Popis: | In the period 1998-2003, in the vineyard Stefanesti-Arges, observing was carried out, with the help of pheromone traps, of the population of grape moths, Eupoecilia ambiguella Hb. and Lobesia botrana Den et Schiff. The different climatic preferences of both species, establish that, in accordance with the yearly conditions, one of the two species is dominated by the other. The year 1998 is the only year when the percentages of captures of the two species are nearly: 57% - L. botrana and 42,89% - E. ambiguella, while in 1999 is the only year when E. ambiguella dominated in number the species L. botrana - 66,28%. For meeting this situation it needed two years of consecutives optimum climate for the activity of species E. ambiguella (like the year 1998 and 1999). In the period 2000-2003, the species Lobesia botrana was dominated by E. ambiguella, but as a result of very raised temperatures of summers of years 2000, 2002 and 2003, the population of L. botrana diminished very much and there was no need for fighting back treatments. |
