The Bionomics of some Tree-hole Mosquitos

Abstract

1. 138 larvae of Anopheles, Finlaya and Orthopodomyia, collected from three tree-holes described in Part I, were dissected and their contents examined.2. Small algae, a few animals, bacteria and considerable quantities of rotting vegetation were found in them.3. The algal and animal food seems to be insufficient for the anabolic processes of the larvae.4. It is possible that bacteria may play some part in their nutrition, especially of Orthopodomyia.5. It is also suggested that the larvae are able to utilise any food constituents present in the vegetable debris.I wish to thank Dr. P. A. Buxton for the interest he has shown during the progress of this work, and Professor F. E. Fritsch for help in identification of the algal species.
