Prospects of controlling the aspargus fly in integrated and ecological crop cultivation
Project
Project code: 2815NA177
Contract period: 06.03.2017
- 31.03.2020
Budget: 69,516 Euro
Purpose of research: Applied research
The asparagus fly (Plioreocepta poeciloptera) is an important insect pest in asparagus crop production. In this project new approaches and strategies for the sustainable control of the asparagus fly in integrated and ecological crop production shall be developed. The project focuses on amending missing knowledge of the biology and ecology of the asparagus fly, evaluating alternative control measures and revising the preliminary economic thresholds and economic injury. Based on the results a sustainable control concept should be developed and transfered to advisers and integrated and ecological producing asparagus growers. - Eclosion trials with aspargus fly pupae will be conducted to work out missing biological data. These trials will focus on the influence of pupal age and the photoperiod on eclosion time, as well as on potential factors (e.g. soil), that might influence the general occurence of the fly. These results will be the base for recommendations for optimised planting and harvesting times. - By using green sticky traps and controlling infestation incidence in asparagus plants, data of the flight and dispersion behaviour will be gained, which will result in recommendations for the optimal distances between single asparagus fields. - Mechanical treatments in autumn, mass trapping and sowing of interseeds will be evaluated for their efficiency to reduce pest infestation by conducting small or large plot trials. - Based on the above findings the economic thresholds and economic injury levels shall be revised. - The results will be summarised and one sustainable control strategy will be developed, comprising useful alternative elements. The findings will be published in articles, flyers and presentations.
