  Seasonal abundance of the western flower thripsFrankliniella occidentalis in the arava valley of Israel

  摘要：

  Flowers of 22 plant species grown in the Arava region of Israel were sampled at periodic intervals to study the seasonal abundance of Frankliniella occidentalis (Pergande) (Thysanoptera: Thripidae). Samples were collected from the most common cut-flower and vegetable plant species in this area during 1997 and from pepper in 1996-1998. Western flower thrips (WFT) was detected on 19 of the plant species surveyed, and it reproduced on numerous plant species. WFT counts peaked in late February-April and in October-December. The peak density of WFT during March in our survey corresponded to the peak flowering of cut-flower plants (during spring) and sweet pepper (during autumn). Thrips population was less abundant during autumn than in spring and was very low during summer. The possible reasons for fluctuations in thrips densities are abiotic factors (temperature and relative humidity), and availability of flowering plants. The high temperature (>40degreesC) and low humidity (similar to20%) in summer caused a drastic reduction in WFT populations, although some flowering plant species were available in this season. WFT population remained low until October, when adults appeared in large numbers on flowering pepper. We assume that the thrips had survived the hottest months by aestivation and migrated to the plants when air temperature decreased. In most samples from the cut-flower fields, 84.8% were adult WFT; only during the period from the end of January to March, did the proportion of immature stages in the thrips population increase to 31.6%. Females always outnumbered males (71% females). In pepper fields during the first cropping month the thrips population included 96% adults; from November onwards, the proportions of adults and immatures were almost equal; and females outnumbered males. Organic pepper fields were not infested with thrips because of the presence of the predatory bug Orius albidipennis (Fieber).
