Eur. J. Entomol. 98 (3): 257-264, 2001 | 10.14411/eje.2001.042
The activity and number of protocerebral neurosecretory neurons of the dorsolateral group (L1, L2 and L2'), as well as the size of the corpora allata were investigated in 5th instar larvae of the gypsy moth (Lymantria dispar) from two populations (oak and locust-tree forests) fed one of two host-plants (oak is a suitable and locust-tree an unsuitable host-plant).
The monitoring of activity related cytological parameters and the number of protocerebral dorsolateral neurosecretory neurons revealed that differently adapted populations respond to nutritive stress differently. The activity of the L1 neurosecretory neurons in the protocerebra of...
The effect of starvation on the metabolic rate and microanatomy of Galumna elimata (Acari: Oribatida)
Jan HUBERT, Vladimír ŠUSTR
Eur. J. Entomol. 98 (3): 265-275, 2001 | 10.14411/eje.2001.043
The physiological parameters mortality, mass, oxygen consumption and amylase activity, and microanatomical features of the digestive tract, mesenchym and reproductive organs were used to characterise starvation in Galumna elimata. The mites were reared in sterilised plastic vials containing moistened zeolite at 25°C and a 12:12 photoperiod. The control group was kept under the same conditions, but pieces of bark covered with the green bark alga, Desmococcus vulgaris (syn. Protococcus viridis), were added as food for the mites. The physiological parameters were recorded after 21 days, and the microanatomical after 21 and...

Large larvae of a flush-feeding moth (Epirrita autumnata, Lepidoptera: Geometridae) are not at a higher risk of parasitism: implications for the moth's life-history
Tiit TEDER, Toomas TAMMARU
Eur. J. Entomol. 98 (3): 277-282, 2001 | 10.14411/eje.2001.045
The effect of larval body size of Epirrita autumnata (Lepidoptera, Geometridae) on the risk of parasitism was studied in a field experiment. The experiment involved three pairwise exposures of different larval instars to parasitoids. Three hymenopteran species were responsible for most of the parasitism. Parasitism risk was found to be host-instar independent. This result was consistent across parasitoid species and experiments. The results suggest that host use by larval parasitoids cannot constrain selection for larger body size in E. autumnata. However, high mortality due to parasitism may select for a short developmental period (the...
Response of chrysopids (Neuroptera) to larval tracks of aphidophagous coccinellids (Coleoptera)
Eur. J. Entomol. 98 (3): 283-285, 2001 | 10.14411/eje.2001.046
Choice tests showed that tracks left by coccinellid larvae have generally little effect on oviposition site selection by chrysopid females. Fresh tracks of first instar larvae of the coccinellid species Coccinella septempunctata, Cycloneda limbifer, Leis dimidiata and Semiadalia undecimnotata, did not deter females of the chrysopid Chrysopa oculata from laying eggs. Females of Chrysopa perla avoided ovipositing only on substrates with tracks of L. dimidiata larvae.

Fitness of two phenotypes of Harmonia axyridis (Coleoptera: Coccinellidae)

Eur. J. Entomol. 98 (3): 287-293, 2001 | 10.14411/eje.2001.048
The coccinellid H. axyridis shows considerable intraspecific variability of elytral patterns. In this paper, we suggest that a genotype that confers a specific pattern of elytra could also confer other specific autecological attributes. The aim of this paper is to compare fitness parameters of two phenotypes (aulica and nigra). Aulica is a common morph characterized by two light red areas that nearly cover the whole elytra, leaving a narrow black border, whereas nigra is completely black; the latter is a rare morph that was naturally obtained from mass cultures. Intraspecific differences occur between H. axyridis...

An experimental investigation of patterns of parasitism at three spatial scales in an aphid-parasitoid system (Hymenoptera: Aphidiidae)
Vojtich JAROŠÍK, Laurent LAPCHIN
Eur. J. Entomol. 98 (3): 295-299, 2001 | 10.14411/eje.2001.050
Density dependent host mortality in the interaction between the solitary endoparasitoid Aphidius colemani (Aphidiidae), and its host, the green peach aphid Myzus persicae, was examined on greenhouse peppers. The experimental approach attempted to eliminate spatial interdependence in the relationship between host density and host mortality by using different plants to measure parasitism at different spatial scales. Increasing host density at the plant scale caused a significant increase in the proportion of host mortality. However, at the shoot and leaf scale, increasing host density caused a significant decrease in host mortality. This...

Arthropod distribution on an alpine elevational gradient: the relationship with preferred temperature and cold tolerance
Alan BUSE, David HADLEY, Tim SPARKS
Eur. J. Entomol. 98 (3): 301-309, 2001 | 10.14411/eje.2001.052
The distribution of arthropod species on a 400 m elevational gradient (equivalent to a temperature decrease of 2.5°C) on Snowdon, North Wales, was examined and compared with the British distribution. Preferred temperature, an indication of optimal body temperature (Tb), and supercooling point (SCP), an indication of cold tolerance, of several species on the gradient were determined experimentally. The alpine beetle species Patrobus assimilis and Nebria rufescens had low preferred Tb, of 5.6 and 7.1°C respectively, whereas the more widespread upland species had higher preferred Tb, between 12.9 and 15.5°C....

Larval morphology of some Anisopliini grain beetles with a key to their larvae (Coleoptera: Scarabaeoidea: Rutelidae: Anomalinae)
Estefanía MICÓ, José R. VERDÚ, Eduardo GALANTE
Eur. J. Entomol. 98 (3): 311-320, 2001 | 10.14411/eje.2001.054
The third instar larvae of three Anisoplia species, Anisoplia baetica Erichson, 1847, Anisoplia depressa Erichson, 1847 and Anisoplia remota Reitter, 1889 are described and illustrated to show the diagnostic characters of the species. The third instar larva of the monospecific genus Anthoplia, represented by Anthoplia floricola (F., 1787) is also described and illustrated. These four species are included in a revised key to the larvae of Anisopliini, which now includes four genera, and ten species. The taxonomic status of Anthoplia based on the larval morphology, is discussed.

Eur. J. Entomol. 98 (3): 321-350, 2001 | 10.14411/eje.2001.055
A revision of species of the Australian burrower bug genus Blaena Walker, 1868 is presented. Eight previously known species are redescribed and four new ones, B. hirta n. sp. (Queensland), B. parathroposa n. sp. (Queensland), B. pseudosetosa n. sp. (Western Australia), and B. serrata n. sp. (Northern Territory, Queensland, Western Australia) are described and illustrated. The male and female genitalia of all the species of the genus are studied for the first time. A key for species determination is also provided.
Seven new montane species of Drosophila in the Eastern Arc mountains and Mt Kilimanjaro in Tanzania attesting to past connections between eastern and western African mountains (Diptera: Drosophilidae)

Eur. J. Entomol. 98 (3): 351-366, 2001 | 10.14411/eje.2001.056
This report describes 7 new species of Drosophila found in the Eastern Arc mountains and on Mount Kilimanjaro in Tanzania: D. baucipyga, D. gata, D. kilimanjarica, D. neogata, D. paragata, D. pilocornuta and D. usambarensis spp.n. Two new species complexes, the megapyga species complex (Sophophora subgenus, melanogaster group, montium subgroup) and the gata species complex (Drosophila subgenus) are introduced. Only one species, D. baucipyga of the montium subgroup, has a geographical range matching the whole Eastern Arc, from the Usambara...
Scuttle flies (Diptera: Phoridae) whose larvae develop in flowers of Aristolochia (Aristolochiaceae) in Panama
R. Henry L. DISNEY, Shoko SAKAI
Eur. J. Entomol. 98 (3): 367-373, 2001 | 10.14411/eje.2001.057
Megaselia metropolitanoensis Disney, sp. n., M. sakaiae Disney, sp. n. and Puliciphora pygmaea (Borgmeier, 1960) comb. n. are reported developing in the flowers of Aristolochia inflata H. B. K. and A. maxima Jacq. in Panama. The new species are described, as is the hitherto unknown male of Puliciphora pygmaea. The latter is transferred to the the genus Puliciphora Dahl, 1897 from the genus Myrmomyia Silvestri, 1911 which is formally synonymised with Puliciphora, along with P. brachymyrmecis (Silvestri, 1911) comb. n. and P. nigroflava (Borgmeier, 1958) comb. n.

Eur. J. Entomol. 98 (3): 375-385, 2001 | 10.14411/eje.2001.058
Adults of Copestylum tamaulipanum and C. lentum were reared from larvae collected from decaying platyclades of the cactus Opuntia in the state of Veracruz (Mexico). The larvae and puparia of both species, as well as preliminary data about their life cycles are described. The feeding behaviour of the larva in relation to the morphology of the cephalopharyngeal skeleton is analysed.
