Herbivorous insects depend on the host plant to optimize their overall reproductive success, and balanced fertilization may alter the plant's quality against herbivory. Life history traits of the Liriomyza trifolii (Burgess) were determined under laboratory conditions using either unfertilized and fertilized plants of bean [Phaseolus vulgaris L. (Fabaceae)], chrysanthemum [Chrysanthemum × morifolium (Asteraceae)], potato [Solanum tuberosum (Solanaceae)], bell pepper [Capsicum annuum (Solanaceae)], and tomato [Solanum lycopersicum (Solanaceae)]. Results indicated that L. trifolii completed development on all studied unfertilized and fertilized plants. Nevertheless, a higher performance of the leaf miner was observed on bean and bell pepper plants compared to the other plants. Furthermore, there was an interaction of the host plant and fertilization with Calcium Aria or Sitam negatively affecting the fitness-related traits of the leaf miner. Application of these fertilizers resulted in delayed immature development of L. trifolii, decreased survival rate, and reduced adult longevity and fecundity. The activity of cinnamyl alcohol dehydrogenase (CAD), peroxidase (POD), polyphenol oxidase (PPO), and phenylalanine ammonia-lyase (PAL) enzymes, as well as phenolic, flavonoid, and lignin content were higher in Calcium Aria + Sitam fertilized plants, intermediate in Calcium Aria and Sitam treated plants, and the lower in unfertilized plants. The development and survival of L. trifolii on different host plants, considering fertilization options, become important for deploying cultural control practices against this important pest species.

食草昆虫依赖寄主植物来优化其整体繁殖成功率,而均衡施肥可能会改变植物的质量,使其免受食草昆虫的侵害。在实验室条件下,使用未施肥和已施肥的豆科植物[Phaseolus vulgaris L. (豆科植物)]、菊科植物[Chryshemum L. (菊科植物)]和[Phaseolus vulgaris L. (豆科植物)]植物,测定了三叶蓟马(Liriomyza trifolii,Burgess)的生活史特征。(菊花 × morifolium(菊科)]、马铃薯[Solanum tuberosum(茄科)]、甜椒[Capsicum annuum(茄科)]和番茄[Solanum lycopersicum(茄科)]。结果表明,L. trifolii 在所有研究的未施肥和施肥植株上都完成了发育。不过,与其他植物相比,菜豆和甜椒植株上的潜叶蝇表现更强。此外,寄主植物与施用钙咏叹调或西塔姆肥料之间存在相互作用,对潜叶蝇的适应性相关性状产生了负面影响。施用这些肥料会导致 L. trifolii 的未成熟发育延迟、存活率下降、成虫寿命和繁殖力降低。钙咏叹调+西坦姆施肥植株的肉桂醇脱氢酶(CAD)、过氧化物酶(POD)、多酚氧化酶(PPO)和苯丙氨酸氨化酶(PAL)活性以及酚类、黄酮类和木质素含量较高,钙咏叹调和西坦姆处理植株居中,未施肥植株较低。考虑到施肥方案,三叶蓟马在不同寄主植物上的发育和存活情况对于针对这种重要害虫采取文化控制措施非常重要。

Anastrepha fraterculus (Diptera: Tephritidae) is considered an important pest in Neotropical countries. The laboratory rearing of this species should reproduce conditions in nature; thus, special attention is required to the nutritional quality of diets for larval development. Protein components (wheat germ) are costly and account for most production costs in lab insect rearing. In this sense, this work aimed to identify ingredients to replace wheat germ, without compromising diet quality for the lab rearing of A. fraterculus. We tested diets composed of whole rice flour, corn flour, and a mixture of whole wheat flour + soybean flour as substitutes for wheat germ as well as a raw wheat germ diet, considered the control. The protein sources used in the larval diet influenced the biological performance of both the larval and adult stages of A. fraterculus during six generations. The diet containing corn flour and wheat germ showed similar results in the different developmental parameters. The diet with rice flour also provided adequate biological development for A. fraterculus throughout its life cycle and was nutritionally similar to the control. As it is local product, rice flour can replace wheat germ (costly imported product) in artificial diets for A. fraterculus, reducing production costs by roughly 30% without compromising the biological and nutritional parameters of the insects. Faced with this, the rice flour can be considered suitable for the mass rearing of A. fraterculus in the laboratory.

Anastrepha fraterculus(双翅目:Tephritidae)被认为是新热带国家的一种重要害虫。该物种的实验室饲养应再现自然条件,因此需要特别注意幼虫发育所需的日粮营养质量。蛋白质成分(小麦胚芽)成本较高,占实验室昆虫饲养生产成本的大部分。从这个意义上说,这项工作旨在确定可替代小麦胚芽的成分,同时不影响实验室饲养叶蝉的日粮质量。我们测试了由全米粉、玉米粉和全麦粉+大豆粉的混合物组成的日粮,作为小麦胚芽的替代品,以及作为对照的生小麦胚芽日粮。幼虫日粮中使用的蛋白质来源影响了六代叶蝉幼虫和成虫阶段的生物学表现。含玉米粉和小麦胚芽的日粮在不同发育参数上表现出相似的结果。含米粉的日粮也能使叶蝉在整个生命周期中得到充分的生物发育,其营养成分与对照组相似。由于米粉是本地产品,它可以替代小麦胚芽(昂贵的进口产品)用于叶蝉的人工日粮,在不影响昆虫生物和营养参数的情况下,可降低约 30% 的生产成本。因此,可以认为米粉适合在实验室中大量饲养稻飞虱。

World trade has facilitated the spread of non-native pest species, presenting new challenges for food production. In the Global South, linking worker social protection programs with invasive pest management can, at the same time, contribute to food security and empower workers. The spotted wing Drosophila (Drosophila suzukii) (SWD) recent invasion in the Global South case study illustrates how science-based policies integrated with agricultural worker-based social organizations can contribute toward economic and environmental sustainability.

The Neotropical genus Ebenia Macquart, 1846, is a member of the tribe Dufouriini (Dexiinae), and before the current work, comprised four species, viz. E. claripennis Macquart 1846, E. fumata (Wulp, 1891), E. neofumata Santis & Nihei, 2022 and E. trichopoda (Wulp, 1891). The present taxonomic revision results in a new generic synonymy: Comyops Wulp, 1891 syn. nov. of Ebenia. The following two new combinations result from this act: E. nigripennis (Wulp, 1891) comb. nov. and E. striaticollis (Wulp, 1891) comb. nov. both originally described in Comyops. In addition, the species originally described as Homodexia spinosa Bigot, 1889 is moved from its current placement in Thelairodes Wulp, 1891 to Ebenia as Ebenia spinosa (Bigot, 1889) comb. nov. A new specific synonymy is proposed for this last species: Morinia trichopoda Wulp, 1891, previously treated as a valid species of Ebenia, becomes a junior synonym of E. spinosa. All valid species are redescribed and photographed with the first description and illustration of the male terminalia for E. claripennis, E. neofumata and E. nigripennis and female terminalia for E. spinosa. Additionally, lectotype fixations are made for E. nigripennis and M. trichopoda. Finally, an updated diagnosis for the genus Ebenia and a key to the six known species are provided.

Globally, people use sugarcane (Saccharum officinarum) to produce sugar and ethanol. Rainfed or irrigated sugarcane agricultural systems are available. Among the pests affecting this crop, the weevil Sphenophorus levis, Vaurie 1978 (Coleoptera: Curculionidae), is increasingly becoming a significant threat in southern South America. Sphenophorus levis populations are controlled using chemical or biological measures. Control decisions hinge upon the economic injury level (EIL). The EIL delineates the pest density that results in financial losses for producers. This study aims to determine the EIL for S. levis, considering the factors favoring this insect pest and chemical and biological control methods in rainfed and irrigated systems. The intensity of S. levis attacks was monitored in commercial sugarcane plantations over four years in João Pinheiro, Minas Gerais, Brazil. Sampling occurred in a 50 × 50 × 30-cm-deep trench dug in the soil surrounding the sugarcane clump. The total number of stumps in the clump, including those attacked by S. levis, was tallied. The EILs for this pest were 5.93% and 4.85% of targeted stumps for chemical control in rainfed and irrigated crops, respectively. Biological control in sugarcane plots resulted in an EIL of 4.15% and 3.40% for stumps attacked in rainfed and irrigated crops, respectively. Pest attacks were more severe during rainy years and in older sugarcane crops. The EIL values determined in this study could inform integrated pest management programs for sugarcane crops.

在全球范围内,人们利用甘蔗(Saccharum officinarum)生产糖和乙醇。甘蔗农业系统有雨水灌溉和灌溉两种。在影响这种作物的害虫中,象鼻虫 Sphenophorus levis,Vaurie 1978(鞘翅目:蝼蛄)正日益成为南美洲南部的一个重大威胁。Sphenophorus levis 的数量是通过化学或生物措施控制的。控制决策取决于经济损失水平(EIL)。经济损失水平划定了导致生产者经济损失的害虫密度。本研究旨在确定莱维斯虫害的经济损失水平,同时考虑到有利于这种害虫的因素以及雨养和灌溉系统中的化学和生物防治方法。研究人员在巴西米纳斯吉拉斯州若昂-皮涅罗的商业甘蔗种植园中监测了四年来莱维斯甘蔗虫害的强度。取样在甘蔗丛周围土壤中挖出的 50 × 50 × 30 厘米深的沟中进行。统计甘蔗丛中树桩的总数,包括受莱维斯虫侵害的树桩。在雨水灌溉和灌溉作物中,该害虫的 EIL 分别为化学防治目标树桩的 5.93% 和 4.85%。在甘蔗地块进行生物防治后,雨水灌溉和灌溉作物受侵害树桩的 EIL 分别为 4.15%和 3.40%。多雨年份和老甘蔗作物的虫害更为严重。本研究确定的 EIL 值可为甘蔗作物的虫害综合防治计划提供参考。

Increased attention is being focused on the biological control of agricultural pests using microorganisms, owing to their potential as a viable substitute for chemical control methods. Insect cadavers constitute a potential source of entomopathogenic microorganisms. We tested whether bacteria and fungi isolated from Spodoptera frugiperda (JE Smith) cadavers could affect its survival, development, egg-laying pattern, and hatchability, as well as induce mortality in Anthonomus grandis Boheman adults. We isolated the bacteria Enterobacter hormaechei and Serratia marcescens and the fungi Scopulariopsis sp. and Aspergillus nomiae from fall armyworm cadavers and the pest insects were subjected to an artificial diet enriched with bacteria cells or fungal spores to be tested, in the case of S. frugiperda, and only fungal spores in the case of A. grandis. Enterobacter hormaechei and A. nomiae were pathogenic to S. frugiperda, affecting the survival of adults and pupae. The fungus Scopulariopsis sp. does not affect the survival of S. frugiperda caterpillars and pupae; however, due to late action, moths and eggs may be affected. Aspergillus nomiae also increased mortality of A. grandis adults, as well as the development of S. frugiperda in the early stages of exposure to the diet, as indicated by the vertical spore transfer to offspring and low hatchability. Enterobacter hormaechei and A. nomiae are potential biocontrol agents for these pests, and warrant further investigation from a toxicological point of view and subsequently in field tests involving formulations that could improve agricultural sustainability practices.

由于微生物具有替代化学防治方法的潜力,人们越来越关注利用微生物对农业害虫进行生物防治。昆虫尸体是昆虫病原微生物的潜在来源。我们测试了从 Spodoptera frugiperda (JE Smith) 尸体中分离出的细菌和真菌是否会影响其生存、发育、产卵模式和孵化率,以及是否会诱导 Anthonomus grandis Boheman 成虫死亡。我们从秋季军虫尸体中分离出了肠杆菌和沙雷氏菌,以及真菌 Scopulariopsis sp.荷马肠杆菌(Enterobacter hormaechei)和A. nomiae对S. frugiperda具有致病性,影响成虫和蛹的存活。真菌 Scopulariopsis sp.不会影响 S. frugiperda 毛虫和蛹的存活;但由于作用较晚,蛾和卵可能会受到影响。曲霉菌(Aspergillus nomiae)也会增加大青虫成虫的死亡率,并在暴露于食物的早期阶段影响 S. frugiperda 的发育,表现为垂直孢子转移到后代和低孵化率。荷马肠杆菌和 A. nomiae 是这些害虫的潜在生物控制剂,值得从毒理学的角度进行进一步研究,并随后在涉及可改善农业可持续性做法的配方的田间试验中进行研究。

The house fly, Musca domestica (Linnaeus) (Diptera: Muscidae), is a significant threat to human and animal health and is also resistant to a variety of insecticides. Plant-derived benzoates are known to have insecticidal activities against various insects. In this study, the larvicidal, pupicidal, and adulticidal activities of benzoate derivatives (benzyl alcohol BA, benzyl benzoate BB, and methyl benzoate MB) were assessed and investigated for their effects on larval structure and acetylcholinesterase activity. Six concentrations (2.5 to 100 mg/mL) of benzoate derivatives were applied to larvae and pupae through the residual film method and topical application, respectively. Meanwhile, concentrations from 0.625 to 50 mg/L air were applied to adult flies through a fumigation assay. BA and MB achieved promising results against larvae with LC50 values of 10.90 and 11.53 mg/mL, respectively. Moreover, BA killed 100% of the larvae at a concentration of 25 mg/mL, and MB achieved the same effect at a concentration of 50 mg/mL. Regarding the pupicidal activity, MB showed a percentage inhibition rate (PIR) of 100% at a concentration of 100 mg/mL, while the same effect was achieved by BA at a concentration of 50 mg/mL. Meanwhile, BB did not show any effect on the larvae or pupae at any of the tested concentrations. Moreover, the scanning microscopy observations on the treated larvae by BA and MB estimated flaccid and deformity in the larva body with a shrunken cuticle. Additionally, both BA and MB suppress nerve signal transmission by inhibiting acetylcholinesterase. In conclusion, the results of this study indicate that BA and MB may be useful in control housefly populations. These substances cause severe muscular relaxation and deformities in insects.

家蝇(Musca domestica (Linnaeus))(双翅目:鹟科)对人类和动物健康构成严重威胁,而且对多种杀虫剂具有抗药性。已知植物源苯甲酸盐对多种昆虫具有杀虫活性。本研究评估了苯甲酸酯衍生物(苯甲醇 BA、苯甲酸苄酯 BB 和苯甲酸甲酯 MB)的杀幼虫、杀蛹和杀成虫活性,并研究了它们对幼虫结构和乙酰胆碱酯酶活性的影响。通过残膜法和局部施用法,分别对幼虫和蛹施用了六种浓度(2.5 至 100 毫克/毫升)的苯甲酸酯衍生物。同时,通过熏蒸试验对成蝇施用了 0.625 至 50 毫克/升空气浓度的苯甲酸酯衍生物。BA 和 MB 对幼虫的半数致死浓度分别为 10.90 毫克/毫升和 11.53 毫克/毫升,取得了良好的效果。此外,当浓度为 25 毫克/毫升时,BA 能杀死 100%的幼虫,而当浓度为 50 毫克/毫升时,MB 也能达到同样的效果。关于杀蛹活性,浓度为 100 毫克/毫升时,MB 的抑制率(PIR)为 100%,而浓度为 50 毫克/毫升时,BA 也达到了同样的效果。同时,在任何测试浓度下,BB 对幼虫或蛹都没有任何影响。此外,通过扫描显微镜观察 BA 和 MB 处理过的幼虫,发现幼虫身体松弛畸形,角质层萎缩。此外,BA 和 MB 还能通过抑制乙酰胆碱酯酶来抑制神经信号的传递。总之,这项研究的结果表明,BA 和 MB 可用于控制家蝇种群。这些物质会导致昆虫肌肉严重松弛和畸形。

Assessing the Impact of Climate Change on Argyrotaenia sphaleropa (Meyrick, 1909) Voltinism: Implications for Fruit Production in Southern Brazil. 评估气候变化对 Argyrotaenia sphaleropa(Meyrick,1909 年)瘤胃的影响:对巴西南部水果生产的影响。

The leafroller Argyrotaenia sphaleropa (Meyrick) is an important pest of temperate fruits. Its biology and population dynamics are strongly influenced by temperature. In this context, this study aims to select a mathematical model that accurately describes the temperature-dependent development rate of A. sphaleropa and applies this model to predict the impact of climate change on the number of annual generations (voltinism) of the pest in southern Brazil. Nine mathematical models were employed to fit the species' developmental rate at different constant temperatures. Voltinism was projected using climate data from the current period (1994-2013) and projections for 2050 and 2070. The Brière-1 model (D(T) = aT(T-TL)(TH-T)1/2) provided the best fit for the temperature-dependent developmental rate of A. sphaleropa. According to this model, the regions with the highest voltinism under current climatic conditions are the northern and central areas of Paraná, the western and northeastern regions of Santa Catarina, and northwestern Rio Grande do Sul. The model also predicts a rise in A. sphaleropa voltinism as a consequence of climate change, especially in the mountainous regions of Santa Catarina and Rio Grande do Sul, with projected increases of up to 25.1%. These regions encompass most areas where temperate fruits used as hosts by the leafroller are cultivated. This study represents a significant advancement in understanding the implications of global warming on A. sphaleropa voltinism and suggests that forthcoming climatic conditions will likely favor the species across much of southern Brazil.

卷叶虫 Argyrotaenia sphaleropa(Meyrick)是温带水果的一种重要害虫。它的生物学特性和种群动态受温度影响很大。在这种情况下,本研究旨在选择一种数学模型,以准确描述卷叶虫随温度变化的发育速度,并应用该模型预测气候变化对巴西南部该害虫年世代数(伏期)的影响。该研究采用了九个数学模型来拟合该物种在不同恒定温度下的发育速度。利用当前时期(1994-2013 年)的气候数据以及 2050 年和 2070 年的预测数据对伏旱进行了预测。Brière-1模型(D(T)= aT(T-TL)(TH-T)1/2)最能拟合随温度变化的蛛形纲发育率。根据该模型,在目前的气候条件下,巴拉那州北部和中部地区、圣卡塔琳娜州西部和东北部地区以及南里奥格兰德州西北部地区的伏缺率最高。该模型还预测,由于气候变化的影响,A. sphaleropa 伏旱现象会加剧,尤其是在圣卡塔琳娜州和南里奥格兰德州的山区,预计增幅高达 25.1%。这些地区涵盖了大部分被卷叶虫用作寄主的温带水果种植区。这项研究标志着在了解全球变暖对A. sphaleropa卷叶虫影响方面取得了重大进展,并表明即将到来的气候条件很可能有利于巴西南部大部分地区的该物种。
