Field experiments were conducted at Gezira state during two winter seasons (2015/16-2016/17). Two in first season (2015/16) experimental farm University Research Station Farm ...

population density and spatial distribution of thrips tabaci lindeman on seven soybean varieties (williams, tellar, sahar, dpx, l17, sari and zane) and one genotype (ks3494) were studied in tehran region, during 2007. the highest population density of the thrips per leaf was recorded on dpx and on ks3494 (0.810.05 and 0.800.05, respectively). the lowest population density was observed on l17 ...

food choice in omnivorous animals is influenced by the balance of nutritional needs, food availability, and quality of a particular food items. here, we study whether omnivorous onion thrips, thrips tabaci lindeman, feed on the eggs of its competitor tetranychus urticae koch (acari: tetranychidae) when an alternative supplemental source is, or is not, available. thrips were either fed a cucumbe...
