Abstract. Peach silver mite, Aculus fockeui (Acari: Prostigmata) is one of the most damaging pests of plum and peach trees. A study was conducted to determine the population dynamics A. fockeui (Nalepa and Trouessart, 1890) (Acari: Eriophyidae) in pesticide-free plum and peach orchards in three different localities (Termal, Çınarcık, and Centrum) of the Yalova Province in Turkey during 2018–2019. Aculus fockeui were found on leaves throughout the vegetative period in both plum (Prunus domestica) and peach (P. persica) orchards, and populations reached their densities between June and August in both years. Temperature and host plant differences had a significant effect on the population density, which was significantly higher in plum orchards than peach orchards. The predators Zetzellia mali (Ewing) (Acari: Stigmaeidae) and Phytoseiulus persimilis Athias-Henriot (Acari: Phytoseiidae) were observed feeding on eriophyid mites in all orchards sampled. Further studies are needed to investigate their predation rate, effectiveness and potential as biological control agents for eriophyid mites.
摘要桃银螨(Aculus fockeui,Acari: Prostigmata)是危害李树和桃树最严重的害虫之一。2018-2019年期间,研究人员在土耳其亚洛瓦省三个不同地区(Termal、Çınarcık和Centrum)的无农药李子和桃园中确定了A. fockeui (Nalepa and Trouessart, 1890) (Acari: Eriophyidae)的种群动态。在李子(Prunus domestica)和桃子(P. persica)果园的整个无性繁殖期间,叶片上都发现了Aculus fockeui,种群密度在这两年的6月至8月间达到最高。温度和寄主植物的差异对种群密度有显著影响,李子园的种群密度明显高于桃园。在所有取样的果园中都观察到天敌 Zetzellia mali (Ewing)(Acari: Stigmaeidae)和 Phytoseiulus persimilis Athias-Henriot(Acari: Phytoseiidae)以麦穗螨为食。需要进一步研究它们的捕食率、效果和作为麦穗螨生物控制剂的潜力。

Abstract. Although the generic name implies that the genus Malayaxenos Kifune is from Southeast Asia, the current distribution is more cosmopolitan. Species are now known from Germany, United States of America, Dominica, Colombia, Australia, and Malaysia. As part of this distribution, four new species are named: Malayaxenos baileyi new species, Malayaxenos dominicensis new species, Malayaxenos kogani new species, and Malayaxenos platycephala new species. Additionally, Australoxenos Kathirithamby is proposed here as a junior synonym of Malayaxenos, making its only species Malayaxenos yetmaniensis new combination. All species in Malayaxenos are herein described or reviewed and a world key is provided for species identification.

Abstract. The genitalia of an unusually pale and uniform male of Gesta (Erynnides) from central Texas are intermediate between those of Gesta horatius and Gesta tristis tatius, owing to interspecific hybridization. These sister species are widely distributed (mainly from the eastern United States and from the southwestern United States to Colombia, respectively) and barely sympatric. Four different methods of analyzing data from whole genome sequencing of 7 specimens of each parental species, 6 specimens of related species G. meridianus (as an outgroup), and the specimen with the peculiar genitalia show that it is an F1 hybrid whose mother is G. t. tatius. The superficial appearance of this hybrid does not suggest either parent.

Newly Documented Life History of Tenthredo mellicoxa Provancher (Hymenoptera: Tenthredinidae) from Hydrophyllum virginianum L. (Boraginaceae) 原产于水草科(水草科)的绒螯蛛生活史新记录(膜翅目:绒螯蛛科)

the most species-rich genus of Symphyta (sawflies) with more than 1000 described species worldwide—roughly 154 of these found in the Nearctic Region (Taeger et al. 2018, Goulet 2020). Despite their larger body size relative to many sawflies, surprisingly little is known of the biology of this genus in North America—we estimate the life histories of greater than 90 percent remain unknown (Baine et al. 2019). Published host records are documented from a wide diversity of plant families, and while several species appear to be highly specialized, many Palearctic Tenthredo are considered to be mainly polyphagous (Goulet 1996). Herein, we reveal for the first time the life history of T. mellicoxa Provancher, 1878 (Fig. 2) from Virginia waterleaf (Hydrophyllum virginianum L.) (Boraginaceae). As the first member of the T. rufopectus species group with a known life history, we hope this discovery will offer clues to the biology of related Tenthredo species, i.e., T. rufopectus (Norton, 1860), T. nimbipennis Cresson, 1872, T. ruma MacGillivray, 1923, and T. fernowi Goulet and Smith, 1995. As T. mellicoxa appears to be a Hydrophyllum specialist, we predict its kin may also be dietary specialists. In late April 2022, in Brown Co., Kansas (Hamlin, No-man’s Land Farm, (39.90625° lat, -95.58656° long)), TAM observed an abundance of adult T. mellicoxa flying around a large stand of Virginia waterleaf in a mesic, mixed deciduous forest (Fig. 1). Where the adults were abundant, Hydrophyllum, just shy of blooming, stood about 0.5 m tall and was the dominant understory plant. Adult Tenthredo (Fig. 2) were readily collected with a sweep net as they skimmed low above the waterleaf or as they perched on the upper surface of waterleaf leaves. TAM netted four adult females and placed them into separate 50-dram vials, each bearing a single Hydrophyllum leaf. All four females successfully oviposited. Observed details of the life history are as follows. Ova were inserted between the lower epidermis and mesophyll in nonvascular areas of the waterleaf leaf tissue (Fig. 3). The captive oviposition rate was remarkably consistent across the four captured females; each laid 12–15 eggs, with oviposition slowing 48 hours post collection and ceasing altogether 72 hours post collection. Eggs hatched 9–10 days post oviposition and first instar larvae immediately began feeding solitarily within the interior of the leaf blade leaving ovate holes behind (Fig. 4). The cloudy white bloom of early instars was replaced by the characteristic gray dorsum of later instars in the third instar. Like other Tenthredo and related genera, when not actively feeding larvae often coiled themselves on the undersides of the leaves, and when disturbed, would drop from the leaf surface.

Symphyta属(锯蝇)是物种最丰富的属,在全球范围内有1000多个物种,其中大约154个在近北地区发现(Taeger等人,2018,Goulet 2020)。尽管相对于许多锯蝇来说,它们的体型更大,但令人惊讶的是,人们对北美该属的生物学知之甚少——我们估计,90%以上的人的生活史仍然未知(Baine等人,2019)。已发表的寄主记录来自广泛多样的植物科,虽然有几个物种似乎是高度特化的,但许多古北极帐篷被认为主要是多食性的(Goulet 1996)。在此,我们首次揭示了T.mellicoxa Provancher的生活史,1878年(图2),来自弗吉尼亚睡莲(Hydrophyllum virginianum L.)(紫草科)。作为第一个有已知生活史的T.rufopectus物种群成员,我们希望这一发现能为相关Tentredo物种的生物学提供线索,即T.rufospectus(Norton,1860)、T.nimbipennis Cresson,1872、T.ruma MacGillivray,1923以及T.fernowi Goulet和Smith,1995。由于T.mellicoxa似乎是水生植物专家,我们预测它的亲属也可能是饮食专家。2022年4月下旬,在堪萨斯州布朗公司(哈姆林,无人区农场,(39.90625°纬度,-95.558656°长),TAM观察到大量的成年甜叶T.mellicoxa在一片混合落叶林中的弗吉尼亚州大片睡叶周围飞行(图1)。在成虫丰富的地方,水生植物几乎没有开花,高约0.5米,是林下的主要植物。成年Tentredo(图2)在吃水线以上低空掠过或栖息在吃水线叶片上表面时,很容易用清扫网收集。TAM捕获了四只成年雌性,并将它们分别放入50德拉姆的小瓶中,每个小瓶上都有一片水生植物叶子。四只雌性都成功产卵。观察到的生活史细节如下。卵被插入在无水叶叶组织的无血管区域的下表皮和叶肉之间(图3)。四只被捕获的雌性的圈养产卵率非常一致;每只产卵12-15枚,产卵速度在采集后48小时减慢,采集后72小时停止。产卵后9-10天孵化的卵,一龄幼虫立即开始在叶片内部单独进食,留下卵孔(图4)。初龄的云白色花朵在三龄时被晚龄的特征性灰背所取代。与其他Tentredo属和相关属一样,当幼虫不积极进食时,它们经常盘绕在叶子的下侧,当受到干扰时,它们会从叶子表面掉下来。第五龄,即蛹前龄,并没有形成蚕茧,而是被发现躲在土细胞中,可能会越冬,直到化蛹,然后在第二年春天羽化。从产卵到预产卵的平均时间为21天。对蜜桃未成熟阶段的描述如下:Ova PROC。昆虫学。SOC。WASH.124(4),2022,第884-888页

Despite their larger body size relative to many sawflies, surprisingly little is known of the biology of this genus in North America—we estimate the life histories of greater than 90 percent remain unknown (Baine et al. 2019). Published host records are documented from a wide diversity of plant families, and while several species appear to be highly specialized, many Palearctic Tenthredo are considered to be mainly polyphagous (Goulet 1996). Herein, we reveal for the first time the life history of T. mellicoxa Provancher, 1878 (Fig. 2) from Virginia waterleaf (Hydrophyllum virginianum L.) (Boraginaceae). As the first member of the T. rufopectus species group with a known life history, we hope this discovery will offer clues to the biology of related Tenthredo species, i.e., T. rufopectus (Norton, 1860), T. nimbipennis Cresson, 1872, T. ruma MacGillivray, 1923, and T. fernowi Goulet and Smith, 1995. As T. mellicoxa appears to be a Hydrophyllum specialist, we predict its kin may also be dietary specialists. In late April 2022, in Brown Co., Kansas (Hamlin, No-man’s Land Farm, (39.90625° lat, -95.58656° long)), TAM observed an abundance of adult T. mellicoxa flying around a large stand of Virginia waterleaf in a mesic, mixed deciduous forest (Fig. 1). Where the adults were abundant, Hydrophyllum, just shy of blooming, stood about 0.5 m tall and was the dominant understory plant. Adult Tenthredo (Fig. 2) were readily collected with a sweep net as they skimmed low above the waterleaf or as they perched on the upper surface of waterleaf leaves. TAM netted four adult females and placed them into separate 50-dram vials, each bearing a single Hydrophyllum leaf. All four females successfully oviposited. Observed details of the life history are as follows. Ova were inserted between the lower epidermis and mesophyll in nonvascular areas of the waterleaf leaf tissue (Fig. 3). The captive oviposition rate was remarkably consistent across the four captured females; each laid 12–15 eggs, with oviposition slowing 48 hours post collection and ceasing altogether 72 hours post collection. Eggs hatched 9–10 days post oviposition and first instar larvae immediately began feeding solitarily within the interior of the leaf blade leaving ovate holes behind (Fig. 4). The cloudy white bloom of early instars was replaced by the characteristic gray dorsum of later instars in the third instar. Like other Tenthredo and related genera, when not actively feeding larvae often coiled themselves on the undersides of the leaves, and when disturbed, would drop from the leaf surface. The fifth, prepupal instar did not form a silken cocoon, but rather was found to shelter in an earthen cell, presumably overwintering until pupation and subsequent eclosion the following spring.

Abstract. No comprehensive identification resource is available for the genus Frankliniella. In response, a dynamic internet–based platform with interactive identification tools, species fact sheets and slide preparation tutorials are being developed by the author(s). We reviewed certain type, port interceptions, and origin collected specimens. We attempted to validate species identification using non-destructive DNA extraction and sequencing of both intercepted and field collected specimens. Sequences explicitly linked to a permanently curated morphological voucher specimen were deposited in a public repository (GenBank). The morphological review and genetic analysis revealed that both F. bruneri Watson and F. xanthaner Hood are each likely cryptic species complexes. Five species are described, F. ecuatoriana new species, F. funderburki new species, F. pelucensis new species, F. sanabriana new species and F. suramericana new species. Sequence data are recorded for the holotype specimens of the latter four species. Taxonomic status changes for F. genuina Hood and F. venusta Moulton are provided.
摘要Frankliniella属无综合鉴定资源。作为回应,作者正在开发一个基于互联网的动态平台,其中包括交互式识别工具、物种概况介绍和幻灯片制作教程。我们审查了某些类型、港口拦截和来源采集的标本。我们试图通过对截获和现场采集的标本进行无损DNA提取和测序来验证物种鉴定。与永久策划的形态学凭证样本明确链接的序列被存放在公共存储库(GenBank)中。形态学研究和遗传分析表明,布鲁内里·沃森和黄原胶胡德都可能是隐蔽的物种复合体。描述了五个物种,即欧洲F.ecuatoriana新种、芬德伯克F.funderburki新种、佩卢西斯F.pelucensis新种、桑纳布里亚F.sanabriana新种和南美F.suramericana新种。记录了后四个物种的正模标本的序列数据。文中提供了genuina Hood和venusta Moulton的分类状态变化。
