Development and evaluation of sequential sampling plans for Cryptolestes ferrungineus (Stephens) (Coleoptera: Cucujidae) infesting farm-stored wheat. Journal of Stored Products Research. 33(4):321-329.

Interpretive Summary: The development and evaluation of appropriate sampling plans are needed for cost-effective management of stored-product insects. Sequential sampling plans, which are based on a variable sample size, are generally more cost effective than plans based on a fixed sample size. For adults of the rusty grain beetle, Cryptolestes ferrugineus (Stephens), scientists at the USDA Agricultural Research Service, Center for Medical, Veterinary and Agricultural Entomology in Gainesville, Florida, developed sequential sampling plans based on complete counts and the presence/absence of insects in 0.5 kg grain samples removed with a trier from the top 1 m of wheat stored in farm bins. Insect count data were used to develop a sampling plan for estimating the density of C. ferrugineus with a fixed level of precision. The presence/absence data were used to develop a sampling plan for classifying the C. ferrugineus infestation level relative to an action threshold. The performance of these sampling plans was evaluated (validated) using independent data sets and an IBM-PC software program specifically designed to test the plans. This is the first paper illustrating the development and evaluation of sequential sampling plans for a stored-product insect.

Technical Abstract: The development and evaluation of appropriate sampling plans are needed for cost-effective management of stored-product insects.
