimmers) yielded thirty-nine genera of microorganisms. The importance of some aquatic Hemiptera in the transport of aquatic microorganisms has been demonstrated and from these data the Gerridae and Notonectidae are more important than the Corixidae.
