Saber SADEGHI, Tina KYNDT, Henri J. DUMONT
Eur. J. Entomol. 107 (2): 137-146, 2010 | 10.14411/eje.2010.019
Calopteryx splendens is a widely distributed palaearctic damselfly with a remarkably uniform morphology. Variation in the size and shape of the pigmented spot on the wing is the main diagnostic character used to discriminate subspecies across its huge geographic range. Here, AFLP analysis was used to assess the genetic structure and diversity of nine populations representing 3 putative subspecies and evaluate the pigment spot as a taxonomic marker. Genetic diversity was high, with the number of polymorphic loci per population ranging from 141 to 280 out of a total of 333 variable sites (42.3-84.1%) and Nei's gene diversity from 0.160 to 0.283 (overall...

The sequence diversity in the mitochondrial cytochrome-c oxidase I (COI) gene was evaluated as a tool for resolving differences among species of European adelgids collected from several localities across the Czech Republic. Members of 7 genera and 16 species were examined, and as outgroups, two species of Phylloxeridae were used. Sequence divergences within species were on average less than 0.15%, whereas divergences between species ranged from 0.0 to 4.12% for congeneric and to 13.24% for intergeneric comparisons. It is concluded that DNA barcoding of Adelgidae is a powerful tool for identifying genera, but at the species level it works only...
Genetic polymorphism in "mixed" colonies of wood ants (Hymenoptera: Formicidae) in southern Finland and its possible origin
Julita KORCZYÑSKA, Marta GAJEWSKA, Malgorzata PILOT, Wojciech CZECHOWSKI, Alexander RADCHENKO
Eur. J. Entomol. 107 (2): 157-167, 2010 | 10.14411/eje.2010.021
Wood ant colonies that appear to consist of individuals representing different species are described in several previous papers. The present study is the first to elucidate the genetic basis of the spectacular morphological variability observed within such colonies. Two seemingly mixed colonies (FM-1 and FM-2) from southern Finland were investigated. On the basis of the morphology of their workers these colonies were comprised of individuals with phenotypes typical of Formica rufa L., F. polyctena Först., and F. aquilonia Yarr. The sequence of an mtDNA fragment (5' end of the cytochrome b gene) was used to examine the phylogenetic...
Host recognition and acceptance behaviour in Cotesia sesamiae and C. flavipes (Hymenoptera: Braconidae), parasitoids of gramineous stemborers in Africa
Meshack OBONYO, Fritz SCHULTHESS, Bruno LE RU, Johnnie VAN DEN BERG, Paul-André CALATAYUD
Eur. J. Entomol. 107 (2): 169-176, 2010 | 10.14411/eje.2010.022
The host recognition and acceptance behaviour of two braconid larval parasitoids (Cotesia sesamiae and C. flavipes) were studied using natural stemborer hosts (i.e., the noctuid Busseola fusca for C. sesamiae, and the crambid Chilo partellus for C. flavipes) and a non-host (the pyralid Eldana saccharina). A single larva was introduced into an arena together with a female parasitoid and the behaviour of the wasp recorded until it either stung the larva or for a maximum of 5 min if it did not sting the larva. There was a clear hierarchy of behavioural steps, which was similar for both parasitoid species....
Multiple matings affect the reproductive performance of the aphidophagous ladybird beetle, Coelophora saucia (Coleoptera: Coccinellidae)
OMKAR, Satyendra K. SINGH, Geetanjali MISHRA
Eur. J. Entomol. 107 (2): 177-182, 2010 | 10.14411/eje.2010.023
The effect of multiple matings on the readiness with which mating occurred, fecundity, egg viability and adult longevity in the aphidophagous ladybird beetle, Coelophora saucia (Mulsant) (Coleoptera: Coccinellidae), was investigated under laboratory conditions. The time to onset of mating after previous pairing was found to decrease with increase in the number of matings. Multiply mated females had a higher fecundity and egg viability than single mated females. The trends in the results were analyzed using both binomial regression and the Gompertz equation. The best fitting curve was that based on the binomial equation, which indicates...
Effect of temperature on the interaction between Chrysoperla externa (Neuroptera: Chrysopidae) and Sipha flava (Hemiptera: Aphididae)
Simone A. OLIVEIRA, Alexander M. AUAD, Brígida SOUZA, Daniela M. SILVA, Caio A. CARVALHO
Eur. J. Entomol. 107 (2): 183-188, 2010 | 10.14411/eje.2010.024
This paper examines some biological aspects and the predatory capacity of Chrysoperla externa fed nymphs of Sipha flava and reared at different temperatures. Recently hatched larvae were placed individually in Petri dishes, fed ad libitum with S. flava and reared at either 12, 16, 20, 24, 28 or 32 ± 1°C, a RH of 70 ± 10% and a 12-h photophase. The experiment was fully randomized with 30 replicates of each treatment. The duration and survival in each instar, and larval and pupal stages (pre-pupa + pupa) were analyzed. To determine the predatory capacity of larvae they were each provided daily with...

Nick BERKVENS, Carmen LANDUYT, Koen DEFORCE, Dirk BERKVENS, Luc TIRRY, Patrick DE CLERCQ
Eur. J. Entomol. 107 (2): 189-195, 2010 | 10.14411/eje.2010.025
The multicoloured Asian lady beetle Harmonia axyridis (Coleoptera: Coccinellidae) may potentially exploit a range of "alternative" food sources. The nutritional value of three common non-prey food groups, i.e. fruit, fungi and pollen, is examined in this study. Development, reproduction and survival of the species were assessed in the laboratory on diets of apple, pear and raspberries and the fungi Oidium lycopersicum, Botrytis cinerea, Sclerotinia sclerotiorum and Rhizoctonia solani. When fed exclusively on these foods this ladybird failed to complete its development or reproduce. However, larval and adult...
Selective oviposition in fertilized seed of Ilex integra by the wasp Macrodasyceras hirsutum (Hymenoptera: Torymidae)
Etsuro TAKAGI, Kazunobu IGUCHI, Masanori SUZUKI, Katsumi TOGASHI
Eur. J. Entomol. 107 (2): 197-202, 2010 | 10.14411/eje.2010.026
It is speculated that the wasps that attack the seeds of gymnosperm trees (conifers) before they are fertilized can induce unfertilized seeds to accumulate storage material whereas those that attack after the seeds are fertilized selectively oviposit in fertilized seeds. Moreover, in the case of the wasps that oviposit after fertilization of seed, the presence of unfertilized seeds and seedless fruit may increase plant fitness via reduced parasitism of the viable seed. To determine the relationship between the two strategies, host manipulation or selective oviposition, and the time of fertilization of the seeds of angiosperm host plants, fertilized...
Does climate influence phenological trends in social wasps (Hymenoptera: Vespinae) in Poland?
Piotr TRYJANOWSKI, Tadeusz PAWLIKOWSKI, Krzysztof PAWLIKOWSKI, Weronika BANASZAK-CIBICKA, Tim H. SPARKS
Eur. J. Entomol. 107 (2): 203-208, 2010 | 10.14411/eje.2010.027
Responses of insects to recent climate change have been well documented in a number of taxa, but not in wasps. This study examined shifts in phenology of the two most important wasp species (Vespa crabro and Vespula germanica) in Poland over the last three decades. Both species showed similar temporal trends, advancing their phenology after the early 1980s, but this pattern was detected only for workers not for the appearance of queens. The appearance times for V. germanica were negatively related to mean April temperature, appearing earlier in years with warmer springs, and positively related to precipitation in April. The studied...
Present conservation status of red wood ants in north-western Belgium: Worse than previously, but not a lost cause
Wouter DEKONINCK, Frederik HENDRICKX, Patrick GROOTAERT, Jean-Pierre MAELFAIT
Eur. J. Entomol. 107 (2): 209-218, 2010 | 10.14411/eje.2010.028
The number of colonies of red wood ants (Formica rufa group) in the north western part of Belgium has declined by more than half over the past 20 years. In the study area of 20 × 50 km there are currently only 36 colonies of two species of red wood ants (Formica rufa and F. polyctena). Both species form both monodomous and polydomous colonies. Monodomous F. rufa colonies occur in large areas of open woodland dominated by Pinus sylvestris. The other three types of red wood ant (F. rufa polydomous, F. polyctena mono- and polydomous) occur in clearings or along the margins of small areas of deciduous...

Rocío ROSA GARCÍA, Francisco J. OCHARAN, Berta M. JÁUREGUI, Urcesino GARCÍA, Koldo OSORO, Rafael CELAYA
Eur. J. Entomol. 107 (2): 219-227, 2010 | 10.14411/eje.2010.029
The abundance, diversity and community composition of ground-dwelling arthropods present in three different types of Cantabrian heathland grazed by small ruminants were studied. A factorial design of three vegetation types (heather-, gorse- or grass-dominated) and two grazer species (sheep or goats) with two replicates was established in twelve 0.6 ha paddocks. Ground-dwelling arthropods (Araneae, Opiliones, Isopoda, Julida, Microcoryphia, Hemiptera, Coleoptera and Hymenoptera) were recorded using pitfall traps and plant cover and canopy height assessed in each paddock in 2005, 2006 and 2007. Higher abundances and more families of ground dwelling arthropods...

Altitudinal distribution of moths (Lepidoptera) in Mt. Jirisan National Park, South Korea
Sei-Woong CHOI, Jeong-Seop AN
Eur. J. Entomol. 107 (2): 229-245, 2010 | 10.14411/eje.2010.031
The relationship between species richness of plants and animals and altitude can be either hump-shaped, a monotonic decrease or increase. In this study the altitudinal distribution of moths on one of the highest mountains in South Korea was investigated. Moths were captured using a UV-light trap from May to October in 2007 and 2008. This revealed that the relationship between the total numbers of moth species and individuals and altitude is hump-shaped. A significant relationship was also recorded between the size of the area at each altitude and moth abundance and richness. However, the evenness index yielded a consistent decrease with increase in...

Review of the genus Agnippe (Lepidoptera: Gelechiidae) in the Palaearctic region
Oleksiy BIDZILYA, Houhun LI
Eur. J. Entomol. 107 (2): 247-265, 2010 | 10.14411/eje.2010.033
The genus Agnippe Chambers, 1872 in the Palaearctic Region is revised. Sixteen species are recognized as valid. Three new synonyms are established: A. conjugella Caradja, 1920 = A. haberlandii Amsel, 1961 syn. n., A. lunaki Rebel, 1941 = A. penicillata Amsel, 1961 syn. n., A. kuznetzovi Lvovsky & Piskunov, 1989 = A. zhengi Li, 1993 syn. n. Four new species are described: A. echinuloides sp. n. (S Ural, Tuva, Transbaikalia, Mongolia), A. turanica sp. n. (Uzbekistan, Kazakhstan), A. deserta sp. n. (Uzbekistan) and A. separatella sp. n. (S Iran). Description...
Isolation and characterization of six microsatellite loci in the larch budmoth Zeiraphera diniana (Lepidoptera: Tortricidae)
Sophie DELAMAIRE, G. Danny ESSELINK, Leila SAMIEI, Claudine COURTIN, Emmanuelle MAGNOUX, Jérôme ROUSSELET, M.J.M. SMULDERS
Eur. J. Entomol. 107 (2): 267-269, 2010 | 10.14411/eje.2010.034
Six microsatellite markers were developed for the larch budmoth Zeiraphera diniana Guénée 1845, using two enrichment protocols. The number of alleles ranged from 3 to 15 per locus and observed heterozygosities ranged from 0.09 to 0.98 for the 69 individuals genotyped. Using these markers significant genetic differentiation between one population from Poland and samples from Alpine populations in France and Switzerland (overall FST = 0.0298) was detected. However, the two Alpine samples did not differ significantly. These microsatellite markers are valuable tools for studying the population genetics of Zeiraphera diniana.
Enhanced tolerance to water stress in adults of the South India strain of the seed beetle, Callosobruchus maculatus (Coleoptera: Bruchidae), as a product of large body size
Jay A. YODER, Brady S. CHRISTENSEN, George D. KEENEY
Eur. J. Entomol. 107 (2): 271-275, 2010 | 10.14411/eje.2010.035
A water balance study was conducted on newly-emerged adults of seed beetle, Callosobruchus maculatus, to explore how South India strain survives longer than Brazil strain in laboratory cultures. No difference between strains was noted with regard to dehydration tolerance, and water conservation features confirm classification of this species as xerophilic. There was no evidence for critical transition temperature (CTT), thereby safeguarding against excessive water loss as the temperature rises, or for critical equilibrium humidity (CEH), indicating that water is imbibed as a liquid. In contrast to the Brazil strain, adults of the South...
Effect of the colour of pitfall traps on their capture efficiency of carabid beetles (Coleoptera: Carabidae), spiders (Araneae) and other arthropods
Sascha BUCHHOLZ, Anna-Marie JESS, Florian HERTENSTEIN, Jens SCHIRMEL
Eur. J. Entomol. 107 (2): 277-280, 2010 | 10.14411/eje.2010.036
Pitfall trapping is one of the most commonly used methods of sampling ground-dwelling arthropods. There are many studies on the effect of design of pitfall traps on their capture efficiency but, so far, none on the influence of the colour of the pitfall trap. In this study the abundances of seven invertebrate groups (Apidae, Araneae, Carabidae, Diptera, Formicidae, Isopoda, Vespinae) caught in pitfall traps of different colours (white, yellow, green, brown) at a dense and dry grassland site in Northwestern Germany were determined. White and yellow pitfall traps caught by far the highest numbers of individuals of Apidae, Araneae, Carabidae, Diptera...
