Fruit Flies: Challenges and Opportunities to Stem the Tide of Global Invasions

Annual Review of Entomology, Journal Year: 2023, Volume and Issue: 69(1), P. 355 - 373

Published: Sept. 27, 2023

Global trade in fresh fruit and vegetables, intensification of human mobility, climate change facilitate fly (Diptera: Tephritidae) invasions. Life-history traits, environmental stress response, dispersal stress, novel genetic admixtures contribute to their establishment spread. Tephritids are among the most frequently intercepted taxa at ports entry. In some countries, supported by rules-based framework, a remarkable amount biosecurity effort is being arrayed against range expansion tephritids. Despite this effort, flies continue arrive new jurisdictions, sometimes triggering expensive eradication responses. Surprisingly, scant attention has been paid recent discourse about multilateral agreements. Much available literature on managing tephritid invasions focused limited number charismatic (historically high-profile) species, generality many patterns remains speculative.

Phenotypic adaptation to temperature in the mosquito vector, Aedes aegypti

Global Change Biology, Journal Year: 2023, Volume and Issue: 30(1)

Published: Nov. 27, 2023

Abstract Most models exploring the effects of climate change on mosquito‐borne disease ignore thermal adaptation. However, if local adaptation leads to changes in mosquito responses, “one size fits all” could fail capture current variation between populations and future adaptive responses temperature. Here, we assess phenotypic temperature Aedes aegypti , primary vector dengue, Zika, chikungunya viruses. First, explore whether there is any difference existing response mosquitoes populations, used a knockdown assay examine five Ae. collected from climatically diverse locations Mexico, together with long‐standing laboratory strain. We identified significant tolerance populations. Next, such can be generated by differences temperature, conducted an experimental passage study establishing six replicate lines single field‐derived population maintaining half at 27°C other 31°C. After 10 generations, found performance, maintained under elevated temperatures showing greater tolerance. Moreover, these translated shifts performance curves for multiple life‐history traits, leading overall fitness. Together, novel findings provide compelling evidence that do differ response, suggesting simplified might insufficient predicting vector‐borne transmission.

Variation in temperature of peak trait performance constrains adaptation of arthropod populations to climatic warming

Nature Ecology & Evolution, Journal Year: 2024, Volume and Issue: 8(3), P. 500 - 510

Published: Jan. 25, 2024

Abstract The capacity of arthropod populations to adapt long-term climatic warming is currently uncertain. Here we combine theory and extensive data show that the rate their thermal adaptation will be constrained in two fundamental ways. First, an population predicted limited by changes temperatures at which performance four key life-history traits can peak, a specific order declining importance: juvenile development, adult fecundity, mortality mortality. Second, directional due differences temperature peak these traits, with expected persist because energetic allocation trade-offs. We compile new global dataset 61 diverse species provides strong empirical evidence support predictions, demonstrating contemporary have indeed evolved under constraints. Our results provide basis for using relatively feasible trait measurements predict adaptive geographic gradients, as well ongoing future warming.

Bringing traits back into the equation: A roadmap to understand species redistribution

Global Change Biology, Journal Year: 2024, Volume and Issue: 30(4)

Published: April 1, 2024

Abstract Ecological and evolutionary theories have proposed that species traits should be important in mediating responses to contemporary climate change; yet, empirical evidence has so far provided mixed for the role of behavioral, life history, or ecological characteristics facilitating hindering range shifts. As such, utility trait‐based approaches predict redistribution under change been called into question. We develop perspective, supported by evidence, trait variation, if used carefully can high potential utility, but past analyses many cases failed identify an explanatory value not fully embracing complexity First, we discuss relevant theory linking shift processes at leading (expansion) trailing (contraction) edges distributions highlight need clarify mechanistic basis approaches. Second, provide a brief overview shift–trait studies new opportunities integration consider range‐specific intraspecific variability. Third, explore circumstances which environmental biotic context dependencies are likely affect our ability contribution processes. Finally, propose revealing shaping may require accounting methodological variation arising from estimation process as well addressing existing functional, geographical, phylogenetic biases. series considerations more effectively integrating extrinsic factors research. Together, these analytical promise stronger predictive understanding help society mitigate adapt effects on biodiversity.

ABSTRACT Bees are essential pollinators and understanding their ability to cope with extreme temperature changes is crucial for predicting resilience climate change, but studies limited. We measured the response of critical thermal maximum (CTMax) short-term acclimation in foragers six bee species from Greek island Lesvos, which differ body size, nesting habit, level sociality. calculated ratio as a metric assess capacity tested whether bees’ was influenced by size and/or CTMax. also assessed CTMax increases following acute heat exposure simulating wave. Average estimate varied among increased did not significantly shift treatment except sweat Lasioglossum malachurum. Acclimation averaged 9% it associated or Similarly, average increase exposure. These results indicate that bees might have limited enhance tolerance via prior exposure, rendering them physiologically sensitive rapid during weather events. findings reinforce idea insects, like other ectotherms, generally express weak plasticity CTMax, underscoring role behavioral thermoregulation avoidance temperatures.

Heat stress effects on offspring compound across parental care

Proceedings of the Royal Society B Biological Sciences, Journal Year: 2025, Volume and Issue: 292(2042)

Published: March 1, 2025

Heatwaves associated with climate change threaten biodiversity by disrupting behaviours like parental care. While care may buffer populations from adverse environments, studies show mixed results, possibly due to heat stress affecting different components. We investigated how impacts and offspring performance in the burying beetle Nicrophorus nepalensis under control (17.8°C) (21.8°C) conditions. focused on two critical periods: pre-hatching (carcass preparation) post-hatching (offspring provisioning). To disentangle vulnerability of these components stress, we reciprocally transferred carcasses prepared or females breeding both only one period did not alter reproduction, but when pre- periods experienced heatwaves, reproductive success declined. Females exhibited higher energy expenditure during provisioning, evidenced greater body mass loss. Notably, had long-lasting effects via carcass preparation, resulting smaller adult size mortality. These results highlight complexity environmental stressors care, suggesting that respond differently thus need be examined separately better understand responds to, buffers against, temperature stress.

Heatwaves are detrimental to fertility in the viviparous tsetse fly

Proceedings of the Royal Society B Biological Sciences, Journal Year: 2024, Volume and Issue: 291(2018)

Published: March 13, 2024

Heatwaves are increasing in frequency and intensity due to climate change, pushing animals beyond physiological limits. While most studies focus on survival limits, sublethal effects fertility tend occur below lethal thresholds, consequently can be as important for population viability. Typically, male is more heat-sensitive than female fertility, yet direct comparisons limited. Here, we measured the effect of experimental heatwaves tsetse flies, Glossina pallidipes , disease vectors unusual live-bearing insects sub-Saharan Africa. We exposed males or females a 3-day heatwave peaking at 36, 38 40°C 2 h, 25°C control, monitoring mortality reproduction over six weeks. For 40°C, was 100%, while 38°C peak resulted only 8% acute mortality. Females experienced one-week delay producing offspring, whereas no such occurred males. Over weeks, equivalent loss both sexes. Combined with mortality, this lead 10% decline weeks compared control. Furthermore, parental exposure gave rise female-biased offspring sex ratio. Ultimately, thermal limits should considered when assessing change vulnerability.
