Indeed, it was a ladybird (the Vedalia beetle, Rodolia cardinalis, introduced from Australia to California to control cottony cushion scale, Icerya purchasi, in citrus plantations) that is thought to mark the advent of modern biological control. Classical biological control success stories are undoubtedly numerous and there are very few examples where problems have occurred. Harmonia axyridis is, however, one such species. This species was introduced intentionally to a number of countries as a biological control agent of pest insects. Although H. axyridis is a success in terms of contributing to the reduction of pest numbers to below economic thresholds, it is considered both a human nuisance in the autumn, as it occupies premises in high numbers, and also a threat to native biodiversity through competition and predation. This species has spread rapidly across northern and central Europe and is now found at high abundance in many countries. Harmonia axyridis has now been recorded as established in (order relates to approximate time of establishment): France (first report), Germany, Belgium, Netherlands, Switzerland, Luxembourg, England, Czech Republic, Italy, Austria, Denmark, Norway, Poland, Wales, Liechtenstein, Scotland, Hungary, Slovakia and Bulgaria (last report). Research to quantify the extent of any negative effects is essential, and collaborative effort is necessary to further understanding of this conspicuous invader. In recognition of this, the IOBC/WPRS (International Organization for Biological Control/ Western Palaearctic Regional Section) Study Group “Benefits and Risks of Exotic Biological Control Agents” was established to encourage collaborations on this species and other exotic biological control agents. This study group is not only a forum for those with an interest in biological control but also offers an opportunity to contribute to understanding of invasive species ecology. The movement of species around the globe has been occurring at a staggering rate in recent decades. Many non-native species are considered to be exquisite additions in their new locality but approximately one percent of new arrivals are considered to pose an unacceptable risk to biodiversity and termed “invasive non-native (=alien) species”. Harmonia axyridis is widely accepted to be an invasive non-native species and as such provides a model system for invasion biologists. The first dedicated meeting of this Study Group was held in the beautiful location of Engelberg, Switzerland in September 2009. This four day meeting was a unique opportunity for scientists to gather, share their findings, predictions and future directions on this species and other invasive non-native ladybirds. The collaborative spirit of this IOBC/WPRS Study Group ensures an excellent forum for unravelling the dynamics of Harmonia axyridis and other exotic biological control agents.

EENY-170 Ladybirds, Ladybird beetles, Lady Beetles, Ladybugs of Florida, Coleoptera: Coccinellidae1 J. H. Frank R. F. Mizell, III2 Introduction Ladybird is a name that has been used in England for more than 600 years for the European beetle Coccinella septempunctata. As knowledge about insects increased, the name became extended to all its relatives, members of the beetle family Coccinellidae. Of course these insects are not birds, but butterflies are not flies, nor are dragonflies, stoneflies, mayflies, and fireflies, which all are true common names in folklore, not invented names. The lady for whom they were named was "the Virgin Mary," and common names in other European languages have the same association (the German name Marienkafer translates Figure 1. Adult Coccinella septempunctata Linnaeus, the to "Marybeetle" or ladybeetle). Prose and poetry sevenspotted lady beetle.

Coccinella septempunctata. We can but hope that newspaper writers will desist from generalizing them In the USA, the name ladybird was popularly all as "the ladybird" and thus deluding the public into americanized to ladybug, although these insects are believing that there is only one species. There are beetles (Coleoptera), not bugs (Hemiptera). many species of ladybirds, just as there are of birds, and the word "variety" (frequently use by newspaper 1.

Entomol. 40(6): 1541Ð1545 (2011); DOI: http://dx.doi.org/10.1603/EN10240 Downloaded from https://academic.oup.com/ee/article/40/6/1541/532414 by guest on 23 September 2021 ABSTRACT Thermal requirements (lower temperature threshold and thermal constant) for the development of each developmental stage of the predator Harmonia axyridis (Pallas) were studied on Aphis fabae Scopoli and Dysaphis crataegi (Kaltenbach) under controlled laboratory conditions. The effect of temperature (15, 20, 25, and 30ЊC) and prey species was examined on pre-imaginal developmental duration and life cycle (pre-oviposition period included) of the predator. Our results suggest comparable thermal requirements for the development of H. axyridis on the particular prey and when compared with other aphid species. The total preimaginal development of H. axyridis,at 15, 20, and 30ЊC, and its life cycle, at 15 and 30ЊC, are shorter on D. crataegi than on A. fabae.

We studied parasites of 16 the global invader Harmonia axyridis (Coleoptera: Coccinellidae) in the Caucasus. In 2012 the first 17 established population of H. axyridis was recorded in the Caucasus in Sochi (south of European Russia, 18 Black sea coast). By 2018 the ladybird has spread to the vast territory: Armenia, Georgia and south 19 Russia: Adygea, Krasnodar territory, Stavropol territory, Dagestan, Kabardino-Balkaria and North 20 Ossetia. Examination of 213 adults collected in Sochi in 2018 have shown that 53% of them are infested 21 with Hesperomyces virescens fungi (Ascomycota: Laboulbeniales) and 8% with Parasitylenchus 22 bifurcatus nematodes (Nematoda: Tylenchida, Allantonematidae).

Its biology and life table were studied in nymph/adult hosts of Aphis gossypii Glover, Aphis fabae Scop. and on the eggs of Ephestia kuehniella Zeller. Raw data of all individuals of A. decempunctata were analyzed using the age-stage, two-sex, life-table theory. The results of this study indicate a shortest immature developmental period (IDP) of A. decempunctata feeding on eggs of E. kuehniella (18.33 days) and the longest on A. fabae (21.82 days). The longest longevity was, however, after feeding on A. gossypii. The fecundity rate of females on E. kuehniella was the highest (2405.12 eggs/female). The intrinsic rates of increase of A.

Hoffmann1,2, J. Pawłowska3, G. Walther1,2,4, M. Wrzosek3, G.S. de Hoog4, G.L. Benny5*, P.M. Kirk6*, K. Voigt1,2* Key words Abstract The Mucorales (Mucoromycotina) are one of the most ancient groups of fungi comprising ubiquitous, mostly saprotrophic organisms. The first comprehensive molecular studies 11 yr ago revealed the traditional Mucorales classification scheme, mainly based on morphology, as highly artificial. Since then only single clades have been families investigated in detail but a robust classification of the higher levels based on DNA data has not been published phylogeny yet. Therefore we provide a classification based on a phylogenetic analysis of four molecular markers including the large and the small subunit of the ribosomal DNA, the partial actin gene and the partial gene for the translation elongation factor 1-alpha. The dataset comprises 201 isolates in 103 species and represents about one half of the currently accepted species in this order. Previous family concepts are reviewed and the family structure inferred from the multilocus phylogeny is introduced and discussed. Main differences between the current classification and preceding concepts affects the existing families Lichtheimiaceae and Cunninghamellaceae, as well as the genera Backusella and Lentamyces which recently obtained the status of families along with the Rhizopodaceae comprising Rhizopus, Sporodiniella and Syzygites. Compensatory base change analyses in the Lichtheimiaceae confirmed the lower level classification of Lichtheimia and Rhizomucor while genera such as Circinella or Syncephalastrum completely lacked compensatory base changes.

  • Testing the Applicability of Regional IUCN Red List Criteria on Ladybirds (Coleoptera, Coccinellidae) in Flanders (North Belgium): Opportunities for Conservation
    Insect Conservation and Diversity (2015) doi: 10.1111/icad.12124 MINOR REVIEW Testing the applicability of regional IUCN Red List criteria on ladybirds (Coleoptera, Coccinellidae) in Flanders (north Belgium): opportunities for conservation TIM ADRIAENS,1 GILLES SAN MARTIN Y GOMEZ,2 JOHAN BOGAERT,3 LUC CREVECOEUR,4 JEAN-PIERRE BEUCKX5 and 1 DIRK MAES 1Research Institute for Nature and Forest (INBO), Brussels, Belgium, 2Behavioural Ecology and Conservation Group, Biodiversity Research Centre, Earth and Life Institute, Universite catholique de Louvain (UCL), Louvain-la-Neuve, Belgium, 3Belgian Ladybird Working Group, Kessel-Lo, Belgium, 4LIKONA, Genk, Belgium and 5Heers, Belgium Abstract. 1. Red Lists assess the extinction risk of species and are an impor- tant tool to prioritise species conservation and management measures. World- wide, quantitative IUCN criteria are used to estimate the threat status of species at the regional level. 2. In Flanders (north Belgium), about 70 000 distribution records of lady- birds were collected in 36% of all the grid cells (1 9 1km2) since 1990 during a large-scale citizen-science project. 3. Applying the IUCN criteria to the 36 resident ‘conspicuous’ ladybirds in Flanders resulted in two Regionally Extinct species, three Endangered species and six Vulnerable species. A further seven species were considered Near Threatened and the remaining 15 species (39%) were assessed as Least Concern. Three species were classified as Data deficient. Using the Red List status, we delineated ladybird hotspots that were mainly located in grid cells with large areas of Natura2000 sites. 4. For calculating a distribution trend, we advocate the use of a high grid cell resolution (e.g.

Hesperomyces virescens is an ectoparasite of some Coccinellidae, which until the mid-1990s was relatively rarely only reported from warm regions in various parts of the world. Analysis of the host and distribution data of H. virescens recorded in the Western Palaearctic and North America reveals several trends in the occurrence and abundance of H. virescens: (1) it has recently been much more frequently recorded, (2) most of the recent records are for more northerly (colder) localities than the early records and (3) the recent records are mostly of a novel host, the invasive harlequin ladybird (Harmonia axyridis). While in North America H. virescens is almost exclusively found on H. axyridis, all European records of this association are very recent and still less numerous than records of Adalia bipunctata as a host.

BIEŃKOWSKI Institute of Animal Ecology and Evolution, Russian Academy of Sciences, Leninsky pr., 33, Moscow, 119071, Russia. E-mail: bien- [email protected] Abstract Although ladybirds of European Russia and the Caucasus have been the subject of numerous ecological and faunistic in- vestigations, there is an evident lack of appropriate identification keys. New, original keys to subfamilies, tribes, genera, and species of ladybirds (Coccinellidae) of European Russia and the Russian Caucasus are presented here. The keys in- clude all native species recorded in the region and all introduced alien species. Some species from adjacent regions are added. In total, 113 species are treated and illustrated with line drawings. Photographs of rare and endemic species are provided. Information on the distribution of species within the region under consideration is provided. Chilocorus kuwa- nae Silvestri, 1909 is recognized as a subjective junior synonym (syn. nov.) of Ch. renipustulatus (Scriba, 1791). Key words: Lady beetles, Coccinellids, determination, aborigenous species, introduced species Introduction The family Coccinellidae Latreille (ladybird beetles, lady beetles, ladybug, lady-cow) includes more than 6000 species, distributed throughout the world (Vandenberg 2002). One hundred and five species have been recorded in European Russia and the Russian Caucasus (Krasnodar Krai, Stavropol Krai, Adygea, Kabardino-Balkaria, Karachay-Cherkessia, North Ossetia, Chechnya, Dagestan, Ingushetia) (Zaslavski 1965; Iablokoff-Khnzorian 1983; Savojskaja 1984; Kovář 2007; Korotyaev et al.

Ladybirds are well known Received 20 April 2009 because of their use as biocontrol agents, and are the subject of many ecological studies. However, little Revised 15 October 2009 is known about phylogenetic relationships of the Coccinellidae, and a precise evolutionary framework is Accepted 16 October 2009 needed for the family. This paper provides the first phylogenetic reconstruction of the relationships Available online 10 November 2009 within the Coccinellidae based on analysis of five genes: the 18S and 28S rRNA nuclear genes and the mitochondrial 12S, 16S rRNA and cytochrome oxidase subunit I (COI) genes. The phylogenetic relation- Keywords: ships of 67 terminal taxa, representative of all the subfamilies of the Coccinellidae (61 species, 37 genera), Phylogeny and relevant outgroups, were reconstructed using multiple approaches, including Bayesian inference Coccinellidae Partitioned analyses with partitioning strategies. The recovered phylogenies are congruent and show that the Coccinellinae Evolution is monophyletic but the Coccidulinae, Epilachninae, Scymninae and Chilocorinae are paraphyletic.
