Bhendi Yellow Vein Mosaic Virus (BYVMV) incidence caused by white fly is the main bottleneck for cultivation of the okra. The present investigation was carried out in three major okra-growing districts of Tamil Nadu viz., Coimbatore, Dharmapuri and Dindugul on whitefly incidence and occurence. A field survey on these districts revealed that the mean whitefly population of 1.82 per plant was observed while the incidence of BYVMV in the Coimbatore district was 13 per cent. The least mean population was observed in the Dharmapuri district with a mean of 0.48 whiteflies per plant and BYVMV incidence of 15.75 %. In order to gain insight into whitefly genotypes occurring on Okra (Abelmoschus esculentus L. (Moench), whitefly samples were collected from 8 locations of Tamil Nadu, and their mitochondrial cytochrome oxidase subunit I (mtCOI) gene was molecularly characterized for species identification. sequences results revealed that the whitefly belongs to Asia I genotype. Thus, the present study confirmed the presence of Asia 1 genotype in B. tabaci throughout Tamil Nadu okra growing regions.

Sycanus aurantiacus Ishikawa & Okajima, found in Bali, was first described in 2007 as a new harpactorine species based on morphological and biological characteristics; however, its genome has not yet been sequenced. In this study, we examine the mitochondrial cytochrome oxidase subunit I (MtCOI) nucleotide sequence of S. aurantiacus in order to determine whether it represents a new harpactorine species. A sample from Pancasari, Bali, Indonesia was collected at the same location S. aurantiacus was first discovered in 2007. The selected mtCOI gene (650 bp) was successfully amplified using mtCOI primer pairs LCO1490 and HCO2198, and the resulting MtCOI sequence of the S. aurantiacus sample was compared with those from other hapactorine species recorded in GenBank. This comparison revealed low genetic similarity between S. aurantiacus and most other harpactorine species worldwide, except for the Genus Sycanus (JQ888697) from USA whose mtCOI shares approximately 91% similarity with the Pancasari sample. Phylogenetic analysis indicated a close genetic relationship between Sycanus from Bali and the Genus Sycanus (JQ888697) from the USA. The mtCOI sequence of S. aurantiacus had not been recorded previously, and our comparison with existing Sycanus sequences provides support to the understanding that S. aurantiacus is indeed its own species.

Abstract A male of Chromatomyia aizoon (Hering, 1932) (Diptera: Agromyzidae) was reared from a leaf mine at Saxifraga paniculata collected in Štramberk (Northern Moravia, Czech Republic). Partial sequence of the mitochondrial cytochrome oxidase subunit I (COI barcode region, 658 bp) is also provided.

Sarcophaga Meigen, 1826 is proposed as a senior synonym of Cornexcisia Fan & Kano, 2000, syn. nov. and Fanzideia Xue, Verves & Du, 2011, syn. nov. Cornexcisia Fan & Kano, 2000, stat. rev. is given status as a subgenus and is considered a senior synonym of Fanzideia Xue, Verves & Du, 2011, syn. nov. at the subgeneric level. Cornexcisia is argued to contain S. (Cornexcisia) longicornuta (Fan & Kano, 2000), comb. nov., S. (C.) cygnocerca (Xue, Verves & Du, 2011), comb. nov., S. (C.) kurahashii (Shinonaga & Tumrasvin, 1979), subgen. comb. nov. (from Phallosphaera Rohdendorf) and S. (C.) suthep Pape & Bänziger, 2003, subgen. comb. nov. (from Rosellea Rohdendorf). Sarcophaga (C.) kurahashii is newly recorded from China (Yunnan), the male is redescribed and the female is described for the first time, supported by photographs, illustrations and mitochondrial cytochrome oxidase subunit I (COI) gene sequences. Species of Cornexcisia share an exceptionally long postpedicel in the female and the following apomorphic distiphallic appendages in the male: juxta ventro-proximally with an apically divided arm with cuticular pile, and lateral styli bifurcated from the base with each branch elongate, gently curved and slightly expanded apically. A key to the species of Cornexcisia is provided.

We identified newly discovered pamphiliid larvae feeding on Cornus in Tochigi and Ibaraki Prefectures, Honshu, Japan, with Pamphilius japonicus Shinohara, 1985, by molecular methods using mitochondrial cytochrome oxidase subunit 1 (COI) gene sequences. The host plant of P. japonicus was unknown. This is the first record of the Cornaceae as a host plant of the Pamphiliidae in the Old World. The larvae were solitary leaf-rollers on Cornus and discovered mainly on small young trees in shadowy forests.
