Induction and deinduction in insect photoperiodism: Experimental evidence and a model

ZASLAVSKI V.A.

Eur. J. Entomol. 92 (2): 401-413, 1995

Experiments with the aphid Megoura viciae Buckton were directed toward quantitative analysis of the cumulative effects of different long- and short-day photoperiods, as dependent on the numbers of light-dark cycles. It has been shown that the accumulation of these effects is a nonlinear process since, as the number of the cycles experienced increases, this process gradually slows down and finally stops. From this observation a suggestion was derived that the kinetics of the cumulative effects depends on interaction of two opposite processes, viz. the increase of the effect due to summation of consecutive daily impulses (induction), and its spontaneous...

Flight activity of Coccinella septempunctata (Coleoptera: Coccinellidae) at different strata of a forest in relation to migration to hibernation sites

SAROSPATAKI M., MARKO V.

Eur. J. Entomol. 92 (2): 415-419, 1995

The flight activity of C. septempunctata was examined in a mixed oak forest, North Hungary, in 1987-1988. Malaise traps were established at the shrub level (0-2 m), the canopy level (12.5-14.5 m) and above the forest (25-27 m). A fourth trap was placed in an open grassland 200 m from the forest edge at the ground level. Exact meteorological data were registered during the season.

The highest flight activity was observed in late July - early August in both years. This period fits to the migration period of C. septempunctata to hibernation sites. In this period a ''long distance flight behaviour'' was observed in the high strata...

Influence of female age and grain availability on the ovipositional pattern of the wheat weevil Sitophilus granarius (Coleoptera: Curculionidae)

FAVA A., BURLANDO B.

Eur. J. Entomol. 92 (2): 421-426, 1995

The ovipositional patterns of Sitophilus granarius females have been studied over time, and in response to different numbers of available wheat grains. The female fecundity and the degree of grain infestation show a maximum by 20th day of adult life, and a significant decrease after 30th day. Increasing grain availability leads to a rise of both female fecundity and grain infestation, until saturation is reached. The frequency distribution of the numbers of eggs per grain shows a contagious pattern due to a tendency of females to lay more than one egg within the same grain. This behaviour is independent of female age and grain availability,...

Developmental interactions between the solitary endoparasitoid Venturia canescens (Hymenoptera: Ichneumonidae), and two of its hosts, Plodia interpunctella and Corcyra cephalonica (Lepidoptera: Pyralidae)

HARVEY J.A., THOMPSON D.J.

Eur. J. Entomol. 92 (2): 427-435, 1995

Developmental interactions between the solitary koinobiont endoparasitoid Venturia canescens, and two of its hosts, the pyralid moths Plodia interpunctella and Corcyra cephalonica, were investigated. Wasps reared from second (L2) through fifth (L5) instars of Corcyra were larger than those from the corresponding stages of Plodia, but took longer to complete development and generally suffered higher mortality. Starved L5 Plodia of a given mass produced significantly larger wasps than starved L5 Corcyra. Adult wasp size was positively correlated with the number of ovulated eggs in Venturia emerging...

Colour polymorphism in Agriotes ustulatus (Coleoptera: Elateridae): Absence of geographic and temporal variation

HONEK A., FURLAN L.

Eur. J. Entomol. 92 (2): 437-442, 1995

The proportion of melanic (with dark elytra) and non-melanic (yellow-brown elytra) adults of Agriotes ustulatus (Schaller) was established in populations from central Europe (Bohemia, Czech Republic) and the Mediterranean region (Veneto, northern Italy). Both areas, although separated by only 500 km distance, have dramatically different climate. The average proportion of melanic individuals was slightly (by 8%) but significantly greater in populations from Veneto than from Bohemia. The frequency of melanics was identical in both sexes and stable over a 11 year period as well as during the season. The apparent stability of morph frequencies in...

Apterygothrips jenseri sp. n. from Mongolia is described with illustrations. The new species is distinguished by its dark, chitinized subapical rings on antennal segment III and IV. Similar rings are not developed in other species of this genus.

A taxonomic revision of European Psilommina (Hymenoptera: Diapriidae) Part 2. The Synacra complex

MACEK J.

Eur. J. Entomol. 92 (2): 469-482, 1995

An analysis of the apomorphic and plesiomorphic character states of the European species of the ''Synacra complex'' suggests that they can best be classified in a single genus Synacra Foerster with three subgenera viz. Paratelopsilus Whittaker [new status; two species, both new: S. (P.) paupera and S. (P.) arracta], Sundholmiella Hedqvist [here reduced from generic status; one species: S. (Sundholmiella) giraudi Kieffer, comb. n.], and Synacra s. str. [three species: S. (S.) brachialis (Nees), S. (S.) holconota...
