“…Using insecticides or new formulations that have a different mechanism than the one which the insect species pre‐adapted to as a result of climate change can also be a strategy . Alternatively, non‐insecticide management strategies such as biocontrol or cultural control should also be considered in managing insect pests in the face of climate change …”

Changes in global temperature and humidity as a result of climate change are producing rapid evolutionary changes in many animal species, including agricultural pests and disease vectors, leading to changes in allele frequencies of genes involved in thermotolerance and desiccation resistance. As some of these genes have pleiotropic effects on insecticide resistance, climate change is likely to affect insecticide resistance in the field. In this review, we discuss how the interactions between adaptation to climate change and resistance to insecticides can affect insecticide resistance in the field using examples in phytophagous and hematophagous pest insects, focusing on the effects of increased temperature and increased aridity. We then use detailed genetic and mechanistic studies in the model insect, Drosophila melanogaster, to explain the mechanisms underlying this phenomenon. We suggest that tradeoffs or facilitation between adaptation to climate change and resistance to insecticides can alter insecticide resistance allele frequencies in the field. The dynamics of these interactions will need to be considered when managing agricultural pests and disease vectors in a changing climate. © 2019 Society of Chemical Industry

“…Sands et al ), dung burial services provided by dung beetles may be threatened by ongoing climate change. Insects are highly responsive to climate change (Andrew and Hill ; Andrew and Terblanche ; Cornelissen ; Parmesan ; Robinet and Roques ), and in particular dung beetles have been shown to alter life history events, size (Wu and Sun ), species ranges (Birkett et al ; Larsen ; Menéndez et al ) and habitat selection (Menéndez and Gutiérrez ) in response to warming. Because insects are substantially impacted by warming, it can be expected that insect‐mediated ecosystem services, including dung burial services, will be altered with ongoing climate change (Prather et al ).…”

Dung beetles provide economically valuable ecosystem services to agriculture. Dung beetles are also sensitive to climate change, which may impact on the services that they provide. Using climate-controlled chambers, we investigated the potential effects of climate change on the performance of a tunnelling dung beetle, Onthophagus taurus. Over two trials, we exposed beetles to a +0°C, +2°C or +4°C increase in diurnally fluctuating field recorded temperatures and measured survival, pat departure, reproduction (brood number and size) and dung burial by beetles. Temperature treatment did not affect pat departure behaviour. Relative to the control +0°C chambers, beetle survival was higher in the +2°C chambers, but there was no difference in survival between the +0°C and +4°C chambers. In Trial 1, brood number was reduced in both the +2°C and +4°C chambers, relative to the +0°C chambers. In Trial 2, brood number was significantly reduced relative to control chambers in the +2°C chambers only. Temperature did not affect brood size. Across temperature treatments, there was a significant, positive relationship between brood number and dung burial. However, trends in brood production with temperature were not mirrored by dung burial; the only reduction in dung burial was found in the warmest treatment of Trial 2. Our results suggest that initially, warming may not substantially reduce dung burial by O. taurus; however, ecosystem services may be impacted if lower brood production eventually reduces beetle numbers. Studies such as ours identify the vulnerabilities of ecosystem service providers to climate change and in doing so are an essential first step in the management of ecosystem services under future warming.Austral Entomology (2020) 59, 353-367 bs_bs_banner † These traits were binary variables, i.e. a beetle left a chamber via the emergence trap or remained, and a beetle survived or died.Warming effects on tunnelling dung beetles 355

“…Shifts in the distribution of pests could increase their potential colonizable area, expanding areas of affected cropland . These shifts in distribution range may represent a threat to the management and control of pests, hence knowledge about the future potential distribution of these invasive species can contribute to management actions . The arrival of pest organisms in new areas due to climate change could represent a threat to food security, particularly in zones where access to water for crop irrigation is difficult due to periods of severe drought …”
