“…In our study, there was a considerable variation in the content of pteridine between female and male S. crassipalpis at 15 • C and 25 • C. Nevertheless, we found no statistical distinction in the pteridine content between female and male S. crassipalpis at 32 • C and variable temperatures. This contrasts with previous research, which showed that male flies exhibited higher pteridine levels than female flies (L. sericata, M. domestica, and Calliphora erythrocephala) [50,88]. We suspect that the lack of gender difference in the morphology of S. crassipalpis eyes and increasing temperature may be crucial factors in our findings (Figure S3 and Figure 8).…”

Flesh flies (Diptera: Sarcophagidae) are regarded as significant in medical and veterinary entomology, and their development models can be utilized as considerable markers to ascertain the minimum postmortem interval (PMImin). In this research, we explored the growth cycle and larval body length of Sarcophaga crassipalpis Macquart 1839 (Diptera: Sarcophagidae) reared under variable temperatures ranging from 15.7 to 31.1 °C, with an average of 24.55 °C and relative humidity ranges from 31.4 to 82.8% and at six fixed temperatures of 15, 20, 25, 30, 32, and then 35 °C. Moreover, pteridine from the head was used to assess adult age grading. Our results allowed us to provide three development models: the isomorphen chart, the isomegalen chart, and the thermal summation models. The time taken for S. crassipalpis to complete its development from larviposition to adult emergence at constant temperatures of 15, 20, 25, 30, 32, and 35 °C was 1256.3 ± 124.2, 698.6 ± 15.1, 481.8 ± 35.7, 366.0 ± 13.5, and 295.8 ± 20.5 h, respectively, except 35 °C, where all pupae were unable to attain adulthood. They lasted 485.8 ± 5.4 h under variable temperatures. The minimum developmental limit (D0) temperature and the thermal summation constant (K) of S. crassipalpis were 9.31 ± 0.55 °C and 7290.0 ± 388.4 degree hours, respectively. The increase in pteridine content exhibited variations across different temperatures. There was quite a considerable distinction in the pteridine contents of male and female S. crassipalpis at 15 °C (p = 0.0075) and 25 °C (p = 0.0213). At 32 °C and variable temperatures, the pteridine content between female and male S. crassipalpis was not statistically divergent. However, temperature and gender remain the main factors influencing the pteridine content in the head of S. crassipalpis. We aim to provide detailed developmental data on S. crassipalpis that can be used as a valuable resource for future research and PMI estimation.

“…Pteridines are known to accumulate in insect eyes during aging [128]. This trend has been shown in multiples dipteran species, including D. serrata Malloch (Diptera: Drosophilidae) [131], Calliphora vicina Robineau-Desvoidy, Chrysomya bezziana Villeneuve, C. megacephala (Fabricius), Cochliomyia hominivorax (Coquerel) and Lucilia sericata (Meigen) (Diptera: Calliphoridae) [132][133][134][135][136][137], Stomoxys calcitrans (Linnaeus), M. domestica, M. autumnalis De Geer, Haematobia irritans irritans (Linnaeus) (Diptera: Muscidae) [138][139][140][141], Glossina morsitans Westwood, G. pallidipes Austen, G. palpalis palpalis (Robineau-Desvoidy), G. tachinoides Westwood (Diptera: Glossinidae) [142][143][144], Boettcherisca peregrina (Robineau-Desvoidy) (Diptera: Sarcophagidae) [145], Zeugodacus cucurbitae (Coquillett) and C. capitata (Diptera: Tephritidae) [146,147], and Simulium species (Diptera: Simuliidae) [148]. The AF of pteridines has been suggested to be a tool to assess their accumulation in the body of Anopheles mosquitoes, as supported by the results of extraction and High Performance Liquid Chromatography (HPLC) analysis procedures, by reading the emission at 455 nm under 365 nm excitation [149].…”

Light-based phenomena in insects have long attracted researchers’ attention. Surface color distribution patterns are commonly used for taxonomical purposes, while optically-active structures from Coleoptera cuticle or Lepidoptera wings have inspired technological applications, such as biosensors and energy accumulation devices. In Diptera, besides optically-based phenomena, biomolecules able to fluoresce can act as markers of bio-metabolic, structural and behavioral features. Resilin or chitinous compounds, with their respective blue or green-to-red autofluorescence (AF), are commonly related to biomechanical and structural properties, helpful to clarify the mechanisms underlying substrate adhesion of ectoparasites’ leg appendages, or the antennal abilities in tuning sound detection. Metarhodopsin, a red fluorescing photoproduct of rhodopsin, allows to investigate visual mechanisms, whereas NAD(P)H and flavins, commonly relatable to energy metabolism, favor the investigation of sperm vitality. Lipofuscins are AF biomarkers of aging, as well as pteridines, which, similarly to kynurenines, are also exploited in metabolic investigations. Beside the knowledge available in Drosophila melanogaster, a widely used model to study also human disorder and disease mechanisms, here we review optically-based studies in other dipteran species, including mosquitoes and fruit flies, discussing future perspectives for targeted studies with various practical applications, including pest and vector control.
