Several thousands of the seven-spot ladybird Coccinella septempunctata L., descended upon a cruise ship over several hours in daylight while in port in Morocco in April 2009. The ship had recently arrived from South America. Despite a treatment of fumigation beetles were found living after fourteen days following the inoculation event. This observation indicates an ocean transmission of large numbers of this species could take place and might have happened in the past.
Many species of carabid beetles are important pre- and post-dispersal seed feeders of herbaceous plants. Here we summarise data from dissections, field observations, rearing and "cafeteria" experiments on 55 granivorous and 188 omnivorous species that occur in Italy. We tested the hypothesis that seed feeding carabids are restricted to taxa with pronounced morphological adaptations for manipulating and crushing seeds in both the larval and adult stages. The feeding guilds of carabids were rearranged into the following groups: (i) strict predators with long mandibles and predaceous larvae, often depending also on non-prey food; (ii) omnivorous species with stout mandibles and larvae of a seed-eating morphotype; (iii) granivorous species, feeding only on seeds with larvae sometimes of the scarabeoid c-form type. The seed feeding carabids in the Italian fauna belong to the tribe Zabrini (Amara and Zabrus genera) and to all the Harpalinae (sub)tribes, from Anisodactylini to Ditomina. The time of reproduction seems to be associated with habitat preference; wetland or dry open land, rather than true granivorous versus omnivorous habits, but in stenophagous seed feeders, a phenological coincidence with particular plants is sometimes recorded., Federica Talarico, Anita Giglio, Roberto Pizzolotto, Pietro Brandmayr., and Obsahuje bibliografii
This article examines the marked decline in Irish social housing’s traditional role as the main source of accommodation for low-income households. We argue that although this policy redirection has become clearly apparent in the context of the Global Financial Crisis; its roots are, in fact, much older. They lie, not in Ireland’s most recent fiscal crisis, but in the last one which occurred between the late 1970s and mid-1980s. Changes made to arrangements for funding social housing during this time effected a long-term contraction in the social housing’s contribution to total housing output which, in turn, precipitated growing reliance on housing allowance subsidised private rented housing to accommodate this group. The post-GFC austerity merely accelerated this long-term trend rather than signalled a new policy direction.
The Japanese species of Asteiidae are revised. Six species of Asteia Meigen, 1830, are recorded here in addition to Astiosoma okinawae Sabrosky, 1957, hitherto recorded from Japan. Among them, Asteia gemina, A. longistylus, A. lunaris, and A. nigrigena are described as new to science. Asteia angustipennis Duda, 1934, and A. megalophthalma Duda, 1927, are recorded from Japan for the first time. There are conspicuous morphological differences in the male and female genitalia of the seven species of Asteia. It is suggested that Asteia angustipennis, A. concinna, and A. gemina are very closely related and may be reproductively isolated because of their body markings and male genitalia. These species are assigned to the concinna group of Asteia, newly designated in this study. A key to Japanese species and distribution maps are provided.
