The distribution of the cotton pest Oxycarenus gossipinus in artificial temperature (16.5-40.5 degrees C) and relative humidity gradients (20-95% RH) was studied in an experimental chamber in the laboratory. Fifth-instar nymphs and adult females showed unimodal distribution to the hot end of the chamber to a temperature range of 29.0-34.0 degrees C and 31.5-37.0 degrees C, respectively. The adult males showed bimodal distribution, one to the cool end (19.0-24.0 degrees C), and the other to the hot end (31.5-37.0 degrees C).
