Abstract
Oregmopyga peruviana, pest of the vine, causes damage that reduce the yield and strong infestations provoke the death of the plant. It is present along the Peruvian coast, being a very important pest. The objective of the study is to determine the individual efficacy of nine treatments (buprofezin 25 g·hL-1, chlorpyrifos 96 g·hL-1, pure vinasse, spirotetramat 474.3 g·hL-1, imidacloprid SC 1435 g·hL-1, imidacloprid WG 17.5 g·hL-1, M. anisopliae and B. bassiana 333.3 × 1012 CFU·hL-1, thiamethoxam 900 g·hL-1 and dinotefuran 680 g·hL-1) in different phenological periods. Each treatment was compared with its control using the Student's t-test for independent variables (p = 0.05). In addition, the control percentage was determined using the Henderson and Tilton formula, obtaining for buprofezin 87.4%, chlorpyrifos 84.2%, vinasse 70.1%, spirotetramat 97.2%, imidacloprid WG 95.5%, imidacloprid SC 87.6%, dinotefuran 99.6% and thiamethoxam 91.6%. M. anisopliae and B. bassiana got no control. The results show that eight of the nine treatments had a controlling percentage higher than 70% having significantly lower populations. Furthermore, vinasse is an organic and low cost alternative for the control of O. peruviana.
