| a molecular phylogeny of hemiptera inferred from mitochondrial genome sequences. | classically, hemiptera is comprised of two suborders: homoptera and heteroptera. homoptera includes cicadomorpha, fulgoromorpha and sternorrhyncha. however, according to previous molecular phylogenetic studies based on 18s rdna, fulgoromorpha has a closer relationship to heteroptera than to other hemipterans, leaving homoptera as paraphyletic. therefore, the position of fulgoromorpha is important for studying phylogenetic structure of hemiptera. we inferred the evolutionary affiliations of twent ... | 2012 | 23144967 |
| an old remedy for a new problem? identification of ooencyrtus kuvanae (hymenoptera: encyrtidae), an egg parasitoid of lycorma delicatula (hemiptera: fulgoridae) in north america. | spotted lanternfly, lycorma delicatula (white) is a recently introduced pest of tree-of-heaven, ailanthus altissima (mill.) swingle in north america. natural enemy surveys for this pest in pennsylvania in 2016 recovered an encyrtid egg parasitoid from both field collections and laboratory rearing of field-collected l. delicatula egg masses. both molecular and morphological data confirm that the egg parasitoids are ooencyrtus kuvanae (howard) (hymenoptera: encyrtidae). ooencyrtus kuvanae (howard) ... | 2017 | 28069731 |
| [separation and preparation of indole alkaloids in lycorma delicatula white. by hplc]. | a hplc method for separating and preparing indole alkaloids is described. hplc conditions for analysis: bio-rad series 700 hplc, model 700 data station, uv: model 1749 uv-vis monitor, column: bio-rad hi-pore rp318, 250 mm x 10 mm, mobile phase: 80% methanol-h2o(gradient), flow rate: 1.5 ml/min, detection wavelength: 254 nm. on the basis of spectral (1hnmr, 13cnmr, h-h cosy, ms, dept) and chemical evidence, the structures of two compounds were elucidated as beta-yohimbine (yohimban-16-carboxylic ... | 1996 | 9772647 |
| adhesive properties of the arolium of a lantern-fly, lycorma delicatula (auchenorrhyncha, fulgoridae). | the arolium in lycorma delicatula is shaped as a truncated pyramid, tapering proximally. the base or the terminal area is corrugated, forming parasagittal wrinkles (period 1.5-5.0 microm), which are supported from inside by cuticular dendrites. side faces of the arolium are made up of sclerotized dorsolateral plates. when claws slip on a smooth substrate and pronate, the dorsolateral plates diverge and expand the sticky terminal area. the real contact area with the glass plate was recognized by ... | 2008 | 18479702 |
| isolation and characterization of eight microsatellite loci from lycorma delicatula (white) (hemiptera: fulgoridae) for population genetic analysis in korea. | lycorma delicatula (white) is native to china but is becoming an important insect pest in korea. polymorphic dna markers like microsatellites are widely used for characterizing dispersal patterns and capacity of invasive insect pests which can contribute to designing effective management of the species. to facilitate such population genetic studies of l. delicatula in korea, we isolated and characterized eight microsatellite loci for l. delicatula using a hybridization-biotin enrichment method. ... | 2012 | 22187348 |
| genetic structure of lycorma delicatula (hemiptera: fulgoridae) populations in korea: implication for invasion processes in heterogeneous landscapes. | lycorma delicatula (white) was identified in 2004 as an invasive pest in south korea, where it causes serious damage to vineyard crops. to investigate the population structure and dispersal pattern of l. delicatula in south korea, we estimated the population genetic structure and gene flow among nine locations across the country using seven microsatellite markers. although l. delicatula spread throughout most of its geographical range in south korea within 5-7 years following invasion, its popul ... | 2013 | 23473368 |
| structure and sensilla of the mouthparts of the spotted lanternfly lycorma delicatula (hemiptera: fulgoromorpha: fulgoridae), a polyphagous invasive planthopper. | mouthparts are among the most important sensory and feeding structures in insects and comparative morphological study may help explain differences in feeding behavior and diet breadth among species. the spotted lanternfly lycorma delicatula (white) (hemiptera: fulgoromorpha: fulgoridae) is a polyphagous agricultural pest originating in china, recently established and becoming widespread in korea, and more recently introduced into eastern north america. it causes severe economic damage by sucking ... | 2016 | 27253390 |
