Abstract  In 1996 and 1997, several pests and a semi-parasitic plant species were identified as pests of the neem tree in Kenya, East Africa. Some damage was caused by a gall mite (Phyllocoptes sp.) at Mbita Point in western Kenya in a nursery and on older plants. The potentially dangerous scale insectAonidiella orientalis was widespread in western Kenya but not harmful for the time being. In coastal areas the semi-parasiteCassytha filiformis was very common. This plant is able to kill mature trees growing under unfavourable conditions. As in West Africa, fruit bats likeEpomophorus wahlbergi were useful due to their feeding activity on the pulp of ripe neem fruit, making consequently depulping (by man) was unnecessary.
