Eur. J. Entomol. 99 (3): 267-276, 2002 | 10.14411/eje.2002.037
RFLP clones harbouring multi-copy DNA sequences were isolated from the Pst I sub-genomic library of the indigenous silkworm race, Nistari, and were used for DNA fingerprinting studies in 13 stocks of silkworm, Bombyx mori L. Six multilocus probes produced 180 RFLP markers that showed a high level (98%) of polymorphism and are highly useful in molecular mapping, genotype characterization and marker assisted selection (MAS). The dendrogram derived from UPGMA analysis clearly divides the 13 silkworm stocks into two major clusters: high- and low-yield stocks. Furthermore, adopting multiple regression analyses, the RFLP marker(s) associated...
Superparasitism by Torymus cyanimus (Hymenoptera: Torymidae) in the Volga-Kama region
Vladimir M. BASOV
Eur. J. Entomol. 99 (3): 277-284, 2002 | 10.14411/eje.2002.038
On the basis of a twenty-year investigation, the life-cycle of Torymus cyanimus Boheman (Hymenoptera: Torymidae), a hyperparasitoid of a gall-forming fly in the Volga-Kama region is described. This parasitoid is the top-consumer in a food chain on Cirsium setosum (Willdenow) Iljin, in which the herbivore is Urophora cardui L. (Diptera: Tephritidae) and the primary parasitoids belong to the genus Eurytoma (Hymenoptera: Eurytomidae). Mating and oviposition behaviour were studied, and the superparasitism and larval cannibalism investigated in the second parasitoid generation. The superparasitism in T. cyanimus evolved...
Effect of innate preferences, conditioning and adult experience on the attraction of Aphidius ervi (Hymenoptera: Braconidae) toward plant volatiles
Luis C. RODRÍGUEZ, Eduardo FUENTES-CONTRERAS, Hermann M. NIEMEYER
Eur. J. Entomol. 99 (3): 285-288, 2002 | 10.14411/eje.2002.039
The aphid parasitoid Aphidius ervi was collected and subsequently reared on Sitobion avenae on wheat or Acyrthosiphon pisum on alfalfa. Parasitoids from both origins were exposed in an olfactometer to alfalfa or wheat volatiles after plant experience (wheat or alfalfa) or after oviposition experience (S. avenae on wheat or A. pisum on alfalfa). The results showed the importance of adult experience, conditioning and innate preferences on the responses of A. ervi toward volatiles and provided a mechanistic explanation to the high prevalence of A. ervi on aphids on cereals and legumes in central Chile.
The assemblages of aquatic Coleoptera from shallow lakes in the northern Iberian Meseta: Influence of environmental variables
Luis F. VALLADARES, Josefina GARRIDO, Francisco GARCÍA-CRIADO
Eur. J. Entomol. 99 (3): 289-298, 2002 | 10.14411/eje.2002.040
Aquatic Coleoptera in shallow lakes associated with the Canal de Castilla (Palencia Province, Spain) in the northern Iberian Meseta were sampled over the course of a year (spring 1998-winter 1999). These waterbodies are typical plateau wetlands with dense vegetation and vary in permanence and area (from 3.3 ha to 29.35 ha). Oxygen concentration, conductivity and pH were recorded at the time of sampling. Lake area, depth, water permanence and type of vegetation were also taken into account. Ninety two species were collected. Species richness was high in comparison with other wetlands in Spain. The assemblage structure was assessed in terms of three...
Review of the genus Stenodera with a description of the first instar larva of S. puncticollis (Coleoptera: Meloidae)
Marco A. BOLOGNA, Andrea DI GIULIO, John D. PINTO
Eur. J. Entomol. 99 (3): 299-313, 2002 | 10.14411/eje.2002.041
The first instar larva, or triungulin, of Stenodera puncticollis (Chevrolat, 1829) is described. Its characters indicate that Stenodera is the most primitive member of the subfamily Nemognathinae and support the recognition of the monotypic tribe Stenoderini, as previously proposed on the basis of adult morphology. The bionomic information on this genus is summarized, and an annotated catalogue and key to the species based on adults are presented.

Generic revision and phylogenetic analysis of the Metriorrhynchinae (Coleoptera: Lycidae)
Eur. J. Entomol. 99 (3): 315-351, 2002 | 10.14411/eje.2002.043
The subfamily Metriorrhynchinae is the most species-rich clade of Lycidae (Coleoptera). A recent proposal suggests that the Erotinae is a sister group of the Metriorrhynchinae. Within the Metriorrhynchinae, evidence is presented for the monophyly of the Conderini and Metriorrhynchini and their sister group position. The Trichalina, Hemiconderina and Metriorrhynchina form the tribe Metriorrhynchini. The relationships between the basal lineages of this group are poorly understood. Several clades are distinguished within the Metriorrhynchina, but there is only weak evidence supporting a relationships between them. The distribution of individual clades...

Eur. J. Entomol. 99 (3): 353-361, 2002 | 10.14411/eje.2002.045
One new genus and nine new species of Staphylinidae are described from Baltic amber, namely Palaeosepedophilus gen.n. and the species P. succinicus sp.n., Lathrobium balticum sp.n., Lathrobium succini sp.n., Lathrobium ambricum sp.n., Lathrobium jantaricum sp.n., Sepedophilus balticus sp.n., Dictyon antiquus sp.n., Phymatura electrica sp.n., Aleochara baltica sp.n. Their affinity with related species is discussed.

The larva of Chiron senegalensis and comments on its relationships with other Scarabaeoidea (Coleoptera: Chironidae)
Jean-Bernard HUCHET, Jean-Pierre LUMARET
Eur. J. Entomol. 99 (3): 363-372, 2002 | 10.14411/eje.2002.047
After a brief presentation of some historical, taxonomical and biological data on the Chironidae, the third instar larva of Chiron senegalensis Hope & Westwood, 1845 is described and illustrated on the basis of larval characteristics. The systematic position of the genus Chiron Mac Leay, 1819 within the Scarabaeoidea complex is discussed.
A review of the European planthopper genus Trirhacus and related taxa, with a key to the genera of European Cixiidae (Hemiptera: Fulgoromorpha)
Werner E. HOLZINGER
Eur. J. Entomol. 99 (3): 373-398, 2002 | 10.14411/eje.2002.048
Ten species of Cixiidae, formerly placed in Trirhacus Fieber, 1875, are redescribed and one additional species is described. They belong to seven genera: Trirhacus s. str. with T. setulosus Fieber, 1876 (type species), T. dubiosus Wagner, 1959, T. biokovensis Dlabola, 1971 and T. peloponnesiacus sp. n., Apartus gen. n. with A. michalki (Wagner, 1948) comb. n. (type species) and A. wagnerianus (Nast, 1965) comb. n., Nanocixius Wagner, 1939 stat. n. with N. discrepans (Fieber, 1876) comb. n., Neocixius Wagner, 1939 stat. n. with N. limbatus (Signoret,...
Temperature and the development rates of thrips: Evidence for a constraint on local adaptation?
David A. STACEY, Mark D.E. FELLOWES
Eur. J. Entomol. 99 (3): 399-404, 2002 | 10.14411/eje.2002.049
Typically, the relationship between insect development and temperature is described by two characteristics: the minimum temperature needed for development to occur (Tmin) and the number of day degrees required (DDR) for the completion of development. We investigated these characteristics in three English populations of Thrips major and T. tabaci [Cawood, Yorkshire (N53°49', W1°7'); Boxworth, Cambridgeshire (N52°15', W0°1'); Silwood Park, Berkshire (N51°24', W0°38')], and two populations of Frankliniella occidentalis (Cawood; Silwood Park). While there were no significant differences among populations in either Tmin...
