Patanga japonica (Bolívar) shows various body colors in the field. Most nymphs are green in the summer, but some develop non-green colors, such as yellow, white, brown, reddish, and black, in the fall. Nymphs individually reared in white, yellow-green, and black containers showed green, light-green, white, and reddish body colors, and the substrate color significantly influenced the proportions of green nymphs. A few individuals developed black spots and patterns, and such individuals were most frequently observed in the black containers. Nymphs with distinct black patterns were observed when reared in a group of five individuals per container, and the proportion of such individuals varied slightly depending on the brightness of the substrate color. Singly kept nymphs that were allowed to see five other nymphs in another container turned darker than those that were only allowed to see an empty container, suggesting that visual stimuli without mechanical stimulation induced black patterns. In outdoor cages, nymphs tended to develop more pronounced black patterns during their last instar when the hatching date was delayed and the temperature during the later stages of development was decreased. The effect of temperature during the late stadia was tested by transferring a group of third-stadium nymphs from outdoor cool conditions to a high temperature, while other nymphs were continuously maintained outdoors. Markedly melanized individuals were observed in the outdoor cage, whereas the appearance of such individuals was strongly suppressed at a high temperature. Green nymphs injected with synthetic [His7]-corazonin developed black patterns after ecdysis to the following instars and to the adult stage, and some looked indistinguishable in body color from group-reared nymphs. Nymphs injected with this hormone developed black patterns even at a high temperature. Adults looked similar in body coloration with some variation. Their hindwings turned reddish after overwintering. These results demonstrate that P. japonica exhibits body-color pholyphenism.
Patanga japonica(Bolívar)在田间呈现出不同的体色。大多数若虫在夏季是绿色的,但有些若虫在秋季会出现非绿色的体色,如黄色、白色、棕色、淡红色和黑色。在白色、黄绿色和黑色容器中单独饲养的若虫体色有绿色、浅绿色、白色和淡红色,基质颜色对绿色若虫的比例有显著影响。少数个体出现黑色斑点和花纹,这些个体在黑色容器中最常见。当每个容器中饲养 5 只若虫时,可观察到带有明显黑色花纹的若虫,这些若虫的比例因基质颜色的亮度而略有不同。单独饲养的若虫如果能看到另一个容器中的其他五只若虫,则比只能看到空容器的若虫颜色更深,这表明视觉刺激而非机械刺激会诱发黑色花纹。在室外笼中,当孵化日期推迟和发育后期温度降低时,若虫在最后一龄往往会出现更明显的黑色花纹。通过将一组第三阶段的若虫从室外低温环境转移到高温环境,同时将其他若虫持续放在室外,测试了后期阶段温度的影响。在室外笼子中观察到了明显黑色化的个体,而在高温条件下这些个体的出现受到了强烈抑制。注射了合成[His7]-corazonin的绿色若虫在蜕皮后到随后的蜕皮期和成虫期都会出现黑色花纹,有些若虫的体色与群体饲养的若虫没有区别。注射了这种激素的若虫即使在高温下也会出现黑色花纹。成虫的体色看起来相似,但也有一些差异。它们的后翅在越冬后变成淡红色。这些结果表明日本鸦雀具有体色多色性。

Extant pygmy grasshoppers (Tetrigidae) that possess wings have the forewings reduced into scale-like tegmenula, while hind wings remain fully developed. Rusmithia gorochovigen. et sp. nov. (Tetrigidae, Batrachideinae, Rusmithinitrib. nov.) is described based on a single adult female holotype from Lithuanian Baltic amber, from the Bartonian-Priabonian age, some 40 million years ago, and this is the only known tetrigid in which tegmenula or tegmina (the forewings) extend as far as half the length of the hind femur. Besides this very unique trait, other characters of Rusmithiagen. nov. indicate similarity with extant and especially fossil Batrachideinae (genus Danatettix Thomas, Skejo & Heads, 2019). Because of the strong differences this genus and Danatettix have with American Batrachideinae, they are assigned to a new tribe, European Batrachideinae or Rusmithinitrib. nov.Acrydium bachofeni (Zeuner, 1937) might belong to this or a sibling genus based on its very long tegmenula or Succinotettix chopardi Piton, 1938, based on its 19-segmented antennae; neither species is tranferred as their types could not be examined.
现存的侏儒蚱蜢(Tetrigidae)具有翅膀,但前翅退化为鳞片状的tegmenula,后翅仍然发育完全。Rusmithia gorochovigen. et sp. nov. (Tetrigidae, Batrachideinae, Rusmithinitrib. nov.)是根据立陶宛波罗的海琥珀中的一个成年雌性主模式描述的,该琥珀来自距今约 4000 万年前的巴顿-普里阿本纪,这是已知的唯一一种前翅延伸至后股骨一半长度的蚱蜢。除了这一非常独特的特征外,Rusmithiagen. nov.的其他特征也表明其与现生的,尤其是化石中的Batrachideinae(Danatettix Thomas, Skejo & Heads, 2019属)具有相似性。Acrydium bachofeni (Zeuner, 1937) 根据其很长的tegmenula或 Succinotettix chopardi Piton, 1938,根据其 19 节触角,可能属于该属或其同胞属;由于无法检验其模式标本,这两个种均未转入。

Many grasshopper species produce conspicuous sounds while escaping from approaching predators; however, they occasionally escape without producing sounds. The Chinese grasshopper, Acrida cinerea, often exhibits noisy escape behavior. Therefore, a field experiment was conducted using A. cinerea to identify factors related to the production of sound during escape. This study utilized a predator model with an investigator approaching A. cinerea three times. We examined the relationship between the production of sound during escape and the following factors: ambient temperature and relative humidity as environmental factors; sex, body length, body weight, and limb autotomy as prey traits; and the repeated approach as a predator trait. The relationships between noisy escape and flight initiation distance (i.e., predator-prey distance when the prey initiates the escape), distance fled (i.e., distance the prey covered during the escape), and the mode of locomotion during escape (i.e., flying or jumping) were also examined. Noisy escape was observed only in males that escaped by flying, whereas the females and males that escaped by jumping invariably escaped silently. Among males that flew, noisy escape was related to ambient temperature, limb autotomy, and distance fled. The proportion that produced sound increased in parallel with the ambient temperature and distance fled. This proportion was lower among individuals that had autotomized one of their hind legs. These results indicate that noisy escape behavior is most frequent in healthy male A. cinerea under warm conditions.
许多蚱蜢物种在逃离接近的捕食者时都会发出明显的声音;不过,它们偶尔也会在不发出声音的情况下逃跑。中国蚱蜢(Acrida cinerea)经常表现出嘈杂的逃跑行为。因此,我们利用中华蚱蜢进行了一项野外实验,以确定与逃跑时发出声音有关的因素。这项研究采用了捕食者模型,研究人员三次接近 A. cinerea。我们研究了逃逸过程中声音的产生与以下因素之间的关系:环境因素中的环境温度和相对湿度;猎物特征中的性别、体长、体重和肢体自切;捕食者特征中的重复接近。此外,还研究了噪声逃逸与逃逸开始距离(即猎物开始逃逸时捕食者与猎物之间的距离)、逃逸距离(即猎物在逃逸过程中的距离)以及逃逸过程中的运动方式(即飞行还是跳跃)之间的关系。只有用飞的方式逃跑的雄性才会发出嘈杂的逃跑声,而用跳的方式逃跑的雌性和雄性都是无声逃跑。在飞行逃跑的雄性中,发出声音的逃跑与环境温度、肢体自转和逃跑距离有关。发出声音的比例随着环境温度和逃跑距离的增加而增加。后肢自动切除的个体发出声音的比例较低。这些结果表明,在温暖条件下,健康雄性银环蛇最常见的是发出声音的逃跑行为。

Geographic variation in body size of the migratory locust Locusta migratoria (Orthoptera, Acrididae): Masaki’s cline and phase polyphenism 迁徙蝗虫 Locusta migratoria(直翅目,蝼蛄科)体型的地理变异:Masaki cline 和相位多态性

Adults of the migratory locust Locusta migratoria (Linnaeus, 1758) were collected in the Japanese Archipelago, which extends from the Ryukyu subtropical region to the Hokkaido cool-temperate region, covering more than 2,500 km. A saw-toothed pattern was observed in body size along the latitudinal or annual mean temperature gradient, which is similar to Masaki’s clines initially described for crickets. The latitudinal cline of locusts was also observed in the laboratory, suggesting that this cline was primarily due to genetic variation. In the northern univoltine zone, locust body size increased toward the south. The latitudinal size trend was reversed in the transitional zones where the voltinism shifted from univoltine to bivoltine and from bivoltine to trivoltine life cycles. These patterns may be explained by changes in the length of the growing season for development and reproduction. Body size varied with growth efficiency but not with the variable lengths of nymphal development. Larger females had more ovarioles and produced fatter egg pods containing more eggs per pod. The morphometric ratio, F/C (hind femur length/head width), tended to decrease with latitude, but this characteristic could be primarily due to phylogenetic differences between the northern and southern clades. It was confirmed that F/C ratio decreased when the locusts were reared in a group. The sexual size dimorphism, or SSD, tended to increase as the mean body sizes of populations increased, converse to Rensch’s rule. The relative body size of females and males correlated with latitude and was greatly reduced when the insects were reared in a group. The smaller rate of increase at higher latitudes may be related to male–female associations and predation pressure.
从琉球亚热带地区到北海道寒温带地区,日本列岛上的迁徙蝗虫(Locusta migratoria,Linnaeus,1758 年)的成虫被采集了 2,500 多公里。沿纬度或年平均温度梯度观察到体型呈锯齿状,这与 Masaki 最初描述的蟋蟀纬线相似。在实验室中也观察到了蝗虫的纬度曲线,这表明这种曲线主要是由遗传变异造成的。在北部单伏区,蝗虫的体型向南增大。在过渡区,体型的纬度趋势发生了逆转,在过渡区,蝗虫的生命周期从单伏转向双伏,从双伏转向三伏。这些模式可以用发育和繁殖的生长季节长度的变化来解释。体型随生长效率的变化而变化,但不随若虫发育时间的变化而变化。体型较大的雌虫有更多的卵巢,结出的卵荚也更肥大,每个卵荚含有更多的卵。形态比F/C(后股骨长/头宽)随着纬度的变化呈下降趋势,但这一特征可能主要是由于北方和南方支系之间的系统发育差异造成的。研究证实,当蝗虫群养时,F/C比值会降低。随着种群平均体型的增加,性体型二态性(SSD)也呈上升趋势,这与伦施法则相反。雌性和雄性的相对体型与纬度有关,当昆虫被群养时,雌性和雄性的相对体型会大大缩小。纬度越高,增长速度越小,这可能与雌雄结合和捕食压力有关。

Patterns of morphological divergence across species’ ranges can provide insight into local adaptation and speciation. In this study, we compared phenotypic divergence among 4,221 crickets from 337 populations of two closely related species of field cricket, Gryllus firmus and G. pennsylvanicus , and their hybrids. We found that these species differ across their geographic range in key morphological traits, such as body size and ovipositor length, and we directly compared phenotype with genotype for a subset of crickets to demonstrate nuclear genetic introgression, phenotypic intermediacy of hybrids, and essentially unidirectional mitochondrial introgression. We discuss how these morphological traits relate to life history differences between the two species. Our comparisons across geographic areas support prior research suggesting that cryptic variation within G. firmus may represent different species. Our study highlights how variable morphology can be across wide-ranging species and the importance of studying reproductive barriers in more than one or two transects of a hybrid zone.
跨物种范围的形态差异模式可以提供对局部适应和物种形成的见解。本研究比较了野地蟋蟀(Gryllus firmus和G. pennsylvanicus)及其杂种337个居群的4221只蟋蟀的表型差异。我们发现这些物种在其地理范围内的关键形态特征(如体型和产卵器长度)存在差异,并且我们直接比较了蟋蟀的一个子集的表型和基因型,以证明核遗传渗入,杂交的表型中间性,以及本质上单向的线粒体渗入。我们讨论了这些形态特征如何与两个物种之间的生活史差异有关。我们跨地理区域的比较支持了先前的研究,表明G. firus内部的隐变可能代表不同的物种。我们的研究强调了如何在广泛的物种中改变形态,以及在杂交带的一个或两个以上的样带中研究生殖障碍的重要性。

Scattered taxonomic data can be used to determine the geographic distribution of arthropods such as Mantodea (mantids). The distribution of mantids is not well known in Iran and not readily determined because the literature has been published in a mix of Persian-language and non-Persian-language scientific references, including books, journals, annual congress proceedings, and final reports of academic projects. To create a national checklist of mantids in Iran, I reviewed 35 Persian and non-Persian (English, German, and Italian) publications. I recorded 57 praying mantid species from 9 families described from localities across Iran. I identified 18 species— Ameles decolor , Ameles heldreichi , Ameles picteti , Ameles spallanzania , Elaea marchali , Empusa pennata , Eremiaphila andresi , Eremiaphila cerisy , Eremiaphila turcica , Geomantis larvoides , Iris coeca , Iris pitcheri , Oxyothespis wagneri , Pareuthyphlebs palmonii , Pseudoyersinia paui , Rivetina baetica , Severinia nigrofasciata , and Severinia turcomaniae —with records in Iran that may be incorrect based on geographic ranges that do not include Iran and similarity to other species that do occur in Iran. In the proposed checklist comprising 39 species, the family Rivetinidae, with 9 species, and the 2 families Amorphoscelidae and Nanomantidae, with 1 species each, comprised the greatest and least diversity, respectively. This checklist can facilitate future studies on Iran’s mantodeans.
分散的分类资料可用于确定Mantodea(螳螂)等节肢动物的地理分布。螳螂在伊朗的分布并不为人所知,也不容易确定,因为这些文献发表在波斯语和非波斯语的科学参考文献中,包括书籍、期刊、年度会议记录和学术项目的最终报告。为了创建一份伊朗螳螂的国家清单,我查阅了35份波斯语和非波斯语(英语、德语和意大利语)出版物。我记录了来自伊朗各地9个科的57种螳螂。共鉴定出18个物种,分别是:脱色阿梅莱斯、heldreichi阿梅莱斯、picteti阿梅莱斯、spallanzania阿梅莱斯、emea marchali、Empusa pennata、eremiphila andresi、eremiphila cerisy、eremiphila turcica、Geomantis larvoides、coeca、Iris pitcheri、Oxyothespis wagneri、Pareuthyphlebs palmonii、Pseudoyersinia paui、Rivetina baetica、Severinia nigrofasciata、以及Severinia turcomaniae——在伊朗的记录可能是不正确的,因为地理范围不包括伊朗,而且与在伊朗出现的其他物种相似。在39种昆虫中,Rivetinidae科(9种)和Amorphoscelidae科(1种)和Nanomantidae科(1种)的多样性最大。这份清单可以促进未来对伊朗螳螂的研究。

The winged stick insect Metriophasma iphicles (Redtenbacher, 1906) (Phasmatodea: Pseudophasmatidae) is recorded for the first time from Mexico (state of Veracruz), making this the northernmost record of both the species and genus. A checklist of species in the family Pseudophasmatidae from Mexico and the USA is presented, and a key to the species listed is proposed. With the current record, the number of continental North American species of Phasmatodea increases to 108, and the number of genera in the region increases to 23.

Geographic variation in the calling songs and genetics of Bartram’s round-winged katydid Amblycorypha bartrami (Tettigoniidae, Phaneropterinae) reveal new species Geographic巴特拉姆(Bartram)圆翅蝈蝈Amblycorypha bartrami (tetigoniae, Phaneropterinae)鸣叫歌声的变异和遗传学揭示了新物种

Previous work on Bartram’s round-winged katydid, Amblycorypha bartrami Walker, found inconsistencies in song variation across the species’ range. Individuals of purported populations of A. bartrami from sandhills across the southeastern US were collected, recorded, and their genes were sequenced to better understand their population structure and evolution. Significant differences in songs, morphology, and genetics were found among populations from Alabama (AL), Georgia (GA), North Carolina (NC), and South Carolina (SC), and they differed from those of individuals collected from the type locality in Florida (FL). Males from all populations produced songs composed of a series of similar syllables, but they differed in the rates at which syllables were produced as a function of temperature. At temperatures of 25°C, the calling songs of males from populations in northern AL and GA were found to have the highest syllable rates, those from SC had the lowest rates, and those from NC were found to produce songs with doublet syllables at rates that were intermediate between those of males from FL and those of AL and GA. These song differences formed the basis for cluster analyses and principal component analyses, which showed significant clustering and differences in song spectra and morphology among the song morphs. A Bayesian multi-locus, multi-species coalescent analysis found significant divergences from a panmictic population for the song morphs. Populations from GA and AL are closely related to those of A. bartrami in FL, whereas populations from NC and SC are closely related to each other and differ from the other three. Large river systems may have been important in isolating these populations of flightless katydids. Based on the results of our analyses of songs, morphology, and genetics, three new species of round-winged katydids from the southeastern coastal plain and piedmont are described.
之前对巴特拉姆的圆翅蝈蝈(Amblycorypha bartrami Walker)的研究发现,不同种类蝈蝈叫声的变化并不一致。在美国东南部的沙丘上收集并记录了疑似bartrami种群的个体,并对其基因进行了测序,以更好地了解其种群结构和进化。阿拉巴马州(AL)、乔治亚州(GA)、北卡罗来纳州(NC)和南卡罗来纳州(SC)的种群在鸣叫、形态和遗传学上存在显著差异,与佛罗里达州(FL)的种群不同。所有种群的雄性都能发出由一系列相似音节组成的歌曲,但它们发出音节的速度随着温度的变化而不同。在25°C的温度下,来自北部AL和GA种群的雄性鸣叫的音节率最高,来自SC的雄性鸣叫的音节率最低,而来自NC的雄性鸣叫的双音节率介于FL和AL和GA之间。这些鸣声差异构成了聚类分析和主成分分析的基础,显示出不同鸣声变体在鸣声谱和形态上的显著聚类和差异。一项贝叶斯多位点、多物种聚结分析发现,在一个泛型种群中,歌型有显著的差异。GA和AL的居群与FL的bartrami居群亲缘关系密切,NC和SC的居群亲缘关系密切,且与其他3个居群存在差异。大型河流系统可能对隔离这些不会飞的蝈蝈种群很重要。根据鸣叫、形态学和遗传学分析的结果,描述了东南沿海平原和山前地区圆翅蝈蝈的3个新种。

Alien mantids in a tropical paradise: First record of the giant mantis Sphodromantis viridis (Insecta, Mantodea) for the Canary Islands (Spain) Alien热带天堂中的螳螂:西班牙加那利群岛首次发现巨型螳螂Sphodromantis viridis(昆虫亚目,螳螂亚目)

The presence of adults, nymphs, and oothecae of the African giant mantis Sphodromantis viridis Forsskål is for the first time recorded on the island of Tenerife, the largest and most populated of the Canary archipelago, an autonomous Spanish community in the Atlantic Ocean. The discovery took place in a popular water park rich in non-native plants in the municipality of Costa Adeje. It is possible that anthropogenic movements, particularly the massive movement of tourists and goods that continually cross this small archipelago, aided the dispersal to the area of this mantis, which for some years has also been expanding in many areas of the Mediterranean basin. A hypothesis on the ecological impact and the possible invasiveness of this extremely adaptable species is discussed and supported by the large number of sightings of oothecae and specimens that are, fortunately, still confined within the west coast of the island.
非洲巨型螳螂Sphodromantis viridis Forsskål的成虫、若虫和卵鞘首次在特内里费岛上被记录到,该岛是大西洋上一个自治的西班牙社区加那利群岛中最大、人口最多的岛屿。这一发现发生在Costa Adeje市一个盛产非本土植物的热门水上公园。人类活动,特别是不断穿越这个小群岛的游客和货物的大规模流动,有可能有助于这种螳螂向该地区的扩散,多年来,这种区域也在地中海盆地的许多地区扩张。关于这种适应性极强的物种的生态影响和可能的入侵性的假设得到了讨论,并得到了大量卵鞘科和标本的支持,幸运的是,这些卵鞘和标本仍局限在该岛西海岸。
