温室非洲菊上西花蓟马种群动态和空间分布
Population Dynamics and Spatial Distribution of Western Flower Thrip on Flowers of Gerbera jamesonii in Greenhouse
摘要
Abstract
In the study, aggregate indexes, I wo and Taylor regression formulations were used for spatial pattern and population dynamics of west flower thrip ( Frankliniella occidentalis ) on flowers of ger-bera in greenhouse by the investigation of population of thrips on different florescence of gerbera in a flower base of Kunming. The results showed that the dominant species was WFT (F. Occidentalis ) which accounted for 96% of total thrips in the blooming stage, and the number of adult increased along with the quantity of blossom uplifted that up to 15 per flower in the blooming stage, but the most population of larva was 36 per faded flower. It also that the amounts of WFT changed obviously with the temperature increasing or decreasing, and the harm peak of thrips was in mid-May. The spatial distri-bution pattern of the WFT adults and larvae belonged to aggregating distribution and the aggregation degree enhanced with the rise of population density, the primary cause of adult aggregation was environmental factor and their own behavior, but for larvae, the main reason was the environmental factor. Theoretical sampling within allowable error was calculated by a and β parameters of Iwao regression formulation, which provided an effective method for sampling and investigation, and also provided a theoretical basis for forecasting and prevention of WFT.关键词
