| Popis: | Dynamic climate regimes have been developed mainly to reduce energy consumption in the greenhouse, and this has been the main reason for their adoption by growers. During recent years, Danish growers have observed that problems with pests have diminished since they changed from the traditional rigid climate regime to a dynamic regime. The trend has also been observed in scientific experiments testing different dynamic climate regimes. The present experiment shows that the influx of thrips from outside into the greenhouse was reduced by 40% under a dynamic climate regime compared to a traditional rigid regime, and that this was related to the opening degree of the vents. Vents were open on average 7% under the dynamic regime and 33% in the traditional climate. The influx of thrips was linearly correlated with density outside the greenhouse (P < 0.0001) and with opening degree of the vents (P = 0.0001). |
