A field-experiment was conducted to investigate population densities of Liriomyza trifolii (Burgess, 1880) on two vegetable soybean (Glycine max [L.] Merr.) cultivars in different irrigation levels in the semi-arid conditions. This research was carried out at the Agricultural Experimental Field of the Harran University (Sanliurfa, Turkey) during the growth periods of 2006, and 2007. The irrigation treatments were 33%, 67 %, 100 %, and 133 % ratios of total irrigation water applied (IW)/cumulative pan evaporation (CPE) with four day irrigation interval. The experiment area was checked once a week during the whole production period. Ten leaves were removed randomly from each plot and living larvae counted. Adult counts were made on yellow sticky trap which placed randomly in each plot. Bean yield was also recorded. Differences of adult number and living larvae were significant between varieties, but showed no significant changes in response to irrigation levels within variety. The number of living larvae and adult of L. trifolii were higher on cultivar Toyohomare than Toyokomachi. However, the population was over the economical damage threshold on all irrigation levels. The highest green pod yield was obtained from Toyokomachi, with I133 irrigation level. Based on the findings, varietal characteristics should be considered and select less sensitive cultivars to L. trifolii and water stress especially in semi-arid and arid areas for successfully growing soybean <br /> </p>}, number={3}, publisher={Harran University}
