Neste estudo descrevemos a riqueza de morfotipos galhas induzidas por artrópodes em uma área Floresta Estacional Semidecidual no Rio Grande do Sul, Brasil. Nós encontramos 71 espécies galhadores, maioria delas Cecidomyiidae (Diptera) associada 51 plantas hospedeiras 27 famílias. Asteraceae foi família hospedeira mais representativa (18 morfotipos). A maior parte das induzida ramos (56%) e forma...

A new species, Dasineura camassiae Gagné (Diptera: Cecidomyiidae), is described, illustrated and compared to some of its congeners from related hosts and western North America. The new species causes flower galls on Camassia (Agavoideae; Asparagaceae) in the Pacific Northwest. Its current known distribution is Oregon and Washington, USA. Larvae develop in spring in flowers of Camassia spp., cau...

The cultivation of genetically modified (GM) plants has raised several environmental concerns. One of these concerns regards non-target soil fauna organisms, which play an important role in the decomposition of organic matter and hence are largely exposed to GM plant residues. Soil fauna may be directly affected by transgene products or indirectly by pleiotropic effects such as a modified plant...

The structure-activity relationship of 12 isolated acetylenes from galls of Hedera rhombea (Araliaceae) induced by Asphondylia sp. (Cecidomyiidae) and their derivatives has been studied for the inhibition of the shoot and root growth of rice, perennial ryegrass, cockscomb, lettuce, and cress. Almost all acetylenes generally showed growth inhibitory activity. The diacetylenes exhibited higher ac...

The Israeli fauna of gall midges (Diptera: Cecidomyiidae) associated with plants of the family Apiaceae consists of three species of Lasioptera and two species of Schizomyia that all appear to be monophagous and univoltine. Lasioptera foeniculi n. sp. and Schizomyia botellus n. sp. are described as new to science. Lasioptera carophila, Lasioptera umbelliferarum and Schizomyia buboniae are redes...

We have previously characterized a gene coding for the secreted-salivary-gland-protein 11A1 (SSGP-11A1) from the Hessian fly, Mayetiola destructor (Say) (Diptera Cecidomyiidae). Here we report the cloning and characterization of three new genes coding for proteins designated SSGP-11B1, SSGP-11C1, and SSGP-11C2, and their relationship with the SSGP-11A1-encoding gene. Based on their structural c...

The Swede midge, Contarinia nasturtii Kieffer (Diptera: Cecidomyiidae), a common insect pest in Europe, is a newly invasive pest in North America that constitutes a major threat to cruciferous vegetable and field crops. Since its first identification in Ontario, Canada, in 2000, it has rapidly spread to 65 counties in the provinces of Ontario and Quebec and has recently been found in canola (on...
