Yet, the neural mechanisms that govern this division and the associated behavioral differentiation among castes remain obscure. In this study, we systematically characterized the anatomical features of dopamine neurons in the brain of Monomorium pharaonis and compared the cell number and spatial distribution of these neurons across castes. We identified 17 anatomically distinct clusters of dopamine neurons in the ant brain, with cell numbers varying from ∼322 to ∼431 across castes. The major dopamine clusters are located in brain regions analogous to those in flies, with 2 clusters, PAL and PPL1 exhibiting significantly higher cell numbers in ants than in flies. Notably, 4 clusters, DAM, D1, DPL, and PPL2, showed remarkable variation in cell numbers across castes. Using single-cell transcriptomics, we identified specific molecular markers for subdividing dopamine neurons. We validated the expression of multiple neuropeptide genes in specific dopamine clusters. In particular, we found that PPL2 cluster can be further divided into 2 subclusters, PPL2a and PPL2b, which are partially labeled by the peptide gene Nplp1. PPL2b neurons, characterized by larger cell bodies, and present only in unmated queens and males, are absent in mature queens and workers. These neurons are located adjacent to Nlg2-expressing lobular neurons, which are also absent in workers and may play a role in regulating mating behaviors. Our findings provide a foundation for further investigation into the neural mechanism underlying division of labor and caste-specific behaviors in ant.","PeriodicalId":13618,"journal":{"name":"Insect Science","volume":" ","pages":""},"PeriodicalIF":2.9,"publicationDate":"2025-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144505600","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

SIT relies primarily on mass-reared insects, which are subjected to the effects of selection during colonization and rearing, and that frequently result in modifications of their biology and behavior. Here, we propose and evaluate a novel \"bi-environmental cage\" for colony management which promotes more natural sexual selection. The cage allows each sex to reach sexual maturity in separate compartments acclimatized according to natural conditions. Females mature in areas where they can recognize oviposition sites, while males mature in areas populated with small trees to allow establishment of territories in leks and performance of courtship behaviors. To determine whether the bi-environmental cage can minimize the potential adverse effects on mating competitiveness, two strains of A. ludens were tested; wild flies strain and genetic sexing strain Tapachula 7 (mass-reared flies). We found that after 4 generations in the mass-reared flies in the bi-environmental cage showed a level of fecundity similar to that of flies from the conventional cage. A similar pattern was also seen in the case of wild flies in both types of cages. In addition, other biological attributes of the wild strain assessed over six generations showed adaptability to mass-rearing conditions. Wild males from the bi-environmental cages were more sexually competitive than those from the conventional cage. Our results show that it is possible to mitigate many of the detrimental effects of domestication on the sexual performance of mass-reared males by using close-to-natural conditions for colony management.","PeriodicalId":13618,"journal":{"name":"Insect Science","volume":" ","pages":""},"PeriodicalIF":2.9,"publicationDate":"2025-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144505598","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, we know very little about the genes and processes involved in the key steps of the poisoning sequence. Besides, the excessive and indiscriminate use of insecticides is generating mechanisms of resistance in various insect pests. To improve our understanding of insecticide toxicity, we need a powerful model organism to help describe the processes underlying insecticide poisoning and the use of genomic tools to identify and analyze the genetic basis of the toxicological response of the insecticides. In this context, we associate variation in toxicological response with genomic variation, to identify genetic polymorphisms underlying the different steps of the insect (genotype)-response (phenotype)-insecticide (environment) interaction. We investigate the genetic factors involved in the toxicological response of D. melanogaster lines when exposed to spinosad and lambda-cyhalothrin through the measured of KT50 in adult males. Since the genomes of all lines evaluated are completely sequenced, we performed a Genome Wide Association Study that enabled us to identify genetic polymorphisms and candidate genes responsible for the overall phenotypic variation.

Adhesion was measured by contact angle and surface tension, and UV resistance was assessed. The transport of CLAP@MSNs within plants was observed using confocal fluorescence microscopy. Additionally, larval bioassay experiments and RNA-seq analyses were conducted on CLAP@MSNs. The results indicate that CLAP (35.6% w/w) has been successfully loaded onto MSNs.

Interestingly, CLAP@MSNs exerted no harmful effects on growth of plants and development of non-target organisms.

Investigating the molecular mechanisms regulating immune defense response in termites is beneficial for developing novel approaches to termite management. Currently, research mainly focuses on coding RNAs in termite immunity, with limited exploration of non-coding RNAs. Here, we identified miR-701, a markedly downregulated microRNA (miRNA) in the globally significant termite pest Coptotermes formosanus after Metarhizium anisopliae infection, which targets the immune gene Toll4. Transcriptome analysis of termites injected with miR-701 agomir revealed that miR-701 affects the immune-related response, growth, and development of termites. Treatment with miR-701 agomir, either through injection or ingestion, resulted in a notably reduced survival rate of termites infected with M. anisopliae compared to the control group infected with M. anisopliae alone. Additionally, termites injected with miR-701 agomir exhibited a significant decrease in the expression of antimicrobial peptide genes termicin and lysozyme, alongside a notable increase in the colony-forming units of M. anisopliae in the infected termites. Subsequent investigations demonstrated that miR-701 suppressed the expression of the target gene Toll4, consequently inhibiting the Toll signaling pathway and diminishing the expression of antimicrobial peptides. These findings suggest that termites can combat M. anisopliae by downregulating miR-701 expression to activate the Toll signaling pathway and enhance antimicrobial peptides synthesis. This discovery improves our comprehension of the role of miRNAs in termites' immune responses and the mechanism of termites managing miRNAs to boost their pathogen resistance. Additionally, it reveals a new molecular target for termite biological control.","PeriodicalId":13618,"journal":{"name":"Insect Science","volume":" ","pages":""},"PeriodicalIF":2.9,"publicationDate":"2025-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144475092","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We manipulated the resource availability for each breeding pair by providing either a large or a small mouse carcass. Furthermore, we constructed the presence of intraspecific and interspecific competition for pairs breeding on large carcasses, by introducing an additional, small pair of beetles and blowfly maggots Calliphora, respectively. We found that, compared with males and females breeding on large carcasses, males did not change their care, whereas females increased their care when breeding on small carcasses. In the presence of another pair of beetles, both males and females of the focal pair increased their care, whereas in the presence of blowfly maggots, they decreased their care. Our results showed that males and females adjust their parental care based on resource availability and competition pressure, with sex-specific differences driven by ecological and social factors.

Here, we review the variety of form and function in ant predation. Predation and scavenging were likely the plesiomorphic modes, with Cretaceous ants evolving mandibles well-suited to prey capture. In contemporary ground-dwelling species, mandible morphology can vary with adaptations to capturing particular prey as they may possess trap-jaw, snapping, or falciform mandibles characterized by their high closure speed. To capture termites or other ants, specialized ants may eliminate guards to prey on workers and brood or use allomones that cause the workers of raided nests to flee, providing access to the brood. Among arboreal ants, many species rely on vision to detect flying insects that land on their host trees. In tropical rainforests, territorially dominant arboreal ants (TDAAs) often hunt in groups, spreadeagling their prey, while venom use is noted in only a few species. Some obligate plant-ant species have developed ambush strategies for prey capture, building traps or hiding in shelters. Consequently, ants, due to their large number, their species diversity, and their capacity to live from the ground to tree crowns, regulate all kinds of arthropods through their predation. Ground-dwelling ants impact arthropods in the leaf-litter or provide biotic protection on small plants, but rarely on trees, while the TDAAs that occupy tree crowns protect their host trees from defoliating insects.","PeriodicalId":13618,"journal":{"name":"Insect Science","volume":" ","pages":""},"PeriodicalIF":2.9,"publicationDate":"2025-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144475095","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, developing effective strains through genetic manipulation of sex-determination genes remains challenging due to limited knowledge of this pathway in B. carambolae. In this study, the structures of three key orthologous genes-transformer (tra), transformer-2 (tra-2), and doublesex (dsx)-were characterized and compared with those of other Bactrocera species. These genes were found to share conserved structures, following a bottom-up pattern from Bcardsx to Bcartra-2 and Bcartra, with intron retention observed in Bcartra as a structural variation. Developmental expression analysis revealed that the splicing patterns of Bcartra first appeared at 6 hours post oviposition (hpo), with sex-specific patterns established by 10 hpo. The expression profiles in B. carambolae were similar to those in the closely related species B. dorsalis, although gene expression occurred later in B. carambolae. RNAi knockdown of Bcartra resulted in nearly all phenotypic males, supporting the role of BcarTRA in controlling the sex-specific splicing of Bcartra itself and the downstream genes doublesex and fruitless. Additionally, in silico predictions of protein interactions (TRAF, TRA-2, and RBP1) and putative cis-regulatory elements on Bcartra pre-mRNA suggested specific binding events occur at these conserved sites.

Males are polymorphic in their hindwing coloration across the Holarctic distribution range, while females exhibit continuous variation in their coloration. In the Caucasus region, a striking exception can be found, where both sexes exhibit a continuous orange-red hindwing coloration. Yet, it remains uncertain whether significant color variations exist within the spectrum of male orange-red coloration and whether these differences can be associated with genetic structure or other phenotypic traits such as size. Using population genetics and image analyses methods, we find that males from the Lesser Caucasus have predominantly large red wings and constitute mostly a single genetic population.
