Abstract: 

Some biological aspects of Emposaca decipiens Paoli were investigated on different bean species (Phaseolus vulgaris L., P. lunatus L., P. calcaratus Roxb. and Vigna sinensis L.) under field and laboratory conditions (26 ± 1oC, RH: 70 ± 5% and a photoperiod of 16L: 8D h.). The species of the host plant had no significant effect on incubation period, but the nymphal instars, development time, adult longevity and life span were affected by host plant species significantly. The shortest and longest development time in the field condition were occurred on V. sinensis (22.58 ± 0.50) and P. calcaratus (27.17 ± 0.67), respectively. But in laboratory conditions these parameters were observed on V. sinensis (20.71 ± 0.57) and P. vulgaris (29.29 ± 1.00), respectively. Adult longevity on V. sinensis had the longest duration. In contrast, the shortest adult longevity was observed on P. vulgaris. Surface of the leaves in V. sinensis is smooth and without trichomes, but presence of the hoocked trichomes on three other host plants especially in P. vulgaris assumed as the most important reason of their unsuitability for the leafhopper.
