Abstract EN
Guava (Psidium guajava L) is a new host to the whitefly, Aleuroclava psidii (Singh) (Hemiptera: Aleyrodidae) at Qaliobiya Governorate.
The high infestation by A.
psidii causes serious damage and noticeable reduction in quantity and quality of the yield.
The present investigation carried out to study the population dynamics of A.
psidii nymph in relation to the different phonology stages of the defoliated and prune guava trees.
The overall means of the first year was 4285 individuals compared with the overall mean count of the second year which was 2449 individual.
The whitefly, A.
psidii have two periods of activities (low and high activity periods) on guava trees.
Also, predators and parasitoid will be surveyed and identified.
The relationship between the nymph population, three climatic factors (minimum, maximum temperatures and RH %) and plant age were studied
