“…Both P. lucublandus and P. mutus are, however, generally described as carnivores (Larochelle and Larivière 2003), which may limit potential for these species to contribute to weed seed consumption. Pterostichus lucublandus and P. mutus do, however, feed on insect pests of lowbush blueberry, including the blueberry spanworm ( Itame argillacearia Packard) (Lepidoptera: Geometridae) and the blueberry flea beetle ( Altica sylvia Malloch) (Coleoptera: Chrysomelidae) (Renkema et al 2013, 2014).…”

“…Our experiments show that P. lucublandus and P. mutus do not consume significant amounts of hair fescue, red sorrel, or poverty oatgrass seeds, whereas H. rufipes readily feeds on common lowbush blueberry weed seeds and likely makes greater contributions to weed control through postdispersal weed seed consumption. All three carabid species coexist with and consume insect pests in lowbush blueberry fields (Cutler et al 2012, Renkema et al 2014). Therefore, maintaining populations of these carabid species in blueberry fields is desirable.…”

“…Viable overwintered seeds of many weeds can be found in these fields at the same time (Darbyshire and Cayouette 1989, Hoeg and Burgess 2000, White 2018). Although the predatory behavior of these species has been previously studied (Renkema et al 2013, 2014), little is known of the potential for P. lucublandus and P. mutus to consume seeds of weeds commonly found in blueberry fields. Others have reported that P .…”

Poecilus lucublandus (Say), Pterostichus mutus (Say), and Harpalus rufipes (De Geer) are abundant Carabidae in lowbush blueberry fields and may contribute to weed seed predation. We used laboratory no-choice test experiments to determine if these beetles feed on seeds of hair fescue (Festuca filiformis Pourr., Poales: Poaceae), poverty oatgrass (Danthonia spicata L.), and red sorrel (Rumex acetosella L., Caryophyllales: Polygonaceae), which are common weeds in lowbush blueberry (Vaccinium angustifolium Ait., Ericales: Ericaceae) fields. Poecilus lucublandus and P. mutus did not feed on seeds of the test weed species, but H. rufipes consumed on average over 30 seeds of each species. There are other weed seeds in blueberry fields that could be palatable to P. lucublandus and P. mutus, which warrants further research on the granivory potential of these important carabid species.

“…Beetles have important functions in agroecosystems as many predatory and a few parasitoid Carabidae and Staphylinidae prey on crop pests and provide an important ecosystem service (Symondson et al ., ; Collins et al ., ; Hemachandra et al ., ; Renkema et al ., ). These families also contain species that are primarily detritivorous, fungivorous or phytophagous (Good & Giller, ; Clough et al ., ), including seed‐eating carabids that contribute to weed control (Honek et al ., ).…”

1 Horticultural practices may impact invertebrates in agroecosystems, particularly natural enemies. Impacts can be better understood by grouping organisms functionally or using morphological traits in addition to taxonomic determinations. 2 We compared the effects of mulch type (compost, pine needles, unmulched) and weeding strategy (weeded, unweeded) on beetle (Coleoptera) communities in highbush blueberries, focusing on early-season captures that reflected overwintering habitat. 3 Beetle diversity was similar between plot types, although functional grouping revealed differences as a result of mulching but not weeding. Predatory and granivorous Carabidae were most abundant in unmulched plots, mycetophages were most abundant in pine needles, and saprophages were most abundant in compost. Predatory Staphylinidae were most diverse in compost plots, and the diversity of granivores was greatest in unmulched plots. 4 Carabid biomass was greater in unmulched than compost mulched plots partly as a result of larger beetle size. 5 Beetle communities in unmulched and pine needles mulched plots were more similar than those in compost mulched plots. 6 A combination of compost mulched and unmulched areas should benefit all predatory taxa, although mulch use for pest control will need to be evaluated within the context of other production goals.

Flea beetles are in the largest subfamily (Alticinae) of the family Chrysomelidae, or leaf beetles (Furth 1988). The name Altica is derived from the Greek word haltikos, which translates to good jumper. Although this group of insects are named flea beetles, this is not because the form of the body resembles fleas, but rather because they have strong hind legs allowing them to jump long distances like true fleas (Siphonaptera). Their great jumping skills are thought to have evolved as a mechanism to escape from predators.
