PARALYZING ANIMAL POISONS.
Abstract
The following wasps were studied: Microbracon hebetor Say, Mellinus arvensis L., Philanthus triangulum F., Anoplius viaticus L. and Nemeritis canescens, Gravenhorst. Microbracon venom was shown to produce reversible paralysis in Galleria larvae, Philosamia larvae and Musca adults. Physiological experiments showed that this venom has no effect on nervous conduction in Philosamia, probably has no effect on the excitability of the muscles but does affect neuromuscular transmission. The active compound is probably not a protein. The venom can be separated in a number of compounds. However the active principle can not be eluted from the usual materials used in thin layer separation methods. Philanthus venom was shown to be active on the nerve - muscle preparation of Locusta. It probably affects neuromuscular transmission as well as nervous conduction. Mellinus arvensis L. can be reared in the laboratory. It is very likely that Philanthus trinagulum F. can also be cultured. Experiments were performed using a number of North Sea anemones and a number of test animals. Some indication was obtained that at least some of these anemones produced a paralyzing venom. However, probably due to inadequate techniques, the results obtained are not yet conclusive. (Author)
