Temperature, especially body temperature, is a very important factor in the lives of animals. Body temperature may be raised or lowered by the transfer of heat directly by conduction, or indirectlyExpand
The Humidity Reactions of the Wood-louse, Porcellio scaber (Latreille)
1. Porcellio scaber exhibits hygrokinesis, being very active in dry air and almost motionless in nearly saturated air. With rising humidity a steadily increasing proportion of a batch of specimens isExpand
The Daily Rhythm of Activity of the Cockroach, Blatta Orientalis L : I. Aktograph Experiments, Especially in Relation to Light
1. In an aktograph at 25.5°C., at upwards of 75% relative humidity and with food present, the average locomotory activity of the cockroach per day does not depend on whether there is continuous lightExpand
The Biological Background of Locust Control
There is no single species properly named "locust," for intensely migra­ tory and swarming species, like the desert locust of the Bible, shade off into sedentary and nonswarming grasshoppers, some ofExpand

The Temperature And Humidity Relations Of The Cockroach: V. Humidity Preference
1. In a diffusion gradient of humidity at uniform temperature, some cockroaches (Blatta orientalis, L.) show a tendency to spend more time in the drier region. Other individuals appear to beExpand
