A new species of Horismenus Walker, H. saturnus Schoeninger & Hansson (Hymenoptera: Eulophidae), is described from material reared from eggs of an unidentified species of Saturniidae (Lepidoptera). The new species is compared to H. cupreus (Ashmead, 1894), a species it is very similar to, and to H. ancillus (Brèthes), a species with the same type of host as H. saturnus. A total of 30 adult specimens developed from the eggs of Saturniidae. This is the second record of a Horismenus species parasitizing eggs of Saturniidae and the first record of this host from Brazil. Here, we provide a diagnosis and description of the new species including morphological and molecular characters, and multiple illustrations.

Common bean (Phaseolus vulgaris L.) is the most important legume used for direct human consumption in Latin America, with an increasing expansion of cultivated areas in recent years. Here, we report the first occurrence of Conotrachelus quadrilineatus Champion, 1904 (Coleoptera: Curculionidae: Molytinae) feeding on bean in South America. Larvae and adults of C. quadrilineatus were observed during the first half of 2022, severely affecting the plantations of 20 bean farmers in the municipality of Garcia-Rovira, Santander Colombia. It is necessary to describe and quantify the damage of C. quadrilineatus in bean crops, as well as to study its bioecology.

During an ongoing project aiming to understand the dynamics of Ephemeroptera biodiversity in the Doce River Basin after the disaster, an unusual large number of Apobaetis Day, 1955 were analyzed. The occurrence of Apobaetis is quite relevant, since the combination of factors such as its small body size and its habitat preferences makes their collection difficult and its presence often neglected. For the first time in science, adults of Apobaetis irai De Lima, Massariol, Cruz & Hamada, 2022 and Apobaetis fiuzai Salles & Lugo-Ortiz, 2002 are described and diagnosed. Apobaetis irai can be easily distinguished, among other characteristics by turbinate portion of compound eyes touching each other along midline; abdominal terga II-III and V-VII with well-marked lines on lateral and posterior margins; posterior margin of subgenital plate with projection broadly rounded to slightly truncate. Apobaetis fiuzai are diagnosed by turbinate portion of compound eyes touching each other posteriorly; mesothorax brown, except for broad cream marks on anterior margin of PSp and SLS, SSLi tinged with white, posterior corner of SMS with a red spot; abdominal terga II-VI translucent orangish-brown, terga VII-X brown, terga II-III and VI with conspicuous red medial mark; posterior margin of subgenital plate with subtriangular projection, apex narrowly truncate; forceps base wider at base, inner irregular edges. The new records of A. irai and A. fiuzai extend the distribution of Apobaetis within Minas Gerais and Espírito Santo States, Brazil. Furthermore, it is reported for the first time cases of gynandromorphs for Apobaetis.
目前正在进行的一个项目旨在了解多塞河流域灾后蜉蝣类生物多样性的动态,在该项目中,对 1955 年出现的大量 Apobaetis Day 进行了分析。Apobaetis的出现具有相当重要的意义,因为其体型小和对栖息地的偏好等综合因素使其难以采集,其存在往往被忽视。科学界首次描述并诊断了Apobaetis irai De Lima, Massariol, Cruz & Hamada, 2022年和Apobaetis fiuzai Salles & Lugo-Ortiz, 2002年的成虫。除其他特征外,Apobaetis irai 很容易区分,复眼的甲状突起部分沿中线相互接触;腹部第 II-III 和第 V-VII 背片的侧缘和后缘有清晰的标记线;亚生殖板后缘的突起呈宽圆形或稍截形。Apobaetis fiuzai 的诊断方法是复眼的甲状突起部分在后方相互接触;中胸褐色,但 PSp 和 SLS 的前缘有宽的奶油色痕迹,SSLi 染有白色,SMS 的后角有红色斑点;腹部第 II-VI 背片半透明橙褐色,第 VII-X 背片褐色,第 II-III 背片和第 VI 背片中间有明显的红色斑纹;亚属板后缘有近三角形突起,先端狭截形;镊子基部较宽,内部边缘不规则。新记录的 A. irai 和 A. fiuzai 扩大了 Apobaetis 在巴西米纳斯吉拉斯州和圣埃斯皮里图州的分布范围。此外,这是首次报道雌雄同体的 Apobaetis。

This study investigates the toxic effects of the insecticide spinetoram on the model organism Bombyx mori (Linnaeus) and explores the potential ameliorative properties of O-Vanillin. Sub-lethal concentrations of spinetoram were given to silkworm larvae via oral feed, resulting in reduced body weight, larval length, and impaired cocoon characteristics. A study of the enzymatic and non-enzymatic antioxidants revealed oxidative stress in the gut, fat body, and silk gland tissues, characterized by decreased antioxidants and increased lipid peroxidation. However, post-treatment with O-Vanillin effectively mitigated these toxic effects, preserving antioxidant capacities and preventing lipid peroxidation. Additionally, O-Vanillin prevented the loss of body weight and improved cocoon characteristics. At the histological level, spinetoram exposure caused mild histological damage in the gut, fat body, and silk gland. However, O-Vanillin post-treatment had ameliorative effects and mitigated the histological damages. To delve deeper into the mechanism of amelioration of O-Vanillin, in silico studies were used to study the interaction between an important xenobiotic metabolism protein of the Bombyx mori, i.e., Cytochrome p450, specifically CYP9A19, and O-Vanillin. We performed blind molecular docking followed by molecular dynamic simulation, and the results demonstrated stable binding interactions between O-Vanillin and CYP9A19, a cytochrome P450 protein in silkworm, belonging to the subfamily CYP9A, suggesting a potential role for O-vanillin in modulating xenobiotic metabolism.

There are few records for Telenomus dilophonotae Cameron, 1913 (Hymenoptera, Scelionidae) from South America. In Brazil, the first occurrence was reported in Bahia in rubber crops, Hevea brasiliensis (Willd. ex Adr. de Juss.) Muell. - Arg., there parasitizing eggs of Erinnyis ello Linnaeus, 1758 (Lepidoptera, Sphingidae). It was also found parasitizing the same host in cassava, Manihot esculenta Crantz (Euphorbiaceae). This is the first record of occurrence of T. dilophonotae in the state of Paraná, parasitizing eggs of E. ello in areas of cassava production in the western region of Paraná, this being the southernmost record of the species. Here, photographs, the first sequence of DNA barcode of this species of parasitoid wasp, and a distribution map are provided.

The study aimed to understand the feeding behavior of Neotropical brown stink bug nymphs Euschistus heros (F.) on soybean plants during vegetative stage through electropenetrography (EPG) technique. Three distinct phases were identified: non-feeding, pathway, and ingestion. Waveforms representing these phases were consistent across nymphal instars and plant structures, and named Np, Eh1, and Eh2, respectively. Biological interpretations of the waveforms were proposed by integrating visual observations, comparisons with adult waveforms, and histological studies. The waveforms Np, Eh1, and Eh2 were associated with resting/walking, initial stylet-plant contact, and xylem sap ingestion, respectively. Notably, nymphs showed a higher number of Eh1 events and longer durations when feeding on petioles compared to leaves, particularly in younger instars. However, differences between instars diminished in older nymphs. Fifth instars consistently exhibited the highest Eh1 values, and displayed longer xylem ingestion durations compared to other instars. Second instars demonstrated increased xylem ingestion events on petioles compared to leaves. Across plant structures, on petioles, nymphs generally showed longer xylem ingestion durations than on leaf surfaces. Fifth instar consistently had the longest ingestion durations overall. Additionally, statistical differences in xylem ingestion duration were observed between instars within each plant structure, with fifth instars displaying the longest durations. These findings offer valuable insights into the feeding behavior of E. heros nymphs, which could inform the development of more effective pest management strategies for soybean crops.

Coffee berry borer (CBB) Hypothenemus hampei is a major biotic threat to coffee production worldwide. Studies have reported negative effects on CBB by oil-based formulations of neem (Azadirachta indica), but little information is available for other neem-extract formulations. This study evaluated CBB preference and performance in arabica coffee fruits and artificial diet treated with a neem-extract formulation (Openeem Plus®) in the field and laboratory conditions. Field experiments were performed using CBB females artificially infested in cherry or green coffee fruits confined in voile-fabric cages tied to branches of neem-treated and control plants, recording the adult mortality and offspring production. Dual-choice and no-choice bioassays assessed CBB preference and development in fruits and artificial diet treated with the neem extract compared to controls in the laboratory, respectively. As main results obtained in the field and laboratory experiments, the neem extract significantly reduced CBB oviposition in both cherry and green fruits, as well as in artificial diet compared to controls. However, the botanical product did not affect CBB adult survival and preference in the laboratory bioassays. The neem extract is promising for use in pest management strategies in sustainable arabica coffee crops by reducing CBB oviposition and offspring. These effects can contribute to lowering the pest population buildup along the crop cycle and damage potential to coffee production.

Studies have reported negative effects on CBB by oil-based formulations of neem (Azadirachta indica), but little information is available for other neem-extract formulations. This study evaluated CBB preference and performance in arabica coffee fruits and artificial diet treated with a neem-extract formulation (Openeem Plus®) in the field and laboratory conditions. Field experiments were performed using CBB females artificially infested in cherry or green coffee fruits confined in voile-fabric cages tied to branches of neem-treated and control plants, recording the adult mortality and offspring production. Dual-choice and no-choice bioassays assessed CBB preference and development in fruits and artificial diet treated with the neem extract compared to controls in the laboratory, respectively. As main results obtained in the field and laboratory experiments, the neem extract significantly reduced CBB oviposition in both cherry and green fruits, as well as in artificial diet compared to controls. However, the botanical product did not affect CBB adult survival and preference in the laboratory bioassays. The neem extract is promising for use in pest management strategies in sustainable arabica coffee crops by reducing CBB oviposition and offspring. These effects can contribute to lowering the pest population buildup along the crop cycle and damage potential to coffee production.</p>","PeriodicalId":19071,"journal":{"name":"Neotropical Entomology","volume":" ","pages":"1149-1157"},"PeriodicalIF":1.4,"publicationDate":"2024-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141976194","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}
