| Abstract | ||||
| A field experiment was conducted at the experimental farm attached to EI- Khanater, Horticulture Research station, Qalubia Governorate during two successive seasons of (2000 and 2001) to study the population density of PTM in five potato varieties Field trials were carried out to estimate the number and duration of potato tuber moth phtbotimeee opercu/ella (Zeller) in the field and at storage. It appears that the reliable appearance of Potato tuber moth phthorimaea opercu/ella (Zeller) moths took place during March until June in the field but at storage appears from July to the beginning of September .. The effect of some bioicides and Sumithion against PTM in storage was also studied. Results obtained showed that, Most susceptible variety to the potato tuber moth (PTM) was Picasso followed by Nicola, Agria, and Santana variety while Desira variety was the least susceptible one. The tested compounds arranged, according to the average effect percent reduction of infestation as follows: Sumithion, ( Granulosis virus (GV) + Dieple 2-X ), dieple2-X and GV descendingly | ||||
