Data from: 2-D sex images elicit mate copying in fruit flies
<p><span>Although the environment is three-dimensional (3-D), humans are able to extract subtle information from two-dimensional (2-D) images, particularly in the domain of sex. However, whether animals with simpler nervous systems are capable of such information extraction remains to be demonstrated, as this ability would suggest a functional generalisation capacity. </span><span>Here, we performed mate-copying experiments in <em>Drosophila</em> <em>melanogaster</em> using 2-D artificial stimuli. Mate copying occurs when naïve females observe the mating success of potential mates and use that social information to build their own mating preference. By replacing live demonstrations with (i) photos or (ii) simplified images of copulating pairs, we found that even crudely simplified images of sexual intercourse still elicit mate copying, suggesting that <em>Drosophila</em> is able to extract sex-related information even from a degraded image. This new method </span><span>constitutes a powerful tool to further investigate mate copying in that species and sexual preferences in general.</span></p>

Divergent east-west lineages in an Australian fruit fly, (Bactrocera jarvisi), associated with the Carpentaria Basin divide
<p><em>Bactrocera</em> <em>jarvisi</em> is an endemic Australian fruit fly species (Diptera: Tephritidae). It occurs commonly across tropical and subtropical coastal Australia, from far-northern Western Australia, across the 'Top End' of the Northern Territory, and then down the Queensland east coast. Across this range, its distribution crosses several well-documented biogeographic barriers. In order to better understand factors leading to the divergence of Australian fruit fly lineages, we carried out a population genetic study of <em>B. jarvisi</em> from across its range using genome-wide SNP analysis, utilising adult specimens gained from trapping and fruit rearing. Populations from the Northern Territory (NT) and Western Australia were genetically similar to each other but divergent from the genetically uniform east-coast (=Queensland, QLD) population. Phylogenetic analysis demonstrated that the NT population derived from the QLD population. We infer a role for the Carpentaria Basin as a biogeographic barrier restricting east-west gene flow. The QLD populations were largely panmictic and recognised east-coast biogeographic barriers play no part in north-south population structuring. While the NT and QLD populations were genetically distinct, there was evidence for the historically recent translocation of flies from each region to the other. Flies reared from different host fruits collected in the same location showed no genetic divergence. While a role for the Carpentaria Basin as a barrier to gene flow for Australian fruit flies agrees with existing work on the related <em>B. tryoni</em>, the reason(s) for population panmixia for <em>B. jarvisi</em> (and <em>B. tryoni</em>) over the entire Queensland east coast, a linear north-south distance of >2000km, remains unknown.</p>

Effect of thermal acclimation on the tolerance of the peach fruit fly (Bactrocera zonata: Tephritidae) to heat and cold stress
<p>The effect of thermal acclimation on cold and heat tolerance of the peach fruit fly (<em>Bactrocera zonata</em>) was studied. Males and females were acclimated at 20, 25 and 30°C for up to 19 days following adult emergence. The critical thermal minimum (CT<sub>min</sub>) and maximum (CT<sub>max</sub>) were subsequently recorded as well adult survival following acute exposure to chilling (0 or -3°C for 2 hours). Additionally, the survival of pupae subjected for two hours to temperatures ranging from -12°C to 5°C was determined.</p> <p>The raw data collected during this study is available in the provided data file.</p>
Improving the mating competitiveness of male Anastrepha ludens (Diptera: Tephritidae) fruit flies by adding two juvenile hormone analogues
<p>Improving the mating competitiveness and survival of sterile males are direct means to increasing the effectiveness of the Sterile Insect Technique (SIT). Some insecticide growth regulators, such as the juvenile hormone analogue (JHA) Methoprene, have been used to improve the mating competitiveness of male tephritid flies by reducing their sexual maturation period. However, a decrease in the period of sexual maturation induces a reduction in survival. Here, we compared the effects of methoprene and Pyriproxyfen (PPF), another JHA, in <em>Anastrepha</em> <em>ludens</em> males. Pyriproxyfen is an insect growth regulator that exhibits higher disruption on insects’ methamorphosis than methoprene or than natural JH. . Both compounds were administered at two doses (0.05 and 0.1%) via the male diet immediately after emergence. Our results show that both Pyriproxyfen and methoprene reduced male sexual maturation. However, PPF-treated males exhibited a shorter maturation period and obtained more matings at a given age than methoprene-treated males . No significant differences were observed between the two PPF doses tested (0.05 and 0.10 %). Male survival was equally accelerated by the two compounds. Our results demonstrate that PPF can be used as a tool to improve the mating performance of sterile males.</p>

Data from: A novel protein-based fruit fly trap in melon flies Bactrocera cucurbitae for effective pest control management
<p>Agriculture remains a major source of subsistence for local communities in India. However, agricultural yield can be strongly affected by agricultural pest outbreaks. This can result in economic losses for small-scale farmers who already experience socioeconomic challenges, such as lack of appropriate infrastructure and subsidies. Sophisticated pest management techniques (e.g., sterile insect technique) are less accessible to small farmers in developing countries and therefore, alternative cost-effective approaches for pest management are needed. Here, we report our findings of a three-year-long field trial (2018 to 2020) in India which was designed to test for the potential effectiveness of a novel, slow-release formulation protein-based trap, compared to standard Cuelure traps against melon flies <em>Bactrocera</em> <em>cucurbitae</em> (Diptera: Tephritidae). Protein-bait traps can attract flies from both sexes (as opposed to males-only, chemical traps), bearing the potential to have greater long-term impact on pest populations by decreasing future reproductive potential of trapped individuals. We found that Cuelure had overall higher trapping performance, while protein-bait traps, despite trapping at lower efficiency, were equally effective for males and females. Simulations with our field data revealed that protein-bait traps can have an 'inclusive' advantage by trapping females and thereby preventing future individuals. Overall, our study highlights the potential benefits of using this alternative trapping technique to supplement pest management in developing countries.</p>
Lipidomic data of macrophages isolated from adult fruit flies (Drosophila melanogaster) 24 hours post-infection
<p>The immune response is an energy-demanding process that must be coordinated with systemic metabolic changes redirecting nutrients from stores to the immune system. Although this interplay is fundamental for the function of the immune system, the underlying mechanisms remain elusive. </p> <p>Our data show that the pro-inflammatory polarization of <em>Drosophila</em> macrophages is coupled to the production of the insulin antagonist <em>ImpL2</em> through the activity of the transcription factor HIF1α. <em>ImpL2</em> production, reflecting nutritional demands of activated macrophages, subsequently impairs insulin signaling in the fat body, thereby triggering FOXO-driven mobilization of lipoproteins. This metabolic adaptation is fundamental for the function of the immune system and an individual's resistance to infection.</p> <p>We demonstrated that analogically to <em>Drosophila</em>, mammalian immune-activated macrophages produce <em>ImpL2</em> homolog IGFBP7 in a HIF1α-dependent manner and that enhanced IGFBP7 production by these cells induces mobilization of lipoproteins from hepatocytes.</p> <p>Hence, the production of <em>ImpL2</em>/IGFBP7 by macrophages represents an evolutionarily conserved mechanism by which macrophages alleviate insulin signaling in the central metabolic organ to secure nutrients necessary for their function upon bacterial infection.</p>
