The species of the cleptobiotic bee genus Lestrimelitta Friese, 1903 (Hymenoptera: Apidae) are generally known as a menace to Meliponiculture and Apiculture, that is why it is common to observe recommendations to beekeepers to avoid the proximity of their meliponaries with any Lestrimelitta hives. So, besides other anthropic pressures, the growth of beekeeping may represent a particular threat to its species. In this note we address the distribution of three species recorded in the triple border region of Argentina, Paraguay, and Brazil. One of these species, Lestrimelitta chacoana Roig-Alsina, 2010 (Hymenoptera: Apidae), previously described from the Argentinian Dry Chaco, is recorded for the Semideciduous Atlantic Forest in Southern Brazil where it was already expected to be found due to its previous record in a contiguous forest type in Northeastern Argentina. A discussion about the characters to differentiate it from two other species is made.

The species Aedes (Stegomyia) aegypti (Linnaeus, 1762) (Diptera: Culicidae) is of great importance for human health, as it is responsible for the transmission of viruses that can cause dengue, chikungunya, zika and urban yellow fever. The proposal of this study is to test the efficiency of a new trap model in capturing and trapping Ae. aegypti based on favoring the insect's ecology. This trap model was analyzed regarding the attractiveness for egg-laying, and the trapping of larvae and consequently the adults. The tests were carried out using white traps (original version) and black traps (adapted from the original), both in field and laboratory conditions. In the field, the black traps showed 100% effectiveness compared to white traps, showing more positive results for the attractiveness of Ae. aegypti mosquito and adult imprisonment. According to the results for this trap model, from both test in the field and in the laboratory, it was concluded that this new product is effective in capturing Ae. aegypti and it guarantees mosquito trapping safety, also low-cost production, practicality, logistics and possibility of its use by the local population. After the validation and effectiveness of the trap “drinking-fountain like”, the definitive trap called Mosquitex was developed, which is brand new for this mosquito, with patent registration INPI - BR2020190112226 - 2019, and with the possibility of assisting in the control and monitoring of Ae. aegypti in urban areas.

The Brazilian endemic butterfly Eresia erysice erysice (Geyer, 1832) (Lepidoptera: Nymphalidae) has been included in the Official List of Brazilian Endangered Fauna as critically endangered (CR). Until now, this rare butterfly has only been known to inhabit Atlantic Forest fragments in the “Hileia Baiana”. This paper presents updated information on occurrences of E. e. erysice. A male and a female specimens were collected in a disturbed forest fragment near the experimental fields of the Centro de Pesquisas do Cacau (CEPEC), Ilhéus, Bahia. These new findings indicate that the distribution boundary of this subspecies extends about 80 km more to the north and suggest that it is not as exclusive to forest habitats as previously thought.
巴西特有蝴蝶 Eresia erysice erysice(Geyer,1832 年)(鳞翅目:蛱蝶科)已被列入巴西濒危动物官方名录,列为极度濒危物种(CR)。到目前为止,人们只知道这种稀有蝴蝶栖息在 "Hileia Baiana "的大西洋森林片区。本文介绍了 E. e. erysice 的最新分布信息。在巴伊亚州伊尔赫斯市卡考研究中心(Centro de Pesquisas do Cacau,CEPEC)实验田附近的一片受干扰的森林片段中采集到了一只雄性和一只雌性标本。这些新发现表明,该亚种的分布边界向北延伸了约80公里,并表明该亚种并不像之前认为的那样专属于森林栖息地。

The present study aimed to evaluate, qualitatively and quantitatively, yellow sticky traps and entomological net in the monitoring of Monellia caryella (Fitch, 1855) (Hemiptera: Aphididae) and its predators in a pecan plantation in Santa Maria, Rio Grande do Sul, Brazil. This plantation was implemented on 1.2 ha in February 2012 with the Barton and Shawnee varieties at a spacing of 7 m x 7 m. Twenty pecan plants were randomly selected to sample the blackmargined pecan aphid and its predators. From November 2014 to May 2015, 13 collections were carried out with yellow sticky traps and an entomological net. A total of 898 arthropod specimens were collected, 50.9% of which were from yellow sticky traps and 49.1% from the entomological net trap. Regarding the yellow sticky traps, only M. caryella was identified at the species level, with the predators identified at the taxonomic levels of order (Araneae) and family (Coccinellidae; Coleoptera). In terms of the entomological net, all the insects of interest at the species level were identified. There was a significant difference only between the averages in the number of Araneae specimens, with the highest density found in the yellow sticky traps. Both methods provided the correct identification of M. caryella and efficiently recorded its population peak. It is concluded that yellow sticky traps are effective for monitoring M. caryella, while the entomological net is suitable for monitoring and correctly identifying species of natural enemies of the insect pest in pecan plantations.

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。

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。

Chrysotus capellarii Soares & Carvalho-Filho sp. nov. is described and illustrated based on a single specimen collected in the department of Córdoba, Colombia, representing the first record of the longipalpus species group from the country (a photographic record is known from Costa Rica). The new species is easily recognized by the long palpus (about 2x longer than eye height) with a wide and oval apical lamella.
