Relative accuracy of sweep net sampling was compared with D-vac (D-vac, Riverside, Calif.) and absolute sampling methods for determining population densities of pea aphid, Acyrthosiphon pisum (Harris), Nabi. s spp., Hippodamia spp., and Chrysopa spp. in lentils ( Lens culinaris Medikus). Relative effects of the a biotic environment, predators, and time of sampling on population estimates also were determined during 2 yr. Original counts, area, and volume adjustments were used to evaluate… CONTINUE READING
