Untersuchungen über die Wirkung der Insektentötenden PilzeBeauveria bassiana (Bals. Vuill.) undMetarrhizium anisopliae (Metsch.) Sorok. auf Warmblütler
SummaryThe muscardine-fungi are nor toxic neither pathogen for man and warmblooded animals. Reactions of sensitive persons working with spores of this fungi are not of general but of allergic nature. Against such allergic reactions it is possible to protect by breath protection, dress with long sleeves and gloves.
AN APPARATUS FOR DETERMINING THE EFFECTS OF TEMPERATURE AND HUMIDITY ON GERMINATION OF FUNGOUS SPORES
An apparatus is described by which fungous spores can be uniformly distributed on microscope slides. A procedure is outlined whereby Petri dishes can be converted into airtight humidity chambers, the humidity of which can be readily checked. It was found that above 94% relative humidity maximum germination among Beauveria bassiana spores occurs at 28 °C.
OBNOXIOUS PESTS—SUGGESTIONS RELATIVE TO THEIR DESTRUCTION
The question how to check the ravages of obnoxious insects is a very important one, and I am very often asked for advice in special cases. While occupied with a close examination of the proposed remedies and looking through a large number of scientific tracts, some of them fell into my hands and induced me to study them again. The present communication is the result of those studies.
