Abstract

Lloyd (1959) reached two conclusions from his investigations into control techniques against the Red Locust. Firstly, that aerial spraying aided by the established ground scouting for hopper infestations (Scheepers, Eysell & Gunn, 1958) was superior to ground spraying. Secondly, that aerial scouting for hopper bands was impractical as it would be impossible to find and to destroy all the individual bands visible from the air when several outbreak areas contained large locust populations simultaneously. In 1960, ground scouting by control staff was stopped on the hypotheses that the aircraft pilots could find and destroy all locust aggregates, and that these aggregates contained all the locusts capable of forming swarms.
