Temperature-driven differences in phenology and habitat suitability for brown marmorated stink bug, Halyomorpha halys, in two ecoregions of North Carolina

In the last decade, the invasive brown marmorated stink bug Halyomorpha halys, native to East Asia, has become one of the most serious pests for agricultural crops worldwide. First detected in Europe (in Switzerland), the insect is now widely found across the European continent and many Eurasian countries. Since its first appearance in Slovenia in 2017 it has caused considerable damage to fruit and vegetable production. Understanding the biology and behavior in the local environmental conditions is of key importance for an effective pest management. Knowledge of the voltinism of the species is crucial to anticipate critical phases of pest development and for adapting control measures that target the vulnerable life stages of the pest. A 3-year study (2019–2021) of H. halys biological parameters was performed outdoors in Nova Gorica (western Slovenia), confirming that in the sub-Mediterranean climate this pest has two overlapping generations per year. The net reproductive rates observed in the studied period indicate growing populations. The highest population growth was recorded in 2019, when the net reproductive rate of increase (R0) reached 14.84 for the summer generation and 5.64 for the overwintering generation. These findings match the current situation in Slovenia, where increasing populations of H. halys and severe crop damage have been observed since 2019.

“…As noted above, populations of the brown marmorated stink bug are bivoltine or partially bivoltine throughout most of the species’ native [ 12 , 17 , 18 , 30 ] and invasive [ 11 , 23 , 28 , 29 , 33 , 34 , 35 , 36 , 37 ] geographic ranges, although in some colder regions only one generation per year is produced [ 19 , 25 , 30 , 56 , 57 ]. The results of the regular field sampling during the four consecutive years and the monitoring of several morphological, physiological, and demographic parameters clearly indicate that in the Sochi region, H. halys is at least partially bivoltine: the main period of mass oviposition (by the overwintered females) occurs in June–July; the second much shorter period of egg-laying (by females of the new, i.e., the first, generation) followed by a new peak in the abundance of early instar nymphs occurs in August ( Figure 2 ).…”

“…Recently H. halys was recorded on the northern coast of the Black Sea: in Abkhazia and the Krasnodar Territory of Russia [ 13 , 14 , 15 , 16 ]. The phenology and seasonal cycle of H. halys have been studied in various regions [ 4 , 17 , 18 , 19 , 20 , 21 , 22 , 23 , 24 , 25 , 26 , 27 , 28 , 29 ]. It is known that although the brown marmorated stink bug is potentially multivoltine, within its native range in China, Korea, and Japan, it produces only one or two generations per year.…”

“…In such cases, overwintered females from bivoltine populations start to lay eggs in May, whereas adults of the first generation oviposit from June to July [ 30 ]. In North America, the invasive populations of this species are also bivoltine or at least partially bivoltine [ 19 , 29 , 31 , 32 , 33 , 34 , 35 , 36 ]. In Italy, H. halys produces two generations per year as well, and overwintered bugs lay eggs from May to August, and females of the first generation do so from July to September [ 37 ], whereas the Swiss population is univoltine, the oviposition period lasts from June to September [ 19 ].…”

To Every Thing There Is a Season: Phenology and Photoperiodic Control of Seasonal Development in the Invasive Caucasian Population of the Brown Marmorated Stink Bug, Halyomorpha halys (Hemiptera: Heteroptera: Pentatomidae)

Studies on the phenology of local populations of invasive insects are necessary for monitoring and predicting their dispersion. We investigated the phenology of the brown marmorated stink bug, Halyomorpha halys, in the Sochi region (Krasnodar Territory, Russia) from 2018 to 2021 by regular field sampling and dissecting. The results of the sampling suggest that H. halys is at least partially bivoltine in the studied region: the main period of mass oviposition (by the overwintered females) occurs from June to July; the second, much shorter period of egg-laying (by females of the new, i.e., the first generation) occurs in August. Reproductively active individuals (i.e., females with developed ovaries and filled spermatheca and males with filled ectodermal sac) were recorded from the end of May to the beginning of September. Such a seasonal pattern correlated with day length: when the natural photoperiod decreased below the experimentally determined critical day length (15.0–15.5 h), the proportions of females with fully developed ovaries sharply dropped to zero. Both the rate of H. halys pre-adult development and the timing of the induction of winter adult diapause observed under natural conditions fully agreed with the earlier predictions that had been based on the results of laboratory experiments.

“…The impact of temperature on development, fecundity, survival, and mortality of an invasive pest such as H. halys can be used to determine its invasive potential [ 4 ] and seasonal risk [ 9 , 10 ]. Previous reports provided similar detailed egg and nymphal developmental periods, survival rates, and degree-day (DD) temperature requirements for H. halys [ 4 , 10 , 11 , 12 , 13 , 14 ]. Eggs and nymphs are unable to complete development to the adult stage at temperatures below 15 °C or above 36 °C [ 4 ].…”

Brown marmorated stink bug, Halyomorpha halys (Stål) (Hemiptera: Pentatomidae), is a generalist pest that causes serious injury to a variety of crops around the world. After the first detection in the USA, H. halys became a serious threat to growers resulting in significant crop damage. Understanding the effect of temperature on H. halys development will help to achieve successful control by predicting the phenological timing of the pest. Here, life table parameters (survival, development, reproduction, and daily mortality) of H. halys were evaluated for New Jersey and Oregon populations in the US. Parameters were determined from field-collected and laboratory-reared individuals. The results indicated that New Jersey populations had higher levels of egg-laying than Oregon populations and exhibited higher and earlier fecundity peaks. Survival levels were similar between populations. Linear and nonlinear fit were used to estimate the minimum (14.3 °C), optimal (27.8 °C), and maximum (35.9 °C) temperatures where development of H. halys can take place. An age-specific fecundity peak (Mx = 36.63) was recorded at 936 degree days for New Jersey populations, while maximum fecundity (Mx = 11.85) occurred at 1145 degree days in Oregon. No oviposition was recorded at the lowest (15 °C) or highest (35 °C) trialed temperatures. Developmental periods increased at temperatures above 30 °C, indicating that such higher temperatures are suboptimal for H. halys development. Altogether the most optimal temperatures for population increase (rm) ranged from 25 to 30 °C. Survival rates of H. halys at suboptimal low temperatures of 8 °C (i.e., 61%) is comparable to previous reports. The present paper provides additional data and context from a range of experimental conditions and populations. Such temperature-related H. halys life table parameters can be used to provide determine the risk to susceptible crops.
