- Abstract
In Romania, a particularly important role in the new organization of agriculture is farmers' associations, which aim to ensure the concentration and specialization of production. After all the studies - Over the years, losses due to pests, diseases and weeds amount to several billion lei, which requires action at multiple levels. Insects show great plasticity in their adaptation to the conditions of existence forming an inexhaustible number of morphological and biological types. From this large number of insects is part Oulema melanopa L. (oat/cereal leaf beetle), frequently reported in cereal crops in Banat. The purpose of this research was to identify, within three years, the most sensitive wheat varieties to the attack of Oulema melanopa L species. Studies were conducted in the experimental field of the discipline Nematology and Acarology, located on the left side of the national road Timisoara-Arad. Observations were made on 16 wheat varieties, of which: 8 awned species and 8 varieties unawned (domestic and imported) from 2009 to 2011. Entomological material was collected with entomological net, by repeated scything/mowing wheat crop. A sample was composed of 50 forages (25 on one side, 25 on the other side, alternating) from top to bottom, going zigzag, large diagonal of the plot. Oulema melanopa L. larvae were collected manually.Varieties that are more resistant to the attack of Oulema melanopa L. were Calango and Soisson, of the awned, and of the unawned varieties were noted Carolinum and Feny .In recent years, Oulema melanopa L. is attacking the leaves of maize (late hybrids ) where maize is located next to a plot of attacked wheat. As such, these parcels are a possibility of propagating the species and also the land will be a reserve for next year, if cultivated with wheat (simple rotation maize - wheat).
