Nitrogen turnover of Sinella coeca (Collembola: Entomobryidae)


Eur. J. Entomol. 95 (3): 321-326, 1998

Adult collembolans we:re fed with two different food types. Leaves of Taraxacum officinale and Dactylis glomerata were given as food sources in two physical forms: either as intact leaves or as powder. Foods were labelled with 15N. The 15N uptake curves were measured. Turnover rates and turnover times were calculated. Results show that Taraxacum leaves are preferred to Dactylis leaves. The physical condition of the leaves influenced the nitrogen turnover of the animals to a large extent. Fragmentation of Dactylis leaves enhanced nitrogen utilization by roughly two-fold and decreased turnover...

Daily visual sensitivity pattern in the green lacewing Chrysoperla carnea (Neuroptera: Chrysopidae)


Eur. J. Entomol. 95 (3): 327-333, 1998

24-hour experiments on dark-adapted compound eyes of the green lacewing, Chrysoperla carnea (Stephens) show significant daily changes in absolute sensitivity to stimuli of different colors, but no daily changes in the spectral sensitivity. The absolute sensitivity is highest for all wavelengths at mid night, and lowest at noon. The daily shift of sensitivity is, however, most pronounced in the working range of the eye in the bluegreen-green region of the spectrum. The electrophysiologically measured sensitivity of the compound eye to monochromatic stimuli correlates with the size change of its superposition aperture after illumination with white...

Can Rhagoletis pomonella flies (Diptera: Tephritidae) learn to associate presence of food on foliage with foliage color?


Eur. J. Entomol. 95 (3): 335-341, 1998

Rhagoletis pomonella (Diptera: Tephritidae) flies were exposed for 3 days in laboratory cages to yellowish, green or white surrogate leaves with or without food (sucrose) on the leaf surface. When tested in an arena minutes after fly removal from an exposure cage, yellowish surrogate leaves were more attractive to tested flies than green surrogate leaves irrespective of the nature of surrogate leaves to which flies had been exposed. However, flies exposed to green surrogate leaves having food exhibited greater propensity to alight on green surrogate leaves than flies exposed to yellowish or white surrogate leaves having food. This propensity...

Ten aphid species (Sternorrhyncha: Aphididae) as prey for Adalia bipunctata (Coleoptera: Coccinellidae)


Eur. J. Entomol. 95 (3): 343-349, 1998

Ten aphid species wcre used as prey for Adalia bipunctata and six of them (Euceraphis betulae, Cavariella konoi, Liosomaphis berberidis, Acyrthosiphon ignotum, Aphis farinosa and Macrosiphoniella artemisiae) are new essential preys for this coccinellid. Eucallipterus tiliae and E. betulae were the most suitable prey according to the rate of larval development, larval mortality, adult fresh weight and coccinellid abundance in the field. They are followed by L. berberidis, C. konoi and Tuberculatus annulatus. M. artemisiae and A. ignotum are also...

The effect of plant quality and temperature on the fitness of Cinara pruinosa (Sternorrhyncha: Lachnidae) on Norway spruce


Eur. J. Entomol. 95 (3): 351-358, 1998

Many aspects in the life-history of aphids are critically dependent on the quality of their host plants and prevailing temperature. Therefore, the fitness of an aphid clone will depend on these parameters and will determine its ecological and ultimately its evolutionary success. Measuring and calculating the fitness of an organism in a natural environment is an important but also a difficult task, as many parameters that code for fitness need special assumptions, e.g. a uniform environment or stable age distribution. In this study, three aspects of environmental variability were considered: (a) the nutritional supply of the host plants (high- and low-quality...

Facultative hyperparasitism in Brachymeria pomonae (Hymenoptera: Chalcididae)


Eur. J. Entomol. 95 (3): 359-366, 1998

This report summarizes a study designed to uncover any tendency towards hyperparasitic behavior in Brachymeria pomonae (Cameron), a parasitoid of pink bollworm (PBW) (Pectinophora gossypiella Saunders) imported from Australia to California for biological control of the latter pest species. Brachymeria pomonae hyperparasitized both Apanteles oenone Nixon (ca. 10% of pupae exposed) and Cardiochiles nigriceps Viereck (ca. 23% of pupae exposed), and all hyperparasitic offspring of B. pomonae were males. However, B. pomonae's aggressive primary parasitism of several lepidopterous hosts, together with the...

Does mesh height influence prey length in orb-web spiders (Araneae)?


Eur. J. Entomol. 95 (3): 367-371, 1998

The relationship between web design and prey capture in orb-web spiders was examined by correlating the mean mesh height with the mean prey length per species taken from existing literature (15 species) and new data (Larinioides sclopetarius and Argiope keyserlingi). Pooling the data from all species, the results revealed no significant relationship. Analysing the data from L. sclopetarius and A. keyserlingi separately, no overall significant relationship was found. However, the analyses of the separate observation days showed that mesh height correlated significantly with prey length on one of the five observation days...

Life history and description of the immature stages of Eumerus purpurariae (Diptera: Syrphidae) developing in Opuntia maxima


Eur. J. Entomol. 95 (3): 373-382, 1998

Eumerus purpurariae, described from the Canary Islands (Atlantic), has been reared from the stems (platyclades) of the cactus Opuntia maxima (the first known host) on Nueva Tabarca, a Mediterranean island close to the Iberian coast. The egg, larva and puparium of E. purpurariae, as well as its life cycle on the above host-plant are described. The feeding behaviour of the larva in relation to the cephalopharyngeal skeleton morphology is analysed. Based on the present data, comparative table containing the main morphological characteristics of the injurious Eumerus species of the Palaearctic region is presented.

Taxonomic review of the genus Aesalus (Coleoptera: Lucanidae) in the Himalayas


Eur. J. Entomol. 95 (3): 407-416, 1998

The genus Aesalus F., 1801 of the family Lucanidae in the Himalayas is reviewed, and a new species, A. saburoi sp. n., is described from Central Nepal. This new species has been confused with A. himalayicus Kurosawa 1985, but differs from the latter mainly by a darker and broader body, and by different shapes of the intercoxal process of the prosternum and of male genitalia. The male of A. himalayicus sensu stricto is described for the first time and the male genitalia are illustrated. A key to the members of the genus Aesalus from the Himalayas is provided.

A revision of the genus Microtrichalus from the Philippines (Coleoptera: Lycidae)


Eur. J. Entomol. 95 (3): 417-428, 1998

The species of the genus Microtrichalus Pic, 1921 represented in the Philippines are revised. Six species are placed in the genus; in addition to M. basipennis (Pic, 1926), two species are described as new (M. retractus sp. n. and M. salvani sp. n., both from Mindanao), and three species are transferred from the genus Trichalus Waterhouse, 1877: M. bakeri (Kleine, 1929) comb. n., M. costilis (Kleine, 1926) comb. n. and M. communis (Waterhouse, 1879) comb. n. A key to the six Philippine Microtrichalus species and illustrations of their important diagnostic characters are provided. Trichalus...

Listroderes abditus or Antarctobius abditus? A simultaneous analysis of larval and adult characters (Coleoptera: Curculionidae)


Eur. J. Entomol. 95 (3): 429-436, 1998

The weevil species Listroderes abditus Enderlein belongs in the subtribe Listroderina. This species had been previously transferred to Antarctobius, based on characters from the adult morphology. However, larval characters suggest that it was placed correctly in Listroderes. A cladistic analysis of this species and nine other rhytirrhinines for which larvae are known was performed, based on 56 morphological characters (32 from larvae and 24 from adults). According to the single cladogram obtained (78 steps, CI = 0.65, and RI = 0.72), L. abditus should be included in Listroderes rather than in Antarctobius....
