Metarhizium anisopliae (Ascomycota: Hypocreales) is an entomopathogenic fungus considered a key factor in developing integrated management of several insect pests on a variety of crops. The predatory coccinellid, Menochilus sexmaculatus (Col.: Coccinellidae), is also an important natural enemy that must be conserved for effective aphid control. Laboratory studies were conducted under controlled conditions to investigate the interaction between M. anisopliae isolate IRN. 1 and the coccinellid predator M. sexmaculatus in combating Aphis gossypii Glover (Hem.: Aphididae). The combined application of M. sexmaculatus and M. anisopliae led to significant reduction in aphid populations. The foraging behavior of M. sexmaculatus notably facilitated the dispersion of M. anisopliae conidia to uninfected plants, resulting 54 ± 1.3% decrease in aphid density after 10 days. In both choice and non-choice experiments, female adult M. sexmaculatus to fungus-infected aphids was offered as prey and avoided as a food source during all starvation periods. However, live and dead non-fungus-infected aphids were fed upon. The result revealed the compatibility between M. sexmaculatus and M. anisopliae, which may provide a sustainable strategy for the effective management of A. gossypii in a cropping system.

Metarhizium anisopliae(子囊菌目:Hypocreales)是一种昆虫病原真菌,被认为是对多种作物上的几种害虫进行综合防治的关键因素。捕食性茧丝蝇(Menochilus sexmaculatus,Col.: Coccinellidae)也是一种重要的天敌,必须加以保护才能有效控制蚜虫。在受控条件下进行了实验室研究,以调查 M. anisopliae 分离物 IRN.1 与茧蜂天敌 M. sexmaculatus 在防治棉蚜(Aphis gossypii Glover)(Hem.联合施用蚜茧蜂和蚜茧蜂可显著减少蚜虫数量。M.sexmaculatus的觅食行为明显促进了M. anisopliae分生孢子向未感染植物的扩散,10天后蚜虫密度下降了54 ± 1.3%。在选择性和非选择性实验中,雌性成虫都将真菌感染的蚜虫作为猎物,并在所有饥饿期避免将其作为食物来源。然而,未受真菌感染的活蚜虫和死蚜虫都被当作食物。这一结果揭示了雌蚜茧蜂与绵蚜茧蜂之间的相容性,这可能为在种植系统中有效管理棉蚜提供了一种可持续的策略。

Palpita forficifera Munroe, 1959 (Lepidoptera: Crambidae) is considered the main pest of the olive tree (Olea europaea L., Oleaceae) in Brazil and Uruguay. The aim of this work was to study the mating and oviposition behavior of P. forficifera in the field and laboratory. In the field, the sex emitting the mating pheromone was determined and in the laboratory, the rate of emergence of males and females; the age, time and duration of mating; number of copulations and oviposition time of P. forficifera were recorded. The field results showed that it was possible to capture up to five males per trap in just one night in traps with the presence of female P. forficifera. Copulation occurs between the seventh and twenty-third day of life and is most frequent during the third and sixth hours of scotophase. The average duration of the first copulation was 174 min, with 35% of couples recopulating, and there were cases of up to five copulations. Oviposition times were concentrated between 20:00 and 02:00. The results obtained provide insight into the reproductive behavior of P. forficifera and are useful for future studies aimed at identifying the sex pheromone to improve monitoring of the pest in olive orchards.

Palpita forficifera Munroe, 1959 (Lepidoptera: Crambidae) 被认为是巴西和乌拉圭橄榄树(Olea europaea L., Oleaceae)的主要害虫。这项工作的目的是研究 P. forficifera 在田间和实验室的交配和产卵行为。在田间,确定了发出交配信息素的性别;在实验室,记录了雌雄出现率;交配年龄、时间和持续时间;交配次数和 P. forficifera 的排卵时间。实地结果表明,在有雌性 P. forficifera 存在的诱捕器中,每个诱捕器一夜最多可捕获五只雄性 P. forficifera。交配发生在生命的第七天到第二十三天之间,在光照期的第三和第六个小时最为频繁。第一次交配的平均持续时间为 174 分钟,35% 的配偶会再次交配,有多达五次交配的情况。排卵时间集中在 20:00 至 02:00。研究结果有助于深入了解 P. forficifera 的繁殖行为,并有助于今后旨在确定性信息素的研究,从而改进对橄榄园中害虫的监测。

High Andean butterflies in northern South America are subject to landscape change processes. Our study used models to assess the habitat suitability of three Satyrinae species in the Upper Bogotá River Basin, Colombia. These three species include Pedaliodes polla (Thieme), Pedaliodes phaea (Hewitson), and Pedaliodes phaeina (Staudinger), the last two are endemic to Colombia. We used MaxEnt software to assess the habitat quality of these species, analyze the bioclimatic requirements that most influence them, and propose priority conservation areas. Our results indicated that, in most cases, the contribution of cover is more significant than 60%, so this variable determines the habitat capacity to support the species under study. We identified that the areas with suitable habitats are reduced with values less than or equal to 25% and are located in areas with a medium degree of intervention, which allows the species to occur. On the other hand, the climatic variables with the most significant contribution to the models were Temperature Seasonality and Precipitation of Driest Quarter (May-July). Conservation efforts must be focused on the most suitable areas, given the reduction in habitat for these species. Our research emphasizes the need to safeguard well-connected remnants of the high Andean forest and natural cover in agricultural matrices to counter the impact of agricultural expansion.

南美洲北部的安第斯高山蝴蝶受到地貌变化过程的影响。我们的研究利用模型评估了哥伦比亚波哥大河上游流域三个萨蒂林科物种的栖息地适宜性。这三个物种包括:Pedaliodes polla (Thieme)、Pedaliodes phaea (Hewitson) 和 Pedaliodes phaeina (Staudinger)。我们使用 MaxEnt 软件评估了这些物种的栖息地质量,分析了对它们影响最大的生物气候要求,并提出了优先保护区域。我们的结果表明,在大多数情况下,植被覆盖率的影响大于 60%,因此这一变量决定了栖息地支持所研究物种的能力。我们发现,适宜栖息地的面积减少了,其值小于或等于 25%,且位于干预程度中等的地区,这使得物种得以出现。另一方面,对模型贡献最大的气候变量是温度季节性和最干旱季度(5 月至 7 月)的降水量。鉴于这些物种栖息地的减少,保护工作必须侧重于最适合的地区。我们的研究强调,有必要保护安第斯高山森林的残余部分和农业区的自然植被,以抵御农业扩张的影响。

Diversity and Ecological Distribution of Plecoptera of Minas Gerais, Brazil. 巴西米纳斯吉拉斯州褶翅目昆虫的多样性和生态分布。
IF 1.4 3区 农林科学 Q2 ENTOMOLOGY Pub Date : 2024-08-01 Epub Date: 2024-07-05 DOI: 10.1007/s13744-024-01177-y

The order Plecoptera constitutes a relatively small group of aquatic insects, encompassing 17 extant families and comprising over 4400 valid species. In Brazil, the number of valid extant species is 207, located in two families: Perlidae (149) and Gripopterygidae (58). Despite extensive research on the southeastern region of Brazil, there is a notable scarcity of comprehensive studies consolidating geographical records and species richness of Plecoptera in the state of Minas Gerais. This study seeks to increase and refine our understanding of Plecoptera within Minas Gerais, focusing on its diversity and distribution. The initial phase involved a thorough review of articles documenting Plecoptera species in the state. Subsequently, biological material from the Museum of Entomology at the Federal University of Viçosa collection was meticulously identified, and its geographical records were incorporated. Utilizing this dataset, we compiled an updated list of Plecoptera species documented in Minas Gerais. Geographical coordinates of collection points were then mapped and graphically represented to elucidate the geographic and altitudinal distribution of these species. A total of 42 Plecoptera species were identified within the state of Minas Gerais, adding many occurrence records and documenting the first record of Gripopteryx pinima for the state. Despite these advancements, knowledge gaps persist, particularly in the mesoregions of Triângulo/Alto Paranaíba, Oeste de Minas, Vale do Mucuri, and Campo das Vertentes. This endeavor serves as an initial foundation to stimulate further collections and investments in undersampled areas, fostering future monitoring and conservation initiatives for aquatic environments.

褶翅目是一个相对较小的水生昆虫类群,包括 17 个现存科,有 4400 多个有效物种。在巴西,现存有效物种的数量为 207 个,分布在两个科中:鲈科(149 种)和蝶科(58 种)。尽管对巴西东南部地区进行了广泛的研究,但对米纳斯吉拉斯州褶翅目昆虫的地理记录和物种丰富度进行综合研究的成果却非常稀少。这项研究旨在增加和完善我们对米纳斯吉拉斯州褶翅目昆虫的了解,重点关注其多样性和分布。研究初期,我们对记录米纳斯吉拉斯州褶翅目物种的文章进行了全面审查。随后,对维索萨联邦大学昆虫学博物馆收藏的生物材料进行了细致的鉴定,并纳入了地理记录。利用这一数据集,我们编制了一份米纳斯吉拉斯州记录在案的褶翅目物种最新清单。然后,我们绘制了采集点的地理坐标图,并用图形表示,以阐明这些物种的地理和海拔分布情况。在米纳斯吉拉斯州共确定了42种褶翅目昆虫,增加了许多出现记录,并首次记录了该州的Gripopteryx pinima。尽管取得了这些进展,但知识差距依然存在,尤其是在Triângulo/Alto Paranaíba、Oeste de Minas、Vale do Mucuri和Campo das Vertentes等中生代地区。这项工作为促进在取样不足地区的进一步收集和投资奠定了初步基础,有助于今后对水生环境进行监测和保护。

Granuloviruses (GVs) Betabaculovirus associated with the fall armyworm (FAW), Spodoptera frugiperda (J.E. Smith) (Lepidoptera: Noctuidae), especially those of the type I, have scarcely been studied. These GVs might be an effective alternative for the biocontrol of this insect. In this study, the native GVs SfGV-CH13 and SfGV-CH28 were isolated from FAW larvae and characterized for morphology, molecular traits, and insecticidal activity. The elapsed time between symptomatic infection of larvae and stop feeding as well as the weight of larvae before death or prior to pupation were also evaluated. Both GVs had ovoid shape and a length of 0.4 µm. They had the same DNA restriction profiles and their genome sizes were about 126 kb. The symptomatic infection with the tested GVs mainly caused flaccidity of larva body and discoloration of integument. The integument lysis was only observed in 8% of infected larvae. Infected larvae gradually stopped feeding. Overall, these symptoms are characteristic of infections caused by type I GVs, which are known as monoorganotropic or slow-killing GVs. The median lethal dose (LD50) values for SfGV-CH13 and SfGV-CH28 isolates were 5.4 × 102 and 1.1 × 103 OBs/larva, respectively. The median lethal time (LT50) ranged from 17 to 24 days. LT50 values decreased as the viral dose was increased. The elapsed time from symptomatic infection until pupation and body weight of larvae (third instar) were higher with SfGV-CH28 than SfGV-CH13. Both granulovirus isolates were able to kill the FAW larvae from the 12th day.

与秋季军虫(FAW)Spodoptera frugiperda (J.E. Smith)(鳞翅目:夜蛾科)相关的颗粒病毒(GVs)Betabaculovirus,尤其是 I 型颗粒病毒,很少被研究。这些龙胆紫可能是生物控制这种昆虫的有效替代品。本研究从一窝蜂幼虫体内分离出了本地 GV SfGV-CH13 和 SfGV-CH28,并对其形态、分子特征和杀虫活性进行了鉴定。此外,还评估了从幼虫无症状感染到停止取食之间的时间间隔,以及幼虫死亡前或化蛹前的体重。两种 GV 都呈卵圆形,长度为 0.4 µm。它们具有相同的 DNA 限制性图谱,基因组大小约为 126 kb。被测 GVs 感染的症状主要是幼虫身体松弛和体表变色。只有 8%的受感染幼虫体表裂解。受感染的幼虫逐渐停止取食。总体而言,这些症状是 I 型 GVs 感染的特征,I 型 GVs 被称为单器官或慢杀性 GVs。SfGV-CH13 和 SfGV-CH28 分离物的中位致死剂量(LD50)值分别为 5.4 × 102 和 1.1 × 103 OBs/幼虫。中位致死时间(LT50)从 17 天到 24 天不等。LT50值随着病毒剂量的增加而降低。SfGV-CH28 从无症状感染到化蛹的时间和幼虫(第三龄)的体重均高于 SfGV-CH13。两种粒细胞病毒分离物都能从第 12 天起杀死一窝蜂幼虫。

Exploring Phylogenetic Relationships of the Mecocephala Group (Hemiptera: Pentatomidae) Using Continuous and Discrete Characters, with Notes on Taxonomy. 利用连续和离散特征探索 Mecocephala 组(半翅目:五蠹科)的系统发育关系,并附分类说明。
IF 1.4 3区 农林科学 Q2 ENTOMOLOGY Pub Date : 2024-08-01 Epub Date: 2024-07-02 DOI: 10.1007/s13744-024-01143-8

The Mecocephala group comprises about 50 species, restricted to the Neotropics and with the highest species richness in Neotropical South America. Several species use rice as host plants and their identification is facilitated by the presence of exaggerated head proportions and a unique male genitalic morphology. The taxonomy of the group has been extensively explored, but inferring its monophyly and especially its internal phylogenetic relationships has been challenging. Here, we inferred the phylogenetic relationships for the group assembling the most complete taxonomic sampling to date, analyzing discrete and continuous morphological characters through equal and implied weighted parsimony analyses. The monophyly of the group was recovered, but internal relationships varied slightly according to the dataset tested. Thus, we propose internal arrangements for the group and provide a formal description of the Mecocephala group, diagnoses for each genus, a dichotomous key to identify its genera, and illustrations of the morphological characters and type species.

Mecocephala 类包括约 50 个物种,局限于新热带地区,其中南美洲新热带地区的物种丰富度最高。有几个物种以水稻为寄主植物,它们的头部比例夸张,雄性生殖器形态独特,便于识别。人们对该类群的分类进行了广泛的探讨,但推断其单系,特别是其内部的系统发生关系一直是个难题。在此,我们收集了迄今为止最完整的分类学样本,通过等权和隐含加权解析分析离散和连续形态特征,推断了该类群的系统发生关系。该类群的单系得到恢复,但其内部关系因测试的数据集不同而略有差异。因此,我们提出了该类群的内部排列,并提供了 Mecocephala 类群的正式描述、各属的诊断、识别其属的二分法检索表以及形态特征和模式种的插图。

In holometabolous insects, the immature or larval stage is characterized by a high rate of food consumption. The nutrients obtained from which are directed towards the maintenance of metabolism, growth, pupation, and metamorphosis. However, when resources are scarce, the lack thereof can affect the growth rate and compromise the metamorphosis and formation of adults. Do increased energy expenditures yield outcomes similar to those resulting from restricted food intake during the larval stage? We hypothesized that removing the wax layer from the larvae of the ladybird Cryptolaemus montrouzieri Mulsant, 1850 would result in increased energy expenditure, which can compromise both larval growth and adult size. We compared the development time, feeding rate, and adult size of larvae with an intact wax layer, and those with constantly removed wax layers. We found that the production of the wax layer was continuous. Unlike the waxed larvae, the larvae of C. montrouzieri extended their development time in response to energy depletion through wax removal. The total number of mealybugs consumed by waxless larvae was higher than the total number consumed by waxed larvae; however, the daily consumption of waxless larvae was lower than that of waxed larvae. Furthermore, the adults of waxless larvae were smaller than those whose larvae had intact wax layers. This suggests that the cost associated with wax layer secretion is a pivotal factor in larval growth. Removing this layer does not get compensated by increased larval feeding or extended development time.

在全代谢昆虫中,未成熟期或幼虫期的特点是食物消耗量大。从中获得的营养用于维持新陈代谢、生长、化蛹和变态。然而,当资源匮乏时,缺乏资源会影响生长速度,影响成虫的变态和形成。增加能量消耗是否会产生与幼虫期限制食物摄入类似的结果?我们假设,去除瓢虫 Cryptolaemus montrouzieri Mulsant, 1850 幼虫的蜡质层会导致能量消耗增加,从而影响幼虫的生长和成虫的大小。我们比较了蜡层完整的幼虫和蜡层不断脱落的幼虫的发育时间、摄食率和成虫大小。我们发现,蜡层的产生是连续的。与脱蜡幼虫不同,C. montrouzieri 的幼虫在脱蜡导致能量消耗的情况下延长了发育时间。无蜡幼虫消耗的蚧壳虫总数高于有蜡幼虫;但无蜡幼虫的日消耗量低于有蜡幼虫。此外,与蜡层完整的幼虫相比,无蜡幼虫的成虫体型较小。这表明,与蜡层分泌有关的成本是影响幼虫生长的关键因素。去除蜡层并不能通过增加幼虫摄食量或延长发育时间来补偿。

Co-occurrence a correlation profiles are driven by different factors (exogenous and endogenous) and drawing a profile of association between species based on co-occurrence, without assessing how these species vary in terms of ecological niche can lead to wrong conclusions. The objective was to determine the co-occurrence and correlation patterns of phytophagous insects in canola crop and to evaluate how these patterns varied according to the crop stage (phenology-biotic) and sowing times (agricultural practice-abiotic). We found that the patterns of co-occurrence and correlation between species were reflections of population variations due to the phenology and sowing times of canola. Variations in the multi-species abundance matrix were influenced by mean air temperature and accumulated rainfall. The main species associated with canola in southern Brazil, in terms of abundance, were P. xylostella, D. speciosa, and N. viridula. These species were mostly negatively associated. When evaluating their population variations, we found that they explore different temporal niches, whether in terms of phenology or sowing times. Finally, we demonstrate empirically that despite being important, association patterns based on co-occurrence and correlation should be interpreted in light of the understanding of patterns of niche exploitation and temporal variation of species.

共现和相关模式受不同因素(外因和内因)的驱动,如果不评估这些物种在生态位方面的差异,就根据共现情况得出物种间的关联模式,可能会得出错误的结论。我们的目的是确定油菜作物中植食性昆虫的共生和相关模式,并评估这些模式如何随作物阶段(物候-生物)和播种时间(农业实践-非生物)而变化。我们发现,物种间的共现和相关模式反映了油菜花物候和播种时间导致的种群变化。多物种丰度矩阵的变化受到平均气温和累积降雨量的影响。就丰度而言,巴西南部与油菜籽相关的主要物种是 P. xylostella、D. speciosa 和 N. viridula。这些物种大多呈负相关。在评估它们的种群变化时,我们发现它们在物候学或播种时间方面探索了不同的时间壁龛。最后,我们通过经验证明,基于共生和相关性的关联模式尽管重要,但仍应根据对物种的生态位利用模式和时间变化的理解来解释。

Toxicological Assessments of Agrochemicals in Stingless Bees in Brazil: a Systematic Review. 巴西无刺蜂农用化学品毒理学评估:系统综述。
IF 1.4 3区 农林科学 Q2 ENTOMOLOGY Pub Date : 2024-06-01 Epub Date: 2024-02-15 DOI: 10.1007/s13744-024-01132-x

The growing concern with the decline of pollinators worldwide is centered on honey bees, due to their wide distribution, economic, and ecological importance. This type of concern remained less evident for stingless bees, which are widely distributed in the Neotropics, until recently. Since exposure to agrochemicals has been identified as one of the potential threats to bees, the present systematic review compiled information from toxicological evaluations in stingless bees in Brazil, home to a considerable portion of the existing species. This systematic review was performed considering species, research institutions, scientific journals, metrics, experimental set ups, and agrochemicals. The first article in this topic was published in 2010. Since then, 93 scientific papers were published, which showed that there are few species of stingless bees used for toxicological evaluations and Brazilian institutions lead these evaluations. Only 1.5% of the stingless bees' species that occur in Brazil were assessed through chronic exposure in the larval stage. The Universidade Federal de Viçosa (UFV) is responsible for 37% of the total publications. The main route of exposure was acute, using adults in laboratory conditions. The main group of agrochemicals studied were insecticides, in particular the neonicotinoids. The current results reveal the advances achieved and point out the gaps that still need to be filled considering toxicological evaluations in stingless bees.

由于蜜蜂的广泛分布、经济和生态重要性,全球范围内对传粉媒介减少的关注日益集中在蜜蜂身上。直到最近,人们对广泛分布于新热带地区的无刺蜜蜂的关注才有所减少。由于接触农用化学品已被确定为蜜蜂面临的潜在威胁之一,本系统综述汇编了巴西无刺蜂毒理学评估的信息,巴西是相当一部分现有物种的故乡。本系统综述考虑了物种、研究机构、科学期刊、指标、实验装置和农用化学品。该主题的第一篇文章发表于 2010 年。从那时起,共发表了 93 篇科学论文,这些论文表明,用于毒理学评估的无刺蜜蜂种类很少,这些评估由巴西机构主导。在巴西出现的无刺蜜蜂中,只有1.5%的种类在幼虫阶段通过慢性接触进行了评估。维索萨联邦大学(UFV)发表的论文占论文总数的37%。主要的接触途径是急性接触,使用的是实验室条件下的成虫。研究的主要农用化学品是杀虫剂,特别是新烟碱类。目前的研究结果表明了所取得的进展,并指出了在无刺蜜蜂毒理学评估方面仍需填补的空白。
