A Review Of Hippeutister Reichensperger With New Species From California And Costa Rica (Coleoptera: Histeridae: Hetaeriinae), Michael S. Caterino, Alexey K. Tishechkin
Michael S Caterino
The myrmecophilous genus Hippeutister Reichensperger, 1935, contains six species, known from scattered localities in North, Central and South America. Two of these, H. californicus n. sp. and H. solisi n. sp. are newly described herein. The other four are H. manicatus (Lewis) (=H. solenopsidis Reichensperger, syn. nov.), H. plaumanni Reichensperger, H. castaneus (Lewis), and H. amabilis (Wenzel). The genus is likely monophyletic, and is easily recognized by the presence of a very broad prosternal keel, which is deeply triangularly incised at the base. Species of Hippeutister are unusual among hetaeriine Histeridae in their occurrence in the nests of fire ants …

Sequential Sampling Plans For The Red Sunflower Seed Weevil (Coleoptera: Curculionidae) In Oilseed Sunflower, Chengwang Peng, Gary J. Brewer
Sequential Sampling Plans For The Red Sunflower Seed Weevil (Coleoptera: Curculionidae) In Oilseed Sunflower, Chengwang Peng, Gary J. Brewer
Gary J. Brewer
Decision making on control of the red sunflower seed weevil, Smicronyx fulvus LeConte, requires a reliable and efficient method for classifying the pest population. The objective of this study was to develop sequential sampling plans for red sunflower seed weevil control in oilseed sunflower. Sequential classification sampling plans were developed from Wald's sequential probability ratio test (SPRT) by using a negative binomial distribution. Operating characteristic and average sample number functions were computed for a range of k values. Two sampling plans were developed for the economic thresholds of six and eight weevils per sunflower head, based on a k value …

Distribution, Ecology, And Population Dynamics Of The American Burying Beetle [Nicrophorus Americanus Olivier (Coleoptera, Silphidae)] In South-Central Nebraska, Usa, Jon C. Bedick, Brett C. Ratcliffe, W. Wyatt Hoback, Leon G. Higley
Brett C. Ratcliffe
The endangered American burying beetle, Nicrophorus americanus Olivier, was previously widespread throughout eastern North America. In the past century numbers of this beetle have drastically declined and currently remnant populations are known from only six states despite intensive surveying efforts conducted for the last nine years. Efforts aimed at discovering and managing remnant populations have been generally limited by a lack of knowledge concerning N. americanus biology. We used baited pitfall traps to define the range of the Gothenburg, Nebraska, population of N. americanus. Using mark-recapture techniques, we estimate that the annual Gothenburg population consists of more than one thousand …
