Chemical communication is primarily used to search for and recognize a potential mate. At close range, cuticular hydrocarbons (CHCs) are known to serve as mate recognition cue. In this study, we assessed the role of CHCs and social cues in mate and sex recognition through behavioral assays in ladybird beetle, <i>Cheilomenes sexmaculata</i>. To examine the role of CHCs in sex and mate recognition focal males were exposed to alive males and females and CHCs washed females (immersed in chloroform for 5 min, 30 min and 24 h) respectively. For social cues, males were made to encounter alive as well as dead males and females. Their copulation attempts and mating parameters (time to commence mating and copulation duration) were recorded. We also assessed whether males only mounted the dead females or copulated with them (i.e., transferred ejaculate). Our results revealed that focal males showed higher copulation attempts with alive individuals, regardless of sex. However, they attempted copulation with dead females significantly more often than with dead males. Washing of CHCs significantly influenced copulation attempts, with unwashed beetles showing a 100% attempt rate, followed by those immersed in chloroform for varying durations. Males initiated mating sooner and engaged in longer copulation with alive females compared to dead ones. Although, males mounted and copulated with dead females, no difference in sperm transfer was observed compared to alive females. Our study demonstrated that CHCs along with social cues (such as movement), play a pivotal role in eliciting male copulatory behavior.</p></div>","PeriodicalId":6879,"journal":{"name":"acta ethologica","volume":"28 3","pages":"171 - 179"},"PeriodicalIF":1.3,"publicationDate":"2025-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145110480","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These beetles often coexist and interact, and such interactions may result in reduced female fitness. To assess the impact of conspecific and heterospecific males (<i>P. dissecta</i>) on the reproductive output of <i>C. sexmaculata</i> females, we conducted three experimental treatments: control, conspecific, and heterospecific. Our results indicated that during mating, conspecific males exerted significant interference due to species similarity, disrupting mating attempts of <i>C. sexmaculata</i> females. Following copulation with conspecific males, a reduction in fecundity and egg viability was observed regardless of whether the females were subsequently housed with conspecific or heterospecific males. Multiple mating events occurred in the conspecific treatment, while no heterospecific mating was recorded in the heterospecific treatment. These findings suggest that both conspecific and heterospecific interactions negatively affect the reproductive success of <i>C. sexmaculata</i>, potentially limiting the efficacy of these beetles as biocontrol agents. Further investigation into the mechanisms driving these interspecies interactions is essential to optimise the use of these beetles in integrated pest management strategies.</p>\u0000 </div>","PeriodicalId":6879,"journal":{"name":"acta ethologica","volume":"28 3","pages":"151 - 160"},"PeriodicalIF":1.3,"publicationDate":"2025-07-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145170257","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aimed to assess how burned areas affect on the foraging behavior of <i>Pseudomyrmex termitarius</i> (Smith, 1855) in the Cerrado. We conducted the research in the northeast of Brazil, specifically in Vargem Grande, Maranhão, Brazil. We studied eight ant nests from two areas: a control area and a burned area.

The distances traveled by ants from their nests were analyzed using the Friedman non-parametric test. Additionally, to compare the home ranges, each polygon was fragmented, and the sides of the geometric shapes were analyzed using the same test. The results showed that although the size of the home ranges for <i>P. termitarius</i> remained unchanged, the extent of their foraging routes was significantly larger in the burned area.</p></div>","PeriodicalId":6879,"journal":{"name":"acta ethologica","volume":"28 3","pages":"161 - 169"},"PeriodicalIF":1.3,"publicationDate":"2025-07-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145110552","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

When signals from different channels are emitted together or alternated, they create a multimodal form of communication that serves to enhance, complement, or convey crucial information. This holds particular significance for species inhabiting noisy environments, such as members of the Hylodidae family, which comprises species that dwell in rivers and streams (rheophilic frogs) and exhibit a diverse behavioral repertoire, including acoustic, visual, and tactile signals. In this natural history study, we observed a <i>Hylodes heyeri</i> population, documenting their reproductive and agonistic interactions among individuals. The <i>H. heyeri</i> social interactions are mediated by acoustic, visual, and tactile stimuli, in a multimodal context. We reported the use of four different visual signals – arm and leg lifting, leg stretching, and toe flagging. Most males exhibited aggressive behavior when intruder males entered their calling area and demonstrated site fidelity for consecutive days. Although diverse, their behavioral repertoire is still less extensive than that of congeneric species, and it is likely that a more comprehensive study would reveal a richer communication system. In spite of that, these observations contribute to filling a gap in our understanding of the multimodal communication of <i>Hylodes</i> species.</p></div>","PeriodicalId":6879,"journal":{"name":"acta ethologica","volume":"28 3","pages":"181 - 188"},"PeriodicalIF":1.3,"publicationDate":"2025-07-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145110564","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, ornamental male <i>Betta splendens</i>, a model organism for aggression research, were analysed for intra- and inter-individual variability in aggressive responses to their mirror image—a standard method for assessing aggression in fish—once per week, and their consistency was evaluated over three consecutive weeks There were significant differences in aggressive behaviour across individuals, with coefficients of variation ranging from 29 to 60%. While most fish exhibited the full suite of aggressive displays, some showed no aggressive behaviour, while others only displayed threat behaviours but did not advance to the attacks. The consistency of individual threat and attack behaviours varied, but repeatability was high overall (intra-class correlation coefficients ≥ 0.5), indicating that individual fish have different levels of aggression. There was habituation to the mirror assay, with aggression decreasing significantly by the second week, though the degree of habituation, a form of learning, varied among individuals in some behaviours. Air-breathing frequency correlated positively with aggression behaviours and can be considered an indicator to infer aggression level in this species. These results indicate that inter-individual variation in aggressive behaviour and habituation to repeated testing using the mirror assay should be considered in aggression studies using <i>B. splendens</i> and potentially in other species.</p></div>","PeriodicalId":6879,"journal":{"name":"acta ethologica","volume":"28 3","pages":"139 - 150"},"PeriodicalIF":1.3,"publicationDate":"2025-07-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s10211-025-00469-9.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145110563","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
