“…Common species, such as the Chinese mantis ( Tenodera sinensis) , have been used to study and model predator behavior [35–40]. Recent work has begun to characterize the metabolic rates of praying mantises [41]. However, to our knowledge, there has been no in-depth study of praying mantis nutritional requirements.…”

Praying mantids are predators that consume a wide variety of insects. While the gut microbiome of carnivorous mammals is distinct from that of omnivores and herbivores, the role of the gut microbiome among predatory insects is relatively understudied. Praying mantids are the closest known relatives to termites and cockroaches, which are known for their diverse gut microbiota. However, little is known about the mantid gut microbiota or their importance to host health. In this work, we report the results of a 16S rRNA gene-based study of gut microbiome composition in adults and late-instar larvae of three mantid species. We found that the praying mantis gut microbiome exhibits substantial variation in bacterial diversity and community composition. The hindgut of praying mantids were often dominated by microbes that are present in low abundance or not found in the guts of their insect prey. Future studies will explore the role of these microbes in the digestion of the dietary substrates and/or the degradation of toxins produced by their insect prey.

“…After imbibing a bloodmeal, which could be >100-fold their body mass, ticks digest and store incoming nutrients primarily in cells of the midgut (Sonenshine, 1991). These energy stores are likely preserved by the remarkably low metabolic rate of ticks, which is approximately 1/10th that of similar sized insects (Lighton & Fielden, 1995;McCue, Salinas, Ramirez, & Wilder, 2016;Terblanche, Klok, Marais, & Chown, 2004), thereby contributing to their survival during starvation. When the nonfed state persists, ticks utilize their nutrients through a variety of pathways, and autophagy seems to be particularly important during starvation (Umemiya-Shirafuji et al, 2010).…”

Ticks are obligatorily hematophagous but spend the majority of their lives off host in an unfed state where they must resist starvation between bouts of blood feeding. Survival during these extended off‐host periods is critical to the success of these arthropods as vectors of disease; however, little is known about the underlying physiological and molecular mechanisms of starvation tolerance in ticks. We examined the bioenergetic, transcriptomic and behavioural changes of female American dog ticks, Dermacentor variabilis, throughout starvation (up to nine months post‐bloodmeal). As starvation progressed, ticks utilized glycogen and lipid, and later protein as energy reserves with proteolysis and autophagy facilitating the mobilization of endogenous nutrients. The metabolic rate of the ticks was expectedly low, but showed a slight increase as starvation progressed possibly reflecting the upregulation of several energetically costly processes such as transcription/translation and/or increases in host‐seeking behaviours. Starved ticks had higher activity levels, increased questing behaviour and augmented expression of genes related to chemosensing, immunity and salivary gland proteins. The shifts in gene expression and associated behavioural and physiological processes are critical to allowing these parasites to exploit their ecological niche as extreme sit‐and‐wait parasites. The overall responses of ticks to starvation were similar to other blood‐feeding arthropods, but we identified unique responses that could have epidemiological and ecological significance for ticks as ectoparasites that must be tolerant of sporadic feeding.

“…Other factors that are known to influence metabolism include activity and feeding status, yet few studies disentangle these effects fully across multiple environmental conditions (Halsey et al, 2015). While feeding effects are widely reported in metabolic studies of insects, typically the time-courses of these responses are not well characterised, and in only a few cases is this undertaken at different temperatures (Hill et al, 2020;McCue et al, 2016aMcCue et al, , 2016b. In this study, the average SDA of larvae measured at 20°C was significantly lower compared to larvae measured at 30°C.…”

“…Therefore, we could not fully capture the precise start point, and hence, the entire time-course, of the postprandial metabolic response in this study. This is a challenge of determining SDA noted in other studies too (McCue et al, 2016b). Another constraint in calculating the cost of digestion (SDA) in C. newmannii was due to larvae remaining active during the digestion period.…”
