Geographic variation in body and ovipositor sizes in the leaf beetle Plateumaris constricticollis (Coleoptera: Chrysomelidae) and its association with climatic conditions and host plants
Teiji SOTA, Masakazu HAYASHI, Tsuyoshi YAGI
Eur. J. Entomol. 104 (2): 165-172, 2007 | 10.14411/eje.2007.025
Plateumaris constricticollis is a donaciine leaf beetle endemic to Japan, which lives in wetlands and uses Cyperaceae and Poaceae as larval hosts. We analyzed geographic variation in body size and ovipositor dimensions in three subspecies (constricticollis, babai, and toyamensis) in different climatic conditions and on different host plants. In addition, the genetic differentiation among subspecies was assessed using nuclear 28S rRNA gene sequences. The body size of subspecies toyamensis is smaller than that of the other subspecies; mean body size tended to increase towards the northeast. Ovipositor length and...
A gut-specific chitinase from the mulberry longicorn beetle, Apriona germari (Coleoptera: Cerambycidae): cDNA cloning, gene structure, expression and enzymatic activity
Young Moo CHOO, Kwang Sik LEE, Bo Yeon KIM, Doh Hoon KIM, Hyung Joo YOON, Hung Dae SOHN, Byung Rae JIN
Eur. J. Entomol. 104 (2): 173-180, 2007 | 10.14411/eje.2007.026
A gut-specific chitinase gene was cloned from the mulberry longicorn beetle, Apriona germari. The A. germari chitinase (AgChi) gene spans 2894 bp and consists of five introns and six exons coding for 390 amino acid residues. AgChi possesses the chitinase family 18 active site signature and three N-glycosylation sites. Southern blot analysis of genomic DNA suggests that AgChi is a single copy gene. The AgChi cDNA was expressed as a 46-kDa polypeptide in baculovirus-infected insect Sf9 cells and the recombinant AgChi showed activity in a chitinase enzyme assay. Treatment of recombinant virus-infected Sf9 cells with...
Energy budget of wood-feeding larvae of Corymbia rubra (Coleoptera: Cerambycidae)
Eur. J. Entomol. 104 (2): 181-185, 2007 | 10.14411/eje.2007.027
The energy budget of xylem-feeding Corymbia rubra (Coleoptera: Cerambycidae) larvae was estimated by determining bioenergetic parameters. The values of several of the life history and bioenergetic parameters of this wood-feeding insect are exceptional and associated with specific adaptations to living in and feeding on wood. The energy budget of C. rubra sheds light on the life strategy of a xylem-feeder. Its slow growth (0.012 mg × mg-1 × d-1) is associated with a low consumption rate (0.097 mg × mg-1 × d-1) and the low nutritional value of its food (the assimilation efficiency is 34%). The...

Comparative behavioral and EAG responses of female obliquebanded and redbanded leafroller moths (Lepidoptera: Tortricidae) to their sex pheromone components
Ayhan GÖKÇE, Lukasz L. STELINSKI, Larry J. GUT, Mark E. WHALON
Eur. J. Entomol. 104 (2): 187-194, 2007 | 10.14411/eje.2007.029
Studies were conducted investigating the responses of female obliquebanded leafrollers, Choristoneura rosaceana (Harris) and redbanded leafrollers, Argyrotaenia velutinana (Walker) (Lepidoptera: Tortricidae), to components of their sex pheromone. Electroantennogram (EAG) recordings revealed significant responses from antennae of female moths of both species to the major pheromone component, (Z)-11-tetradecenyl acetate, at dosages ranging from 2 µg - 2 mg. However, tested individually, the minor pheromone components of the obliquebanded leafroller, (E)-11-tetradecenyl acetate and (Z)-11-tetradecenol,...
Long range movements by individuals as a vehicle for range expansion in Calopteryx splendens (Odonata: Zygoptera)
Louise WARD, Peter MILL
Eur. J. Entomol. 104 (2): 195-198, 2007 | 10.14411/eje.2007.030
1. Flight activity in zygopterans is generally restricted to short-range movements associated with foraging, reproductive activity and escape. Indeed, previous studies have suggested that Calopteryx species, including C. splendens, are relatively sedentary species, with a low tendency for long distance movements.
2. Recent observations suggest that C. splendens is expanding its northern range in the UK; in the northeast the species is now well established in Northumberland and, in the northwest, has recently spread into south-west Scotland. The current study aimed to investigate the mobility and dispersal tendency of C. splendens...
Prey preference and biomass consumption of Macrolophus pygmaeus (Hemiptera: Miridae) fed Myzus persicae and Macrosiphum euphorbiae (Hemiptera: Aphididae)
Dionyssios P. LYKOURESSIS, Dionyssios C. PERDIKIS, Maria D. GASPARI
Eur. J. Entomol. 104 (2): 199-204, 2007 | 10.14411/eje.2007.031
The predation rate of the polyphagous predator Macrolophus pygmaeus (Rambur) when offered two aphid species, Myzus persicae (Sulzer) and Macrosiphum euphorbiae (Thomas), was investigated. Equal or unequal numbers of nymphs of each instar of the aphids were offered to the predator alone or together. Aphids were placed on an eggplant leaf, together with a fifth instar nymph of the predator in a plastic Petri dish and kept in growth cabinets at 25°C, 65 ± 5% r.h., and a 16L : 8D photoperiod. The predation rate of M. pygmaeus was always higher on M. persicae than on M. euphorbiae. However, biomass consumption...
Influence of host plant on susceptibility of the aphid Acyrthosiphon pisum (Hemiptera: Aphididae) to the fungal pathogen Pandora neoaphidis (Zygomycetes: Entomophthorales)
Cezary TKACZUK, Paresh A. SHAH, Suzanne J. CLARK, Judith K. PELL
Eur. J. Entomol. 104 (2): 205-210, 2007 | 10.14411/eje.2007.032
The performance of the aphid-specific fungal pathogen Pandora neoaphidis was studied in relation to changes in herbivore resources for the pea aphid, Acyrthosiphon pisum, on different host plant species. Dose-response bioassays were conducted with A. pisum which had been reared on dwarf bean then inoculated with P. neoaphidis and returned to dwarf bean or inoculated and transferred to field bean, pea or lucerne. The smallest estimated median lethal concentration (LC50) was 7.7 conidia mm-2 (95% confidence interval 5.4-11.2) for aphids returned to dwarf bean, with LC50s of 13.0 (9.2-19.1)...
Pre-adult development and longevity in natural populations of Lymantria dispar (Lepidoptera: Lymantriidae)
Jelica LAZAREVIĆ, Vesna PERIĆ-MATARUGA, Nikola TUCIĆ
Eur. J. Entomol. 104 (2): 211-216, 2007 | 10.14411/eje.2007.033
While most theoretical models for the evolution of ageing assume that duration of pre-adult development does not affect the longevity, experimental data are still controversial and inconsistent. Here we examined the short-term and long-term pattern of pre-adult development time and longevity in populations of the gypsy moth (Lymantria dispar) originating from either oak forest (Quercus petrea), a suitable, or locust-tree forest (Robinia psedoacacia), a poor habitat. Using a full-sib design, we examined the genetic correlations between traits found in larvae reared on oak or locust-tree leaves. We detected only negative and...
Eurytoma robusta (Hymenoptera: Eurytomidae), a local key factor in the population dynamics of Urophora cardui (Diptera: Tephritidae): a comparative analysis
Helmut ZWÖLFER, Marc BÖHEIM, Erwin BECK
Eur. J. Entomol. 104 (2): 217-224, 2007 | 10.14411/eje.2007.034
Eurytoma robusta Mayr (Chalcidoidea) exploits host galls either as a primary or secondary parasitoid, an entomophytophagous inquiline or occasionally even as a predator. We present data on its ecology and impact on gall densities and population trends of the gall fly Urophora cardui (L.) on Cirsium arvense (L.) Scop. Habitat preference, host gall selection, clutch size, and high incidence of superparasitism causing empty gall cells show that E. robusta, a generalist with a broad host spectrum, is relatively poorly adapted to parasitising U. cardui. The influence of E. robusta on U. cardui in the...
The role of fungal taxa and developmental stage of mushrooms in determining the composition of the mycophagous insect community in a Japanese forest
Satoshi YAMASHITA, Naoki HIJII
Eur. J. Entomol. 104 (2): 225-233, 2007 | 10.14411/eje.2007.035
We hypothesize that differences in fungal taxonomic groups may exert a direct influence on the composition of mycophagous insect communities, and that the relative importance of taxonomy compared to other fungal traits may change as the mushrooms decay. We conducted a 3-year field survey and analyzed the species composition of mycophagous insect communities using partial canonical correspondence analysis (partial CCA). We collected 2457 mushrooms belonging to 27 genera, and 4616 insects belonging to 16 families emerged from 439 of the mushrooms. For the whole insect community, fungal genera explained 10-19% of the total variance in the family composition...

Morphological separation of host adapted taxa within the Hyalopterus pruni complex (Hemiptera: Aphididae)
Konstantinos D. POULIOS, John T. MARGARITOPOULOS, John A. TSITSIPIS
Eur. J. Entomol. 104 (2): 235-242, 2007 | 10.14411/eje.2007.037
Morphometric variation of individuals in field collected samples of the Hyalopterus pruni complex from various Prunus species and regions of Greece was examined, to determine whether this variation is correlated with the host-trees from which the aphids originated. Morphometric data for 13 parameters of aphids from 74 field samples (760 adult apterae) were analysed by canonical variates analysis (CVA). Each sample was collected from a different tree and consisted of individuals from 2-3 neighbouring leaves from the same branch. Each field sample was used as a grouping factor in the CVA. The analysis produced three clusters corresponding...
Environmental determination of the male morph in the ant Cardiocondyla obscurior (Hymenoptera: Formicidae)
Yanyang DU, Alexandra SCHREMPF, Jürgen HEINZE
Eur. J. Entomol. 104 (2): 243-246, 2007 | 10.14411/eje.2007.038
Cardiocondyla is one of the few ant genera in which winged dispersing males coexist with wingless fighter males, which predominantly mate inside their maternal nests. Male polymorphism is not genetically determined but induced by environmental conditions (e.g., a decrease in temperature). The factors leading to the production of winged males were studied in more detail by exposing colonies of C. obscurior to a specific set of rearing conditions. A "stressful" environmental condition (rearing temperature lowered on average by 5°C) experienced for at least two days, the decrease of temperature by a minimum of 3°C, and the addition of...
The compound eye of Orgyia antiqua (Lepidoptera: Lymantriidae): Sexual dimorphism and light/dark adaptational changes
Ting Fan (Stanley) LAU, Victor Benno MEYER-ROCHOW
Eur. J. Entomol. 104 (2): 247-258, 2007 | 10.14411/eje.2007.039
Structure and photomechanical changes upon light/dark adaptation in the superposition compound eyes of the highly sexually dimorphic Orygia antiqua were studied by light and electron microscopy. The eyes of the fully winged male differ from those of the wingless, sedentary female in several respects: they are significantly larger, display a more regular ommatidial array, have a wider clearzone and possess a much more substantial tracheal tapetum. However, the eyes of the female exhibit more pronounced photomechanical changes upon light/dark adaptation than those of the male. We believe that for females, on account of their limited mobility,...
Male genital variation in a moth Pammene luedersiana (Lepidoptera: Tortricidae)
Marko MUTANEN, Seppo RYTKÖNEN, Jari LINDÉN, Janne SINKKONEN
Eur. J. Entomol. 104 (2): 259-265, 2007 | 10.14411/eje.2007.040
Insect genital characters are extensively used in species level taxonomy, and their value in species delimitation is great. Based on the lock-and-key hypothesis and that genital differences function as a mechanical isolation system between species, the value of genital characters has been thought to be superior to non-genital characters. Although geographical and other kind of intraspecific variation of genitalia is often assumed very moderate, its real extent is insufficiently investigated. We examined patterns of morphological variation in the male genitalia of the tortricid moth Pammene luedersiana, using geometric morphometric tools including...
New significant fossil insects from the Upper Carboniferous of Ningxia in northern China (Palaeodictyoptera, Archaeorthoptera)
Jakub PROKOP, Dong REN
Eur. J. Entomol. 104 (2): 267-275, 2007 | 10.14411/eje.2007.041
New palaeodictyopterid Namuroningxia elegans sp. n. (Namuroningxiidae fam. n.) and archaeorthopterid Sinopteron huangheense gen. n., sp. n. (uncertain family assignment) are described from the Tupo Formation (Upper Carboniferous, Namurian, northern China, Ningxia Hui Autonomous Region). Both new taxa exhibit a unique structure of their wing venation pattern. The Namuroningxiidae fam. n. bears a mosaic of characters diagnostic of several "palaeopteran" families throughout Palaeodictyopteroida and Eupalaeoptera. This fact is highly interesting in reference to the Namurian age known for the occurrence of the first winged insects...

Revision of the Oriental leafhopper genus Toba with description of a related new genus (Hemiptera: Cicadellidae: Stegelytrinae)
Cong WEI, Mick D. WEBB, Yalin ZHANG
Eur. J. Entomol. 104 (2): 285-293, 2007 | 10.14411/eje.2007.044
The Oriental leafhopper genus Toba Schmidt is reviewed and placed in the subfamily Stegelytrinae Baker. Its type species, T. fasciculata Schmidt, and a new species T. sandakanensis Wei & Webb, are described with details of the male and female genitalia given for the first time. A related new genus and species, Paratoba longa Wei & Webb, gen. n. and sp. n., are described. The subfamily status and the morphological similarities between these two genera and other taxa are discussed.
Morphological and molecular evidence supporting the validity of Trialeurodes lauri and T. ricini (Hemiptera: Sternorrhyncha: Aleyrodidae)
Christopher MALUMPHY, M. Belen SUAREZ, Rachel GLOVER, Neil BOONHAM, Dominique W. COLLINS
Eur. J. Entomol. 104 (2): 295-301, 2007 | 10.14411/eje.2007.045
The whiteflies Trialeurodes lauri and T. ricini have been found to be moving in international plant trade. The taxonomic validity and separation of these species is relevant to the plant health quarantine services of the European Union as T. lauri is oligophagous, nor recorded as a virus vector and present in the EU, whereas T. ricini is polyphagous, reported to be a virus vector, and absent from the EU (except for the Canary Islands). Yet doubt has been cast on the validity of the two species, with the suggestion that T. lauri is merely a variant of T. ricini. The taxonomic relationship was therefore investigated...
Cleorodes Warren, 1894 does not belong in the tribe Boarmiini (Lepidoptera: Geometridae)
Jaan VIIDALEPP, Toomas TAMMARU, Niina SNÄLL, Kai RUOHOMÄKI, Niklas WAHLBERG
Eur. J. Entomol. 104 (2): 303-309, 2007 | 10.14411/eje.2007.046
The geometrid genus Cleorodes is shown to belong in the tribe Gnophini (sensu lato) and not in Boarmiini as previously assumed. The conclusion is based on an analysis of morphological characters of a number of genera in these tribes. Moreover, the result is unambiguously supported by a phylogenetic analysis of DNA sequence variation in three nuclear gene regions (segments D1 and D2 of 28S rRNA, and elongation factor 1α) and a mitochondrial gene, cytochrome oxidase-1. The phylogenetic hypothesis is based on a combined sequence data set, which was analysed using direct optimisation.

Revision of the bee genus Capicola (Hymenoptera: Apoidea: Melittidae) distributed in the Southwest of Africa
Denis MICHEZ, Connal EARDLEY, Michael KUHLMANN, Sébastien PATINY
Eur. J. Entomol. 104 (2): 311-340, 2007 | 10.14411/eje.2007.048
The bee family Melittidae (Hymenoptera: Apoidea) includes 14 genera. Most have been reviewed but not the small African genus Capicola. The present work aims to fill this gap. Based on the revision of the type material and 1272 additional specimens, we provide a comprehensive synonymic and annotated catalogue of the 12 Capicola species sensu Michener (1981). Lectotypes are designated for the previously established species Capicola braunsiana (= C. obscura syn. n.), C. cinctiventris, C. femorata, C. flavitarsis and C. rufiventris. Moreover, C. danforthi sp. n., C. flavicara sp. n.,...
Period of adult activity and response to wood moisture content as major segregating factors in the coexistence of two conifer longhorn beetles, Callidiellum rufipenne and Semanotus bifasciatus (Coleoptera: Cerambycidae)
Ryûtarô IWATA, Takahisa MARO, Yasushi YONEZAWA, Tôru YAHAGI, Yoshirô FUJIKAWA
Eur. J. Entomol. 104 (2): 341-345, 2007 | 10.14411/eje.2007.049
The cerambycid borers Callidiellum rufipenne (Motschulsky) and Semanotus bifasciatus (Motschulsky) infest coniferous logs in Japan, with the latter distributed in the north and at high altitudes, where both species occur sympatrically. Semanotus bifasciatus adults were active at low temperatures and very active after sunset, and less active but never inactive in the daytime, whereas C. rufipenne adults were usually active at high temperatures and almost only in the daytime. At an almost constant temperature, C. rufipenne adults were almost inactive at night, whereas S. bifasciatus adults showed only an obscure...
Cicadas "dig wells" that are used by ants, wasps and beetles
Eur. J. Entomol. 104 (2): 347-349, 2007 | 10.14411/eje.2007.050
There is a high density of the cicada Cryptotympana facialis (Walker) (Hemiptera: Cicadidae) in urban parks in central Japan during summer. This cicada uses its stylet to pierce holes in the trunks of keyaki trees, Zelkova serrata and then feeds on the exuding xylem sap. Three ant species, Formica japonica Motschulsky, Lasius japonicus Santschi and Crematogaster matsumurai Forel (Hymenoptera: Formicidae) were observed aggregatively feeding on these exudates. In addition, two wasp species, Polistes jokohamae Radoszkowski (Hymenoptera: Vespidae), and Ampulex dissector (Thunberg) (Hymenoptera: Sphecidae)...
