| Popis: | The effect of commercial formulation neem oil of the 0.3, 0.4 e 0.5% was evaluated, as it was applied on eggs of Helicoverpa zea with 1, 2, and 3 days old. The experiment was carried out in acclimatized chamber 25 ± 1º C, 70 ± 10% relative humidity and photophase of 14 hours, in the Entomology Laboratory of the CCA-UFES, in Alegre, ES. Eggs of H. zea were glued in paper cards and treated by submersion in the solutions and in the water (control) for five seconds. There are not differences in the eggs viability between the treatments (Tukey p = 0.05), thus demonstrating that there are no effects of the concentrations of the product on different ages of eggs. |
