However, their ‘world of sound’ remains largely unexplored. Here, we review 153 years of bark beetle bioacoustics publications to summarize current knowledge, identify gaps and suggest future research directions. Our survey identified 117 publications covering 170 species. Morphological reports revealed five stridulatory organs across 125 species, with elytro-tergal, gular-prosternal and vertex-pronotum mechanisms being the most prevalent for sound production. However, confirmed sound recordings exist for only 40 species. Acoustic signalling in adults is proposed to function in avoiding enemies, pair formation, sexual selection and spacing, while in juveniles, vibratory communication is proposed for gallery spacing. However, experimental evidence supporting these functions is lacking. Acoustic sensory organs remain unidentified, and comprehension of signal transmission—whether through airborne sounds or solid-borne vibrations (or both)—is limited. Bioacoustic technologies have emerged as tools for potential management practices and are also discussed. Based on these findings, we recommend three directions for future research: (1) characterize acoustic morphology and behaviours in more species, particularly unrepresented taxa, with recordings in various contexts, preferably under natural conditions; (2) test hypotheses to explain the functions of acoustic communication through experimental and comparative phylogenetic methods and (3) investigate how sounds or vibrations are transmitted and received through behavioural and neurophysiological experiments.

Adult flies feed on fermented fruit, but their larvae are obligate parasites that feed on, and often cause the mortality of, the developing nestlings. Various techniques for the control of this parasite are currently under study, but the inability to rear flies in captivity has slowed progress. To help understand the reproductive behaviour of <i>P. downsi</i>, in this study, we measured the reproductive organs of male and female flies to determine the age flies mature physiologically, as well as the influence of the larval and adult diets on this process. Both females and males reared from larvae that had developed in the wild on live birds reached physiological maturity at 6 days; in the males, this was associated with increased pigmentation of the testes and the presence of free sperm, and in the females, mature eggs. Females reared in the laboratory on an artificial diet produced mature eggs at 6 days. However, the ovaries of laboratory-reared females were statistically smaller than those of wild females, suggesting that egg production was affected by larval diet. Physiological maturity was delayed in laboratory-reared males, taking twice as long. The testes of these males had more unpigmented areas and deformities indicating that the artificial larval diet was insufficient. Enrichment of the adult diet could help compensate for this. The addition of methoprene (M) to the diet was found to have a positive effect on the sexual development of the flies. In females, a diet of sugar + yeast hydrolysate (YH) in a 3:1 ratio combined with M favoured the development of larger ovaries and the production of mature eggs at an earlier age (3 days). In the case of males, a diet with YH increased testis size and M accelerated the growth of testis length even when males were fed only with sugar and without YH.

Next, we examine fasting-induced starvation resistance across isofemale lines collected across latitudes and in different seasons, and among inbred lines derived from flies collected on different continents.

Specifically, we measured lipid, protein and water-soluble carbohydrate concentrations. We tested the hypothesis that when insects feed from plants with altered nutritional content, they incur a cost in dealing with such biotic stresses. That cost reduces their metabolic well-being and, thus, reduces their nutritional status with respect to parasitoids developing at their expense.
