Several specimens of Mydaea lateritia (Rondani, 1866) were collected during studies of arthropod succession on pig carrions in western Poland. This is the first record of this species in Poland and the northernmost occurrence of the species. Scanning electron microscopy documentation of egg morphology of M. lateritia is presented for the first time. Hexagonal chorionic network, foliate hatching pleats, short lateral respiratory horns, dorsomedian flange and median area with smooth hexagonal network and craters are described. The egg could be classified as Mydaea-type with short respiratory horns.

This paper offers the initial description ofthe first instar larva of Protocalliphora falcozi Séguy, 1928 (Diptera: Calliphoridae) and redescription of the second and third instar larvae and puparium, as well as distinction between P. falcozi and its relative P. azurea Fallén (Diptera: Calliphoridae). The material was sampled in the National Nature Reserve Šúr (SW Slovakia) from nests of the tree sparrow (Passer montanus), which has not previously been classified as a host of P. falcozi. Knowledge of diagnostically relevant characterics to determine bird blowfly larvae and puparia will undoubtedly contribute to the current accepted phylogeny and classification of the genus Protocalliphora.

Barley thrips, Limothrips denticornis, Haliday, 1836 (Thysanoptera: Thripidae), a grass-dwelling Holarctic species represents a model example to study transport mechanisms of Thysanoptera into nests. In samples from more than 1,500 nests, barley thrips were recorded in nests of 20 vertebrate species, both birds and mammals. Applying appropriate statistics (nonparametric methods) clear clustering among nest materials and a strong relationship between presence of thrips and grass as the nest material was found. Occurrence of thrips was not associated with nest size, location or height. To validate our statistical analyses 15 wooden boxes were installed and equipped with sticky traps to record the whole year migration dynamics. Barley thrips infiltrate nests by various ways (e. g. dwelling on bark, landing from atmosphere), however most of them (88%) invade passively on nest material (grass) in spring (1st summer nesting) and autumn (winter nest building).

Sunflowermoth Homoeosoma nebulella is the most common pest of sunflowers (Helianthus annuus L.) in China. A large outbreak involving H. nebulella was discovered in Linhe of the Mongolia Autonomous Region in 2007. Different issues related to pest management were investigated in 2007–2008. Irrigation for overwintering could promote pest outbreak in the following year. It is the safest practice to sow from mid-May to mid-June, i.e. not too early. The quantity of larvae could be reduced by the treatment with Bacillus thuringiensis. The effective pest management should include selecting proper sowing date, non-irrigation and B. thuringiensis treatment. Sex pheromone trapping as a potential control measure requires further studies.

Of these, 6 species and 3 genera (Arotes, Coleocentrus, Procinetus) and 1 tribe (Coleocentrini) from Acaentinae, 4 species and 2 genera (Arenetra and Exetastes) from Banchinae, 7 species and 1 genus (Rhimphoctona) from Campopleginae, 4 species from Ophioninae and 4 species of Tryphoninae are new records for the Iranian ichneumonid fauna. Previously recorded species are also included. Distributional maps are given for all records. This study increases the number of known Iranian ichneumonids of Acaentinae to 7, Banchinae to 7, Campopleginae to 26, Ophioninae to 18, and Tryphoninae to 23 species.

A new species of the genus Euplectus Leach, 1817, E. lapponicus sp. n. Löbl & Mattila, is described from the North Boreal zone of Finland. The species is distinctive, and may be easily distinguished by the reduced number of elytral foveae, in combination with the size of the body, the punctation, and the genital characters.

A new species, Duvalius karaormanicus sp. n., in the subgenus Euduvalius, is described from the type locality: Mlečnik cave in the Karaorman Mountain in the south-western part of the Republic of Macedonia. This is the second cave-dwelling Duvalius and the sixth representative of the genus so far recorded from the Republic of Macedonia. Based on its diagnostic characters, the new species is found to be related to the species in the “gogalai” and “petroclzilosi” groups. D. karaormanicus sp. n. occupies an intermediate position between the species from these two groups and is therefore placed in a separate “karaormanicus” species group.

Objectives are to elucidate whether populations of Carabus arvensis Herbst, 1784 from contrasting habitats differ in (i) colour, (ii) brightness of metal lustre, or (iii) body size (length of elytra, of elytra + pronotum, and width of pronotum). Two large populations were studied, originating from (a) open heathland, being a remnant from more widespread heaths during former centuries, and (b) mature pine forest established 100–150 years ago on sandy agricultural land. Heath individuals had significantly more brilliant metal lustre and mostly lighter, vivid copper colour than pine forest individuals, which were typically black with a violet shade and slightly larger in size. The two populations are nowadays isolated, which was probably not the case 1–2 centuries ago, when both sites studied were treeless. The usually blackish colour of the forest population could be a recent adaptation to the changed environment, though some influence of processes such as genetic drift cannot be excluded.

Temperate water striders (Gerridae) overwinter as adults and die after spring reproduction. European water cricket Velia caprai (Veliidae) overwinters concurrently in egg and adult stage in Central Europe. This rare overwintering strategy goes with longevity ofthis species. Adults can survive two winters in Central Europe, unlike other semiaquatic bugs. Scandinavian populations of V. caprai and water striders Gerris lacustris and G. lateralis were examined at the beginning and end of September to determine their life histories. Both gerrids start to overwinter during September, females prior to males and macropterous individuals prior to brachypterous. All females of G. lacustris and G. lateralis enter reproductive diapause before winter. V. caprai overwinters in both adult and egg stage in Norway, and can probably survive two winters. Central European and Scandinavian populations of V. caprai share the same unusual way of overwintering and probably also the whole life history.

Life history traits were evaluated in the wing polyphenic aphid, Sitobion avenae (Fabricius), by rearing the winged and wingless morphs under the laboratory conditions. Winged morph with large thoraces exhibited a significantly greater morphological investment in flight apparatus than wingless morph with small thoraces. Compared to the winged morph, the wingless morph produced significantlymore nymphs and exhibited significantly faster nymph development rates. In addition, the age at which reproduction first occurred for the winged morph was significantly delayed, and higher mortality was recorded.The results suggest that the fitness differences associated with wingsmay be related to nymph development, adult fecundity, and mortality. Based on these results, the trends and exceptions of life history traits for the wing polyphenic insects are discussed.
