Heritable bacterial endosymbionts can alter the biology of numerous arthropods. They can influence the reproductive outcome of infected hosts, thus affecting the ecology and evolution of various arthropod species. The spruce bark beetle Pityogenes chalcographus (L.) (Coleoptera: Curculionidae: Scolytinae) was reported to express partial, unidirectional crossing incompatibilities among certain European populations. Knowledge on the background of these findings is lacking; however, bacterial endosymbionts have been assumed to manipulate the reproduction of this beetle...

The ambrosia beetle, Xyleborinus saxesenii Ratzeburg (Coleoptera: Curculionidae, Scolytinae), infests physiologically stressed apple and peach trees in Korea. Dispersing females utilize the degradation product ethanol and host-related volatiles to locate and colonize new host trees. We examined the extent to which 12 chemicals emitted from fruit trees act synergistically with ethanol to attract X. saxesenii. The addition of benzaldehyde to ethanol significantly increased beetle attraction, although benzaldehyde was not attractive by itself...

Coffee berry borer (CBB), Hypothenemus hampei (Ferrari) (Coleoptera: Curculionidae: Scolytinae), is the most serious insect pest of coffee worldwide. Green coffee used in blending and roasting is traded between countries and may be subjected to fumigation for disinfestation of CBB. For example, green coffee shipped to Hawaii from the U.S. mainland must be treated with methyl bromide. Irradiation is an alternative disinfestation treatment option. Dose-response tests were conducted with adult beetles to identify a sterilizing dose, followed by large-scale confirmatory tests with adults infesting coffee berries at 100 Gy (measured doses 84-102 Gy)...

The annual bluegrass weevil (ABW), Listronotus maculicollis Kirby, is an economically important pest of short cut turfgrass. Annual bluegrass, Poa annua L., is the most preferred and suitable host for ABW oviposition, larval survival and development. We investigated the involvement of grass volatiles in ABW host plant preference under laboratory and field conditions. First, ovipositional and feeding preferences of ABW adults were studied in a sensory deprivation experiment. Clear evidence of involvement of olfaction in host recognition by ABW was demonstrated...

Naupactus cervinus (Boheman) (Curculionidae, Naupactini) is a parthenogenetic weevil native to the Paranaense Forest which displays high levels of genetic variation. Two divergent clades were identified, one ranging in forest areas (Forest clade), and the other in open vegetation areas (Grassland clade). Both of them have individuals with high levels of heterozygosity in ribosomal sequences. Investigation of intraindividual variation in ITS1 sequences through cloning and posterior sequencing suggested that mating between both groups most likely occurred in the Paranaense Forest after a secondary contact, which led to fixed heterozygotes as a consequence of parthenogenesis...

Biological aspects and demographic parameters of Cephalonomia stephanoderis Betrem (Hymenoptera: Bethylidae) and Prorops nasuta Waterston (Hymenoptera: Bethylidae) parasitoids of the coffee berry borer (CBB), Hypothenemus hampei (Ferrari) (Coleoptera: Curculionidae: Scolytinae) were investigated using diet-reared CBB hosts. Developmental time from eggs to adults, oviposition, and postoviposition period were comparable for both parasitoids. However, P. nasuta had a considerably longer preoviposition and longevity period averaging 17...

Laurel wilt is a disease threatening the avocado industry in Florida. The causative agent of the disease is a fungus vectored by ambrosia beetles that bore into the trees. Until recently, management strategies for the vectors of the laurel wilt fungus relied solely on chemical control and sanitation practices. Beneficial entomopathogenic fungi (EPF) are the most common and prevalent natural enemies of pathogen vectors. Laboratory experiments demonstrated that commercial strains of EPF can increase the mortality of the primary vector, Xyleborus glabratus , and potential alternative vectors, Xylosandrus crassiusculus , Xyleborus volvulus and Xyleborus bispinatus (Coleoptera: Curculionidae: Scolytinae)...

Eudraces barclayi sp. n. is described from South Africa, illustrated and compared with other species of the genus. Echinocnemodes Voss, 1962 is proposed as a new junior synonym of Eudraces Marshall, 1926. Holcolaccus sparsus (Voss, 1959) is proposed as a new combination from Eudraces Marshall, 1926. Eudraces zumpti Voss, 1959 is a new junior synonym of Eremnus angustirostris Marshall, 1937. A lectotype is designated for Eudraces flavirostris Marshall, 1926. A key to the known Eudraces species is given.

Xyleborini currently consists of more than 1168 species in 36 genera, nearly all of which were described in Xyleborus (Hulcr et al. 2015; Smith 2017). The tribe has been the focus of considerable taxonomic attention over the last decade resulting in phylogenetically based revisions and the erection of new genera (e.g. Hulcr et al. 2007, Hulcr and Cognato 2010). However in the Old World these efforts have largely been restricted to faunas of particular countries such as Taiwan (Beaver and Liu 2010), Thailand (Beaver et al...

The Asian ambrosia beetle, Cyclorhipidion fukiense (Eggers) was detected for the first time in North America based on three specimens trapped in 2012 from three localities in South Carolina and two other specimens intercepted at the port of Savannah, Georgia, in 2010. The species is characterized, illustrated with high-resolution images, and compared with two other congeneric, adventive species (C. bodoanum and C. pelliculosum) presently established in eastern North America. Morphometric measurements are provided and a provisional key is presented to the species of Cyclorhipidion occurring in North America...

The fauna of weevils Curculionoidea of Ukraine numbers 1453 species equivalent to 25.3% of European fauna. They belong to 10 families and 364 genera. A total of 51 species are recorded from Ukraine for the first time. Assessment of inventory completeness indicates that 62% of the area of Ukraine are covered by samples. Spatial join analysis has reveals strong collecting biases and shows maximal richness in cells which fall into well-sampled provinces. A total of 22 out of 33 studied model sites are well-sampled (C>0...

The Chinese species of Cleopomiarus Pierce, 1919 (Curculionidae, Curculioninae, Mecinini) are revised. Six taxa are reported: two already know from China (C. distinctus (Boheman, 1845), C. vestitus (Roelofs, 1875)), two cited for the first time from this country (C. flavoscutellatus (Morimoto, 1959), C. graminis (Gyllenhal, 1813)), and two new to science (C. danfengensis Jiang Caldara n. sp., C. nuerhachii Jiang Caldara n. sp.). The following new synonymy is proposed: C. distinctus (Boheman, 1845) = Miarus longirostris mandschuricus Voss, 1952 n...

Following recent taxonomic study, Macrorhyncolus spinosus sp. nov. is described from China. Earlier, Macrorhyncolus included four species, M. crassiusculus, M. crassitarsis, M. littoralis and M. ventilaginis. A key is presented to all known species of Macrorhyncolus in the Palaearctic Region and China. Illustrations of diagnostic characters of the new species are provided. Macrorhyncolus spinosus is winged, has larger eyes, the rostrum is longer than wide and has a median furrow in the basal half, extending to the vertex, and striae 9 and 10 remain separate from base to apex...

The twig beetle, Pityophthorus pulchellus tuberculatus Eichhoff, infests dead branches of pines in western United States and Canada, including lodgepole pine, Pinus contorta Douglas, in northern Idaho. Adult broods overwintered in their host and emerged and colonized new hosts in late April. Males initiated galleries and were joined by up to seven females, each of which constructed an egg gallery radiating from a central chamber. Galleries had an average of 4.7 egg niches each with an egg that was large relative to the mother beetle...

Recent flight intercept trapping in Gabon provided four female specimens of a new species of Scolytoplatypus Schaufuss with several unusual features. It is the smallest known Afrotropical species found to date (1.6 mm long), it has unusually long antennal clubs, and some characters show resemblance to small Asian species or to the Malagasy genus Remansus Jordal. Genetic data from four genes nevertheless place this species as the sister lineage to all other Afrotropical species where it forms an isolated position corresponding to deviant morphological features...
