    Description: Global warming and the change of butterfly distributions: a new opportunity for species diversity or a severe threat (Lepidoptera)? \nIn order to assess the influence of climatic changes on the distribution of insects, the ranges of nonmigratory European butterfly species have been studied. This study revealed that the northern limits of 32 (64%) of 52 species have expanded northwards during the 20th century. The southern limits of ten (25%) of 40 species have retracted northwards. The example of the Peacock butterfly (Inachis io) is given to illustrate the response to climatic changes of a species of which the range is not restricted by habitat choice. The northern limit of its range shows a considerable shift to the north during warm periods, and a southward retraction during cooler periods. Several other species showed the same pattern. These results are followed by a discussion of the impact of climate change on species diversity.

    Description: Post-glacial dispersal strategies of Orthoptera and Lepidoptera in Europe and in the Carpathian basin \nEcologically transitional regions are characterised by high species diversity due to the overlap of species with different geographical origins caused by dispersal processes along gradients, e.g. the overlap of species belonging to different zonobiomes. The overlap of azonal communities along shortdistance gradients results in the organisation of community-complexes and landscape mosaics connected by habitat ecotones characterised by overlap of several faunal types, like Mediterranean, Balkanic, Siberian, Ponto-Caspian, Ponto-Pannonian, Turano-Eremic and Xeromontane elements in the Pannonian forest-steppe complexes. For some invertebrate groups, such as the land gastropods or some soil arthropods, the Carpathian basin contains a considerable proportion of endemic species. The eastern and southern Carpathians, together with the mountains of western Transsylvania, can be considered as core areas of survival and autochtonous evolution in some invertebrate groups with limited mobility. In mobile insect groups only peripherically isolated sibling (sub)species have evolved, which display manifold biogeographic connections, for instance to the Balkan peninsula, Asia minor or southern Russia. The distribution of Mediterranean-Manchurian bicentric faunal elements, connected to the Ponto-Caspian waterwaysystem, shows long-distance disjunctions from the eastern Asiatic taxa. Gallery forests of the Illyrian and Pannonian types and wetlands accompanying the large rivers of the Pannonian lowland have served as corridors of the northward expansion of these species. The post-glacial repopulation of the Carpathian basin from different directions has been supported by Illyrian versus Dacian vicarious pairs of sister (sub)species. Cases of vicarious \xe2\x80\x98Siberian\xe2\x80\x99- Mediterranean sibling taxa have also been established. Recent results confirm that the montane part of the range of several \xe2\x80\x98Siberian\xe2\x80\x99 boreo-montane species does not have its origin in post-glacial \xe2\x80\x98Siberian\xe2\x80\x99 invasion. Populations of some butterfly species have been studied in different geographical scales. Patterns of metapopulation structure and of genetic differentiation have been established.

    Description: Biogeography and ecology of southern Portuguese butterflies and burnets (Lepidoptera) \nDuring several visits to the western part of the Algarve (southern Portugal), the author mapped the butterflies and burnets of this region. In total, I observed 58 butterfly species (51 Papilionoidea, 7 Hesperiidae) and 6 Zygaenidae during my observations in spring and summer. More than 80% of the species are Palaearctic faunal elements, three species are considered Holarctic, three are Nearctic and four are Palaeotropic. Around 75% of the Palaearctic species are Mediterranean faunal elements. Within the Palaearctic group, the 23 species belonging uniquely to the Atlanto- Mediterranean faunal type are by far the largest group. Siberian elements are lacking. Thus, the observed species composition is characteristic for the Atlanto-Mediterranean region. Some of the observed species can be found all over the study area, often in a variety of habitats. Other species are more or less geographically restricted. Their regional distribution patterns depend on geomorphological and ecological constraints. Several species are restricted to the limestone areas, others are limited to the acid schist and granite areas. Several species were only observed in the western coastal dunes. Some species occur exclusively in the mountain areas. Some species were not recorded along the windy western and south-western coastal areas. Several species become rare or even disappear in suitable habitats that show little diversity of the vegetation. The occurrence of many species is directly linked to one or few distinct types of vegetation like cork oak forests, deciduous forests and natural hedges along water courses, Cistus macchias, garigues on limestone, dry grasslands or hot rocky places with little vegetation.

    Description: The apparent influence of climatic change on recent changes of range by European insects (Lepidoptera, Orthoptera) \nFor several years I have been collecting data concerning changes in the ranges of European insects, especially Lepidoptera and Orthoptera. The vast majority of those species which have altered their ranges since 1850 have spread to the north, north-west or west (e.g. 96% of the Lepidoptera expanding their ranges). Of the smaller number of species where the range has contracted, the majority (e.g. 75% of the Lepidoptera) have retreated southwards, south-westwards or south-eastwards. I have attempted to correlate these range changes with the main climatic fluctuations from 1850 to the present. Throughout this long period of predominately warming climate in Europe, those insect species which have been expanding their ranges have done so in steadily increasing numbers, especially since 1975, thus coinciding with the marked increase in temperatures worldwide associated with the anthropogenic greenhouse effect.

    Description / Table of Contents: Résumé En chromatographie liqudde à haute performance (HPLC) à détection par fluorescence, 4 composés ptéridiniques: la xanthoptérine, l'isoxanthoptérine, la 6-bioptérine et la ptérine ont été décelés dans les têtes de P. scutigera Holdaway (Lep. Gelechiidae) adultes. Un autre composé, dénommé ‘xanthoptérine modifiée’, a été décelé aussi dans les têtes de papillons; de même l'isoxanthoptérine a été décelée dans les thorax et abdomens. Les concentrations de ces ptérines ont été dosées dans les têtes des papillons de 2 à 50 jours au laboratoire à 25°C. Les concentrations d'isoxatthoptérine ont été dosées dans les thorax et les abdomens de 2 à 40 jours. La xanthoptérine de la ‘xanthoptérine modifiée’ diminuent nettement avec l'âge, tandis que la ptérine diminue plus lentement et que la 6-bioptérine se maintient pratiquement sans changements. L'isoxanthoptérine diminue dans les têtes de mâles de 38,3 ng/tête à 2 j à 22,7 ng/tête à 50 j, mais chez les femelles les concentrations augmentent nettement de 41,2 ng/tête à 2 j à 150,4 ng/tête à 50 j. Des modifications de même type ont été observées dans les thorax et les abdomens des mâles et des femelles. Les modifications de concentration de la ‘xanthoptérine modifiée’ des têtes de papillons peuvent être utilisées pour évaluer l'âge physiologique de mâles et des femelles de P. scutigera. La confiance dans ces estimations peut être améliorée en se référant aux concentrations d'isoxanthoptérine dans les thorax des mâles et au rapport isoxanthoptérine/‘xanthoptérine modifiée’ dans les têtes de femelles.
    Notes: Abstract The amounts of four pteridine compounds, xanthopterin, isoxanthopterin, 6-biopterin and pterin and a further unidentified substance, termed ‘modified xanthopterin’, were determined in the heads of adult Pectinophora scutigera (Holdaway) (Lepidoptera: Gelechiidae), aged between 2 and 50 days and reared in the laboratory at 25°C. The level of isoxanthopterin was also determined in the thoraces and abdomens of moths aged between 2 and 40 days. The levels of xanthopterin, and ‘modified xanthopterin’ decreased markedly in the heads of males and females with increasing moth age, while those of pterin decreased more slowly and 6-biopterin remained largely unchanged. Isoxanthopterin decreased in male heads from 38.3 ng/head at 2 days to 22.7 ng/head at 50 days, but in females levels increased from 41.2 ng/head at 2 days to 150.4 ng/head at 50 days. Similar changes in the amounts of isoxanthopterin with increasing moth age were observed in male and female thoraces and abdomens. The results are discussed in relation to using pteridine compounds for estimating the physiological age of P. scutigera.

    Notes: Abstract Substrates contaminated by wandering fifth instar larvae ofPlodia interpunctella (Hübner) (Lepidoptera: Pyralidae) elicit oviposition by conspecific female moths, and larval rearing diet enhances oviposition and also induces upwind flight. Two-choice oviposition assays determined that four-day-old gravid femaleP. interpunctella preferred to lay eggs on dishes containing cornmeal-based rearing diet compared to empty dishes. Pieces of cheesecloth contaminated by fifth instar larvae elicited more oviposition than untreated cheesecloth or dishes with food. The combination of larval contamination and food was preferred over food only or larval contamination only in both two- and four-choice experiments. The factor(s) in larval contamination responsible for eliciting oviposition in female moths was extracted in hexane, confirming that organic semiochemicals are responsible for the effect. The oviposition-eliciting activity of larval contamination was retained on cheesecloth for up to 30 days following treatment with larvae, suggesting the active component(s) is stable and of low relative volatility. In two-choice windtunnel bioassays female moths initiated flight only when rearing food was present in one of the treatments, and they displayed the highest landing responses to a combination of larval contamination and food. Earlier work onP. interpunctella and related pyralid species found that larval contamination due to secretions from the mandibular glands acted as both a spacing pheromone for wandering larvae and as a kairomone for host-seeking parasitoid wasps. The present study suggests that the same or a similar secretion acts as an oviposition-eliciting pheromone for conspecific females.
