“…The D. suzukii colonies used for this study were maintained in the same manner as described in Emiljanowicz et al (2014). Controlled experiments on temperature-dependent development, fecundity, and mortality were carried out using a laboratory colony of flies that originated from infested fruit from a farm in Southern Ontario (mean daily winter averages ≈ −6 • C).…”

“…To rear flies that were to be used in the overwintering experiment, one controlled growth chamber was set to 15 • C, 25% RH, and a photoperiod of 10:14 (L:D) h (short photoperiod conditions), and one controlled growth chamber was set to 15C, 25% RH, and a photoperiod of 15:9 (L:D) h (long photoperiod conditions). Diet dishes (as described in Emiljanowicz et al 2014) that were left in the colony cages for 2 d were transferred to either the short or long photoperiod growth chamber and left to incubate in those conditions until adult eclosion (30 d).…”

“…The diet lids of the mating chambers were replaced every second day over this period, and egg counts were performed on these diet lids. To determine viability of these eggs, the diet from the lid was transferred to a large petri dish filled with fresh diet (similar to the method described in Emiljanowicz et al 2014 to determine sex ratio). After the 6-d period, a total of three diet lids had been transferred to the original petri dish.…”

“…A recent laboratory study of the life history of D. suzukii found that this species has a relatively high fecundity and long life span. Emiljanowicz et al (2014) found that D. suzukii had an average lifetime egg production of 636, a daily egg production of 5.7, an egg-to-adult development time of 12.8 d, and an average life span of 86 d. However, precise details of how such life history traits are altered by temperature are just beginning to be explored.…”

The spotted-wing drosophila (Drosophila suzukii Matsumura) is an invasive species of Asian origin that is now widely distributed in North America and Europe. Because of the female's serrated ovipositor, eggs are laid in preharvest fruit, causing large economic losses in cultivated berries and stone fruit. Modeling D. suzukii population dynamics and potential distribution will require information on its thermal tolerance. Large summer populations have been found in regions with severe winter conditions, though little is known about responses to prolonged low-temperature exposure. We used controlled chambers to examine D. suzukii fecundity, development rate, and mortality across a range of temperatures encompassing the upper and lower thresholds (5-35 • C). Optimal temperatures (T opt ) were found to be 28.2 • C for the development of the egg-to-adult stage, and 22.9 • C for reproductive output. No adult eclosion occurred below 8.1 • C (T lower ) or above 30.9 • C (T upper ). We also investigated survival outcomes following prolonged (42-d) low-temperature exposure to a simulated cold winter (−5, −3, −1, 1, 3, and 5 • C). Adult survival was dependent on temperature, with a mean LT 50 of 4.9 • C. There were no effects of sex, mating status, geographic strain, and photoperiod preexposure on overwintering survival. Thirty-eight percent of females that were mated prior, but not after, prolonged low-temperature exposure produced viable offspring, suggesting that this species may undergo sperm storage. This study provides data on the thermal tolerances of D. suzukii, which can be used for models of D. suzukii population dynamics, degree-day, and distribution models.

“…1, see also Gutierrez, Ponti & Dalton, 2016), including submodel considerations for reproductive diapause and influence of fruit quality or viability. The principle environmental driver for the model is temperature and key biological mechanisms such as mortality, fecundity and development rates (for each life stage) have been parameterized wherever possible using the laboratory data of Ryan et al (2016) and other literature-based estimates (Emiljanowicz et al, 2014). The model does not currently account for overwintering so all simulations run for a single year and typically begin with an initial number of adult females introduced on the date when diapause would be terminated due to adequately warm temperatures.…”

The impacts of climate change on the abundance and distribution of the Spotted Wing Drosophila (Drosophila suzukii) in the United States and Canada

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.

Cities experience changes in abiotic factors, such as warming, increases in noise and light. These changes can lead to phenotypic changes. Several studies have revealed that altered environments change phenotypes in plants and animals in cities. However, limited studies have isolated evolutionary from nongenetic changes. Here, we analyzed the evolution of thermal tolerance and diurnal activity patterns in the urban population of the fruit pest, Drosophila suzukii . Urban and rural isofemale lines were reared under constant conditions. We compared the lower and upper thermal limits (CT min and CT max , respectively), and effects of temperature exposure on the thermal limits of urban and rural populations. Common garden experiments showed that urban populations exhibit a lower CT min than rural populations, suggesting genetic difference in CT min among populations. On the other hand, the difference in CT max between urban and rural populations was not significant. Exposure to cold temperature did not affect CT min in both urban and rural populations. In contrast, exposure to hot temperature increased CT max especially in urban population, suggesting that urban populations evolved in response to urban heat. We also investigated the daily activity patterns of urban and rural populations and the effect of lifelong artificial light at night on daily activity. We found that night‐time light (dim light) reduced the total amount of activity compared to dark night condition. In addition, dim light at night altered the daily rhythm of activity and increased the activity rate at night. The effect of night light on total activity was less in urban than that in rural populations, suggesting that populations in cities evolved to mitigate decreased activity under night light. Our results showed that environmental temperature and artificial light at night evolutionarily and plastically influence ecologically important traits, such as temperature tolerance and diurnal activity.
