Enhancement of the egg parasite Trichogramma semblidis (Auriv.) (Hym., Trichogrammatidae) for control of both grape vine moth species in the Ahr valley 1, 2

In the present study host eggs from a stockculture were exposed periodically in the vineyard to increase the population of Trichogramma semblidis and thereby the rate of parasitization in the natural occurring grape vine moth population. During the whole season every week cards with at least 100 moth eggs were attached to 15 grape stocks in an untreated plot. The parasitization of the exposed eggs, emergence of parasites and the parasitization of the natural occurring moth population were recorded. Egg parasitization was highest in May/June and following a decrease in population density again in September. In the plot center significant higher rates of parasitization were found than in the borders. In the natural occurring grape vine moth population a parasitization of 26.7% and 25% were recorded in the 1st and 2nd generation, respectively, resulting in a reduced infestation of grapes with larvae of both generations.
