The popular name refers to its size and the habits of the larvae, which frequently cut shoots of seedlings, causing severe injuries or death of the host plant. Despite its importance to crops management, the immature stages of this species were never described in detail; moreover, they are frequently confused with many other agrotines, specially with species of Feltia Walker, 1856 and Agrotis Oschenheimer, 1816. Therefore, this study aims to describe the external morphology and the tegument ultra-structure of the immature stages of Feltia repleta based on exemplars obtained from a female collected in Planaltina, Brasília, Distrito Federal, Brazil, whose larvae were fed with artificial diet. Descriptions of the morphology with illustrations are presented, based upon observations through scanning electron microscopy and stereoscopic and optic microscopes attached to a camera lucida. Descriptions and illustrations of the eggs, first and last instars head capsule, chaetotaxy, tegument, and setae, and both sexes pupae are presented and the morphological characters are discussed and compared with immature stages of other species of agrotines.

For this task, we evaluated the geographic distributions and the climatic niches of 47 endemic and cosmopolitan drosophilids occurring in subtropical regions of the Neotropics using raw climatic data from collection records and environmental niche models (ENMs). We showed that the studied species varied in two highly correlated properties: the distribution ranges and the environmental niche breadth. Moreover, significant differences were observed between endemic and cosmopolitan drosophilids in terms of variable importance and climatic niches. Most of the studied species are distributed in regions under mild climatic conditions, but there are many species inhabiting harsher environments. Generally, the results suggest that several Neotropical drosophilid species may be highly vulnerable to global warming, potentially serving as bioindicator species for assessing the impact of climate change.","PeriodicalId":19071,"journal":{"name":"Neotropical Entomology","volume":"54 1","pages":"60"},"PeriodicalIF":1.4,"publicationDate":"2025-04-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144020780","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}

Infestation of T. urticae is more prominent on eggplant which causes 50-80% yield loss if no control measures initiated. The economic threat posed by T. urticae is constantly increasing because of the development of pesticide resistance and resurgence. One of best alternative management strategies is use of plant-based pesticides like secondary metabolites and essential oils (EOs) which provides sustainable and long-term protection. In the present study, EO extracted from a billygoat weed, Ageratum conyzoides L. (Asterales: Asteraceae), and its binary compounds were evaluated against T. urticae. The A. conyzoides EOs showed highest mortality (97.5% with the LC50 10.61 µL/mL), due to the presence of Precocene I (32.32%), Geraniol (1.23%), and Neral (0.55%). Among the binary compounds, Geraniol (95%) showed highest mortality having LC50 (95%) of 9.59 µL/mL followed by Citronellol (77.5%) and Alpha-pipene (75%). Significant increase in the activity of esterases, glutathione S-transferase, and acetylcholine esterases contributed for the toxicity in T. urticae following exposure to essential oils (EO) and their binary compounds. SEM images revealed shrinking of the bodies of treated T. urticae along with reduced body measurements compared to the untreated individuals.

Euglossine bees, also known as orchid bees, are the primary pollinators of orchids in the Neotropical region, and little is known about the resilience of these communities to geographical formations. Combining phylogenetics with the community ecology makes it possible to evaluate the evolutionary relationships among coexisting species, and to associate the phylogenetic structure of the community with the niche overlap and historical events. Here, we evaluated whether the orchid bee communities differ phylogenetically by altitudinal range on each side of the Andean mountains. We collected euglossine bees using chemical attractants at three different elevation levels in two sites (Putumayo and Nariño) separated by the Andean cordillera. We captured 1225 bees belonging to 64 species and four genera. We found phylogenetic clustering in Low and High Nariño, in contrast to Putumayo and Mid Nariño, which tended toward a random draw. However, overdispersion was not recorded; hence, the role of environmental filtering and competitive exclusion in community assembly along elevation gradients remains unclear. Consequently, we propose that the emergence of the Northern Andes generated changes in the composition of orchid bee communities distributed sympatrically. The niche conservatism observed in Nariño is explained by the narrow zone and climatic homogeneity and randomness in Putumayo, by the extension of the territory and other geological events such as Pleistocene refugees and Amazon River formation.","PeriodicalId":19071,"journal":{"name":"Neotropical Entomology","volume":"54 1","pages":"58"},"PeriodicalIF":1.4,"publicationDate":"2025-04-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144025730","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}

Additionally, the extract caused a mortality rate of 78% at 10 μg/μL after 24 h, with an LC50 of 7.9 μg/μL against E. atomaria. The enzymatic activity of E. atomaria acetylcholinesterase was evaluated in vitro to reveal the mode of action, resulting in a 58% inhibition at 5.0 μg/μL. The main bioactive compounds in fractionated D. ambrosioides ethanolic extracts were identified by GC-MS. The extract contained high concentrations of thymol and carvacrol in the less polar fractions, which were the most active. The bioactivity of both compounds against E. atomaria was also tested, showing strong insecticidal activity with an LC50 of 1.6 and 1.4 μg/μL for thymol and carvacrol, respectively.

Over the past 20 years, microplastics have increasingly been recognized as a source of contamination in terrestrial ecosystems and the organisms that inhabit them. Some studies have reported that these contaminants can alter the intestinal microbiota of bees, which may also harm their immune system and, consequently, directly impact the health of these animals. These consequences can impair bees' ability to effectively carry out their foraging activities, potentially leading to the decline of the hive and negatively impacting the ecosystem services they provide through pollination. However, research linking microplastics to bees is still in its early stages. Therefore, this work conducted a systematic review, applying selection and exclusion criteria to studies published between 2000 and 2024 that mentioned bees or bee products in relation to microplastics. These publications were extracted from electronic databases (Google Scholar, Scielo, Scopus, PubMed, and Web of Science). With the keywords used, 920 works were found, of which 33 met the pre-established review criteria, produced between 2013 and 2024, most of them from Italy (six studies) and China (five studies).

We employed the Winkler extractor to collect litter ants in fifteen eucalyptus stands, ranging in age from 1.5 to 10.3 years. Our findings revealed the presence of fifteen ant guilds. The guild of small arboreal ants with massive recruitment exhibited a decline in species richness as the understory matured, while the guild of specialized predatory cryptic myrmicines demonstrated an increase in species richness in older stands. Camponotus crassus Mayr and Wasmannia auropunctata Roger were more prevalent in younger understory stands, whereas Pheidole fallax Mayr was predominantly found in native vegetation. Ants can serve as indicators of environmental conditions in eucalyptus plantations and contribute to environmental certification efforts. Our results demonstrate that eucalyptus plantations with understory vegetation effectively support the conservation of ant species over time, providing habitat for diverse ant guilds that utilize the available resources in this environment and may act as a species source for the surrounding landscape.","PeriodicalId":19071,"journal":{"name":"Neotropical Entomology","volume":"54 1","pages":"55"},"PeriodicalIF":1.4,"publicationDate":"2025-04-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144030095","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}
