Galls are small structures induced mostly by insects in different plant organs, and have different shapes and colorations. Knowledge on galls is still sparse in the semiarid region of Bahia. Therefore, the goal of this study was to characterize galls in fragments of seasonal deciduous forest. Sampling was performed in the Bahia municipalities of Boa Nova, Jequié, Poções and Vitória da Conquista. In each site, one fragment was chosen, and in each fragment, plots were established to survey galls on vegetation. We sampled 158 gall morphotypes, representing 49 (morpho) species distributed across 15 families of host plants. Myrtaceae and Malphigiaceae had the highest numbers of gall morphotypes. Most galls were collected from leaves, whereas the most common gall morphotypes were globoid and fusiform.
瘿是昆虫在植物不同器官中诱导形成的小结构，具有不同的形状和颜色。在巴伊亚的半干旱地区，关于虫瘿的知识仍然很少。因此，本研究的目的是在季节性落叶林中的碎片中表征瘿瘤。在巴伊亚州的博阿诺娃、杰奎、Poções和Vitória da Conquista市进行了抽样。在每个样点选取一个样点，在每个样点建立样点，对植被上的瘿瘤进行调查。我们采集了158种瘿虫形态，代表了分布于寄主植物15科的49种(形态)。桃金娘科和麻瓜科的瘿型数量最多。大部分瘿来自叶片，而最常见的瘿形态是球形和梭形。

Odonata sampling effort in the state of Minas Gerais has intensified throughout the 21st century. However, research on these insects in some regions and ecosystems such as the Deciduous Forest are incipient, and the effect of prolonged dry periods over these insects is still unknown. This study thus aimed to assess changes in adult Odonata species composition over one year in a Brazilian Deciduous Forest and the Odonata species richness in the Mata Seca State Park in the Manga and Itacarambi municipalities in the Northern region of the state of Minas Gerais State, Brazil. Twenty-four days of sampling were distributed in February, May, July and November, adopting an active search through entomological nets close to lentic environments (Lagoa Angical, Lagoa Comprida, Lagoa Encantada, Lagoa da Prata and two wetlands of Lajedo da Lua); lotic environments (São Francisco river) and in associated terrestrial ecosystems. In total, 55 species were collected. Rainy and dry periods altered Odonata communities’ composition but did not affect species richness and abundance due to the presence of permanent lagoons associated with the São Francisco river. This study shows the importance of the Mata Seca State Park for preserving Odonatofauna in the state of Minas Gerais and for protecting those permanent lagoons.
在整个21世纪，米纳斯吉拉斯州的奥多纳塔取样工作得到了加强。然而，在一些地区和生态系统，如落叶林区，对这些昆虫的研究尚处于起步阶段，长期干旱对这些昆虫的影响尚不清楚。因此，本研究旨在评估巴西落叶林中成虫物种组成在一年内的变化，以及巴西米纳斯吉拉斯州北部地区Manga和Itacarambi市Mata Seca州立公园内的虫类物种丰富度。采样时间为2月、5月、7月和11月，采样时间为24天，采用靠近真实环境(Lagoa Angical、Lagoa Comprida、Lagoa Encantada、Lagoa da Prata和Lajedo da Lua两个湿地)的昆虫网进行主动搜索;河流环境(弗朗西斯科河)和相关的陆地生态系统。共采集到55种。由于 o Francisco河附近存在永久性泻湖，因此雨季和干旱期改变了蛇目动物群落的组成，但没有影响物种的丰富度和丰度。这项研究显示了马塔塞卡州立公园对保护米纳斯吉拉斯州的巨齿兽和保护那些永久泻湖的重要性。

Lepidoptera is a diverse and abundant group of insects, widely used in biodiversity and conservation studies, as it has great social appeal. From this perspective, this study was aimed to conduct a survey of flower – visiting butterfly species in Bosque da Ciência, at the Instituto Nacional de Pesquisas da Amazônia (INPA), an urban forest fragment open to public visitation in the State of Amazonas, Brazil. Thus, attractive plants for nectarivorous butterflies were observed, and the best location and conditions for viewing such diversity, as well as a guide for their identification was proposed. Forty-three species of flower – visiting butterflies were identified, among which Anthoptus epictetus (Fabricius), Ascia monuste (Linnaeus), Anartia jatrophae (Linnaeus), Eurema albula (Cramer) were observed to be more frequent. According to the species accumulation curve, the species richness of butterflies would be higher if greater collection effort were employed. The period of greatest flight activity and flower - visitation occurred from 9 am to 11 am. Of the six attractive plants identified, Stachytarpheta cayennensis (Rich.) and Lantana camara L. were the most visited, so we consider that these species are important for butterfly attractiveness. The butterflies of Bosque da Ciência are a representation of the nectarivores guild of the city of Manaus, Amazonas, and the establishment of an attractive butterfly garden in this place can contribute to the promotion of environmental education by stimulating the knowledge and awareness for biodiversity preservation.

The puruí Alibertia edulis (Rich.) A. Rich. (Rubiaceae) is a naturally occurring species in the Cerrado biome in Brazil; its fruits serve as food for the local fauna (birds and mammals) and humans. Here, we report on a beetle feeding on the fruits of A. edulis in the Cerrado of Minas Gerais (MG). Monthly collections were carried out in four A. edulis trees in two areas of Cerradão in the vicinity of the municipality of Monte Carmelo, MG, between September and October 2018. These were a legal reserve area of Fazenda Juliana (ARL; Juliana Farm; 18°42'30 "S and 47°33'05 "W) and an area at the Atalho Community (ACA; 18°41'39 "S and 47°34'49 "W). Fruits with or without attack symptoms were collected from the treetop in the four cardinal directions. A total of 100 fruits (50 from each area) were collected from the trees and packed into plastic bags. The fruits were then transported to the laboratory, stored in plastic containers isolated with voile fabric, and checked daily for the emergence of adult insects. After emergence, the insects were identified. During the evaluation period, 33 beetles emerged in puruí fruits from ARL and 13 from ACA. The species has been identified as Eubulus (Kirsch) sp. (Coleoptera: Curculionidae). The animals consumed the entire fruit endocarp, leaving it with emergence orifices caused by the adult emergence. It is concluded that Eubulus sp. feeds on the pulp of A. edulis and is able to compete for this resource with other animal species.

Ethylene is a volatile phytohormone that plays an important role in the physiological processes of coffee plants. However, the role of this compound as a semiochemical in the tritrophic interaction involving Hypothenemus hampei, Coffea canephora, and hymenopteran insects remains unknown. Ethylene-baited traps were used in a coffee plantation in the experimental field of Embrapa Rondônia in the municipality of Porto Velho, Rondônia state, Brazil. The experiment was conducted during the fruit maturation period (March and April). Ethylene did not attract H. hampei compared to control traps (distilled water) but was significantly attractive to hymenopterans suggesting that it acts as a synomone.

Various host compounds have been investigated to produce an alternative attractant for monitoring and controlling pest insects. Several studies evidenced that volatile molecules released by coffee and mangoes attracted both male and female Ceratitis capitata (Wiedemann), a significant pest in fruit crops. In this study, we tested the effectiveness of the commercial glycolic extract of coffee (Coffea arabica L.) and a commercial mango essence (Mangifera indica L.) to attract C. capitata. We identified the main volatile compounds (VOCs) emitted from such products. The experiments were conducted in field cages and showed that the glycolic extract of coffee attracts both sexes of C. capitata, while the mango essence attracts only males. After seven days, the pH of the coffee extract and mango essence did not change. These results indicate that attractants based on commercial fruit extracts and essences can be an option for integrated pest management of the Mediterranean fruit fly in orchards.

Cassava crops hold high agricultural importance in Paraná State, Brazil. However, cassava root production is adversely impacted by pests. Aleyrodids, in particular, cause great damage to cassava fields, necessitating better knowledge of predators found in these agroecosystems and novel biological control strategies for integrated pest management. This study reports the first occurrence of the predatory lady beetle Delphastus argentinicus Nunenmacher, preying on all life stages of whiteflies in cassava fields. Given the economic and social importance of cassava crops in Brazil and the deleterious potential of aleyrodid species, it is recommended to conduct behavioral and bioecological studies assessing the application of D. argentinicus as a biocontrol agent in integrated pest management programs.

Recently, Martins-Silva (2022) published the article entitled “Checklist of Aquatic Heteroptera genera (Insecta: Hemiptera) from Brazilian Savanna (Cerrado Biome), with family and genera identification key”. The paper provides information on which genera of aquatic Heteroptera would occur in the Cerrado biome and an identification key to families and genera, based on specimens deposited in the Aquatic Invertebrates Collection of the University of Brasília, Brazil. However, it presents many problems, including misidentifications, lack of care with references, scientific names and taxonomic authorities, and poor grammar, syntax and spelling. Here, we express our concern about this paper and provide identification corrections for specimens figured in it whenever possible.

Here, we express our concern about this paper and provide identification corrections for specimens figured in it whenever possible.","PeriodicalId":11746,"journal":{"name":"EntomoBrasilis","volume":"8 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-10-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76989010","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}
