The objectives were: 1. To study the effect of the density of traps for hectare in the regulation of the population of adults of the generation monitored. 2. To determine the additional effect of the adherent one in the traps on the capture of butterflies of Ceramidea viridis. 3. To compare the effectiveness of the traps with dispersors of the attractive one front of those that contains an emulsion to low concentration. To measure the effect of the density of traps by hectare in the regulation of the population larvary, we use plastic containers of white color of two liters of capacity with a hole of 4 centimeters in which we place an adhesive substance the same that had the attractive. We use two types of adherents the Bio-tac that is a chemical component of polibutan and the greg fish of artisanal fabrication elaborated with vegetable resin. The dodecenil acetate and essence of fruits were used as bait. In the three of the four evaluated generations, it was not obtained significant results for treatments, for what is evidenced that the incorporation modality of the attractive one to the traps, doesn't have influence significantly in the capture of adults even when we appreciate numeric differences. These results in the field, experiment the influence of other biological agents, relative to parasitoides of pustules, space distribution of the plague, the same one that was reflected in high variation coefficients. The adhesive substances with which we covered the surface of the traps, didn't influence on the capture of adults, and the distance in which were placed influences when the infestacion is moderated to high, working in a best wcuy spaced to 50 meters. The attracted adults are the most part females, with approximately 80 % of prevalency. The density of traps, referred to the areas of influence of the test went from 1,1 to 2,58 /ha. |
