Spatial distribution of infestations of Platynota stultana (Lepidoptera: Tortricidae) in California vineyards and a plan for sequential sampling
Environmental Entomology 12 (1), 60-65
Abstract: The spatial pattern of infestations of Platynota stultana in vineyards in the San Joaquin Valley of California was assessed. There was evidence for aggregation whether the sampling unit was a single vine, four vines, or eight vines. Based on the pattern for single vines, a sequential sampling plan for infestations of P. stultana in vineyards was formulated and tested.
