The European grapevine moth (Lobesia botrana; Denis and Schiffermüller, 1775) is considered a key pest for (Vitis vinifera L.) in the Douro Region, Portugal. phenology of both has changed last decades due to increase temperature. Here, we assess potential impact climate change on (a)synchrony species. results show that phenological stages (budburst, flowering veraison) undergo an advancement th...

A new procedure based on partition of the unity has been developed to construct spatial approximation-prediction functions for discrete density functions. This Partition of the Unity Procedure (PUP) provides a family of approximation-prediction functions which depends on several parameters. In order to find the best function we have considered error estimators induced by the Vietoris simplicial...

Greencover crops are widely recommended to provide predators and parasitoids with floral resources for improved pest control. We studied parasitism and predation of European grapevine moth (Lobesia botrana) eggs and pupae as well as predatory mite abundances in an experimental vineyard with either one or two sowings of greencover crops compared to spontaneous vegetation. The co-occurrence betwe...

Lobesia botrana (L. botrana), es una plaga cuarentenaria que provoca danos a la vid, y genera perdidas económicas para región de Cuyo en Argentina. Diferentes investigaciones han buscado salvaguardar integridad los viñedos, generando sistemas alerta basados modelos permitan detectar picos ocurrencia plaga, conocer el proceso crecimiento lapolilla, acuerdo las condiciones ambientales cada región...

In herbivorous insects with more than 1 host plant, attraction to host odor could conceptually be mediated by common compounds, by specific compounds released by each plant or by combinations of common and specific compounds. We have compared the attraction of female grapevine moth, Lobesia botrana, with specific and common (shared) odors from 2 different plants: a wild host (Daphne gnidium) an...

A Tortricidae (Lobesia botrana) has a mutualistic relationship with the fungus (Botrytis cinerea). In this study, we investigated the growth, survival, fecundity and amount of sterols and steroids in larvae of this vineyard pest reared on artificial diets containing mycelium (3%) or purified sterols (0.01%) of the phytopathogenic fungus. Two principal questions related to the physiological and ...
