Beauveria bassiana (Bals.-Criv.) Vuill. is an established biocontrol agent in laboratory, but studies have shown negative effects of temperature and Ultraviolet radiation on its potential in vitro. Nevertheless, there is a lack of studies about its endophytic colonization in vivo, especially in field conditions in cowpea [Vigna unguiculata (L.) Walp.]. In this sense, this study aimed to evaluate the effects of B. bassiana applied to cowpea seed on the growth of the plants under laboratory and field conditions, and on their resistance to insect attack. Cowpea seeds were treated with suspension of 5 x 108 conidia/mL of B. bassiana. The plants were cultivated in two independent conditions (laboratory and field). The resistance to attack of the pest in field conditions was assessed by monitoring weekly the plants three times a week during 12 weeks, from the initial vegetative to the reproductive stage. According to the results, in laboratory conditions, there were significant differences among the inoculated and control plants for the variables of height of the plants (31.17 cm for treatment and 23.00 cm for control plants) and dry mass of the root (2.38 g for treatment and 0.97 g for control plants). In field conditions, the observed pest insects were miner fly [Liriomyza sp.] (Diptera: Agromyzidae), Cerotoma arcuata Olivier, 1791 (Coleoptera: Chrysomelidae), aphid (Aphis craccivora Koch, 1854) (Hemiptera: Aphididae) and the polyphagous hemipteran [Crinocerus sanctus (Fabricius, 1775)] (Hemiptera: Coreidae). The treated plants were less affected than control plants by these pests, especially at the beginning of the vegetative phase.
Beauveria bassiana (Bals.-Criv.) Vuill. 是一种成熟的实验室生物控制剂，但研究表明温度和紫外线辐射对其体外潜力有负面影响。然而，目前还缺乏对其体内内生定殖的研究，尤其是在豇豆（Vigna unguiculata (L.) Walp.）的田间条件下。因此，本研究旨在评估在实验室和田间条件下，将 B. bassiana 应用于豇豆种子对植物生长及其抗虫害能力的影响。用每毫升含 5 x 108 个 B. bassiana 分生孢子的悬浮液处理豇豆种子。植物在两种独立的条件下（实验室和田间）生长。在田间条件下，通过在 12 周内每周三次对植物从最初的无性繁殖阶段到生殖阶段进行监测，来评估植物对害虫侵袭的抗性。结果显示，在实验室条件下，接种植株和对照植株在植株高度（处理株 31.17 厘米，对照株 23.00 厘米）和根部干重（处理株 2.38 克，对照株 0.97 克）这两个变量上存在显著差异。在田间条件下，观察到的害虫有潜蝇[Liriomyza sp.]（双翅目：Agromyzidae）、Cerotoma arcuata Olivier, 1791（鞘翅目：Chrysomelidae）、蚜虫[Aphis craccivora Koch, 1854]（半翅目：Aphididae）和多食性半翅目昆虫[Crinocerus sanctus (Fabricius, 1775)]（半翅目：Coreidae）。与对照植物相比，处理过的植物受这些害虫的影响较小，尤其是在无性繁殖初期。

Neonicotinoid insecticides can cause a reduction in feeding rate, locomotion, and behavioral changes such as a reduction in flight speed and distance traveled by adult bees. Chronic exposure to sublethal concentrations can result in behavioral disorders and memory loss. This study investigated the effects of insecticides on Amazonian stingless bees, evaluated whether Melipona interrupta Latreire, 1811, is sensitive and does not reject food contaminated with Thiamethoxam, and compared the effects on native stingless bees from the northern region to Apis mellifera. Mortality was evaluated in these bees when exposed to Tiamethoxam (absolute standard AS and Actara 250 WG - commercial product) and Dimethoate AS as a positive control, thus verifying the lethal concentration 50 (LC50) for the species M. interrupta, popularly known as jupará. The mortality of forager workers exposed to active ingredient formulations indicated an LC50 of 24.77 ng/μL for Dimethoate, validating the tests, and 1.28 ng/μL for Tiamethoxam AS and 1.22 ng/μL for Actara 250 WG, values much lower than those found for A. mellifera bees, which were 4.28 ng i.a./µL of Tiamethoxam. Therefore, we concluded that formulations with the active ingredients Dimethoate and Tiamethoxam are highly toxic to Amazonian bees of the species M. interrupta.
新烟碱类杀虫剂可导致成蜂摄食率下降、运动和行为改变，如飞行速度和飞行距离减少。长期接触亚致死浓度的杀虫剂会导致行为紊乱和记忆丧失。本研究调查了杀虫剂对亚马逊无刺蜂的影响，评估了 Melipona interrupta Latreire, 1811 是否对噻虫嗪敏感且不会拒绝接受被噻虫嗪污染的食物，并比较了杀虫剂对北部地区本地无刺蜂和Apis mellifera的影响。评估了这些蜜蜂接触噻虫嗪（绝对标准 AS 和 Actara 250 WG--商业产品）和作为阳性对照的乐果 AS 后的死亡率，从而验证了 M. interrupta（俗称 jupará）物种的致死浓度 50（LC50）。觅食工蜂接触活性成分制剂后的死亡率表明，乐果的半数致死浓度为 24.77 纳克/微升，验证了测试结果；噻虫嗪 AS 的半数致死浓度为 1.28 纳克/微升，Actara 250 WG 的半数致死浓度为 1.22 纳克/微升。因此，我们得出结论，含有活性成分乐果和噻虫嗪的制剂对亚马逊蜜蜂 M. interrupta 具有剧毒。

Hesperinus Walker, 1848, a member of Bibionidae (Diptera), is a Holarctic and Oriental genus. The genus has been reported from the Neotropical Region twice: i) Hesperinus conjungens Schiner, 1868, transferred to Plecia Wiedemann, 1828 by Hardy in 1967, and ii) additional specimens identified as Hesperinus sp. by Messias Carrera in 1944. In this study, we revisited the Carrera’s specimens, identifying them as Plecia sp. Additionally, we discussed the taxonomy of Plecia conjungens and compiled a list of articles that consider the species as Hesperinus.

The study of relationships between living beings is essential for understanding the functioning of the ecosystem for the management and conservation of biota, especially in rich and threatened biomes such as the Brazilian Cerrado. Therefore, this study aims to report the occupation of abandoned social wasp’s nests by termites in this biome. In this study, the occupation of two abandoned nests of Synoeca surinama (L.) by the termite Nasutitermes obscurus (Holmgren), recorded by chance, in April 2023 in a gallery forest with the same vegetation type of the Cerrado, located in the Grande Sertão Veredas National Park in southeastern Brazil. Both social wasp nests had their cells occupied by termites, which may have been used as a satellite nest for N. obscurus. This is the first record of a termite species occupying a social wasp’s nests; however, further studies are needed to better elucidate this relationship.
研究生物之间的关系对于了解生态系统的功能、管理和保护生物群落至关重要，尤其是在巴西塞拉多这样富饶而又濒临灭绝的生物群落中。因此，本研究旨在报告白蚁占据该生物群落中被遗弃的社会蜂巢的情况。在这项研究中，白蚁 Nasutitermes obscurus (Holmgren) 于 2023 年 4 月在巴西东南部 Grande Sertão Veredas 国家公园内具有相同塞拉多植被类型的廊道森林中偶然发现了两个被遗弃的社会黄蜂巢。这两个社会蜂巢的巢穴都被白蚁占据，白蚁可能将其用作 N. obscurus 的卫星巢。这是白蚁物种占据社会黄蜂巢穴的首次记录；然而，要更好地阐明这种关系，还需要进一步的研究。

Two new species of the small carpenter bee genus Ceratina (Calloceratina) Cockerell, 1924 are described and illustrated. Ceratina (Calloceratina) mourei new species, and Ceratina (Calloceratina) silveirai new species, form the silveirai species-group, a very distinct set within the subgenus C. (Calloceratina). The taxonomy of South American species was approached, being redescribed and illustrated the species Ceratina (Calloceratina) chloris (Fabricius, 1804) and Ceratina (Calloceratina) triangulifera Cockerell, 1914, proposing the chloris species-group for them. The diagnosis for the subgenus Calloceratina is presented and an identification key for the South American species is also proposed.

This work reports the first photographic record of the Symmachia basilissa basilissa Bates, 1868 subspecies, a butterfly originally described by Henry Walter Bates in 1868. This subspecies had only been recorded three before but had never been photographed alive in Brazil. The photograph was taken in the Chapada das Mesas National Park, located in the southern part of the state of Maranhão. This record was uploaded and georeferenced on the iNaturalist app/website. The taxon Symmachia basilissa comprises four subspecies, and the article provides information on the morphological differences between them. We also discuss the use of iNaturalist and similar tools to integrate academic and citizen science for a better understanding of biodiversity, especially in tropical regions and areas that are difficult to access. Overall, our work makes a valuable contribution to the knowledge of this data deficient butterfly species and highlights the importance of utilizing new technologies and collaborative approaches to advance scientific research.
本作品首次记录了1868年亚种Symmachia basilissa basilissa Bates的照片，该蝴蝶最初由Henry Walter Bates于1868年描述。这个亚种之前只被记录过3次，但从未在巴西被拍到过。这张照片是在位于马兰赫奥州南部的恰帕达斯梅萨斯国家公园拍摄的。该记录被上传并在iNaturalist应用程序/网站上进行地理参考。该分类群包括4个亚种，本文介绍了不同亚种间的形态差异。我们还讨论了使用iNaturalist和类似的工具来整合学术和公民科学，以更好地了解生物多样性，特别是在热带地区和难以进入的地区。总的来说，我们的工作为了解这种缺乏数据的蝴蝶物种做出了宝贵的贡献，并突出了利用新技术和合作方法推进科学研究的重要性。

The photograph was taken in the Chapada das Mesas National Park, located in the southern part of the state of Maranhão. This record was uploaded and georeferenced on the iNaturalist app/website. The taxon Symmachia basilissa comprises four subspecies, and the article provides information on the morphological differences between them. We also discuss the use of iNaturalist and similar tools to integrate academic and citizen science for a better understanding of biodiversity, especially in tropical regions and areas that are difficult to access. Overall, our work makes a valuable contribution to the knowledge of this data deficient butterfly species and highlights the importance of utilizing new technologies and collaborative approaches to advance scientific research.","PeriodicalId":11746,"journal":{"name":"EntomoBrasilis","volume":"18 2","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135221183","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Psychoda Latreille is one of the largest genera of Psychodidae, with around 450 species, from which more than 130 are known from only one of the sexes. This is a result of the high diversity, sympatry of close related species and scarcity of diagnostic characters to accurately associate males and females in this genus. Here we describe a new species, Psychoda dactyla sp. n., from Brazil, Amazonas, São Gabriel da Cachoeira with morphological description of male and female specimens associated by DNA-barcoding.
Latreille精神病是精神病科最大的属之一，大约有450种，其中130多种仅属于一种性别。这是由于高多样性、近缘种的同属性和缺乏准确区分雌雄的诊断性状的结果。本文描述了来自巴西亚马逊地区 o Gabriel da Cachoeira的一新种——dactyla Psychoda sp. n.，并通过dna条形码对其雌雄标本进行了形态学描述。
