Diurnal temperature fluctuations improve predictions of developmental rates in the spruce bark beetle Ips typographus

Journal of Pest Science, Год журнала: 2024, Номер 97(4), С. 1839 - 1852

Опубликована: Март 22, 2024

Abstract The European spruce bark beetle Ips typographus is a widespread pest in Norway spruce-dominated forests Eurasia. Predicting its phenology and voltinism crucial to plan forest management measures mitigate mass outbreaks. Current models are based on constant temperatures inferred from laboratory experiments; however, insect life cycles under natural conditions rather driven by diurnal seasonal temperature fluctuations. Therefore, fluctuating would reflect field more realistically might thus improve model predictions. In experiment, we investigated the development of I. , applying mean between 3 35 °C oscillations up ± 15 °C. Subsequently, calibrated developmental rate applied them climate data, order assess effect fluctuations conditions. Our results showed that significantly affected rates. Compared temperatures, was faster at falling below lower threshold, slower exceeding optimum. Furthermore, short exposures suboptimal less than expected Natural accelerate cool, shaded conditions, whilst slowing it hot, sun-exposed thereby ultimately affecting voltinism. findings highlight importance account for accurate predictions rates thermal environments, provide fundament improving current support effective warming climate.

Insects, Год журнала: 2025, Номер 16(3), С. 249 - 249

Опубликована: Фев. 28, 2025

The pine caterpillar (Dendrolimus spectabilis Bulter, Lepidoptera: Lasiocampidae) is a destructive insect threatening forest communities across Eurasia. pest polyvoltine, and under global warming, more favorable temperatures can lead to additional generations. Here, we simulated the voltinism current future climatic scenarios based on thermal physiology cumulative growing degree day (CGDD) model. Subsequently, revealed change patterns of along elevational latitudinal gradients. results showed that both CGDD are increasing. ranges from 1.26 1.56 generations (1.40 ± 0.07), with an increasing trend 0.04/10a. Similar trends expected continue climate scenarios, values 0.01/10a, 0.05/10a, 0.07/10a, 0.09/10a for SSP1-2.6, SSP2-4.5, SSP3-7.0, SSP5-8.5 respectively. At elevation gradients, increases all ranges, peaking at 500–1000 m latitudes 34–34.5° N. This study highlights increase in not limited low-elevation -latitude regions but predicted various elevations latitudes. These findings enhance our understanding how affects contribute management strategies, although this assumes linear relationship between temperature voltinism, without considering other ecological factors.
