Pyrrhocoris apterus (Heteroptera) - an experimental model species: A review

SOCHA R.

Eur. J. Entomol. 90 (3): 241-286, 1993

The red firebug, Pyrrhocoris apterus (L.), has been a convenient model for biological research for a long time. The interest in P. apterus increased especially with the discovery in the mid-1960's of the so-called ''paper factor'', i.e., a substance with juvenile hormone activity. Considerable research has been done on this model insect in research topics such as biogeography, embryology, developmental and reproductive biology, theoretical and applied endocrinology, biochemistry, cytogenetics and formal genetics, bionomics, ethology, pathology, voltinism, diapause, wing polymorphism, migration, pathogens, symbiotes and predators. Some...

Responses by adult Nitidulidae (Coleoptera) to synthetic aggregation pheromones, a coattractant, and effects of trap design and placement

WILLIAMS R.N., FICKLE D.S., BARTELT R.J., DOWD P.F.

Eur. J. Entomol. 90 (3): 287-294, 1993

Aggregation pheromones of the nitidulids, Carpophilus hemipterus (L.), C. freemani Dobson, C. mutilatus Erichson, and C. lugubris Murray were field tested at two sites (one in Crawford County and the other in Knox County) in Ohio. At both sites traps baited with pheromone plus bread dough caught at least five times more adult beetles than bread dough by itself. Trap design and height influenced trap catch. In most cases the nitidulid inventory technique trap yielded more nitidulids than did the wind-oriented pipe trap or the Japanese beetle trap. Trap performance in the field was dependent upon the nitidulid species responding....

Seasonal changes in ovipositional selectivity in the monophagous leaf beetle Zygogramma suturalis (Coleoptera: Chrysomelidae)

REZNIK S.Y.

Eur. J. Entomol. 90 (3): 295-301, 1993

Results from field samples indicate that the percentage of eggs laid by the monophagous leaf beetle, Zygogramma suturalis directly on the host plant (Ambrosia artemisiifolia) changes during the course of the season. These changes in oviposition were not associated with changes in the host specificity of larvae or adult beetles. In June-August the percentage of eggs laid on A. artemisiifolia was inversely correlated with Z. suturalis larval population density. It is speculated that high larval density deterred ovipositing females.

Allozyme variation in the water moth, Operophtera brumata (Lepidoptera: Geometridae), in isolated populations

VAN SAN N., SULA J.

Eur. J. Entomol. 90 (3): 303-310, 1993

Allozyme variation was investigated in winter moth adults from four isolated localities in South Bohemia. Ten gene loci, five of which were polymorphic, were studied. Significant deviations of genotype frequencies from Hardy-Weinberg equilibrium were observed at most of polymorphic loci within the populations. The average heterozygosities for winter moth populations from four ecologically distinct localities ranged from 0. 146 to 0.279. The winter moth FST mean value of 0. 171 was relatively higher than that found in most other Lepidoptera, indicating fragmented population structure. The Červené Blato population had the greatest genetic...

Isolated populations of the winter moth, Operophtera brumata (Lepidoptera: Geometridae), their heavy metal content and parasitism

VAN SAN N., SPITZER K.

Eur. J. Entomol. 90 (3): 311-321, 1993

Ten dominant heavy metals were analyzed in adults of the winter moth, Operophtera brumata (L.), from six sites in four isolated localities in South Bohemia. At all of the sites, metal concentrations conformed to the order Zn> Fe> Cu> Mn> Ni> Pb> Co> Cd> Cr> Hg. The highest concentration of toxic metals (lead and cadmium) was found in moths associated with trees along the main road in Plástovice (3.1 and 1.1 ppm, respectively), while it was lowest in the Èervené Blato peat bog (1.1 and 0.1 ppm, respectively). The main parasitoids were two tachinid flies, Cyzenis albicans Fall. and Phorocera obscura...

Lepidoptera associated with the Červené Blato bog (Central Europe): Conservation implications

SPITZER K., JAROS J.

Eur. J. Entomol. 90 (3): 323-336, 1993

The Èervené Blato bog (South Bohemia, Central Europe) is an isolated habitat with a unique relict fauna of Lepidoptera. A list of the Lepidoptera (569 species) recorded from this peat bog is given along with notes on the relict species (tyrphobionts) and their food plants. All of the stenotopic tyrphobiontic and most of the tyrphophilous species are associated with boreal and subarctic ecosystems. All the tyrphobionts feed on peat bog plants, e.g., Ledum palustre L. and Vaccinium uliginosum L. The tyrphobionts are cold-adapted boreal and subarctic species, which are associated weakly with bogs near the subarctic tree line. The...

Three new species of Choleva (Coleoptera: Leiodidae: Cholevinae) from the Caucasus and Turkey, with a key to species of the cisteloides group

RUZICKA J.

Eur. J. Entomol. 90 (3): 337-348, 1993

Three new species of Choleva from the cisteloides group are described and illustrated: Choleva (Choleva) sagittaria sp. n. and C. (C.) rousi sp. n., both from the Caucasus, and C. (C.) fencli sp. n. from the Caucasus and northeastern Turkey. The description of female of C. (C.) zolotarevi Reitter is completed. A key to species of the cisteloides group is given. New distributional data are presented for some species.

Formica balcanina sp. n., a new species related to the Formica cinerea-group (Hymenoptera: Formicidae)

PETROV I.Z., COLLINGWOOD C.A.

Eur. J. Entomol. 90 (3): 349-354, 1993

Formica balcanina sp. n. is described and illustrated from Deliblatska pescara (Deliblato Sandy Area), Serbia. This species belongs to the Formica cinerea-group, with closest resemblance to F. selysi Bondroit, 1918.

Ilseopsis (Euscrobipalpa) parki sp. n., a leaf miner and spinner on Lycium chinense in Korea (Lepidoptera: Gelechiidae)

POVOLNY D.

Eur. J. Entomol. 90 (3): 355-358, 1993

Ilseopsis (Euscrobipalpa) parki sp. n., a gelechiid micro-moth, is described from adults reared from larvae attacking the leaves of Lycium chinense Mill. (Solanaceae) in Korea. The male moth and genitalia of both sexes are figured, and the taxonomic position and bionomics of the species are discussed.

Mites (Acarina) associated with species of Trox (Coleoptera: Scarabaeidae)

MASAN P.

Eur. J. Entomol. 90 (3): 359-364, 1993

Twelve mite species [Macrocheles penicilliger (Berlese), Macrocheles sp., Uroseius infirmus (Berlese), Uroseius sp., Uropoda orbicularis (Muller), Cerratoma szekessyi Mahunka, Bakerdania decumana Krczal, Schwiebea nova (Oudemans), Schwiebea sp., Cisellipsopus microsporus Fain & Mahunka, Rhopalanoetus sp. and Listrophorus sp.] representing six families (Macrochelidae, Uropodidae, Pygmephoridae, Acaridae, Histiostomatidae and Listrophoridae) were found to be phoretic on four species of the scarabaeid genus Trox F. [T. sabulosus (L.), T. scaber...

Size and protein content of male accessory glands in the variegated grasshopper, Zonocerus variegatus (Orthoptera: Pyrgomorphidae)

MUSE W.A.

Eur. J. Entomol. 90 (3): 365-367, 1993

Male accessory glands of Zonocerus variegatus L. undergo no significant changes in size after emergence. However, their protein content, nearly doubles during the second week, and again during the fifth week, after emergence. Copulation has little effect on the protein content.
