Impacts of climate change and host plant availability on the global distribution of Brontispa longissima (Coleoptera: Chrysomelidae)

Abstract

BACKGROUND The coconut hispine beetle Brontispa longissima Gestro (Coleoptera: Chrysomelidae) is one of the most serious pests of the coconut palm, Cocos nucifera L. (Arecales: Arecaceae) and other palms. The invasion of B. longissima causes major economic and ecological losses worldwide. In this study, the impacts of climate change on the risk of spread were evaluated. CLIMEX was used to project its global potential distribution based on historical climate data (1987–2016) and simulated future climate data (2071–2100). RESULTS The distribution of B. longissima included each continent under historical and future climate conditions. However, climate suitability was predicted to decrease in most tropical and subtropical regions under a climate change scenario. Temperature was a more important determinant of the climatic suitability of the pest than relative humidity or precipitation. The availability of host plants (Arecaceae) only had a slight impact on climate suitability in some regions. CONCLUSION The projected potential distribution of B. longissima will help to determine the impacts of climate change and will provide supportive information for the development of management strategies to reduce future economic and ecological losses. © 2019 Society of Chemical Industry

Temperature‐dependent development models describing the effects of temperature on the development of Spodoptera eridania

“…Numerous studies have demonstrated the influence that temperature exerts on the development and survival of insects 7,14,39 . Yet, because the response of insects to temperature is species‐specific, studies about the effect of temperature on insect biology are still relevant, particularly for agricultural and forest pests due to their application in pest management and prediction of species distributions under current and projected climate conditions using mechanistic or hybrid models 8,40–42 . In this context, knowledge of the thermal thresholds of insect pests may help in understanding the risks of a given species spreading to regions outside its native range.…”

The Cassidinae beetles of Longnan County (Jiangxi, China): overview and community composition

“…(Chen et al 1986, Liao et al 2014); Cassidispa relicta Medvedev is a severe threat to the dominant trees, Betula platyphylla Sukatchiev and Ulmus pumila L., in Inner Mongolian forests in recent years (Liao et al 2018b). Invasive Cassidinae species such as palm-feeding Brontispa longissima (Gestro) and Octodonta nipae (Maulik) are substantial threats to economic crops and native plants (Peng et al 2018, Zou et al 2019).…”

Prediction of the Long-Term Potential Distribution of Cryptorhynchus lapathi (L.) under Climate Change

“…The historical climate data (1987-2106) were obtained from gridded Climatic Research Unit (CRU) Time-series (TS) version 4.01 over the period 1901-2016, provided on high-resolution (0.5 • latitude, 0.5 • longitude) grids and produced by CRU at the University of East Anglia [21]. Future climate data for 2021-2040, 2041-2060, 2061-2080, and 2081-2100 were obtained based on the methods in Zou et al [22]. For detailed information on future climate data, please refer to Zou et al [22].…”
