Two strains of Microctonus aethiopoides with differing host preferences have been released in New Zealand The first was released in 1982 to suppress Sitona discoideus a pest of lucerne and the second was released in 2006 for biological control of Sitona lepidus This paper describes three genetic approaches (esterase isozymes aldehyde oxidase allozymes and nucleotide sequences in a 676 bp region of the mitochondrial cytochrome oxidase subunit one gene) for distinguishing between the M aethiopoides strains A range of research applications for these methods is discussed

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.

The biological control programme against Sitona lepidus (Gyllenhal) (Coleoptera Braconidae) commenced in 1998 with the first parasitised weevils imported into New Zealand quarantine in 2000 Extensive collections in Europe confirmed that the solitary endoparasitoid Microctonus aethiopoides Loan (Hymenoptera Braconidae) was the principal natural enemy of adult S lepidus With one exception all M aethiopoides reared from S lepidus collected in Europe have been arrhenotokous All M aethiopoides collected from Ireland are thelytokous which obviates the risk of hybridisation with an arrhenotokous Moroccan strain already established in New Zealand Levels of parasitism in S lepidus fieldcollected from Ireland were low (lt;8) and overall averaged 07 Rates of parasitism of S lepidus in New Zealand quarantine have averaged 25 but ranged from 0 to 95 Aspects relating to the rearing and management of Irish M aethiopoides are discussed including possible reasons for low rates of parasitism in quarantine

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.
