Tetranychus urticae individuals and the proportion of infested plants were counted daily for the first 5 days, then every 3 days until day 29. All tested densities of N. californicus reduced T. urticae infestation; however, only the release of 5 or 10 predators per 50 T. urticae individuals resulted in infestation levels below the economic threshold level (ETL) recommended for controlling the two-spotted spider mite in cotton crops.","PeriodicalId":19071,"journal":{"name":"Neotropical Entomology","volume":"54 1","pages":"65"},"PeriodicalIF":1.4,"publicationDate":"2025-05-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144012160","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}

The widespread use of Bt soybean has achieved regional suppression of key lepidopteran pests and reduced insecticide use, providing economic and environmental benefits for all in Brazilian agriculture. Due to the high efficacy of Bt soybean in controlling key soybean lepidopteran pests and the simplicity of its use, most soybean farmers have adopted Bt soybean in extensive areas, reaching 94% adoption in the 2023/2024 crop season. However, the high adoption of Bt soybean associated with low refuge compliance has led to the first cases of pest resistance to Cry1Ac (Crocidosema sp. and Rachiplusia nu) in Brazil, representing major challenges to the future of this technology. Unfortunately, farmers wrongly believe that non-Bt soybean cultivars cannot be as profitable and productive as Bt soybean cultivars. Therefore, more than 10 years after Bt soybean adoption in Brazil, this review discusses the most important benefits and challenges of Bt soybean use and what can be expected for the next decade of this technology.","PeriodicalId":19071,"journal":{"name":"Neotropical Entomology","volume":"54 1","pages":"61"},"PeriodicalIF":1.4,"publicationDate":"2025-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144020779","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}

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.
