Two blacklight traps were operated in a non-agricultural setting in Cary, North Carolina, USA, from spring through fall in 2004 and 2005 and all Coccinellidae collected and identified. More than 1300 lady beetles were collected in each of the two years, with Harmonia axyridis dominant (> 98%) and collected consistently over the course of the trapping period. Although other coccinellid species were observed in the vicinity of the traps during photophase, their appearance in blacklight traps was negligible. Harmonia axyridis exhibited a distinct diel periodicity in appearance at the traps, beginning approximately an hour after sunset and ending about midnight. Sunrise and sunset collections from flight interference and sticky traps in a local alfalfa field suggest that H. axyridis may be more flight active during the scotophase than Coleomegilla maculata, Hippodamia convergens, and Coccinella septempunctata. This study supports the suggestion that blacklight traps give a biased depiction of coccinellid species composition in a given area, and indicates that seasonal and circadian thresholds for flight activity, phototaxis, or both in H. axyridis may diverge from those in most other Coccinellidae.

Detection of low-level infestations of pest Buprestidae such as emerald ash borer is crucial for their effective management, but the efficiency of trapping techniques varies. In the present study, we compare two nondestructive methods for monitoring metallic wood-boring beetles. Buprestidae captured by the wasp Cerceris fumipennis Say (Hymenoptera: Crabronidae) were compared with those captured by USDA-APHIS-PPQ standard issue purple prism traps (PPTs) at three sites in North Carolina, U.S.A. At each site, four PPTs were hung on trees at the edge of a known C. fumipennis nest aggregation, and changed at 5.5-7.0-week intervals. Buprestids were collected from hunting wasps once a week during their 5-6-week activity period. A total of 28 buprestids (seven species) were caught by traps, whereas 267 buprestids (35 species) were collected from C. fumipennis. Of buprestids captured by PPTs, 22 were caught during the pre-flight period of C. fumipennis, six during their flight period and none during the post-flight period. One species of Agrilus Curtis was captured by PPTs, while six Agrilus species were captured by wasps. Of the 38 identified buprestid species taken at these sites, only four were recovered at a given location by both methods. Although a standardized comparison of the two techniques is not feasible, C. fumipennis captured a greater number and diversity of Buprestidae than did PPTs. A combination of both techniques may provide the most complete temporal coverage of buprestid activity in a given area, provided that a nesting aggregation of C. fumipennis is available. © 2015 The Royal Entomological Society.

Distribution records and seasonal flight activity information for metallic woodboring beetle (Coleoptera: Buprestidae) species have not been compiled for North Carolina and Tennessee. Institutional, research, and private collections in North Carolina and Tennessee were reviewed to provide seasonal activity data of 5 subfamilies of buprestid beetle species. Label information was checked for 15,217 specimens of 135 species collected between 1901 and 2013 (North Carolina) and between 1934 and 2013 (Tennessee). These collections provided data on adult seasonal activity and county records for 121 species (4,467 specimens) and 105 species (10,750 specimens) from North Carolina and Tennessee, respectively. Two species, Agrilus carpini Knull and A. pensus Horn, are reported as New State Records for North Carolina. The data reveal key geographic areas in both states where few to no collections have been made, highlighting opportunities to validate species distributions and locations where future collecting efforts can be matched with the occurrence of larval and adult host plant resources. Seasonal activity records will inform future biosurveillance efforts for invasive and endemic pests and facilitate predictions of buprestid species that are likely to be active within the hunting flight season of Cerceris fumipennis (Say) (Hymenoptera: Crabronidae) wasps. Activity periods of the buprestids also can focus the management of selected economic pest species to times of the year when treatment efforts, particularly through use of contact insecticides, are likely to be most effective.

Surveys of baseball and softball diamonds for nests of the ground-nesting wasp Cerceris fumipennis were conducted between 2008 and 2011 in three states: Connecticut, Maine and North Carolina. A total of 1398 ball fields were surveyed, with roughly 22 of these positive for nests of the wasp. Nine percent of the fields had ≥15 nests and were therefore of practical use in a biosurveillance program for buprestid pests. Connecticut had the highest proportion of both positive fields and of fields useful for biosurveillance. Among fields with any number of nests, the two northern states had a significantly higher proportion with ≥15 nests. Characteristics of ball diamonds associated with the presence of C. fumipennis are discussed, and the advantages and disadvantages of using ball diamonds in a biosurveillance program addressed. © 2012 Kansas Entomological Society.
