“…Additionally, behavioral control methods, such as mating disruption, have been evaluated (Figure 3), with newer technologies allowing for better identification of pheromones of cranberry insect pests (Rodriguez-Saona et al, 2020a). Furthermore, there has been increasing research on biological and natural control, particularly on the use of entomopathogenic nematodes for soil insect pests (Hayes et al, 1999;Koppenhöfer et al, 2008;Ye et al, 2018;Foye and Steffan, 2019).…”

“…The most popular predators used in cranberry agriculture are entomopathogenic nematodes that can be sprayed to control root pests, such as Steinernema carpocapsae Weiser (Rhabditida: Steinernematidae) for the control of O. sulcatus (Hayes et al, 1999), Heterorhabditis bacteriophora Poinar (Rhabditida: Heterorhabditidae) for the cranberry rootworm, Rhabdopterus picipes Oliver (Coleoptera: Chrysomelidae) (Polavarapu et al, 2000), and Steinernema scarabaei Stock and Koppenhöfer (Rhabditida: Steinernematidae) for P. georgiana (Koppenhöfer et al, 2008). The recently discovered nematode Oscheius onirici Torrini et al (Rhabditida: Rhabditidae) can kill S. sulfureana (Ye et al, 2018;Foye and Steffan, 2019) and A. vaccinii (Ye et al, 2018), as well as suppress S. frontalis (Foye and Steffan, 2019). Other predators that are commonly present in cranberry ecosystems include spiders (Bardwell and Averill, 1996;van Zoeren et al, 2018;de Lange et al, 2019b), staphylinid beetles (Haase-Statz, 1997, coccinellid beetles (Rodriguez-Saona et al, 2011a;Salamanca et al, 2017;de Lange et al, 2019b;Salamanca et al, 2019), chrysopid lacewings (Rodriguez-Saona et al, 2011a;de Lange et al, 2019b;Salamanca et al, 2019), and syrphid flies (Rodriguez-Saona et al, 2011a;Salamanca et al, 2017;de Lange et al, 2019b;Rodriguez-Saona et al, 2020c).…”

Over the past three decades, an increasing body of entomological research has been published on integrated pest management (IPM) in cranberries (Vaccinium macrocarpon Aiton). However, no paper has been published that synthesizes the existing literature. This paper fills this gap by analyzing 139 peer- and editor-reviewed articles that were data driven and had direct relevance to the subject of insect pests or insect pest management of V. macrocarpon. Results show that the top three studied insect pests of cranberries have been Sparganothis fruitworm (Sparganothis sulfureana Clemens), blackheaded fireworm (Rhopobota naevana Hübner), and cranberry fruitworm (Acrobasis vaccinii Riley). The regions with the most published entomological papers on cranberry IPM research have been New Jersey, Massachusetts, and Wisconsin in the United States, followed by British Columbia in Canada. Among IPM tactics, published research on chemical control, as well as on host-plant resistance, has increased likely due to recent advances on newer, reduced-risk insecticides and high-yielding cultivars; while published research focusing on behavioral control has declined likely due to the cost of these tactics. There are no consistent trends in published research on natural and biological control or cultural control. These historical research trends are important when considering regulatory changes on insecticide use, such as the Food Quality Protection Act of 1996 in the United States, which resulted in the banning and restrictions of certain broad-spectrum insecticides. As more insecticides are banned or restricted and global and organic cranberry production increases, we anticipate further advances in research related to sustainable IPM tactics.

The spotted-wing drosophila, Drosophila suzukii Matsumura, is an exotic species in North America and represents a major threat to fruit production. Efforts to manage D. suzukii have focused primarily on insecticides, but such controls may, at times, be unreliable, given that D. suzukii larvae are often ensconced within fruit. The fruit interior, however, may represent suitable foraging substrates for carnivorous/entomopathogenic nematodes. In preliminary trials, a rare nematode species, Oscheius onirici Torrini et al., was shown to be highly virulent against D. suzukii when the nematodes were applied directly to fly larvae. To address the more important question of whether this nematode would be as virulent when applied to fruit, we set up assays in which blueberries were infested with D. suzukii larvae and then sprayed with O. onirici infective juveniles (IJs). Across two laboratory trials, O. onirici IJs suppressed D. suzukii puparia by 78.2%. Oscheius onirici IJs were able to search effectively within fruit substrates, find the fly larvae therein, and kill the flies before they could pupariate. Oscheius onirici, therefore, may represent a viable new bio-control agent for D. suzukii management and should be field-tested across a broader diversity of cropping systems.
