Even so, temperatures in the brood region are usually above temperatures in the nests’ periphery, which cannot be explained through passive thermoregulation alone. In the present study, we investigated temperature variations in nests of Melipona scutellaris throughout the year as well as the effective contribution of brood thermogenesis to the thermal dynamics under experimental simulations. The incubation temperatures in this stingless bee species varied significantly with ambient laboratory temperature. Thus, despite a constant temperature excess in the brood area, colonies did not control incubation temperature in a strict homeostatic manner but rather showed a heterothermic behaviour. At ambient temperatures of 25–32.5 °C, brood thermogenesis increased the temperature in the combs’ close surroundings by up to 4 °C, therewith explaining part of the temperature excess in the brood area. The residual thermal increase by almost 7° at ambient temperatures of 15 °C was, presumably, attributed to active heating by the adults. The elevated metabolic activity of the pupae between 25 and 32.5 °C suggests a lower thermal range for brood development in M. scutellaris. The adaptive advantages of both colony heterothermy and reduced incubation temperatures in the threatened native habitat of this stingless bee species, the Atlantic Rainforest in north-eastern Brazil, are discussed.","PeriodicalId":13573,"journal":{"name":"Insectes Sociaux","volume":"4 1","pages":""},"PeriodicalIF":1.3,"publicationDate":"2024-04-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140571682","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Yet, several studies have revealed low colony activity levels and a subgroup of specialized inactive individuals, raising questions about their role. This study investigates whether these inactive ants differ in their sensitivity to environmental cues compared to other worker groups. We monitored the behavior of individually tagged workers from Myrmica rubra ant colonies, categorizing them as foragers, nurses, domestics, or inactives. Approximately one-third of the workers exhibited high levels of inactivity, forming a distinct group that remains stable over several days. Subsequently, individual tests were conducted on these ants to compare their responses to intranidal or extranidal location cues, and to task-related stimuli such as larvae or prey. In individual tests, foragers displayed distinct responses compared to internal workers. They exhibited greater responsiveness to prey, but were less inclined to care for larvae, stay in colony-marked or shaded areas, or approach nestmates. Among internal workers, except for the inactive ants, responses to various stimuli did not significantly differ. Notably, inactives had a stronger attraction to colony odor and were more likely to carry larvae when compared to foragers. Our results suggest that the inactivity of some individuals is not due to a lack of sensitivity to surrounding stimuli. Furthermore, their high propensity to interact with larvae supports the hypothesis of a “reserve caste” function, where these workers become active during periods of increased colony workload.","PeriodicalId":13573,"journal":{"name":"Insectes Sociaux","volume":"23 1","pages":""},"PeriodicalIF":1.3,"publicationDate":"2024-04-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140571497","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Previous research has focused extensively on the evolution of front-line defense strategies that allow social groups to successfully avoid detection by enemies, defeat them during an attack, or mitigate fitness losses upon successful invasion. However, in the case of social insects, we must also consider how colonies have evolved to alter their behavior when they survive attacks. During an attack, colony fitness can be negatively affected while the colony itself survives. There may be selective pressure for surviving individuals to respond strategically to decrease the risks of future attacks by the same enemy. In this study, we tested whether colonies of Temnothorax longispinosus acorn ants emigrate when they experience a raid by the obligate social parasite T. americanus. We found that T. longispinosus colonies that experienced a raid moved to a different nest of equal quality significantly more than genetically matched colonies that had not experienced a raid event. We also found that raided colonies moved significantly more than we would expect by random chance. This result suggests that emigration may be an induced defense against re-raiding in this host-parasite system.","PeriodicalId":13573,"journal":{"name":"Insectes Sociaux","volume":"10 1","pages":""},"PeriodicalIF":1.3,"publicationDate":"2024-04-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140571513","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These nests provide protection and food in a temperature- and humidity-stable environment, which attracts numerous organisms that live in association with these social insects. The interactions between ants and some myrmecophilous groups, such as coleopterans and lepidopterans, have been widely studied, while other groups, such as gastropods, have received less attention. In this study, we present observations of the interactions between the Neotropical ponerine ant Neoponera verenae and terrestrial gastropods. We found 56 individuals belonging to four families, seven genera, and eight species of terrestrial gastropods in ant nests established in three types of substrates (dry cocoa pod, soil, and decaying wood trunk) in the Atlantic Forest Biome. The most frequent genera were Allopeas and Leptinaria (Achatinidae), which accounted for 57.1% of the observed specimens. The gastropods mainly used the shelter provided by ant nests, their favourable and stable microclimatic conditions, and the abundant food resources stored in waste chambers. Young and adult individuals of Leptinaria sp. were found in ant nests, but no aggressive or predatory behaviours were recorded in interactions between ants and gastropods. Our study includes unpublished records of ant nest commensals and presents hypotheses on the close interactions between gastropods and ants.","PeriodicalId":13573,"journal":{"name":"Insectes Sociaux","volume":"11 1","pages":""},"PeriodicalIF":1.3,"publicationDate":"2024-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140571687","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, we explore the role that scientists play through their interactions with the media in shaping our attitudes towards one of the least appreciated insects—the aculeate (stinging) wasps. Vespine wasps are an excellent taxonomic group for such a study as they are important predators in native ecosystems (e.g., the Northern Hemisphere—in Europe and North America) but ecologically devastating as invasive species in many regions of the Southern Hemisphere (e.g., New Zealand, Australia, South America). Despite this, global media coverage of wasps invariably focuses on and emotively exaggerates the negative defensive stinging behaviour of wasps, and almost entirely overlooks their beneficial positive roles (as pest controllers and pollinators). Wasp and bee scientists from around the world were surveyed about their interactions with the media and how they considered these interactions to influence public perceptions and insect conservation. Our surveys capture the negative-wasp and positive-bee biases experienced by scientists through their interactions with the media. We consider the implications of such biases on wasp populations, their conservation and management, and make recommendations for a more balanced portrayal of this important and diverse group of insects.","PeriodicalId":13573,"journal":{"name":"Insectes Sociaux","volume":"284 1","pages":""},"PeriodicalIF":1.3,"publicationDate":"2024-03-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140099319","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Social wasps, including Vespula species (the yellowjackets), must crucially decide to transition from colony growth to reproductive production before the onset of winter. The timing of this transition could be influenced by worker numbers and environmental factors that affect the fitness of the colony. Early initiation of reproductive production has the advantage that a few reproductives can emerge if the colony collapses prematurely. In contrast, once reproductive production begins, nest growth terminates and the increase of future reproductives should be limited. This study investigated the group decision-making process regarding when and under what circumstances Vespula shidai initiates its reproductive phase. During the early reproductive period, we estimated the number of workers and new queens that emerged from the meconia in the cells. Significantly, a positive correlation was observed between the number of workers and the production of new queens during the early reproductive period. To examine the benefits of early reproduction, we reared V. shidai colonies in a plastic greenhouse, allowed males and new queens to fly and mate freely, and allowed the queens to begin overwintering at their timing. In our experimental environment, new queens that emerged earlier in the reproductive period had a higher survival rate during overwintering and higher dry and fat weights in the following spring. The higher dry and fat weights of the queens suggested better survival during the founding phase of the nest.","PeriodicalId":13573,"journal":{"name":"Insectes Sociaux","volume":"31 1","pages":""},"PeriodicalIF":1.3,"publicationDate":"2024-03-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140044362","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This may be especially true for haploid organisms that are susceptible to any deleterious alleles inherited from their parent and any that arise over their lifetime. Unfortunately, little is known about the rate of somatic mutation accumulation across individuals and tissues of haplodiploid animal populations, the functional processes through which they arise, and their distribution across tissues and the genome. Here, we generated short-read whole-genome sequencing data for four tissues of haploid honey bee males. We paired this with estimates of telomere length and tissue-specific DNA content to address three major questions: is there variance in somatic mutational load across haploid individuals and specific tissues therein, does increased DNA content in a tissue contribute to somatic mutational load, and does telomere length correlate with mutational load? Our results suggest that variance in somatic mutational load is better captured across individuals than across tissues, that tissue-specific DNA content is not associated with somatic mutation load, and that variance in telomere length does not correlate with somatic mutation loads across tissues. To our knowledge, this is the first observational study on somatic mutational load in Apoidea and likely Hymenoptera. It serves as a useful advent for additional studies understanding the processes through which haploids tolerate or repair somatic mutations.","PeriodicalId":13573,"journal":{"name":"Insectes Sociaux","volume":"29 1","pages":""},"PeriodicalIF":1.3,"publicationDate":"2024-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140032862","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This is because of the well-understood algorithms workers use to select nests during relocation. However, the details of these algorithms are based on data from relatively few species. This taxonomic neglect threatens to provide a distorted sense of how colonies in general execute collective decision-making and the obscure variation in algorithms that can be used to accomplish this task. We observed nest relocations in 18 species of acorn ants and compared our data to previously collected data from emigrations in T. curvispinosus to obtain a more thorough survey of nest relocation behavior in this group of ants. We found that the basic sequence of emigration behaviors in most species was no different from those reported in previous studies. However, we found a few notable deviations from standard Temnothorax emigration behavior that appear to be common in Leptothorax. Compared to Temnothorax, species of Leptothorax showed elevated rates of worker participation in scouting for a new nest and fewer adults were carried to the new nest. This difference could not be explained by colony size, the latitude of colony origin, or whether colonies were social parasites that captured workers from colonies of other species. Furthermore, we found that the timing of transports in Leptothorax is structured so that brood transports are prioritized; adults are carried to the new nest near the end of emigrations after all brood items have already been relocated.","PeriodicalId":13573,"journal":{"name":"Insectes Sociaux","volume":"22 1","pages":""},"PeriodicalIF":1.3,"publicationDate":"2024-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140007606","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
