Impact of flowers an the demography of western flower thrips Frankliniella occidentalis (Thysan., Thripidae)
Journal of Applied Entomology - Zeitschrift für angewandte Entomologie 123 (9), 569-574
Abstract: The impact of flowers on the population growth of Frankliniella occidentalis was characterized on waxflower plants, Impatiens walleriana. In the presence of flowers, the populations grew exponentially while in their absence, the thrips populations only maintained themselves and showed no growth The difference in number and in size of thrips reared in both conditions suggested that the flowers were essential for the success of thrips development. In the presence of flowers, the distribution of females between the leaves and the flowers varied strongly according to the availability of flowers. By contrast, the proportion of first larvae in the flowers increased up to the last day of the experiment.
