Abstract The prevalence and intensity of parasitism can have different fitness costs between sexes, across species developmental stages. This variation could arise because specific sexual differences in body condition, immunity, resistance. Theory predicts that the will be greater individuals with poor condition larger size. These predictions been tested verified vertebrates. In insects, however, contradictory evidence has found taxa. Here, we these on two Agriocnemis ( femina pygmaea ) damselflies, which are parasitized by Arrenurus water mite ectoparasites. We measured weight, total length, abdomen area thorax non-parasitized damselflies varied males females, immature females mature A. . Then, calculated parasite prevalence, i.e., frequency intensity, number parasites per infected damselfly eleven natural populations both species. line to our predictions, observed than but no difference females. Furthermore, load was higher Our result also showed studied species, being study provides impacts stages differentially suggests may occur due sex, stage, species-specific resistance tolerance mechanism.

Abstract The colours of insects function in intraspecific communication such as sexual signalling, interspecific protection from predators, and physiological processes, thermoregulation. expression melanin‐based is temperature‐dependent thus likely to be impacted by a changing climate. However, it unclear how climate change drives changes body wing colour may impact insect physiology their interactions with conspecifics (e.g. mates) or heterospecific predators prey). aim this review synthesise the current knowledge consequences climate‐driven on insects. Here, we discuss environmental factors that affect colours, then outline adaptive mechanisms terms phenotypic plasticity microevolutionary response.

Abstract Studies of female mate choice commonly use virgin females as test subjects, either to control for the effects mating or because are presumed be more responsive cues. Theory predicts that will less choosy they risk dying without mating. Moreover, in many species, spend their lives mated than virgins. Thus, exclusive studies may underestimate strength direction and fail reflect natural decisions. We conducted a systematic meta-analysis focusing on three scenarios which might differ females: reproductive isolation, inbreeding avoidance, sexually transmitted disease. Using only was common (53% 303 studies). In addition, 38% lacked information history. Contrary predictions, we found no evidence were females. Nevertheless, excluding from leaves an important gap our understanding role preferences evolution. therefore encourage future consider context include subjects when relevant.

Here, we aim establish vulnerability an ectothermic insect a warming estimating safety margin in Ischnura heterosticta damselflies. We measured critical maximum (CTmax) along latitudinal gradient 17° from 21 populations eastern coast Australia. Our results showed that damselflies inhabiting tropical had higher CTmax than temperate increased with increasing mean decreasing latitude. further found positive correlation damselfly parasite number temperature.

In the past 50 years, odonatology has advanced on a global scale in phylogenetics, diversity, organismal and population ecology, conservation biology. This study explored if such knowledge gains are perceived to have occurred India, as they did worldwide, identified gaps challenges that might be hindering progress Indian odonatology. Responses an online questionnaire semi-structured interviews with researchers country indicated majority of Odonata research had regionally Western Ghats areas taxonomy species distribution. Knowledge included northeast known for its rich biodiversity, studies ensure evidence-based ecosystem management. Respondents also lack larvae despite this being longest stage taxa’s life cycle. Key faced by odonatologists were reported funding laboratory field resources poor access papers published journals. Social media platforms could aid addressing some through engaging citizen scientists facilitating skill-building knowledge-sharing among country.

Abstract Sexual selection can improve population fitness and purge deleterious mutation from the gene pool by promoting condition‐dependent mate selection. One ecological factor that reduces individual condition is parasitism. Parasitism tends to increase hosts' load likely indicates inferior host genetic quality. Parasite‐mediated selection, therefore, should favour mating success of parasite‐resistant individuals over parasitised individuals. We tested this hypothesis in male Agriocnemis pygmaea damselflies, which are Arrenurus water mites. calculated frequency (i.e. proportion parasitism) intensity number parasites per individual) parasitism free‐flying males copula seven natural populations. predicted observed will be less than expected based on population. further parasite would lower caught single males. found were significantly non‐parasitised males, independent their occurrence frequency. However, there was no difference average between captured or Our study shows addition sexual a strong agent against implies it could promote local adaptation counteract driven extinction risks.

Insects exhibit diverse colours that play a crucial role in communication directs inter- and intra-species interactions such as predator-prey sexual selection. Anthropogenic climate change may impact insects colour expression consequently their physiology behaviour. can respond to changing climatic through phenotypic plasticity or genetic modification, however it is unclear how any of the resulting changes body wing with conspecifics heterospecific (e.g., predator, prey, mate). The aim this review synthesis current knowledge consequences driven on insects. Firstly, we discussed environmental factors affect insect colours, then outlined adaptive mechanisms terms microevolutionary response. Secondly, conducted systematic performed qualitative analysis understand experimental rearing temperature influences colouration. Finally, gave an overview beneficial maladaptive We concluded by identifying research gaps highlight potential future areas.
