| transcriptome analysis of the chinese white wax scale ericerus pela with focus on genes involved in wax biosynthesis. | the chinese white wax scale, ericerus pela chavannes is economically significant for its role in wax production. this insect has been bred in china for over a thousand years. the wax secreted by the male scale insect during the second-instar larval stage has been widespread used in wax candle production, wax printing, engraving, chinese medicine, and more recently in the chemical, pharmaceutical, food, and cosmetics industries. however, little is known about the mechanisms responsible for white ... | 2012 | 22536429 |
| characterization and functional assay of a fatty acyl-coa reductase gene in the scale insect, ericerus pela chavannes (hemiptera: coccoidae). | ericerus pela chavannes (hemiptera: coccoidae) is an economically important scale insect because the second instar males secrete a harvestable wax-like substance. in this study, we report the molecular cloning of a fatty acyl-coa reductase gene (epfar) of e. pela. we predicted a 520-aa protein with the far family features from the deduced amino acid sequence. the epfar mrna was expressed in five tested tissues, testis, alimentary canal, fat body, malpighian tubules, and mostly in cuticle. the ep ... | 2017 | 29277917 |
| identification and evaluation of reference genes in the chinese white wax scale insect ericerus pela. | the chinese white wax scale insect, ericerus pela, is a well-known resource insect. the females and males are dramatically distinct at each developmental stage. we sought to identify suitable reference genes to use as internal controls in molecular research on e. plea. | 2016 | 27390632 |
| genetic diversity and variability in populations of the white wax insect ericerus pela, assessed by aflp analysis. | the white wax insect ericerus pela chavannes (hemiptera: coccoidea) is an economically valuable insect species that has been used for over a thousand years in china. the present study focuses on assessing the genetic variability in different populations of e. pela collected from seven chinese provinces. the amplified fragment length polymorphism technique was used to generate dna fingerprints of individuals from each population using nine primer combinations (ecori-msei). a total of 435 polymorp ... | 2015 | 26782427 |
| transcriptomic and proteomic analyses on the supercooling ability and mining of antifreeze proteins of the chinese white wax scale insect. | the chinese white wax scale insect, ericerus pela, can survive at extremely low temperatures, and some overwintering individuals exhibit supercooling at temperatures below -30°c. to investigate the deep supercooling ability of e. pela, transcriptomic and proteomic analyses were performed to delineate the major gene and protein families responsible for the deep supercooling ability of overwintering females. gene ontology (go) classification and kyoto encyclopedia of genes and genomes (kegg) analy ... | 2016 | 26799455 |
| transcriptome analysis of sexually dimorphic chinese white wax scale insects reveals key differences in developmental programs and transcription factor expression. | the chinese white wax scale insect, ericerus pela, represents one of the most dramatic examples of sexual dimorphism in any insect species. in this study, we showed that although e. pela males display complete metamorphosis similar to holometabolous insects, the species forms the sister group to acyrthosiphon pisum and cluster with hemimetabolous insects. the gene expression profile and gene ontology (go) analyses revealed that the two sexes engaged in distinct developmental programs. in particu ... | 2015 | 25634031 |
| [ultrastructure of ericerus pela (chavannes) nymph mouthparts and ecological adaptations]. | the ultrastructure of nymph mouthparts of the chinese white wax scale (cwws), ericerus pela, consists internally of the crumena, tentorium, the stylet bundle, comprised of two mandibular stylets and two maxillary stylets, and the external clypeolabral shield, labium and sensilla. the mouthpart morphology and structures of the female nymphs are similar to the male. the mouthparts of cwws have significantly different features in comparison to aphids and other coccids. first, the mouthparts of cwws ... | 2012 | 23019025 |
| [molecular detection of symbiotic bacteria arsenophonus from ericerus pela chavannes]. | the purpose of this study is to examine the relation between the sex ratio of ericerus pela and its symbiotic bacterial arsenophonus. | 2012 | 23173437 |
| sex differences in piercing-sucking sites on leaves of ligustrum lucidum (oleaceae) infested by the chinese white wax scale insect, ericerus pela (chavannes) (hemiptera: coccidae). | the type of host tissues and cells ingested by piercing and sucking insects greatly affects their nutrient intake, which may subsequently affect insect fitness. this study describes the sex differences in feeding site selection between male and female nymphs of the chinese white wax scale insect (cwws), ericerus pela (chavannes), feeding on leaves of the chinese privet, ligustrum lucidum. our data showed that the stylet tips of female nymphs terminated in the phloem sieve elements of main or lat ... | 2013 | 23949749 |
| cloning and expression analysis of four heat shock protein genes in ericerus pela (homoptera: coccidae). | to explore the function of small heat shock protein genes (shsps) and hsp70 in ericerus pela, we cloned the full-length cdna sequences of hsp21.5, hsp21.7, hsp70, and hsc70 and the genomic sequence of hsc70. open reading frames of the four hsps were 570, 564, 1,908, and 1,962 base pairs (bp), respectively, which encode proteins with calculated molecular mass of 21.5, 21.7, 69.8, and 71.6 kda. amino acid sequence analysis revealed the presence of the conserved hsp motifs in all four proteins. the ... | 2014 | 25826465 |
| protein profiles of chinese white wax scale, ericerus pela, at the male pupal stage by high-throughput proteomics. | the chinese white wax scale insect (ericerus pela) is sexually dimorphic with holometabolous males and hemimetabolous females. holometabolous insects were assumed to originate from hemimetabolous ancestors. therefore, the male pupal stage is a major innovation compared with hemimetabolous female insects. here, the protein profiles of the male pupae were obtained by high-throughput proteomics and analyzed using bioinformatics methods. a total of 1,437 peptides were identified and assigned to 677 ... | 2014 | 25186183 |
