Timber with and without bark are attacked by Platypus latifinis,tunnels penetrate deep i n t the o heartwood.whoseThe galleries of Phloeosinustuberculatus are of a highly branching type being present just beneath the barkand affects only the superficial layers of the sapwood.As the timber is used in veneer and plywood industries, extensivedamage by P. latifinis may result in the production of poor qualityveneers.Only one insect viz., Pterolophia occidentalis (Cerambycidae) which boresin deadwood has so far been reported on this timber (Mathur &Singh,1 960-c).Large borersSmall borers3 1.

( ,n )Round logs with bark are often attacked bv the large borer,Olenecamptus bilobus. The tunnels run through the sapwood initially andthen penetrate into the heartwood and cause considerable damage to themain bole.The bostrychids, Sinoxylon anale and S.conigerum attack the sapwood.Their galleries are confined to the outer sapwood which is usually discardedwhen the timber is processed.The major use of this timber in Kerala is for making furniture, turneryarticles, agricultural implements, tool handles and heavy packing cases.Literature records (Mathur & Singh, 1960-c) of the borers of thistimber include the cerambycid, Olenecarnptus signaticollis which is closelyrelated to the one collected in the present survey.The beetle, Laemotmetus insignis (Passandridae) was collected fromlogs infested by S. anale and S. conigerum.predatory on bostrychids (Beeson, 1941 ).This species is known to be

Damageby Sphaerotrypes sp. is confined mostly to the superficial layer beneath thebark where several larval galleries radiate from a cylindrical mother gallery.Platypus uncinatus {Platypodidae) was found to cause serious damage tothis timber under prolonged storage. Their galleries often reach as far as theheartwood.Among the borers previously recorded on this timber (Mathur & Singh,1960-c), the cerambycid, Olenecamptus signaticoilis attacking logs with barkand the small borer, Minthea rugicollis (Lyctidae), attacking sawn timber arathe most important. S. anale and Sphaerotrypes sp. are first records on thistimber in Kerala. This timber is used in construction works and for makingheavy packing cases.33.
