A PROTOTYPE MOVING NET INSECT SAMPLER FOR USE IN THE PROJECT.
Abstract
In connection with the project on 'Studies of Airborne Insects in the Atmosphere' to test the theory on air dispersal of arthropods in the Pacific area, a prototype Moving Net Insect Sampler was designed and developed. This sampling device used to trap insects and other airborne organisms aboard ships travelling in the Pacific area, is designed to complete a twofold function: (1) a gauze strip drawn by the air intake at a constant rate provides time resolution data and allows the Scientists to determine when and where (if the cruise track of the ship is known) the specimens were trapped. (2) Once the trap is turned on it will operate continuously and automatically for a period of two to three weeks or until the net material is exhausted at which time it will shut itself off. Field tests undertaken thus far just off the coast of California resulted in sampling of specimens but not as effectively as expected considering the densities present in the area of operation. Modifications were made to improve the effectiveness of the trap. (Author)
