“…In Langille et al (2016) we presented potential modeled populations for some of the more economically important berry producing counties and townships in the United States and Canada. Observed mean daily temperatures for a 20-year span (1993–2013) were obtained via the National Climatic Data Center (http://www.ncdc.noaa.gov/) for US locations and through Environment Canada (http://climate.weather.gc.ca/) for Canadian locations.…”

“…At this time there is no consideration for overwintering and as such the model is limited to single year simulations. Although empirical work continues to highlight the biological mechanisms and consequences of overwintering (Wallingford, Lee & Loeb, 2016; Wallingford & Loeb, 2016; Shearer et al, 2016; Stephens et al, 2015) it has not yet been included in the model (see discussion in Langille et al, 2016). As a result, these simulations do not account for inter-annual population differences due to winter survival rates and subsequently presume that all regions begin with the same starting population size each year, which does not specifically reflect migrations (immigration or emigration) due to environmental or anthropogenic factors.…”

“…Although multiple harvests per year were not included in these simulations, the model does account for the availability of wild hosts (Lee et al, 2015) by ensuring that the fruit quality sub model continues to have a positive, albeit minimized, effect on development post-harvest ( cf. Langille et al, 2016). Reproductive diapause is initiated when the simulated grid cell reached 10 daylight hours per day (latitude-dependent).…”

D. suzukii is a relatively recent and destructive pest species to the North American soft-skinned fruit industry. Understanding this species’ potential to shift in abundance and range due to changing climate is an important part of an effective mitigation and management strategy. We parameterized a temperature-driven D. suzukii population dynamics model using temperature data derived from several Global Circulation Models (CMIP5) with a range of relative concentration pathway (RCP) predictions. Mean consensus between the models suggest that without adaptation to both higher prolonged temperatures and higher short-term temperature events D. suzukii population levels are likely to drop in currently higher-risk regions. The potential drop in population is evident both as time progresses and as the severity of the RCP scenario increases. Some regions, particularly in northern latitudes, may experience increased populations due to milder winter and more developmentally-ideal summer conditions, but many of these regions are not currently known for soft-skinned fruit production and so the effects of this population increase may not have a significant impact.

“…The spotted‐wing Drosophila (SWD), Drosophila suzukii Matsumura, has proven to be highly invasive since its initial detection in new territories across the USA and Europe . The success of SWD predominantly stems from their ability to oviposit in healthy, ripening fruit rather than over‐ripe or rotting fruit .…”

BACKGROUND The unintentional introduction of Drosophila suzukii (Matsumura) from Asia has caused global economic losses in the soft and stone fruit industries. Pesticide use can have unintended negative impacts on natural enemies, disrupting attempts to incorporate integrated pest management programmes. Generalist predators could potentially act as biocontrol agents of D. suzukii. In this context, the predatory capabilities of the European earwig (Forficula auricularia) were investigated. RESULTS In semi‐field conditions, F. auricularia were effective at reducing the reproductive rate of D. suzukii in more densely populated enclosures. In controlled laboratory conditions, significant negative effects of earwigs were observed for both low (three breeding pairs) and high (six breeding pairs) D. suzukii densities. Both semi‐field and laboratory experiments revealed that F. auricularia predation on adult D. suzukii could not account for the subsequent reductions in population density. CONCLUSIONS Reductions in both larval and adult offspring in the presence of earwigs indicate an impact on D. suzukii via predation prior to metamorphosis or disruption of oviposition. Although F. auricularia may predate D. suzukii populations, its capacity to act as a biocontrol agent may be limited. However, results suggest that F. auricularia may be a more effective biocontrol agent earlier in the growing season. © 2019 Society of Chemical Industry

BackgroundDrosophila suzukii is a significant invasive pest that has caused high management costs and economic losses for blueberry growers in the United States. The status quo control strategy commonly used by growers is to apply pesticides proactively and frequently to reduce infestation. Recent studies have shown that the calendar‐based spraying strategy might be unsustainable in the long term, which makes reducing pesticide reliance a top priority for the berry industry. Incorporating pest monitoring into the control strategy could be an option to improve efficiency while reducing pesticide usage. This study assesses the economic implications of monitoring‐based control strategies to calendar‐based spraying control strategies for organic blueberry production in Oregon. We combine a Drosophila suzukii population model into the economic simulation framework, evaluate two monitoring methods (adult trapping and fruit sampling), and identify the profit‐maximizing control strategy under different scenarios.ResultsIn the baseline scenario, control strategies that incorporate fruit sampling exhibit the highest average profits. Although the status quo control strategy (spraying every three days) has higher average revenue than monitoring‐based strategies, the cost from the higher number of pesticide application offsets the returns.ConclusionThis study uses a novel bioeconomic simulation framework to show that incorporating fruit sampling can be a promising tool to reduce pesticide reliance while controlling for Drosophila suzukii infestation. These findings provide important information to monitoring‐based pest control strategies in organic berry production, and the assessment framework sheds light on the economics of pest management.This article is protected by copyright.
