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, <em>Lestrimelitta chacoana</em> 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.</p>2024-05-21T00:00:00-03:00Copyright (c) 2024 Author(s)https://www.entomobrasilis.org/index.php/ebras/article/view/e1082Record of Lepidoptera and Hemiptera as a food resource of Acutisoma longipes Roewer, 1913 (Arachnida; Opiliones) in the Cerrado, Brazil2024-05-27T17:37:51-03:00Maria Luiza Simões Silvamaria19.silva@alunos.ifsuldeminas.edu.brIgor Rodrigues de Castrocastro.igor25@gmail.comFelipe Barbosa Augusto de Freitasfelipe.freitas@alunos.ifsuldeminas.edu.brDiogo Silva Vileladiogo.vilela@ifsuldeminas.edu.brGabriel de Castro Jacquesgabriel.jacques@ifmg.edu.brMarcos Magalhães de Souzamarcos.souza@ifsuldeminas.edu.br<p>Harvestmen are nocturnal arachnids, commonly found in humid forests, with omnivorous feeding behavior. There are records of different taxa in the diet of these arthropods, but data is still scarce for many species, especially in Cerrado areas. Thus, the objective of the present work is to report Lepidoptera and Hemiptera in the diet of the harvestman <em>Acutisoma longipes</em> Roewer, 1913, in Mata de Galeria in the Cerrado of Minas Gerais, Brazil. The records occurred randomly in the municipality of Luminárias, Minas Gerais, on October 10th and December 4th, 2023. In the first record, the species A. longipes was feeding on a moth (Lepidoptera: Erebidae). In the second record, the same species fed on a leafhopper, <em>Mahanarva</em> sp. (Hemiptera, Cercopidae). It was not possible to say whether these insects were preyed upon, usurped by other predators or found dead, but any of these hypotheses can be considered. This record contributes to increasing knowledge about the diet of harvestmen, especially in the Cerrado biome, where there is a need for more related studies.</p>2024-06-21T00:00:00-03:00Copyright (c) 2024 Author(s)https://www.entomobrasilis.org/index.php/ebras/article/view/e1081Harmonia axyridis (Pallas, 1773) (Coleoptera: Coccinellidae) as a predator of the leaf-galling form of the grape phylloxera Daktulosphaira vitifoliae (Fitch, 1856) (Hemiptera: Phylloxeridae) in Brazil2024-05-21T09:34:36-03:00Daiana da Costa Oliveiradaiana_oliveirabio@hotmail.comSimone Andzeiewskisimoneandzeiewski@yahoo.com.brRégis Josué Bohnrjosuweb@gmail.comLuciano de Azevedo Mouraluciano-moura@sema.rs.gov.brDaniel Bernardidbernardi2004@yahoo.com.brMarcos Bottonmarcos.botton@embrapa.br<p><em>Harmonia axyridis</em> (Pallas, 1773) (Coleoptera: Coccinellidae) is an Asian species intentionally introduced in many countries as a biological control agent for insect pests.

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 <em>E. e. erysice</em>. 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.</p>2024-04-16T00:00:00-03:00Copyright (c) 2024 Author(s)https://www.entomobrasilis.org/index.php/ebras/article/view/e1079Antennal ultrastructure of three species of Cyclocephala Dejean, 1821 (Coleoptera: Scarabaeidae)2024-03-07T20:04:30-03:00Sérgio Roberto Rodriguessergio@uems.brAndrezza Santos Coccoandrezzacoc@gmail.com<p>This study describes the antennal ultrastructure in <em>Cyclocephala forsteri</em> Endrodi, 1963, <em>Cyclocephala melanocephala</em> (Fabricius, 1775) and <em>Cyclocephala tucumana</em> Brethes, 1904 (Coleoptera: Scarabaeidae). Adult of <em>Cyclocephala</em> Dejean, 1821 specimens were collected using a light trap placed near a pasture area, segregated by gender, based on male-specific dilated pre-tarsomeres and preserved in 70% alcohol. Scanning electron microscopy (SEM) images of the antenna lamellae were obtained from ten specimens at Universidade Estadual Paulista (UNESP) in Ilha Solteira, SP, Brazil. We identified trichoid, chaetic, placoid, coeloconic, basiconic sensilla, and pores in antenna of all the species. Placoid sensilla were prevalent in the antennal lamellae. The antennae of <em>C. forsteri</em> females had 5,457 sensilla, of which 5,327 (97.62%) were placoid, 123 (2.25%) coeloconic, and seven (0.13%) basiconic, while the antennae of males showed 5,351 sensilla, with 5,238 (97.89%) being placoid, 100 (1.87%) coeloconic, and 13 (0.24%) basiconic. The antennae of <em>C. melanocephala</em> females presented 6,814 sensilla, with 6,581 (96.58%) being placoid, 231 (3.39%) coeloconic, and two (0.03%) basiconic; while those of males had 6,333 sensilla, with 6,023 (95.11%) being placoid and 310 (4.89%) coeloconic. Finally, the antennae of C. tucumana females had 1,981 sensilla, with 1,845 (93.13%) being placoid, 127 (6.42%) coeloconic, and nine (0.45%) basiconic; while the antennae of males had 3,756 sensilla, with 3,656 (97.34%) being placoid, 99 (2.64%) coeloconic, and one (0.02%) basiconic.

In this report we describe a case of multiple colonization of a preserved male cadaver found indoors in Santa Catarina State, southern Brazil, by four dipterans species of four different families:<em> Fannia canicularis</em> (Linnaeus, 1761) (Diptera: Fanniidae),<em> Microcerella halli</em> (Engel, 1931) (Diptera: Sarcophagidae), <em>Muscina stabulans</em> (Fallén, 1817) (Diptera: Muscidae) and <em>Sarconesia chlorogaster</em> (Wiedemann, 1830) (Diptera: Calliphoridae). The development time data of the species were used to estimate the minimum postmortem interval (PMI). Considering the methodology applied in this study and the values calculated for the species development, it was possible to estimate a minimum PMI of 24 days. Besides the diversity of dipteran species colonizing a single human body in an indoor environment, this case report reinforces the importance of these species as forensically indicator to estimate the time of death.</p>2024-06-11T00:00:00-03:00Copyright (c) 2024 Author(s)https://www.entomobrasilis.org/index.php/ebras/article/view/e1076Idiopidae Simon, 1889 in the Brazilian Amazon: two new species and a new geographic record2024-04-01T11:59:57-03:00João Pedro Costa Gomespedrogomes.bio@gmail.comNaila Amanda Sousa dos Santosnailaamanda.s.santos@gmail.comMarlus Queiroz Almeidamarlus.almeida@mtaboca.com.brNikolas Gioia Cipolanikolasgc@gmail.comJosé Wellington de Moraismoraisjw@gmail.com<p>Idiopidae Simon, 1889 is mostly composed of spiders known as trapdoor spiders, which create structures for shelter, hunting and protection against possible predators (Mason et al., 2013).

The proposal of this study is to test the efficiency of a new trap model in capturing and trapping <em>Ae. aegypti</em> 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 <em>Ae. aegypti</em> 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 <em>Ae. aegypti</em> 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 <em>Ae. aegypti</em> in urban areas.</p>2024-05-09T00:00:00-03:00Copyright (c) 2024 Author(s)https://www.entomobrasilis.org/index.php/ebras/article/view/e1071When the predator becomes the prey: record of Mischocyttarus rotundicollis (Cameron, 1912) (Hymenoptera: Vespidae) feeding on a spider in southeastern Brazil2024-03-27T18:20:13-03:00Glauco Cássio de Sousa Oliveiraglaucomlds@hotmail.comIgor Henrique da Silvaigor2.silva@alunos.ifsuldeminas.edu.brDiogo Silva Vileladiogo.vilela@ifsuldeminas.edu.brMarcos Magalhães de Souzamarcos.souza@ifsuldeminas.edu.br<p>Social wasps are commonly considered generalists in their feeding habits, but there are genera with little information regarding their diet, such as <em>Mischocyttarus</em> de Saussure, 1853 (Hymenoptera: Vespidae), the most species-rich wasp genus in the world. The objective of this study is to report <em>Mischocyttarus rotundicollis</em> (Cameron, 1912) (Hymenoptera: Vespidae) feeding on a spider in the southeastern region of Brazil, aiming to expand information about its feeding behavior. The record occurred occasionally on September 23, 2023, in the state of Minas Gerais, Brazil, in the ecotone region between the Atlantic Forest and the Cerrado. The feeding of a species from the Araneidae family occurred in its web, and the individual of <em>M. rotundicollis</em> used the tarsi of its legs to cling to the silk threads of the web, which could suggest a specialization for the exploitation of this food resource. Our record provides further information on the feeding behavior and diet of <em>M. rotundicollis</em> and presents the first information on spider feeding by this species. Further studies are suggested to evaluate this possible hypothesis of specialization of the genus for foraging in spider webs.</p>2024-04-26T00:00:00-03:00Copyright (c) 2024 Author(s)
