Effect of Temperature, Humidity, Light, and Gravity on the Parasitoid Brachymeria intermedia1 , 3

Abstract
Females of the parasitoid Brachymeria intermedia (Nees) were studied in the laboratory for their response to various physical environmental factors. They preferred low humidities and temperatures between 26 and 29°C in gradients. Most activity was observed from mid-morning until late afternoon, with a peak between 1330 and 1530 hours. They were photopositive, inactive in the dark, and did not respond to gravity.
