Abstract Lateralisation is a well-established phenomenon observed in an increasing number of insect species. This study aims to obtain basic details on lateralisation courtship and mating behaviour Ostrinia furnacalis , the Asian corn borer. We conducted laboratory investigations observe behaviours adult O. . Our goal was also detect lateralised variations during sexual interactions elucidate how these variances might influence success males. findings reveal two distinct traits: male approaches from right or left side female direction turning displays. Specifically, males approaching females their predominantly exhibited left-biased 180° displays, while left-side primarily displayed right-biased Notably, males, executing turn for end-to-end genital contact, initiated copulation with fewer attempts began earlier than Furthermore, higher when subsequently approached encounters. Left-biased successful interactions. These observations provide first report reproductive under controlled conditions hold promise establishing reliable benchmarks assessing monitoring quality mass-produced individuals pest control efforts.

ABSTRACT Answers to the question of what characteristics allow animals thrive in human‐dominated environments remain elusive. Consistent interindividual differences or personalities can potentially explain functional significance habitat‐specific traits that enable coexist with humans. Rhesus macaques ( Macaca mulatta ) are most successful nonhuman primates Anthropocene, living diverse climatic and environmental conditions. Studying synanthropic rhesus macaques, is, those anthropogenic habitats, provide insights into biological facilitating their success. We planned a multi‐method “bottom‐up” approach behavioral observations novelty experiments, standardized for assessing captive primates, evaluate adult N = 52 ). Novelty experiments encountered significant challenges, limiting effectiveness. So, we continued form focal sampling, revealed two repeatable traits, subjectively labeled as social tension meekness . found an association sex tension, where males exhibited higher than females. In additional analysis, individuals obtained food through contact provisioning had scores trait noncontact provisioning. discuss how observed personality may offer adaptive advantages environments, despotic face both benefits costs (including social) setting. also emphasize protocols designed conditions not be directly applicable free‐living animals. The study underscores need reconsider obtain comparable measures between non‐captive populations. This would enhance ecological validity assessments.

Friendships, exhibited by both humans and non-human animals, have considerable adaptive benefits. In humans, similarity or homophily in personality is considered a proximate mechanism driving friendships, yet little known about the behavioural ′decision rules′ underlying animal friendships. Some empirical research suggests that friendships can be driven homophily. However, these studies are restricted to primates, limiting our understanding of mechanisms We investigated feral population water buffalo ( Bubalus bubalis ) determine whether drives this ′non-model′ social species free-ranging environmental conditions. conducted observations on females (n=30) assessed their personalities. Close spatial proximity served as indicator friendship, validated affiliative body contact. An objective ′bottom-up′ method revealed three traits – tension , vigilance general dominance . found with comparatively lower differences significantly higher close associations. did not find an effect kinship Our findings show form based homophily, decision rule attributed predominantly primates. discuss light socioecology but emphasise implications broader evolutionary context personalities

Abstract Animals regularly experience stressful situations, ranging from predation to social stress, yet successfully deal with them on most occasions. This adaptive mechanism, coping, reduces the adverse effects of stressors through behavioural and physiological efforts, failing which may result in reduced fitness. However, considerable variation coping is observed. Unlike humans, often considered a personality trait non-human animals due construct similarity, resulting conceptual ambiguity. Besides, limited multidisciplinary research has rendered comprehending drivers challenging. We assessed repetitive or styles ( n=30 ), emotional arousal n=12 consistent inter-individual differences, i.e., personalities n=32 ) long-tailed macaques Macaca fascicularis using observations, ecologically relevant experiments, infrared thermography. finally investigated association Valine/Methionine polymorphism encoded by Catechol-O-methyltransferase (COMT) gene n=26 widely known for its involvement human stress regulation. Our findings suggest that presence equivalent COMT Val 158 Met are associated ‘emotion-focused’ ‘problem-focused’ styles.
