TaxID: 249532
Basic Information
Icerya purchasi
Australian fluted scale, Cottony Cushion Scale
Icerya purchasi (common name: cottony cushion scale) is a scale insect that feeds on more than 80 families of woody plants, most notably on Citrus and Pittosporum. Originally described in 1878 from specimens collected in New Zealand as pests of kangaroo acacia and named by W.M. Maskell "after the Rev. Dr. Purchas who, [he] believe[d], first found it", it is now found worldwide where citrus crops are grown. The cottony cushion scale originates from Australia.

Morphological Features
Adult female: body dorsum sparsely covered in waxy secretion with a medial ridge of wax and segmental waxy tufts projecting from the ventral margin around the body. Dorsal surface with dark hair-like setae in dense clusters, also clustered with open-centre pores around the margin. Open-centre pores each 16–18 µm in diameter, 15–17 µm long, with 6–8 outer loculi, present in marginal clusters and densely dispersed across dorsal head. Simple multilocular pores, each 9–10 µm in diameter, with bilocular centre (appearing reniform) and 4 or 5 outer loculi, scattered on ventromedial head and thorax and across ventromedial to submedial abdomen. Cicatrices round to oval, numbering 3, central cicatrix largest or all subequal in size. Anal opening surrounded by long, robust hair-like setae.

PRJNA295742 SRX1277815 SRP064051 insect Transcriptome of Icerya purchasi "Construction of libraries and sequencing on the Illumina HiSeq2500 were performed at the W. M. Keck Center for Comparative and Functional Genomics at the University of Illinois at Urbana-Champaign. Messenger RNA was selected from one microgram of high quality total RNA. RNAseq libraries were constructed using the TruSeq Stranded RNA Sample Preparation Kit (Illumina, San Diego, CA). Libraries were sequenced on an Illumina HiSeq2500 with TruSeq SBS sequencing kits version 4. The libraries were sequenced from both ends of the molecules to a total read length of 100nt from each end. The raw .bcl files were converted into demultiplexed fastq files with Casava 1.8.2 (Illumina)." {'host': 'Pittosporum tobira', 'breed': 'wildtype', 'tissue': 'whole insect', 'collected_by': 'Nate Hardy', 'geo_loc_name': 'USA: AL, Auburn', 'biosamplemodel': 'Invertebrate', 'collection_date': '2015-02-09', 'isolation_source': 'wild-caught'} |
