Extract

A few years ago a paper appeared in this Bulletin (Buxton, 1931) describing methods of controlling and measuring humidity. Since that paper was written, we have evolved a number of improvements which tend to make the methods easier in practice, though none of them are novel in principle. It is now known that humidity has diverse and unpredictable effects on many insects. In experimental work it is advisable that humidity should always be measured and controlled even if it is not a factor in the experiment. Moreover, workers should state what method of measurement or control they have adopted.
