Prionus laticollis (Drury, 1773) (Coleoptera: Cerambycidae), the broad necked root borer, is a known pest of numerous woody plant species. Larvae feed on and can severely damage roots and lower trunks, causing decline or structural weakness. It has been documented infesting commercial apple plantings in New York and New England, notably in recent years when infestations caused tree decline and death in an established orchard in Northport, New York. As with other Prionus species found in the U.S.A., males are attracted to all four isomers of 3,5-dimethyldodecanoic acid, the female-produced sex pheromone of the related species, P. californicus Motschulsky, 1845. We conducted field trials using a commercial mix of this pheromone to monitor occurrence, phenology and abundance of P. laticollis in several orchard and mixed hardwood habitats in New York from 2010–2015. Male beetles were readily captured in all locations using pitfall traps baited with a commercial synthetic pheromone blend of all possible isomers, with maximum seasonal totals of 112–145 beetles per site. The first beetles were captured from 19 June to 4 July, corresponding to 436–691 degree-days (base 10°C) from 1 January, depending on year and location. A 2012 lure comparison between the single-isomer natural pheromone and the four-isomer blend showed no significant differences in numbers of beetles captured. Beetle catch generally peaked within two weeks of initial flight each year, with most activity occurring throughout July. A distinct decrease in beetle numbers was noted at the Geneva location over the course of repeated annual trapping trials, possibly reflecting a negative impact on the local population.

Three Hololepta (Leionota) Marseul, 1853 (Coleoptera: Histeridae) species associated as predators of the agave weevil, Scyphophorus acupunctatus Gyllenhal, 1838 (Coleoptera: Dryophthoridae), were determined after field collections in agaves crops from Guerrero, Jalisco, and Morelos, Mexico. An illustrated taxonomic key is provided for easy recognition of Hololepta polita (Marseul, 1853), H. vicina LeConte, 1851, and H. yucateca (Marseul, 1853). Hololepta vicina is recorded for the first time from the Mexican states of Jalisco, and Guerrero.

The European shield bug species, Cyphostethus tristriatus (Fabricius, 1787), is recorded in Canada and North America for the first time. Notes on its ecology, distribution, and host plants, as well as field observations, are provided. An updated key to the Acanthosomatidae of Canada is presented.

A naturally-occurring infestation of mountain pine beetle, Dendroctonus ponderosae Hopkins, 1902 (Coleoptera: Curculionidae: Scolytinae), in the Shattuck Arboretum on the campus of the University of Idaho, Moscow, was found to be attacking non-native conifers. The arboretum had experienced a prior infestation in similar tree species in the late 1960s (Furniss & Schenk 1969). Infested trees were harvested, and an approximately 0.3-m section of each tree was cut from a height of 10 m on the bole and maintained under laboratory conditions. All insects that emerged from the bolts were collected and identified. In the current infestation, trees successfully attacked by mountain pine beetle included jack pine (Pinus banksiana Lamb.), Austrian pine (P. nigra L.), red pine (P. resinosa Sol. Ex Alton), pitch pine (P. rigida Mill.), eastern white pine (P. strobus L.), Scots pine (P. sylvestris L.), Norway spruce (Picea abies H. Karst.) and white spruce (P. glauca (Moench) Voss). A total of 777 mountain pine beetle were captured as they emerged from the bolts, and emergence densities of the beetle were similar across tree species. Insects from three orders, 15 families and 27 species emerged from the bolts. Species richness of the emerged insect assemblages were similar across tree species. Shortleaf pine had the largest number of emerged species of insects captured, followed by white spruce and eastern white pine.

Longhorn beetles (Coleoptera: Cerambycidae) feed during their larval stage on wood from recently dead or diseased trees and may have a wide variety of hosts. However, reports of larval hosts for Cerambycidae could be misinterpreted from field observations. The use of freshly cut branches to attract longhorn beetles is a method that provides reliable information about which hosts they use. This study reports new records of larval hosts of longhorn beetles in the tropical dry forest of San Andres de la Cal, Morelos, Mexico. In the study area, species of woody plants were sampled, from each of which sections of branches were cut and left exposed to local field conditions for two months to attract beetles. Branches were later collected and placed in emergence chambers. A total of 26 species of Cerambycidae emerged from the branches of 51 species of woody plants of the families Apocynaceae, Araliaceae, Burseraceae, Celastraceae, Convolvulaceae, Euphorbiaceae, Fabaceae, Juglandaceae, Malpighiaceae, Malvaceae, Moraceae, Oleaceae and Rubiaceae. For all 26 cerambycid species, we found previously unreported hosts, and for nine species, the hosts we report are the first recorded in the literature. The nine species whose host relationships have not been previously reported are: Euderces basimaculatus Giesbert & Chemsak 1997; E. pulcher (Bates, 1874); Elytroleptus grandis Linsley 1935; Neocompsa puncticollis asperula (Bates, 1885); Acanthoderes (Pardalisia) lacrymans (Thomson, 1865); Olenosus serrimanus Bates, 1872; Oreodera brailovskyi Chemsak & Noguera, 1993; O. copei McCarty, 2001 and Spliaenothecus picticornis Bates, 1880.
