Leaf-cutting ants manage their waste continuously to avoid risks of colony contamination. The presence of residues or their odor near foraging areas is enough for ants to stop attacking plant tissues. However, to date, no study has demonstrated an interspecific effect of nest waste on the deterrence of leaf-cutting ants. Here, we tested whether a hydroalcoholic extract of nest refuse (NR) of the leaf-cutting ants Acromyrmex balzani Emery, 1890 and Atta opaciceps Borgmeier (Hymenoptera: Formicidae, Attini) causes an interspecific deterrent effect. Field colonies of Ac. balzani (n = 30) and A. opaciceps (n = 36) were used. For each colony, we offered baits made with plastic straws covered by citrus pulp and sprayed with a hydroalcoholic solution of 20% (vol/vol) alcohol/water (Control) or an extract of 20% (vol/vol) of NR from Ac. balzani and/or A. opaciceps. Over 20-30 minutes we recorded the amount of baits removed and data were compared through survival analysis and Linear Mixed Effect (LME) model. Ants avoided collecting baits sprayed with NR resulting in less than 20% of these baits being carried to the nest versus 80% of control baits. The deterrence was both intra and interspecific, considering that the response was similar for baits from both species. Such results reinforce the premise that the presence of nest refuse alters the foraging behavior of ants and paves the way for new studies that can verify its effectiveness in reducing foliar consumption on a larger spatial scale.

The gut microbiota of vertebrates and invertebrates has become the focus of recent research. However, current sterilizing practices need more systematic quantitative methods due to limitations caused by their minute body size. Thus, an effective sterilization process incorporating organic and inorganic methods to obtain invertebrate microbiota, particularly when evaluating smaller insects, has yet to be elucidated. This study investigated if the whole abdomen should be utilized as the material to sterilize and examined whether physical and chemical surface sterilization methods could be combined to facilitate the acquisition of gut microbiota from theimported red fire ant (Solenopsis invicta Buren, 1972). Eight methods were designed by incorporating three chemical reagents (sterile water, 2.0 mg/L NaClO, and 75% ethanol) and one physical treatment (250 nm UV). The length range of the amplified fragment in the red imported fire ant is 401-450 bp. According to the results of the GLM regression model and interaction effect model, none of these factors (sterile water, 2.0 mg/L NaClO, and 75% ethanol, 250 nm UV) were significant for statistical regression of the Chao index, and these factors did not significantly interact with each other. Based on Alpha and Beta diversity analysis, none of the methods significantly affected the diversity of insects’ gut microbiome. Finally, we suggested that it is feasible for different species of small insects to select appropriate methods according to the current situation. Still, it is best to achieve unity in the same group.

The myrmicine ant genus Cardiocondyla consists of around 80 species of small, inconspicuous ants, which live mainly in subtropical and tropical Africa, Eurasia, and Australia. Several species have been accidentally introduced to America and have also invaded numerous originally ant-free islands around the world. The diversity of life histories in this genus, with lethally fighting wingless males, dominance hierarchies among queens, and considerable variation in the sociogenetic organization of colonies across species, has made it an interesting model to investigate the evolution and behavioral ecology of reproductive strategies. Taxa of the African Cardiocondyla shuckardi group are of particular interest, as in a phylogeny they lie between facultatively polygynous species with fatal male competition and monogynous species with mutually tolerant males. Studies on male behavior and sociogenetics in C. “venustula,” a widespread member of the C. shuckardi group, showed that males defend small territories inside their subterraneous nests. At the same time, they revealed a surprisingly large variability in mtDNA haplotypes both within and between populations in South Africa, Angola, and Côte d’Ivoire. As the different lineages are very similar in morphology and nuclear markers, more research is needed to clarify the very confused taxonomic situation in this fascinating group of ants.

To illustrate the essential role of Apis cerana Fabricius in plant pollination, a survey was conducted using PCR, DNA barcoding, and high-throughput sequencing technologies to assess the diversity of plants foraged by A. cerana at five sites around Qinling Mountains. A fragment of the rbcL gene in pollen isolated from honey collected at each site was amplified and sequenced. The results show that samples BJ and TC, samples FP and AK have a high correlation, respectively. According to the information of a total of 64 plant species identified in the five sites, belonging to 53 genera, 37 families, and 23 orders, it is found that there is a relatively high diversity and complex composition of nectar and pollen plants and that most of the plants are sporadically available. The identified species show higher occurrence in some orders, such as Sapindales, Rosales, etc. There are significantly more plants of temperate origin than those of tropical origin, 58.5% and 34.0%, respectively. Some species of Rosales or Sapindales are more visited by A. cerana, with Toxicodendron vernicifluum (Stokes) being the dominant species. These results provide a basis for assessing the role of A. cerana in plant pollination and maintaining biodiversity.

Cuticular hydrocarbons of some Dolichoderinae species from France and various places like Spain, North Africa, and Italy were studied. The Tapinoma nigerrimum group was particularly analyzed and replaced in the genus Tapinoma. All species were correctly discriminated and a new hydrocarbons profile was found in Spanish mountains in the T. nigerrimum group, which was provisionally named T. sp. Spain. We added numerous unknown spots for the distribution of these ants. We also tested aggression between some T. magnum colonies and it appeared that this species forms supercolonies like other invasive species, but does not form giant supercolonies like the Argentine ant

Parachartergus wasps are known by having a very aggressive behavior, especially the large black species with white wings tip, which have painful stings. They exhibit a unique and interesting characteristic, the capacity to venom spraying during the colony defense or self-defense. However, for the Amazonian species Parachartergus fulgidipennis (de Saussure, 1854), little is known about its behavior and nesting. In this way, we tracked and described the nesting site, the numbers of combs, and performed an ad libitum method to record behavioral activities. The nest was fixed vertically on a man-made concrete column, 1.2 m above the ground, measuring 25.0 x 6.0 cm and contained four combs with approximately 74 cells, with 31 eggs, seven larvae, 30 pupae, and almost 42 adults. With a flat thin grayish envelope with weak corrugations, the nest is very similar to the color of the substrate which turn in to really cryptic. The colony defense behavior presented by this species is unaggressive and very docile, suggesting that is not similar as observed for other Parachartergus species.
副脉蜂以其非常具有攻击性的行为而闻名，尤其是那些有着白色翅膀尖的大型黑色物种，它们的翅膀上有痛苦的刺。它们表现出一种独特而有趣的特征，即在群体防御或自卫时喷射毒液的能力。然而，对于亚马逊地区的物种——翼龙(parartergus fulgidipennis, de Saussure, 1854)，人们对其行为和筑巢知之甚少。通过这种方法，我们对筑巢地点、梳子数量进行了跟踪和描述，并对行为活动进行了随意记录。巢垂直固定在人造混凝土柱上，距地面1.2米，尺寸为25.0 x 6.0厘米，包含4个蜂巢，约74个细胞，31个卵，7个幼虫，30个蛹和近42个成虫。有一个扁平的薄灰色的信封，带有弱波纹，巢的颜色非常类似于基材的颜色，这就变成了真正的神秘。该物种的群体防御行为是非侵略性的，非常温顺，这表明它与其他副动脉蜥不同。

Colony multiplication of stingless bees, Tetragonula iridipennis, largely relies on the eduction of wild colonies from their natural nesting sites in India. During the hiving of wild colonies, colonies were destroyed with the loss of robust wild foragers and built-in storage reserves over the years. The present study was conducted to devise a technique to sustainably multiply the colonies of stingless bees from the wild colony and the colony establishment and development during the eduction process. The annexure hives provided for eduction were accepted in a shorter time (3.25 ± 1.18 days), with the construction of storage pots observed at 7.75 ± 1.59 days after hive acceptance by the bees. The movement of foragers between the wild colony and the annexure hives was noticed for 13.80 ± 4.20 days. The foragers settled in the annexure hives and started foraging after 18.20 ± 2.49 days. The advancing fronts were observed at 26.67 ± 2.58 days after the addition of the laying queen in the established annexure hives. There was a significant increase in the number of inhive workers after the queen seeding in the annexure hives. This technique is the easiest and most sustainable non-destructive way of multiplication of stingless bee colonies without loss in viability of the perennial wild colony.

This study investigated the morphometric variation in Melipona scutellaris stingless bees rational hive boxes from five states, inserted into the natural range of the species occurrence in northeastern Brazil. The cluster analysis (UPGMA) showed three distinct groups by determining the cutoff point. The multivariate analysis were performed using MANOVA and Canonical Variables for the shape analysis. The One-Way ANOVA was used to assess differences in centroid size. The results showed population divergence between localities limited by geographical barriers or great distances, corroborating previous observations by the UPGMA. Variation between colonies inter-state was higher that intra-state and, in most cases, Geometric Morphometrics was effective in identifying the origin of colonies transported to other states, observed in the cross-validation analysis that showed more than 70% of classification accuracy. Geometric Morphometrics could be used to evaluate the introduction of colonies within the kindred meliponary. Natural populations of Melipona scutellaris show a significant variation, which brings important implications to meliponiculture and to conservation strategies for this endangered species.

Since some social wasp species are sensitive to environmental changes and can be used as bioindicators, the objective of the present study was to analyze the variation in the fauna of social wasps during the phases: before, during, and after completion, as well as to validate the use of wasps as a tool for monitoring the impacts generated by the implantation of the Botanical Garden of the Federal University of Juiz de Fora. Social wasps were sampled through active searching methods, searching for nests and attractive traps in the years 2011 and 2012 (before the construction), 2013, 2014, and 2016 (during the construction), and 2019 (after the construction and opening of the Botanical Garden). The richness and similarity of the species varied over the years, and it was possible to identify resistant and sensitive species to the impact caused by the implantation of the Botanical Garden. Studies with social wasp fauna conducted over many years in the same area can be an efficient tool in monitoring impacts; in addition, it is necessary to have a partnership between researchers and the management of the enterprises to mitigate the effects caused by guidelines and environmental education.
