Mites have long been associated with bees, often showing a close relationship with particular taxa, probably due to a co-evolutionary process. The present study is the first confirmation on the occurrence of the mite species Calvolia summersi (Mostafa, 1970) in India and its association with Xylocopa fenestrata (Fabricius, 1798), a large carpenter bee species. The mite species was previously reported from Brazil in association with Zethus, a neotropical potter wasp genus. C. summersi is isolated and studied from different populations of X. fenestrata in Sagar Islands, West Bengal, the biggest island of mangrove Sundarban deltaic complex. A literature-based review of the Xylocopa-mite associations from India is provided herewith to understand the diversity and pattern of mite species on Xylocopa host selection in the country. Instigating a baseline study of Xylocopa-mite association is recommended to demark the status of dynamism for better conservation and protection.

The African species Xylocopa pubescens Spinola (Hymenoptera, Apidae) has recently stabilized in some European countries such as Cyprus, Greece, and Spain. Wood transportation and climate change are the main hypotheses for the spread of this non-native bee in Europe. I present the first record in the literature from Santorini and the Aegean Archipelago, confirming the Citizen Science data from different websites. The presence and the spread of this species in Europe are discussed.

Nannotrigona testaceicornis (Lepeletier, 1836) is a stingless bee with wide distribution in the Brazilian territory. Despite its importance in meliponiculture and pollination, there are still few behavioral studies related to the species. The aim of this work was to characterize the recognition and defense behaviors in intraspecific bioassays carried out in N. testaceicornis colonies. Intra and inter-colonial bioassays were carried out with six colonies from different locations. The number of occurrences of each behavioral act, latency measures, and duration of confrontations were quantified. An ethogram with eight behavioral acts and two categories was elaborated. The acceptance rate was significantly higher in intra-colonial confrontations and the rejection rate was higher in inter-colonial confrontations. The rejection process was significantly higher than the acceptance process, which may be related to the specific behavioral repertoire of each process. Results indicate that the presence of an intraspecific intruder triggers an aggressive response from guards positioned in the colony access tube.

The process of human-induced forest fragmentation increases the degree of isolation and causes biodiversity loss. Abrupt changes occur mainly near the edge of the fragment, where the average temperature is relatively higher and the humidity is lower. However, some natural environmental characteristics, such as higher air moisture in riparian areas, may buffer or minimize the edge effects. Here, we studied how the edge effect may affect ant species diversity and functional composition on valleys dissected by small streams (mesic areas). We categorized ant assemblages into the functional groups based on foraging, nesting habits, natural history information, and phylogeny. Ants were sampled using pitfalls and the Winkler extractor in ten riparian plots in a fragment of the Central Amazon. We individually fit the ant species richness, occurrence, and composition against two edge measures: forest edge distance and road-building distance. We recorded 99 species/morphospecies. Forest edge distance and road-building distance did not influence the occurrence and number of ant species per plot but were related to ant species composition. Moreover, there was not a clear pattern between functional groups distribution, except by leaf-cutters and generalist omnivorous species. Our results suggest a limited effect of forest edge distance and road-building distance on ant diversity

Among ants, plesiobiotic associations are defined as occasional or regular nesting of heterospecific colonies in close proximity and without any biological interdependence. Habitats with a scarcity of available nesting microhabitats and ecological dissimilarity between the involved species are supposed to favor the frequency of plesiobiosis. In the last review published on this topic, the authors summarized all the plesiobiotic species pairs reported in the literature for the Holarctic region, listing 48 species pairs. On the basis of our field investigation in the Mediterranean island of Sicily (Italy), we are able to report additional 81 plesiobiotic ant-ant species pairs, two associations of three ant species, and four ant-termite pair associations. We suggest plesiobiosis to be severely underreported rather than rare, at least in the Mediterranean region.

We studied the seasonality and made notes about the nesting habits of the endemic social wasp Polistes ridleyi Kirby, 1890 of the Fernando de Noronha Archipelago. We collected 427 adult paper wasp P. ridleyi specimens for nine months using Malaise interception traps. The highest abundance of wasps was observed in October, November, and December, a fact most likely explained by the lowest precipitation levels on the island. We recorded 38 P. ridleyi nests. However, most of them were collected in a single Cynophalla flexuosa (L.) plant. This agglomeration may suggest multi-combs behavior, as reported for another species of Polistes spp.

The foraging activity can be defined as the search for food resources and is an activity of utmost importance for ant colony maintenance. Workers can be exposed to adverse environmental conditions during foraging, and because of it, some species can adjust their foraging behavior to achieve greater success in the search for resources. The foraging behavior has been studied in other ant species; however, studies with the Cephalotini tribe are still scarce in the literature. In this study, we evaluated how Cephalotes borgmeieri (Kempf) foragers adjust their foraging activity to variations in abiotic factors. Throughout the day, the flow of foragers is positively influenced by temperature and luminosity and negatively affected by relative air humidity. Wind speed does not affect the flow of foragers. During the day, we can observe four groups of activity intensity: very low, low, medium, and high. The foraging peak occurs at the hottest and least humid times of the day

The Hymnoptera order includes several flower-visiting insects (e.g. ants, bees, and wasps) and the coexistence of many different species in the same community can generate interspecific competition. Notwithstanding shared communities, research which evaluates how these taxonomic groups influence a whole community of flower-visiting Hymenoptera is lacking. Moreover, abiotic factors can also impact these floral visits, because each organism responds differently to climatic variations. The goal of this study is to evaluate abiotic factors, specifically relative air humidity and air temperature, which may be able to impact the number and the frequency of interactions between hymenopterans and flowers and to assess the composition and niche organization, by making use of interaction networks, of the entire community of flower-visiting Hymenoptera at the botanical garden of the Universidade Federal Rural do Rio de Janeiro. For the duration of a year, we took samples in that botanical garden, compartmentalizing the collections temporally in accordance with the time of the insects’ shift (morning or afternoon). We observed a positive influence of air temperature on the number of ant interactions and visits. It is also possible to observe that most of these interaction networks exhibited a nested and non-modular pattern and an average level of network specialization. In addition, bees stood out as the species with the highest frequency of visits and with the most generalist behavior. This study demonstrates how a botanical garden can sustain a diverse community of floral visiting Hymenoptera in an urban environment and why it consists in an important tool for biodiversity conservation.

Reliable drywood termite detection in structures is challenging but is critical for effective management. A microwave-based non-destructive method was evaluated for detecting termite activity. This study evaluated factors affecting the ability of this device to reliably detect Cryptotermes brevis in timber. The device displayed a high probability of successfully detecting C. brevis in naturally infested boards. The system detected termites 97% of the time when used at the highest sensitivity level, while producing few false positives. The number of termites did not affect detection ability, and detectable signals were produced even when a single termite was present. Detection success decreased with both increasing wood density and testing perpendicular to the grain in abrupt transition timber species. The device detected termites to a maximum depth of 45 mm in southern pine (Pinus spp.), but sensitivity declined with increased wood density with the detection limit declining to only 20 mm in denser Tasmanian oak (Eucalyptus spp). The device could only detect termites in samples with densities between 392 to 511 kg/m3 in 38 mm thick radiata pine samples. The results support the ability of microwaves to reliably detect C. brevis in timber.

The state of the art of Formicidae biogeographic studies using distribution modeling tools was reviewed. We aimed to evaluate how and for what purpose such tools were used in ant studies, as well as detecting modeling methods, algorithms, and variables selected for these studies. We analyzed papers published from 2001 to 2021 and focused on predicting invasion risks, conservation, and potential distribution of species. We also considered the mechanistic and correlative approaches, types of algorithms, and environmental variables. We observed that modeling is first used to predict invasion risks before conservation. The correlative approach was the most used, although it does not consider biotic or physiological aspects as the mechanistic approach does. The most used algorithm was Maxent, combining data set of occurrences with climatic variables. Nine studies used combinations of algorithms with consensual models. Research using modeling has been conducted more and more. However, it remains still incipient, mainly regarding conservation, as the current distribution of most of the Formicidae species is not well known. Although not frequently used in ant studies, distribution modeling represents an important approach for research in biogeography, ecology, and related areas. Certain perspectives could be useful, for example, for studying climatic changes, since possible variations in ant distributions, if anticipated, could suggest or guide further investigations or decision-making in public policies.

Certain perspectives could be useful, for example, for studying climatic changes, since possible variations in ant distributions, if anticipated, could suggest or guide further investigations or decision-making in public policies.","PeriodicalId":21971,"journal":{"name":"Sociobiology","volume":" ","pages":""},"PeriodicalIF":0.9,"publicationDate":"2022-12-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47830977","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
