Abstract

Microlepidoptera pose a significant threat as vineyard pests. Yet, information about inter-row management effects on natural enemies remains limited. We evaluated the impact of an inter-row tillage gradient on plant cover and the predation rate of microlepidopteran larvae and pupae as a model to estimate potential predation rates of Lobesia botrana in vineyards. The percentage of bare soil measured at the surface level in the inter-rows was the only variable that correlated with the tillage intensity gradient. Predation rates of larvae and pupae showed significant differences between tillage intensities, but did not follow the expected pattern based on the tillage gradient. Bare soil measured at the surface level had a strong influence on predation rates when the tillage gradient was simplified into high and low intensity categories. Ants were the only observed predators, with 11 species identified. They were able to respond quickly in locating and preying on the larvae and pupae offered.
