As an alternative to laboratory rearing of X. glabratus, we developed a simple method for field collection of dispersing females using freshly-cut host wood as bait. Female X. glabratus collected with this method are behaviorally and physiologically in host-seeking mode, ideally suited for evaluation of host-based attractants in controlled laboratory tests.10aXyleborus glabratus1 aKendra, Paul, E.1 aMontgomery, Wayne, S.1 aSanchez, Jorge, S.1 aDeyrup, Mark, A.1 aNiogret, Jerome1 aEpsky, Nancy, D.  uhttps://weevil.myspecies.info/method-collection-live-redbay-ambrosia-beetles-xyleborus-glabratus-coleoptera-curculionidae-scolytin02369nas a2200193   4500008004100000020001400041245010800055210006900163260000800232300000900240490000700249520168000256653003001936100001901966700001901985700001802004700002102022856013202043       2012                        eng d  a0015-404000aANTENNAL SENSILLA OF PARTHENOGENETIC AND BISEXUAL LISSORHOPTRUS ORYZOPHILUS (COLEOPTERA: CURCULIONIDAE)0 aANTENNAL SENSILLA OF PARTHENOGENETIC AND BISEXUAL LISSORHOPTRUS   cMar  a8-150 v953 aAntennal sensilla were compared in parthenogenetic females and bisexual adults of rice water weevil, Lissorhoptrus oryzophilus Kuschel (Coleoptera: Curculionidae), using scanning electron micrographs. The antenna of parthenogenetic females and of both sexes of bisexual reproductive weevils consisted of the scape, pedicel, and 6 flagellar segments. Females, regardless of mode of reproduction, had longer antennal segments than males. The 3 adult forms/genders can be correctly classified into their respective groups with a set of discriminant mathematical functions based on 4 morphological measurements of length or maximum width of segments of the antennae. For both sexes, 6 morphological sensilla types were found on the antennae, including hydrofuge scales I (hsI), trichoid sensilla (ts), 2 types of squamiform sensilla (ssI, ssII), tuft hairs (th), and Bohm bristles (Bb). No remarkable sexual differences in the types or distribution of sensilla were found on the antennae among parthenogenetic and both sexes of bisexual reproductive weevils, except for hsI. Both the length and basal diameter of hsI of females were significantly greater than those of the males. The hsI of the parthenogenetic females were significantly longer than those of the bisexual females. The numbers of branches of hsI on the sixth flagellum of the parthenogenetic females were significantly more than on both sexes of bisexual adults. The numbers of branches of hsI of the females were significantly more than those of the males. From the information gained from this scanning electronic microscope study of antennae, we can separate rice water weevils by gender and reproductive mode.10aLissorhoptrus oryzophilus1 aKang, Gui-Juan1 aZhu, Zeng-Rong1 aCheng, Jia-An1 aWay, Michael, O.  uhttps://weevil.myspecies.info/antennal-sensilla-parthenogenetic-and-bisexual-lissorhoptrus-oryzophilus-coleoptera-curculionidae00987nas a2200157   4500008004100000020001400041245006800055210006500123260000900188300001200197490000700209520047200216653002800688100002100716856009200737       2012                        eng d  a0015-404000aNEW DATA ON CONORHYNCHUS HOLOLEUCUS (COLEOPTERA: CURCULIONIDAE)0 aNEW DATA ON CONORHYNCHUS HOLOLEUCUS COLEOPTERA CURCULIONIDAE  cJune  a503-5050 v953 aLarvae of Conorhynchus hololeucus (Coleoptera: Curculionidae: Lixinae) construct a trehalalike capsule for the immature stages. The host plant is Atriplex sp. (Caryophyllales: Amaranthaceae), and this weevil species is a new record for Turkey. Adults feed on leaves; females lay eggs in root neck of host plants; larvae make an external trehala-like capsule on the root; pupation and adult emergence occur in the capsule.

Beetle captures from Harrison County,Mississippi represent the western-most detection of X. glabratus in North America. These beetles are disjunct from X.glabratus populations occurring along the Atlanticcoast. This broad division between the two populations of X. glabratus has yet to be explained, and phylogeographic testing is underway to determine if a separate introduction from Asia into Mississippi has occurred.10aXyleborus glabratus1 aFormby, John, P.1 aSchiefer, Terence, L.1 aRiggins, John, J.  uhttps://weevil.myspecies.info/first-records-xyleborus-glabratus-coleoptera-curculionidae-alabama-and-harrison-county-mississippi01948nas a2200157   4500008004100000020001400041245013100055210006900186260000900255300001200264490000700276520132500283653003001608100001701638856013501655       2012                        eng d  a0015-404000aOCCURRENCE AND ABUNDANCE OF LISSORHOPTRUS ORYZOPHILUS (COLEOPTERA: CURCULIONIDAE) RELATIVE TO FIELD BORDERS IN CALIFORNIA RICE0 aOCCURRENCE AND ABUNDANCE OF LISSORHOPTRUS ORYZOPHILUS COLEOPTERA  cJune  a445-4530 v953 aField experiments were conducted during 2009 and 2010 on commercial rice fields in the Sacramento Valley of California to validate observations regarding the prevalence of immature populations of the rice water weevil, Lissorhoptrus oryzophilus Kuschel (Coleoptera: Curculionidae), near field borders, and to assess their impact on yield. In 5 commercial fields, insecticide-treated and untreated plots were established 4.5, 30 and 60 m from one edge of the field. Soil core samples were collected on 2 dates and inspected for L. oryzophilus immatures. Rice yields were determined by harvesting 15 m2 plots in 2009 or 1 m2 per plot in 2010. Analysis of variance (ANOVA) showed that in most locations, immature populations were higher in plots 4.5 or 30 m from the field's edge than in plots 60 m from the field's edge. Yields from treated and untreated plots did not differ significantly Linear regression of immature populations and rice grain yield per plot per location did not yield a significant, inverse density-yield relationship. Results indicate that border applications of insecticides for L. oryzophilus management are appropriate; however, growers are advised to inspect their fields to confirm border populations and effects on yield. Research needs regarding sampling and economic thresholds are discussed.10aLissorhoptrus oryzophilus1 aEspino, Luis  uhttps://weevil.myspecies.info/occurrence-and-abundance-lissorhoptrus-oryzophilus-coleoptera-curculionidae-relative-field-borders-c
