摘要：

A method is described for topical application of mobile liquids, whether volatile or not, to insects. The principle is that of the self-filling micro-pipette, the 'pipettes' being calibrated lengths of fine, thin-walled glass capillary tube; for use a micro-capillary tube is mounted in a special holder. The doses delivered were shown to be adequately reproducible for mean doses of 0.03 mu l. upwards. Precautions in use are : ( I) in filling the capillary, its tip is dipped into the reservoir of liquid no more deeply than is necessary: ( 2) the dose is applied to the insect in such a way that the liquid is carried rapidly away from the delivery tip; and ( 3) pressure for expulsion of the dose from the capillary is maintained until after the delivery tip is removed from the insect. A convenient apparatus for keeping a batch of insects under anaesthesia during their dosage is described.
