Susceptibility of three strawberry cultivars to the infestation of the most important pests in Qalubia governorate

Abstract EN

Experiments were conducted during the two seasons of 2018-2019 and 2019-2020 in ‚Qalubia Governorate, Egypt, to evaluate the susceptibility of three cultivars of strawberry (Fertona, Felorida and Festival) to the infestation of red spider mite, white fly, aphid and thrips.

Also the relation ofanatomic characters of three strawberry cultivars leaves in relation to the infestation of Tetranychus urticae and Bimicia tabaciwas also studied.

.

The obtained results showed that the highest mean number of T.

urticae (egg &movable stages)was recorded on Fertona var, being 187.2 and 123.36 individuals/10 leaves and 75.7 & 53.89 eggs/10 leaves during the two studied seasons, respectively.

On the other hand, the lowest infestation was recorded on Florida, it was 14.4 and 53.8 individuals /10 leaves, and 35.6, 56.6 eggs during the two tested successive seasons, respectively.

A significant difference were detected between the anatomical characteristics and the mean numbers of pests where the cultivars have higher thickness attract low number of pests.
