Popis: | In 1964, 3 dispersal studies of Lygus hesperus Knight were conducted in California. On 3 different occasions, nearly a million adult Lygus bugs were collected in the field in a single day, tagged with a fluorescent pigment, and released the same day. Many workers contributed to several phases of the study and, therefore, summarized data on L. hesperus movements in alfalfa and cotton will be presented in another report. This paper describes the conversion of a self-propelled, high-clearance pesticide sprayer into an insect-collecting machine. Photographs and drawings of the machine are shown and explained. Methods of separating plant debris as well as separating different species by using nylon nets with mesh openings of appropriate size are discussed. The movements of a variety of pest and beneficial species can be studied with this collecting unit. The machine can be used also in other types of studies where mass numbers of insects are needed. |
