Abstract
The first part of the work consists of an annotated list of the insects affecting the trees. The host trees are mentioned by their scientific names in alpahabetical order, and the insects are listed under each species of tree. Directly under the name of each tree, the family to which it belongs is cited, followed by notes on distribution, uses or economic importance and common names of the tree species. Then the insects are listed or recorded, following more or less this sequence: insects affecting the flowers, fruits or seeds, twigs, branches, trunk and roots. Often, species attacking the decayed wood or resting on the tree will be mentioned at the end of each 565 tree discussed. Only the insects affecting the trees are recorded, that is, such records as "on the leaves", or "collected on the fruit", "on the trunk", etc., are not taken in consideration in this work. The parasitic forms are only mentioned when the specific host is known, otherwise parasites and predators just resting on leaves or other parts of the trees are not listed. This Survey is based on the insect population studies on 245 tree species, belonging to 169 genera. In the annotated list some trees only show two or three insects records while others might show thirty, forty or more records.
