1. Present status of forest and forest products pest problems
i) Insect pest and disease problems have often become serious problems in some plantations since the introduction of tree-farming in the Philippines. Felled logs and green lumber are frequently infested by wood-boring beetles and fungi, and well-seasoned woods are also attacked by powder-post beetles and termites.
ii) Fast-growing tree species have been known to be particularly susceptible to diseases and insect attack. There is an urgent need for basic and applied research in order to implement measures aimed at controlling the insects.
iii) In spite of the alarming situation regarding forest pest problems in plantations, both staff and facilities are insufficient at present for conducting research on these recent problems.
iv) Forest and forest products, insect and diseases observed in the Philippines are briefly reported.
v) Compilation of a list of trees harbouring harmful insects observed in the Philippines up to now is presented.
vi) Bibliography related to forest and forest products insect pests and disease is presented.
2. Observations and surveys on some forest insects
1) As for the main causal agent(s) responsible for the death of the Benguet pine in the Philippines, it is suggested that Ips and nematodes might act as secondary pests while the primary causal agent (s) still remain to be identified.
ii) Observations on some insects of fast-growing tree species are briefly reported.
