Member Location: Liege, Belgium Posts: 403 Joined: 05.08.13 @John Carr I collected a 100 ml sample in a puddle on a roof. Previously, Porricondylinaewere treated as one of five subfamilies of the Cecidomyiidae, gall midges, with nearly 620 extant species known worldwide and 24 species recorded in Sweden. The most common prey are aphids and spider mites, followed by scale insects, then other small prey such as whiteflies and thrips, which eat the eggs of other insects or mites. Phytophagous Cecidomyiidae generally have narrow host-plant ranges (Gagné 1986) with more than 90% of them inducing galls on a single host-plant species (Skuhrava et al. (Ed.). The wings are usually clear, rarely patterned. Huang, J., Ruifa Hu, Scott Rozelle, Carl Pray. These tiny insects are prone to lurk in cargoes and spread over long distances. Plants cannot produce enough foliage to support a heavy fruit crop, resulting in smaller berries with lo… Methods of cultural and chemical control are suggested, and the need for further research … This … Wings are covered with long hairs. As the larvae are incapable of moving considerable distances, a substantial population of prey must be present before the adults lay eggs, and the Cecidiomyiidae are most frequently seen during pest outbreaks. Larvae use their strong “jaws” to grasp their prey. The mouthparts are reduced. Recent studies, however, show that the midge feeding on cranberry may be a separate species. This identification was made possible because of a revision of Arthrocnodax in preparation by one of us (RG). They are characterised by hairy wings, unusual in the order Diptera, and have long antennae. The taxonomic status of these genera and their included species is reviewed, and new generic and specific synonymies are given. Kolesik, P.

In these, instead, close to the aedeagus, is a triangular basal outgrowth of the gonocoxites called the gonosterna. Previously unrecorded damage to tomato and cucumber crops grown in glasshouses in Greece is described and attributed to an unidentified species of Lasioptera (Diptera: Cecidomyiidae). Los Baños (Philippines): International Rice Research Institute and Indian Council of Agricultural Research. 1. Cecidomyiidae is a family of flies known as gall midges or gall gnats.

The material examined in the present study is kept in the collection of the Chair of Entomology and Agricultural Zoology, Faculty of Agriculture, University of Belgrade. Debate Over a GM Rice Trial in China. 2005. Their larvae feed in plant tissues, so their infestations are imperceptible until crop damage and economic loss appear. Ocelli are present only in the Lestremiinae. Midges also cause severe damage to vegetative growth. Herbivores: larvae feed on plant tissues. 195 p. Heong, KL, YH Chen, DE Johnson, GC Jahn, M Hossain, RS Hamilton. Proceedings of the International Workshop, 22–24 November 1998, Hyderabad, India. Abstract ...

Gall midges (Diptera, Itonididae) which develop in aphid colonies . We analysed the COI gene of mitochondrial DNA extracted from larvae of Rabdophaga (Diptera: Cecidomyiidae) that induce rosette galls on Salix in the Holarctic Region. Larvae develop in stems, and resulting necrosis induces wilting, stem breakages and reduction of fruit production. Cecidomyiidae Macquart, ... much shorter than second tarsomere except in Lestremiinae.

Other important pests of this family are the wheat blossom midge Sitodiplosis mosellana, the asian rice gall midge (Orseolia oryzae) and the African rice gall midge O. oryzivora. The ovipositor is short, lamelliform, or long, mobile, and in some species, acicular. The larvae have on the ventral side of the prothoracal segment a spatula sternalis, a sclerotised organ, which is unique to the family and important for identification at the specific level. Biological studies on Aphidoletes aphidimyza Rondani (Dip. Ali Gol.

Wheat midge development consists of one generation per year with mature larvae falling from wheat ears to the ground from mid to late May. Learn more. Cecidomyiidae are very fragile small insects usually only 2–3 mm (0.079–0.118 in) in length; many are less than 1 mm (0.039 in) long. Methods of cultural and chemical control are suggested, and the need for further research … The legs are long and slender, without apical bristles. The wing bears microtrichia, often as scales, and some species have macrotrichia. Teil: Porricondylinae und Itonidinae Mitteleuropas. Therefore, in Cecidomyiidae taxonomy, species distinctions are often made on the basis of host association (Gagné 1986).

[5], More than 6,000 species and 783 genera are described worldwide, but since 1,100 are from well-studied North America, this is certainly an underestimate,[6] and a recent DNA barcoding study estimated the fauna of Canada alone to be in excess of 16,000 species, hinting at a staggering global count of over 1 million cecidomyiid species that have yet to be described, which would make it the most speciose single family in the entire animal kingdom.[7]. The midge Contarinia nasturtii Kieffer (Diptera: Cecidomyiidae) was first confirmed in North America in Ontario, Canada, in 2000. instars for future identification. Tibial spurs absent. [8][9], Many species are economically significant, especially the Hessian fly, a wheat pest, as the galls cause severe damage. A. aphidimyza (Rond.

Krishnaiah, [eds]. A major digestive proteinase in the guts of larvae of biotype D of Mayetiola destructor is a chymotrypsin-like serine proteinase which can hydrolyze [3 H]alpha-casein and benzoyl-l-tyrosine ethyl ester (BTEE).Hydrolysis of protein and ester by the gut proteinase were blocked by diisopropyl fluorophosphate (DFP) and inhibited by l-1-tosylamide-2-phenylethyl chloromethyl ketone (TPCK). Identification of reared specimens was hampered by the uncertain taxonomic status of both genera and species.
