Flight dymanic of some lepidoptera species from field crops in Transylvania Plateau conditions

Some results obtained regarding flight dynamicof some Lepidoptera species from field crops, in conditions from Turda zone are presented. During 1990-1997 May - September, there were captured with the pheromonal traps, over 15000 species of some Lepidoptera: Autographa gamma, Amathesc-nigrum, Agrotis...

Summary:Some results obtained regarding flight dynamicof some Lepidoptera species from field crops, in conditions from Turda zone are presented. During 1990-1997 May - September, there were captured with the pheromonal traps, over 15000 species of some Lepidoptera: Autographa gamma, Amathesc-nigrum, Agrotis segetum, A. exclamationis, Mamestra trifolii, Mamestraoleracea, Mamestra suasa, Ostrinia nubilalis, Plutella xylostella and Cnephasiapasluana. Among them there were evidenced the species: Plutella xylostella inproportion of 33percent, Autographa gamma in proportion of 12 per cent, the species of genus Agrotis 11-13 per cent, the species of genus Mamestra 3-9 per cent, Amathes c-nigrum and Ostrinia nubilalis 5-6 per cent and Cnephasia pasiuana 1 per cent. Using the obtained data, the representative flight curves for each species were established, which through their shape through the number and the capture period, showed the number of generations from each species in the conditions from Turda. These flights curves, the plenty and the proportion of Lepidoptera species from field crops, help in establish the best moment for applying the biological and chemical treatments.
