The orthopteroid insects described by Linnaeus,with notes on the Linnaean collection

A list is given of the recently recurated Orthoptera s.l. held by the Linnean Society of London. The status of specimens in the collection is evaluated, eight lectotype designations are made, and the orthopteroid species described by Linnaeus are listed alphabetically.     

The Noctuoidea (Lepidoptera) described by Linnaeus

Linnaeus described 166 nominal species of Noctuoidea, of which 144 (86.7%) are currently used as valid names, 18 are synonyms, one is a homonym and three taxa remain unknown. Seven taxa were described solely from illustrations in contemporary literature. Lectotypes are designated for 139 (87.4%) of the 159 remaining taxa, 122 of them from the Linnaean collection in London, 13 from the Queen Ludovica Ulrica's collection in Uppsala, Sweden, and four from other contemporary collections. Two Linnaean senior synonyms are introduced: Hada plebeja comb. nov. (Linnaeus, 1761) for the current H. nana (Hufnagel, 1766) and Oeonistis altica (Linnaeus, 1768) comb. nov. for Oe. entella (Cramer, 1779). Erebus occiduus (Linnaeus, 1758) syn. nov. is a junior subjective synonym of E. crepuscularis (Linnaeus, 1758); L. marmorides (Cramer, 1775) Stat. rev. should be reinstated for Letis occidua auct. In two species pairs the Linnaean names have been interpreted incorrectly. The lectotype designation of Phalaena prasinana Linnaeus, 1758, by Lempke (1947) is invalid because the specimen is not syntypic. According to the new lectotype, Pseudoips prasinanus (Linnaeus, 1758) comb. nov. replaces P. faganus (Fabricius, 1781), and Bena bicolorana (Fuessly, 1775) comb. nov. is available for the other species. Abrostola triplasia (Linnaeus, 1758) Stat. rev. replaces A. trigemina (Werneburg, 1864), and for the other species A. triparlila (Hufnagel, 1766) should be reinstated. One neotype designation [Eilema complanum (Linnaeus, 1758)], one lectotype designation [Xylena exsolela (Linnaeus, 1758)], and precedence of a junior synonym [Ophideres fullonia (Clerck, 1764)] over its unused senior synonym are to be referred to the ICZN; until their decision the current usage must be followed. The identity of Mesapamea secalis (Linnaeus, 1758) stat. rev. corresponds to current usage, but, under presence of syntypic material, the recent neotype designation by Lempke (1988) will be referred to the ICZN. The revision is mainly based on the discovery that the insect pins and the way specimens are prepared give evidence of the authenticity of the material. Contrary to the views of earlier authors, Linnaeus had his labels with the specific name pinned against the bottom of the drawers by the specimen pin. Because the labels have been moved twice during subsequent curations, their present position is less indicative of the authenticity than has been previously suggested. The origin of the so-called n-labels is discussed.     

Re-curation of the Linnaean Hymenoptera (Insecta), with a reassessment of the taxonomic importance of the collection

The history of acquisition and maintenance of the Linnaean insect collections is briefly summarized. Curatorial details (such as kinds of label) are discussed, chiefly with reference to Hymenoptera. Some misleading opinions concerning the taxonomic value of the collections and the nature of Linnaean type-material are examined and a practical approach is recommended. The rationale governing re-curation of the collections is detailed, and the present contents of the collection of Hymenoptera are listed in order to inform interested specialists.     

Discovery in the Linnaean collection of type-material of insects described by Johann Reinhold Forster, with notes on the Hymenoptera

Type-material of 100 insect species described by J. R. Forster has always been thought lost. We present evidence that syntypic specimens of some of these species were sent by Forster to Linnaeus in 1772. Specimens of at least 27 species survive in the Linnaean collection now in Burlington House, and are listed. The identity of each of the 18 species of Hymenoptera described by Forster is examined in detail, particularly the nine represented by specimens. Lectotypes are designated for two species; four new synonymies and two new combinations are established; and three names remain nomina dubia within their genera.     

The species of Hymenoptera described by Linnaeus in the genera Sphex, Chrysis, Vespa, Apis and Mutilla

Data are presented on the type-material representing the species described by Linnaeus in his genera Sphex, Chrysis, Vespa, Apis and Mutilla , The names here considered total 158; six are currently applied in the Hymenoptera Parasitica. Of the balance of 147, three are emendations and five are unavailable homonyms or names proposed in the synonymy of other species. Fifteen Linnaean names are here placed as synonyms. One name is attributed to an author other than Linnaeus, and live names remain species incertae sedis. The remainder, 118, are applied as valid names in die Hymenoptera Aculeata. Holotype specimens in London, Uppsala or Stockholm represent 60 names; 55 names are based on lectotype specimens of which 49 are here designated, two by other authors. One name is represented by a neotype specimen in Lund, and one by a lectotype figure. One non-aculeate species is based on syntypes. Specimens appear to be lost with respect to 25 names; three specimens in Uppsala may be the holotypes of a further three species.
Eight new combinations are made, and twelve new synonyms established; three further new combinations and three further new synonymies are suggested. A systematically arranged summary of species treated and of nomenclatural changes made is given. Nomenclatural changes affecting non-Linnaean names are included where relevant; lectotypes are designated for two non-Linnaean species.     

The Linnaean fish collection in the Zoological Museum of the University of Uppsala

Specimens of fishes preserved in the Zoological Museum, University of Uppsala, which are believed to have been examined by Linnaeus, are listed. Most of these were originally given to the University in several donations by benefactors of the Academy and were described by Linnaeus in dissertations defended by students. Some specimens, however, are believed to have originated from Linnaeus's own collection. Many of the specimens have type status and this is discussed together with notes on other surviving Linnaean fish specimens.     

The species of "Ichneumon" (Hymenoptera) described by Linnaeus

Ichneumonidae in the Linnaean and other collections have been critically assessed with regard to their status as type-specimens of species described by Linnaeus. The generic placements of the 56 nominal species of Ichneumonidae (54 originally in Ichneumon and two in Mutilla) described by Linnaeus are established after study of the extant type-material. Lectotypes are designated for eleven of the species and one new synonymy is established. Notes are given on the 33 species originally described by Linnaeus in Ichneumon but now placed in other families.     

The Linnaean fish collection in the Linnean Society of London

Linnaeus's personal collection of fishes was part of the material purchased by J. E. Smith in 1783–1784 from Linnaeus's widow and which became the property of the Linnean Society of London in 1828. There are extant 168 dried specimens of fishes, mostly skins mounted on paper in the manner of herbarium specimens. The spirit-preserved material which belonged to Linnaeus was never sent from Sweden.
The history of the collection is recounted, and the sources of the specimens discussed. A catalogue of the collection is presented with discussion of the type status of the specimens and the sources for the typification of each taxon.     

The Evolution of the Linnaean Hierarchy

The Linnaean system of classification is a threefold system of theoretical assumptions, sorting rules, and rules of nomenclature. Over time, that system has lost its theoretical assumptions as well as its sorting rules. Cladistic revisions have left it less and less Linnaean. And what remains of the system is flawed on pragmatic grounds. Taking all of this into account, it is time to consider alternative systems of classification.     

The Linnaean Species of the Families Fanniidae, Anthomyiidae and Muscidae (Insecta: Diptera)

Linnaeus described eleven species in the genera Musca and Conops that are now placed in the Fanniidae, Anthomyiidae and Muscidae. A study is presented of the types and other material of these three families in his collection.     

Taxonomy of gastropods of the families Ranellidae (= Cymatiidae) and Bursidae. Part 2. Descriptions of 14 new modern Indo-West Pacific species and subspecies,with revisions of related taxa

Abstract

The subgenus Cymatium (Septa) is here restricted to species closely related to C. rubeculum (Linné, 1758). A lectotype is designated for C. rubeculum, neotypes are designated for C. hepaticum (Röding, 1798) and C. flaveolum (Röding, 1798), C. occidentale (Mörch, 1877) (= blacketi Iredale, 1936; = beui Garcia-Talavera, 1985) is recorded from the Indo-West Pacific, C. (Septa) marerubrum Garcia-Talavera, 1985 is ranked as a geographic subspecies of C. rubeculum, and three new taxa are named: C. (Septa) bibbeyi n. sp., Philippine Islands; C. (Septa) closeli n. sp., Indian Ocean; and C. (Septa) peasei n. sp., western Pacific. In the subgenus Cymatium (Ranularia), neotypes are designated for C. guttumium (Röding, 1798) and its synonyms, for C. moniliferum (A. Adams & Reeve, 1850), and for C. pyrulum (A. Adams & Reeve, 1850), a lectotype is designated for C. pseudopyrum (Martin, 1899) (a junior synonym of C. pyrulum), other species distinguished are C. encausticum (Reeve, 1844) and C. exile (Reeve, 1844), and new taxa named are C. andamanense n. sp., Andaman Islands, C. springsteeni n. sp., western Pacific and Red Sea, and C. sinense arthuri n. subsp., Red Sea. Other Ranellidae named are Sassia (Sassia) ponderi n. sp., Queensland, and Distorsio (Distorsio) euconstricta n. sp., Indian Ocean and southwest Pacific. A lectotype selected for Murex reticularis Linné, 1758 is a specimen of the species usually known as Distorsio reticulata (Röding, 1798).

In Bursa (Bursa), a lectotype is designated for B. grayana Dunker, 1862 (= B. bufoniopsis Maury, 1917; = B. pacamoni Matthews & Coelho, 1971), western Atlantic, and the similar new Oman to Philippines species B. davidboschi is named. Other Bursa taxa named are B. (Colubrellina) quirihorai n. sp., Philippines, and B. (Colubrellina) latitudo fosteri n. subsp., Philippines. In Bufonaria (Bufonaria), a lectotype designated for Murex rana Linné, 1758 confirms that as the name for the most common western Pacific species, a lectotype designated for Ranella crumena Lamarck, 1816 confirms that as the name for the most common Indian Ocean species, B. elegans (Beck in G. B. Sowerby II, 1836) is illustrated, and the new western Pacific species B. perelegans is named; the four similar species B. nobilis (Reeve, 1844), B. margaritula (Deshayes, 1832), B. gnorima (Melville, 1918), and B. thersites (Redfield, 1846) are distinguished, and the new Madagascar to Philippines species B. ignobilis is named. In Tutufa (Tutufella), the newly named species T. boholica occurs with T. rubeta (Linné, 1758) in deep water in the Philippine Islands.

滞育昆虫营养物质的积累、转化与调控

滞育是昆虫度过不良环境的一种生存适应策略,营养物质的利用、积累和转化影响昆虫的滞育。滞育期间,昆虫体内发生一系列生理生化变化,包括脂类、碳水化合物和氨基酸等内源营养物质呈特异性地积累或转化,保障了滞育个体在逆境中存活及滞育解除后发育的能量需求。外源营养物质对昆虫滞育的影响较复杂,其种类、丰度、质量能通过"食料-寄主-天敌"营养关系进行传递,影响昆虫体内营养物质的积累和转化,改变昆虫的耐寒性、滞育率等,制约昆虫的滞育深度、滞育存活率。滞育昆虫营养物质积累、利用机制复杂多样,胰岛素信号通路-叉头转录因子以及激脂激素的调控效应在滞育诱导及营养物质转化中起到了关键的调控作用,但滞育的系统性调控仍需进一步深入研究。     

Fenoxycarb, a fairly new Insect Growth Regulato: review of its effects on insects

To reduce the impact of pesticides, new more selective chemicals need to be developed. Insect Growth Regulators such as Juvenile Hormone Analogues seem promising because of their specific mode of action on insects and their lower toxicity against Vertebrates than conventional insecticides. Nevertheless they remain toxic compounds. Fenoxycarb, a non neurotoxic carbamate shows a high JH activity, but also has other non JH specific effects. Effects of fenoxycarb on different pest and non-target insects were reviewed from nearly 200 scientific papers dealing with this chemical used as insecticide.     

苹果蠹蛾的综合防控和遗传控制研究进展

苹果蠹蛾是仁果类水果的重要检疫害虫,在世界各地造成了巨大的经济损失。目前对其化学防治、化学生态调控、病毒等防治方法研究较多,但仍不能满足防控该害虫的需要,对新型防控技术的需求日益增强。不育昆虫释放技术(SIT)是一种可控制甚至根除靶标害虫的环境友好型防控技术,但传统SIT技术存在一定的局限性,如较难区分性别与筛选雌雄虫、辐射不育昆虫的交配竞争力和适合度降低等问题,这些缺陷随着昆虫遗传修饰技术的发展将得以解决,并将在害虫防控进程中起到积极作用。本文综述了苹果蠹蛾主要防控技术研究现状,介绍了通过遗传修饰技术改善SIT的技术策略,并综合分析了我国开展苹果蠹蛾遗传修饰研究情况和将其应用在苹果蠹蛾防控体系中的可行性及优势。     

Effects of habitat fragmentation on the functional diversity of insects in Thousand Island Lake,China

Due to habitat fragmentation, the loss of species diversity has been extensively studied. On the contrary, the effects of habitat fragmentation on functional diversity is still poorly understood. In the Thousand Island Lake, we conducted studies of insect functional diversity on a set of 29 isolated islands. We used 10 functional diversity indices from three aspects (functional richness, functional evenness and functional divergence) to respectively describe functional diversity of insects on sample islands. We found the following results: (i) The functional indices selected could reflect the functional diversity of sample islands and it is further proved that in general, three components of functional diversity were independent of each other; (ii) Sample islands could be divided into two categories, island JSD and the remaining islands; (iii) Functional richness increased with island area and shape index, but had no significant correlation with isolation. Likewise, both functional evenness and functional divergence had no significant correlation with island attributes. The conclusion to emphasize from our research is that: (i) habitat fragmentation reduced the biological functional diversity to some extent, further demonstrating the importance of habitat continuity in biodiversity protection; and (ii) for functional diversity protection of insects in a fragmented landscape, an island which has high approximate shape index values of at least hundred hectare magnitude order has a critical promoting effect.
