RESUMO
Aiming the discovering of new products with less impact to the environment, there were made experiments aiming to evaluate the efficiency on control, as well as the feeding inibit result on soya caterpillar (Anticarsia gemmatalis).with different vegetation stratum in different commercial soya tillings in Uruguaiana and Santa Maria (RS), from january to March, 2005 under low, medium and high population pressure. There were evaluate nim oil at 5%, watered stratum of cinamomum at 1/6 (p/v), distilled of Timbó 1/1 (v/v), distilled of araticum 1/1 (v/v) standart treatment (permetrina), dosage of 0,05 L ha-1 and testifying treatment (water). In all the treatments adherent spreading at 0,1% was used. The doses were applied at tilling, of soya plants and there was noticed that the concentrations experienced had some insecticide activity on Anticasia gemmatalis causing high mortality. The mortality changes with the use of the different stratum grub state of the insect, population pressure and weather conditions of the place. There was noticed that the leaf eat away by caterpillars under the effect of stratum tested was little when compared with, those of tistiled treatment, even when made on high population pressure.
