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.

Migratory beekeeping can harm the bee colonies if not executed properly. Here, colonies of Apis mellifera were transported (for one or two hours) or not, following proper technical standards. To analyze gene expression (defensin-1, abaecin, and HSP70), forager bees were collected immediately, 24, and 72 hours after transportation. Bee mortality and population growth were measured before and after transportation. This study concludes that transporting honey bee colonies for 2 hours promotes immune system gene expression, although there are no significant changes in bee mortality and population growth of the colonies.

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.

Native to the Neotropics, Wasmannia auropunctata (Roger, 1863) has been unintentionally introduced around the world, heavily impacting native ant biodiversity, societies, and economies as well as human and animal health due to its potentially dangerous stings. Herein we report on the first record of W. auropunctata in Cyprus. Specimens were collected from plant nurseries and tourist facilities in Paphos and Limassol district. Wasmannia auropunctata is believed to spread via the horticultural pathway to locations with sufficient humidity. Further research is necessary to determine the distribution and assess possible negative impacts of W. auropunctata to native biodiversity, society, the economy and human health in Cyprus.

Colony defense by social wasps includes aggressive behavior and camouflage with a high diversity of adaptation of their nests to the environment, including substrate choice. The objective of this study was to present new data on nesting and colony defense by the Neotropical social wasps Metapolybia cingulata and Metapolybia docilis (Hymenoptera: Vespidae). Field observations were made on January 4th and 5th, 2022 at the State Park of Iguaçu, state of Paraná, Brazil, on M. cingulata and M. docilis nests and information on nesting of these wasps obtained in 2014 at the Pandeiros River Wildlife Refuge (REVIS), and in 2012 at the Rio Doce State Park, state of Minas Gerais, Brazil. The types of substrates used by M. cingulata and M. docilis reinforce the importance of nest camouflage as a defense strategy for their colonies. The selection of nesting sites by these species was very variable.

Until now, the occurrence of Pericapritermes ceylonicus (Holmgren) was not confirmed in the Indian mainland. Here, we document the occurrence of this species from Karnataka state constituting its first report from India. The species was identified based on the soldier caste, and the worker characters were described for the first time, including the digestive tube and enteric valve armature. The enteric valve was characterized by the presence of gradually reducing triangular spines. The study provides the basis for further taxonomic characterization of Pericapritermes occurring in India using gut morphology of workers.

This is the first record of gregarine infection in the worker midgut of the Neotropical termites Ruptitermes pitan and Ruptitermes reconditus. Gregarines have already been described in the gut and hemocoel in workers of other termite species, and although these protozoa are not able to kill these insects, they may affect their fitness. In the present study, gregarines were only observed in the gut lumen or linked to the midgut wall of termite workers. Histological sections of the worker midgut of Ruptitermes spp. showed three phases of the gregarine life cycle with the same individual worker displayed up to 4 gamonts and 2 trophozoites.

This novel review of analytical methods for pot-honey research was intended to provide concise references to a 35-day post-harvest experiments at 30 °C, in an integrated study. Diverse methods were selected from specialized literature, from the AOAC (Association of Official Analytical Chemists), and the International Honey Commission. Besides the geographical and seasonal origin, the pot-honey I.D. consists of entomological and botanical identifications, the latter performed by acetolyzed or natural melissopalynology. The methods of this integrative study included: 1. Physicochemical analysis (Aw, color, moisture, pH, free acidity, lactone acidity, total acidity, hydroxymethylfurfural (HMF), and sugars by highperformance liquid chromatography HPLC), 2. Targeted proton nuclear magnetic resonance 1H-NMR metabolomics (sugars, ethanol, HMF, aliphatic organic acids, amino acids, and botanical markers), 3. Biochemical composition (flavonoids, polyphenols), 4. Antioxidant activity (ABTS 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid-free radical scavenging assay, DPPH 2,2-diphenyl-1-picrylhydrazyl radical scavenging assay, ferric reduction assay FRAP), 5. Microbial counts (aerobic plate, yeast and mold, Bacillus, and lactic acid bacteria count), 6. Honey microbiome profiling via independent-culture method: high-throughput bacteria and fungi based on amplicon sequencing approaches, 7. Sensory evaluation (odor, aroma, taste, persistence), and 8. Honey authenticity and biosurfactant tests by an interphase emulsion. A further section was included to provide basic information on the results obtained using each method. This was needed to explain the interacting components derived from pot-honey processing within the stingless bee nest and post-harvest transformations.

Red wood ants are ecologically dominant species that affect the composition of the invertebrate community. In the past century, one of these species, Formica paralugubris (Seifert 1996), was introduced outside its native area (the Alps), in the Apennines (Italy). Here we investigated the effect of the presence of an introduced population of F. paralugubris on the frequency of nests of other ant species in Abetone, Central Apennines. Ant nests were found only in the area unoccupied by F. paralugubris. In this area, we also found one pleometrotic association between queens of Lasius flavus (Fabricius, 1782) and two plesiobiotic associations, one between Formica fusca (Linnaeus, 1758) and L. flavus and the other one between Myrmica ruginodis (Nylander, 1846) and L. flavus. This latter is the first plesiobiotic relationship reported between these two species, the second reported for M. ruginodis and the 10th for L. flavus. Additionally, this is the first plesiobiotic association reported for the Mediterranean region and Southern Europe.

Blepharidatta is a rare Neotropical ant genus in the Attini tribe of the subfamily Myrmicinae. It has only four valid species and among them Blepharidatta delabiei was recently described and there is little knowledge on its biology. This study is the first cytogenetic characterization for the genus Blepharidatta and also presents the biology of B. delabiei. Cytogenetic analyses revealed a karyotype 2n = 28 with acrocentric and metacentric chromosomes and a karyotypic formula (m: metacentric, a: acrocentric): 2K = 16m + 12a. We observed that ants of this species have diurnal habits with higher foraging activity in the afternoon and are possibly omnivorous as they accepted the baits used. The distance between colonies varied from 5 to 7 meters.
