oa Journal of the Entomological Society of Southern Africa - Field tests of poison bait against hoppers of the red locust, 1935-36

Abstract

Early in the summer of 1935-36 the Government maize meal bait was used for the first time against hoppers of the brown locust in the north-western Cape Province and in the western Orange Free State. When the first red locust hoppers of the season hatched at Chakaskraal, in Natal, in December 1935, the writer tested the departmental bait against them, and found that excellent kills could be obtained on hoppers of the first and second instars in plant cane one foot in height. The bait was prepared according to the formula: maize meal 92 lbs., molasses 7 lbs. and arsenite of soda 1 lb.
