Extract

Various methods for recording the activity of insects have been reported (e.g. Park, 1935, 1937; Gunn, 1940; Hammond, 1953). In this type of investigation, three characteristics are desired in the method: a) the apparatus should be sufficiently sensitive for recording small movements in small insects; b) the portion of the apparatus in immediate contact with the insect should permit easy subjection of the organism to various environmental conditions; c) the apparatus should permit rapid and easy accumulation of data from a number of insects. Two methods have been developed in the present laboratory in attempts to meet as far as possible these desirable qualifications.
