“…In study 2 and in Bergh et al (2017), H. halys naturally exit the overwintering shelter over several months, suggesting that there is no single environmental cue to trigger emergence. Although temperature and photoperiod are known to affect development and reproductive status of H. halys (Niva & Takeda, 2003;Nielsen et al, 2008;Toyama et al, 2011;Cira et al, 2016), they may not be the only factors to influence emergence. Funayama (2012) suggests that adult H. halys might leave overwintering in search of food to replenish their nutrient reserves.…”

Brown marmorated stink bug, Halyomorpha halys (St al) (Hemiptera: Pentatomidae), has become a major pest for agricultural growers since it arrived in the USA and Europe. To better understand the energetic requirements of overwintering, dispersal, and reproduction of this invasive pest, we monitored the weight, egg load, lipid, glycogen, and sugar levels of adult H. halys populations in western Oregon, USA, over 2 years. In the first study, overwintering H. halys collected monthly from inside shelters exhibited a consistent decline in weight, glycogen, and sugar levels from October to June. In the second study, post-overwintering adults that exited shelters in late spring had lower lipid, glycogen, and sugar levels than those that exited in early spring. Also, adults that just exited shelters had lower weight, glycogen, sugar, and sometimes lipids than adults that remained in diapause. Sugar levels declined the most during winter, followed by lipid and glycogen. These findings suggest that nutritional depletion may cause H. halys to emerge from diapause. In the third study, overwintered and first-generation adults (G 1 ) were simultaneously collected from holly in July and August. Overwintered adults often had lower nutrient levels than G 1 adults, which may reflect overwintered adults having expended energy for dispersal and reproduction. In the fourth study, we evaluated whether the Nutrient Index [weight (mg)/prothorax width (mm) 3 ], a convenient index of physiological status, correlated with nutrient reserves. The Nutrient Index correlated with the adults' lipid, glycogen, or sugar levels in 57% of cases, ranging from weakly negative to moderately positive correlations.

“…In our studies, "frozen" equated to the onset of freezing, as evident from the detection of an exotherm; the extent of freezing was not measured. We followed the statistical procedures described in Cira et al [47]. For each host species within a winter, the difference in mortality rates between chilled and frozen individuals was tested by using Fisher's exact test (Chi square) in SAS (Proc TABULATE).…”

Abstract:The emerald ash borer, Agrilus planipennis Fairmaire, is invading North America and Europe but has not yet reached its ultimate distribution. Geographic differences in host availability and winter temperatures might affect where this species will occur. In central North America, black ash (Fraxinus nigra) is more abundant than green ash (F. pennsylvanica) at northern latitudes, but much of our current understanding of A. planipennis cold tolerance is based on observations of overwintering larvae from green ash. The effects of black and green ash on the cold hardiness of A. planipennis larvae were measured over three winters. Supercooling point, the temperature at which insect bodily fluids spontaneously begin to freeze, was marginally greater for larvae from artificially-infested black ash than green ash in one trial, but not in three others. Host species also did not consistently affect mortality rates after larval exposure to subzero temperatures, but larvae from black ash were less cold hardy than larvae from green ash when there were differences. Comparisons of mortality rates among chilled (unfrozen) and frozen larvae indicated that overwintering A. planipennis larvae are primarily freeze avoidant, and this cold tolerance strategy is unaffected by host. All of our studies suggest that A. planipennis larvae from black ash are not more cold hardy that larvae from green ash. Where temperatures annually decline below~−30 • C, overwintering morality may substantially affect the population dynamics and future impacts from this invasive alien species.

“…Given that BMSB is a chill-intolerant species and mortality due to cold stress commences at temperatures as high as 4 • C [69], the ascending altitudinal gradient in Val di Non might be hampering the capacity of BMSB to spend the winter and overcome cumulative cold temperatures in this region. This might explain the unsuitability for BMSB establishment in this critical zone for the time being.…”

Abstract:The brown marmorated stink bug, Halyomorpha halys Stål (Hemiptera: Pentatomidae), is an invasive pest that has expanded its range outside of its original confinements in Eastern Asia, spreading through the United States, Canada and most of the European and Eurasian countries. The invasiveness of this agricultural and public nuisance pest is facilitated by the availability of an array of suitable hosts, an r-selected life history and the release from natural enemies in the invaded zones. Traditional monitoring methods are usually impeded by the lack of time and resources to sufficiently cover large geographical ranges. Therefore, the citizen science initiative "BugMap" was conceived to complement and assist researchers in breaking down the behavior of this invasive pest via a user-friendly, freely available mobile application. The collected data were employed to forecast its predicted distribution and to identify the areas at risk in Trentino, Northern Italy. Moreover, they permitted the uncovering of the seasonal invasion dynamics of this insect, besides providing insight into its phenological patterns, life cycle and potential management methods. Hence, the outcomes of this work emphasize the need to further integrate citizens in scientific endeavors to resolve ecological complications and reduce the gap between the public and science.
