Abstract:

A helicopter-mounted isokinetic aerial insect sampler was designed and constructed to study the distribution and density of weakly flying insects in the lower atmosphere. The volume of air sampled can be determined accurately by maintaining a nondivergent airflow into the sampler chamber. The velocity of the airstream is reduced inside the collection chamber so that small, delicate insects are usually alive after capture. The mean and variance of the airspeed, air temperature, and pressure level during each sample period of the collection flight are automatically recorded. Accurate documentation of the aerial densities of insects are obtained by the isokinetic aerial insect sampler at flexible but discrete levels within the lower atmosphere.
