The resistance of hazelnut varieties to the nut weevil is known but poorly investigated so far. Thus a 2-year study was carried out to investigate factors affecting C. nucum attacks on two cultivars (Tonda Gentile delle Langhe (TGL), Ennis) and four selections (Daria, 101, B6, L35) in a 15-year-old orchard of northwestern Italy. Nut developmental stages and shell characteristics, such as hardness and thickness, were measured and correlated to the biological cycle of the nut weevil and to the damage by its larvae. During the 2-year sampling, nut weevil adults were collected on all cultivars and selections, but in greater quantities on TGL and Daria, and in lower quantities on 101 and B6. In 2005, by female dissection, mature eggs were observed from late June, when the mean temperature exceeded 18[degree]C. Differences between cultivars and selections were found in nut and kernel development, and in shell hardening; in particular, the kernel development was directly related with the shell hardness. At harvest, the damage varied on average from 2.57% in cultivar TGL to 51.84% in selection 101 of total nuts harvested, so independently of the numbers of the collected weevil adults. These two varieties were the earliest and the latest in kernel development and shell hardening, respectively. Therefore, the susceptibility to nut weevil attacks was strictly related to shell hardening; in fact, a rapid hardening of the shell can hamper the oviposition of C. nucum females. By contrast, no correlation was found between shell thickness and damage at harvest.10aCurculio nucum1 aGuidone, L.1 aValentini, N.1 aRolle, L.1 aMe, G.1 aTavella, L.  uhttps://weevil.myspecies.info/early-nut-development-resistance-factor-attacks-curculio-nucum-coleoptera-curculionidae01301nas a2200169   4500008004100000020001400041245010100055210006900156260000900225300001000234490000900244520069700253653002200950100001800972700002600990856011501016       2007                        eng d  a0350-175200aA contribution to the study of acorn weevil Curculio glandium Marsh.

Among the insects feeding on acorn, the greatest pest is oak weevil, Curculio glandium. This species has been insufficiently researched in Serbia, especially as the pest of common oak acorn, so it is necessary to study in greater detail its main morphological features and the most important elements of its life cycle. The research was performed in a common oak seed orchard at the locality Banov Brod in FE Sremska Mitrovica and by growing in laboratory conditions. This paper presents the results of the study of morphological characters of different development stages of oak weevil, as well as of its life cycle.10aCurculio glandium1 aDrekic, Milan1 aMihajlovic, Ljubodrag  uhttps://weevil.myspecies.info/contribution-study-acorn-weevil-curculio-glandium-marsh-coleoptera-curculionidae02069nas a2200169   4500008004100000020001400041245012200055210006900177260001000246300001200256490000800268520143200276653001801708100001901726700001901745856013501764       2007                        eng d  a0013-874600aCommunity associates of an exotic gallmaker, Dryocosmus kuriphilus (Hymenoptera: Cynipidae), in eastern North America0 aCommunity associates of an exotic gallmaker Dryocosmus kuriphilu  cMarch  a236-2440 v1003 aDr-yocosmus kuriphilus Yasumatsu (Hymenoptera: Cynipidae) is a potentially devastating exotic invasive gall wasp that is rapidly spreading throughout the eastern United States, and infests all species of chestnut, Castanea spp. We investigated the community associates of D. kuriphilus in three geographic locations: Meadowview, VA, Bowling Green, KY, and Broadview Heights, OH. Dissection of galls and observation of chamber contents revealed that gall wasp larval mortality is approaching 47%, and parasitism accounts for nearly 70% of the mortality. Six parasitoid wasp species emerged from chestnut galls, including one introduced species and five of unknown origin. The life histories of each parasitoid and their potential roles within the D. kwiphilus community complex are discussed. Investigation of parasitoid interactions revealed a negative correlation between certain parasitoids, suggesting competition for resources, hyperparasitism, or both. The small chestnut weevil, Curculio sayi (Gyllenhal) (Coleoptera: Curculionidae), caused external damage to galls. Galls also were readily attacked by an unknown fungal pathogen resulting in gall wasp larval mortality. This study is the first to investigate the community associates of D. kuriphilus in North America. Our results have beneficial implications for commercial chestnut production, blight resistance breeding programs, and restoration of American chestnut.10aCurculio sayi1 aCooper, W., R.1 aRieske, L., K.  uhttps://weevil.myspecies.info/community-associates-exotic-gallmaker-dryocosmus-kuriphilus-hymenoptera-cynipidae-eastern-north-amer01567nas a2200169   4500008004100000020001400041245018500055210006900240260001400309300001000323490000700333520085200340653002601192100002101218700002301239856013501262       2007                        eng d  a0022-201100aSusceptibility of the filbertworm (Cydia latiferreana, Lepidoptera: Tortricidae) and filbert weevil (Curculio occidentalis, Coleoptera: Curculionidae) to entomopathogenic nematodes0 aSusceptibility of the filbertworm Cydia latiferreana Lepidoptera  cSeptember  a93-960 v963 aThe objective of this study was to determine the susceptibility of the two primary direct insect pests of hazelnuts in Oregon to three species of entomopathogenic nematodes. The entomopathogenic nematodes (Heterorhabditis marelatus Pt. Reyes, Steinernema carpocapsae All and Steinernema kraussei L137) were used in laboratory soil bioassays to determine their virulence against filbertworm, Cydia latiferreana (Walsingham) (Lepidoptera: Tortricidae) and filbert weevil, Curculio occidentalis (Casey) (Coleoptera: Curculionidae). All three nematode species were infective in laboratory bioassays. Infectivity ranged from 73-100%) and 23-85%, for filbertworm and filbert weevil, respectively. Field results were similar to those found in the laboratory with filbertworm larvae being more susceptible to nematode infection.

Several years' investigation confirmed occurrence of many flea and weevil beetle species that are rare in the Czech Republic (Comasinus setiger (Beck, 1817), Doydirhynchus austriacus (Olivier, 1807), Neophytobius quadrinodosus (Gyllenhal, 1813)), species living in the warm oakwoods (Curculio pellitus (Boheman, 1843), Lasiorhynchites cavifrons (Gyllenhal, 1833)) and species that occur here in the only locality in the northern Moravia (Sciaphobus scitulus (Germar, 1824), Dibolia foersteri Bach, 1859, some Apion spp.). Confirmation of 44 species of the Apion genus (35% of the known Czech species) is the evidence of a great plant diversity in the locality. Kamenna is probably also the overwintering place for some wetland species - e.g. relative rare weevil species Thamiocolus viduatus (Gyllenhal, 1813) or very rare flea species in the Czech Republic - Phyllotreta diademata Foudras, 1859. There were confirmed also two of the expanding weevil species - Larinodontes sturnus (Schaller, 1783) and Miarus distinctus (Boheman, 1845) in the locality.10aCurculio pellitus10aDoydirhynchus austriacus10aLasiorhynchites cavifrons10aNeophytobius quadrinodosus1 aBoza, Petr  uhttps://weevil.myspecies.info/flea-beetles-coleoptera-chrysomelidae-alticinae-and-weevil-beetles-coleoptera-curculionidae-natural02738nas a2200181   4500008004100000020001400041245010300055210006900158260000900227300001200236490000700248520210700255653002102362100001602383700001902399700001602418856012202434       2007                        eng d  a0269-765300aSatiation of predispersal seed predators: the importance of considering both plant and seed levels0 aSatiation of predispersal seed predators the importance of consi  cJune  a367-3800 v213 aPlants can redeuce the fitness costs of granivory by satiating seed predators. The most common satiation mechanism is the production of large crops, which ensures that a proportion of the seeds survive predation. Nevertheless, satiation of small granivores at the seed level may also exist. Larger seeds would satiate more efficiently, enhancing the probability of seed survival after having been attacked. However, a larger seed size could compromise the efficiency of satiation by means of large crops if there were a negative relationship between seed size and the number of seeds produced by an individual plant. We analyze both types of satiation in the interaction between the holm oak Quercus ilex and the chestnut weevil Curculio elephas. Both crop size and acorn size differed strongly in a sample of 32 trees. Larger crop sizes satiated weevils, and higher proportions of the seeds were not attacked as crop size increased. Larger seeds also satiated weevil larvae, as a larger acorn size increased the likelihood of embryo survival. Seedling size was strongly related to acorn size and was reduced by weevil attack, but seedlings coming from large weeviled acorns were still larger. The number and the size of the acorns produced by individual trees were negatively related. Larger proportions of the crop were infested in oaks producing less numerous crops of larger acorns. However, contrary to expectations, these trees did not satiate more effectively at the seed level either. Effective satiation by larger acorns was precluded by larger multi-infestation rates associated to smaller seed crops, in such a way that the proportion of attacked seeds that survived did not vary among trees with different acorn sizes. These results highlight the need of considering satiation by means of large crops and large seeds in studies of predispersal seed predation. Long-term monitoring on individual oaks will help to assess whether there is a trade-off between the number and the size of the acorns and, if it existed, how it could condition the fitness consequences of both types of satiation.10aCurculio elephas1 aBonal, Raul1 aMunoz, Alberto1 aDiaz, Mario  uhttps://weevil.myspecies.info/satiation-predispersal-seed-predators-importance-considering-both-plant-and-seed-levels
