Abstract
Biological studies were carried out on the potato tuber moth Phthorimaea operculella (Zeller), when it fed on three different potato varieties: Kara,Spunta and Diamond to determine the ability of Ph. operculella to feed on , develop, fecundity and life table parameters as a sole food sources under laboratory conditions of 25 ± 2°С and 65% R.H. obtained results and statistical analysis showed that developmental stages, fecundity and life table parameters of insect were affected by the tested different food types , where as, total immature stages lasted (28.38 ±1.17) , (28.37 ± 0.65) and (24.50 ±0.87) days for female , when insect fed on the above mentioned diets respectively . Female oviposition period lasted (29 ,31 and 31 days ) which deposited eggs reached maximum to ( 65.87, 55.18 and 68.44) eggs with daily average number of (3.058, 3.518 , 3.753) eggs/female when insect fed on the three potato varieties Kara, Spunta and Diamond respectively .
