| Abstract |
Field experiment was carried out at Sadat city, Menoufiya Governorate, Egypt, during 2005 autumn season to study the population density of spider mite, Tetranychus cucurbitacearum (Sayed) and associated predatory mites on five cucumber varieties (Madena Perins, Hoyland hybrid, Marmar-RS and Beita alpha hybrid) under field conditions. The results revealed that, the Beita-alpha hybrid significantly received the highest number of T. cucurbittacearum, while Perins variety harbored the least one. The rest varieties (Madena, Hoyland hybrid and Marmar-RS) harbored a moderate number. The predatory mites and true spiders indicated the same trend for all varieties. On the other hand, highly positive significant correlation was found between the true spiders and both eggs and moving stages of T. cucurbitacearum on Hoyland hybrid, Marmar-RS and Beita-alpha hybrid. The combined effect of predatory mites and true spiders on the eggs of T. cucurbitacearum was 92.19%; 80.57%; 78.66%; 75.51% and 66.33% for Beita-alpha hybrid, Madena, Marmar-RS, Hoyland hybrid and Perins, respectively, while it was 94.49%; 83.25%; 78.94%; 77.91% and 62.81% on the moving stages, respectively.
