Muhammad Faheem Malik, Mohammad Nawaz and Zahid Hafeez    

Abstract: A comparative study of six onion (Allium cepa L.) varieties (Red Creole, Chiltan-89, Local, Sariab Surkh, White Globe and Local Kandhari) was conducted against thrips infestation in Quetta, Pakistan. The results of the trial revealed that Thrips tabaci Lindeman (Thysanoptera: Thripidae) is the attacking species to onion in the region. All the varieties were infested by thrips at various degrees. Maximum yield (11500 kg ha-1) was obtained by Chiltan-89 and minimum (812.5 kg ha-1) by Red Creole. Local Kandhari followed by Sariab Surkh were the most susceptible to thrips infestation while Chiltan-89 was optimum. The population got its peek (14.74 thrips per plant) at 27.910C with 52.64% humidity in the month of August. On the basis of the results onion variety Chiltan-89 is recommended for commercial cultivation in the region.
