Identification of sex attractants for 6 North American click beetle species in 4 tribes of the Elateridae.

We describe experiments that evaluated potential sex pheromone components for 6 North American click beetle species. In field trials in Illinois, South Carolina, North Carolina, and Virginia, male beetles of 6 species were strongly attracted to geranyl butyrate (Agriotes insanus Candèze), 5-methylhexyl (Z)-4-decenoate (Elater abruptus Say), 11-dodecenyl butyrate (Melanotus ignobilis Melsheimer), and limoniic acid (Gambrinus griseus [Palisot de Beauvois], G. rudis [Brown], and G.

A century of Illinois hover flies (Diptera: Syrphidae): museum and citizen science data reveal recent range expansions, contractions, and species of potential conservation significance.

Hover flies of the family Syrphidae are a highly diverse group of insects that exhibit varied life histories and provide numerous ecosystem services. Despite their importance, they are highly understudied, and many biological and distributional patterns remain unknown in regions like the midwestern United States. Data from specimens exist in regional insect collections but is largely undigitized and thus inaccessible to much of the scientific community.

Undocumented beetle diversity in the Southeastern United States: a case study of the minute clubbed beetles (Coleoptera: Monotomidae).

Studies of the saproxylic and predatory beetle family Monotomidae (Coleoptera: Cucujoidea) in the southeastern USA increased the known diversity for the family in the state of Georgia by one genus and nine species. Online records of Monotomidae from Georgia increased from 0 to 885. This work highlights the lack of basic diversity information about small beetles that inhabit wood, leaf litter, and other decaying plant matter in this region.

MonotomidGen - A matrix-based interactive key to the New World genera of Monotomidae (Coleoptera, Cucujoidea).

A matrix-based Lucid key is presented for the twelve genera of Monotomidae (Coleoptera: Cucujoidea) represented in the New World. A general overview is given for the features and technical specifications of an original interactive key for the identification of these genera. The list of terminal taxa included with the key provides a current summary of monotomid generic diversity for the Nearctic and Neotropical regions.

Antibothrus morimotoi Sasaji, an Old World cocoon-forming beetle (Coleoptera: Coccinelloidea: Bothrideridae) newly established in North America.

Antibothrus morimotoi Sasaji, a cocoon-forming beetle (Coccinelloidea: Bothrideridae) native to the Palearctic region, is newly reported from North America. In 2013 and 2015, several series of specimens were collected during an ongoing USDA/APHIS/PPQ exotic bark beetle survey in Franklin County, Ohio, U.S.

Attraction of Pollinators to Atemoya (Annona squamosa × Annona cherimola) in Puerto Rico Using Commercial Lures and Food Attractants.

Atemoya is a hybrid between Annona squamosa L. and Annona cherimola Miller (Annonaceae) and has potential to be an important fruit crop in tropical and subtropical areas. A major impediment to fruit production is low fruit set due to inadequate pollinator visits, typically, by beetles in the family Nitidulidae.
