Based on material from the Russian Far East, four new genera, Glomepidosis gen.n., Recessepidosis gen.n., Ancorepidosis gen.n. and Zephyrepidosis gen.n. closely related to the genus Monepidosis are described. Seven new species: Monepidosis laccata sp.n., M. yukawai sp.n., Dendrepidosis obstipa sp.n., Pseudepidosis dives sp.n., Glomepidosis solida sp.n., Recessepidosis umbonis sp.n., Ancorepidosis electa sp.n. Dendrepidosis pilifera (Fedotova et Sidorenko, 2005, comb.n.) transferred to the genus Zephyrepidosis gen.n., while Monepidosis munita (Fedotova et Sidorenko, 2005, comb.n.) - to the genus Stomatocolpodia (Avicolpodia subgen.n.). Key to the genera related to Monepidosis and key to the species of the genera Monepidosis Mamaev, Pseudepidosis Mamaev, Dendrepidosis Mamaev, Stomatocolpodia Mamaev are given.

Nine species of the gall midge genus Seriphidomyia (subgenera Seriphidomyia s. str. and Polynomyia) are described. These gall midges develop in bud and leaf galls on wormwoods of the subgenera Seriphidium and Artemisia. Data on the biology and distribution of new species are given. Of four new species of the nominotypical subgenus developing on wormwoods of the subgenus Seriphidium, three species develop in multi-chambered packed apical galls. One species, S. (s. str.) bekoviczi sp. n. is an exception, forming characteristic thin-walled closed galls with elongate apex. Of 5 new species of the subgenus Polynomyia, the majority develop on wormwoods of the subgenus Artemisia, but S. (P.) bajansulu sp. n. develops on Artemisia sublessingiana (subgenusSeriphidium), forming conical leaf galls. No galls of this kind have ever been reported from Seriphidium. At the same time, multi-chambered packed apical galls are never formed on Artemisia; however, the 2 species described below are an exception: S. (P.) przhevalskii sp. n. and S. (P.) valichanovi sp. n.

A survey of Mikania glomerata Sprengel (Eupatorieae: Asteraceae) in southeastern Brazil resulted in the discovery of eight kinds of galls made by eight species of gall midges. All of the galls and their gall makers are described. Seven of the gall makers are new to science and two new genera, Liodiplosis Gagne and Mikaniadiplosis Gagne, are described to contain four of the seven new species. The eight gall-making species are: Alycaulus globulus Gagne, Asphondylia glomeratae Gagne, Asphondylia moehni Skuhrava, Liodiplosis cylindrica Gagne, Liodiplosis conica Gagne, Liodiplosis spherica Gagne, Mikaniadiplosis annulipes Gagne, and Perasphondylia mikaniae Gagne. In addition, another gall midge new to science, Contarinia ubiquita Gagne, is described that lives gregariously in the galls of five of the eight kinds of galls described.

Dasineura tomentosa is a gall midge inducing distinctive galls on Leptospermum laevigatum. An efficient way of determining the geographic distribution of a gall midge is to examine herbarium specimens for the presence of galls inadvertently collected with the plant specimen. Of the 446 herbarium specimens of L. laevigatum examined 40 had galls caused by D. tomentosa, and two of the three galls examined in detail contained a parasitoid wasp. Despite some limitations, herbarium collections are an invaluable resource for insect taxonomists.

Six new species of gall midges are described from the salt marsh plant Suaeda monoica Gmelin in Israel, the first cecidomyiid species to be described from this host. Five of the new species, Baldratia occulta, n. sp., Izeniola obesula, n. sp., Stefaniola siliqua, n. sp., S. defoliata, n. sp,, and S. rufa n. sp., are leaf or twig gallers belonging to a large group of Old World Lasiopterini which is restricted to Chenopodiaceae. Asphondylia acinata, n. sp., is a fruit galler belonging to the Asphondyliini. Descriptions of adults, galls, and larval stages, as available, as well as biological remarks are given for each species. The terminology of female genitalia in the Lasiopterini and the significance of characters of immature stages in this tribe are discussed.

Chilophaga tripsaci (Felt) was recently discovered damaging maize, Zea mays L., in western Mexico. The species was previously known only from a collection made in 1909 on Tripsacum dactyloides (L.) L., eastern gamagrass, in Plano, Texas. Chilophaga Gagne and C. tripsaci are redescribed and a lectotype is designated for the species. It is distinguished from its five congeners by female and larval characters that are illustrated and included in a key to species.

The new genus Afrolasioptera Dorchin is established for a new gall-midge species, A. tumida Dorchin (Diptera: Cecidomyiidae: Lasiopterini), described from bud galls on Elytropappus rhinocerotis (Asteraceae) in the Western and Northern Cape provinces of South Africa. The new genus is unique for the largely inflated segment 8 of the female abdomen and the laterally flattened and conspicuously setose ovipositor. The species is univoltine and induces common galls in shoot tips, often developing in smallgroups. This is the fifth species of gall midge to be described from Asteraceae hosts in southern Africa, a region whose rich cecidomyiid fauna is still largely unknown.

For the identification of host and occurrence of Rice Gall Midge in direct sown rice as well as transplanted rice,the field has been selected for this case study at research farm of Birsa Agricultural University, Kanke, Ranchi. Three grasses Eleusine indica, Bothriochloa sp. and Paspalum sp. have been recorded as alternative host of rice gall midge. Highest infestation was observed on Eleusine indica in second week of July. Seasonal occurrence of Orseolia oryzae W.M. on Kharif rice shoived that pest infestation started in second week of August and continued upto last week of October, the peak activity was observedin last week of September. Parasite activity of Platygaster oryzae was started in the last week of August, at the minimum host infestation of 2.0%. The peak activity occurred during second week of October, consequently heavy (42%) mortality of gall midgedue to this natural enemy was observed during this month.
