After nine months' rearing in eclectors, branches were cut to 20-cm sections, and signs of infestation as well as larvae and adult insects were noted. We analysed 395 sections of branches from Q. pubescens, 125 sections from Q. cerris, and 85 sections from Q. petraea. We found 44 adult insects: 45% were from the Cerambycidae family (Callimus angulatus ssp. angulatus, Poecilium alni, and Exocentrus adspersus), 18% were from the Scolytinae subfamily (Scolytus intricatus, Xyleborus dispar), 4% from the Buprestidae family (Coraebus florentinus), 4.5% from the Cleridae family (Tilloidea unifasciata), and 28.5% from other families. In addition, 145 larvae were found: 50% from the Cerambycidae family, 39% from the Buprestidae family, 4% from the Scolytinae subfamily, and 7% from other families. Significant difference in the abundance of adult insects and larvae with regard to the diameter of branch sections and the host species were found. 78% of dying branches showed signs of infestation. Species of the Buprestidae, Scolytinae, and Cerambycidae represent important factors in the decline in oak vitality in the lower Karst region of Slovenia.10aScolytus intricatus10aXyleborus dispar1 aJurc, Maja1 aBojovic, Srdan1 aKomjanc, Bostjan1 aKrc, Janez  uhttps://weevil.myspecies.info/xylophagous-entomofauna-branches-oaks-quercus-spp-and-its-significance-oak-health-karst-region-slove02301nas a2200181   4500008004100000020001400041245016200055210006900217260001300286300001400299490000700313520157600320653002001896100002201916700002401938700002201962856013501984       2009                        eng d  a0006-308800aDiversity of ophiostomatoid fungi associated with bark beetles (Coleoptera: Scolytidae) colonizing branches of Norway spruce (Picea abies) in southern Poland0 aDiversity of ophiostomatoid fungi associated with bark beetles C  cDecember  a1170-11770 v643 aBark beetles (Coleoptera: Scolytidae) infesting Norway spruce trees are known to be associated with fungi, especially species of Ophiostoma sensu lato and Ceratocystis. However, very little is known about these fungi in Poland. In this study, we examined the ophiostomatoid species associated with seven species of bark beetles developing in Norway spruce (Picea abies). Fungi were isolated from the beetles and their galleries at ten sites in southern Poland. We identified a total of 2,769 fungal isolates that belong to 19 ophiostomatoid species. These 19 species included a total of 16 associations between fungi and bark beetles that had not been previously recorded. The isolated fungal species were similar to those previously reported. The species spectrum and relative abundance of fungal associates were similar in seven bark beetle species, despite some differences between species. Except for Pityophthorus pityographus, all bark beetles species were frequently associated with ophiostomatoid fungi. The most commonly encountered fungal associates of bark beetles were the following: Ophiostoma ainoae, O. bicolor, O. piceae sensu lato and Grosmannia piceiperda. The results support the hypothesis that pathogenic ophiostomatoid fungi are important for aggressive bark beetles to kill trees. The most virulent fungal associate of bark beetles, Ceratocystis polonica was most commonly associated with Ips typographus. The most frequent ophiostomatoid species isolated from the beetles and galleries of P. pityographus were O. ainoae and Graphium fimbriisporum.10aIps typographus1 aJankowiak, Robert1 aKacprzyk, Magdalena1 aMlynarczyk, Marta  uhttps://weevil.myspecies.info/diversity-ophiostomatoid-fungi-associated-bark-beetles-coleoptera-scolytidae-colonizing-branches-nor00423nas a2200121   4500008004500000020001400045245006200059210005900121300000800180490000700188100001700195856008900212       1988                        Engldsh    a0006-308800aColeoptera, Curculionidae, Bagous wagneri Dieckmann, 19640 aColeoptera Curculionidae Bagous wagneri Dieckmann 1964  a1780 v431 aHolecova, M.  uhttps://weevil.myspecies.info/coleoptera-curculionidae-bagous-wagneri-dieckmann-196402124nas a2200169   4500008004500000020001400045245013100059210006900190260000900259300001200268490000700280520146800287653002401755100002301779700001701802856013501819       2008                        Engldsh    a0006-308800aContrast adaptation to time constraints on development of two pre-dispersal predators of dandelion (Taraxacum officinale) seed0 aContrast adaptation to time constraints on development of two pr  cJune  a418-4260 v633 aPre-dispersal seed predators of quickly maturing inflorescences of Asteraceae are constrained by shortage of development time. At seed dispersal, they should pupate or, if still immature, relocate into another inflorescence. To investigate how dominant coleopteran predators of dandelion seed, Glocianus punctiger (Curculionidae) and Olibrus bicolor (Phalacridae), cope with time limitation we combined observation (development and temperature of dandelion capitulum, thermal constants of predator development, age structure of larval populations at seed dispersal) and analogy ("rate isomorphy" in predator development, comparing "model" coleopteran species with similar temperature requirements). Development of a dandelion capitulum takes 21 days. The time available to G. punctiger (140-190 day degrees, development threshold 6.3[degree]C) is sufficient to complete development and pupate after seed dispersal. By contrast, only 30-50 day degrees are available to O. bicolor (threshold 13.5[degree]C) and this is not enough to complete development and consequently immature larvae should move to other capitula to continue feeding until pupation. These contrast strategies which are determined by this thermal adaptation, are accompanied by differences in larval morphology. The "cold adapted" G. punctiger has an apodous larva not capable of migrating between capitula while the "warm adapted" O. bicolor has a mobile campodeiform larva capable of migration.10aGlocianus punctiger1 aMartinkova, Zdenka1 aHonek, Alois  uhttps://weevil.myspecies.info/contrast-adaptation-time-constraints-development-two-pre-dispersal-predators-dandelion-taraxacum-off
