Eucalyptus Spp.M yrtaceaeCelosterna scabrator (Fb.) (Cerambycidae)Eucommatocera vittata White ( I , )Small borersSinoxylon anale Les.(Bostrychidae)Celosterna scabrator bores in live E. tereticornis and the grubs continueto develop in cut timber. Sinoxylon anale has been found to attack thesapwood of E. grandis and the bark of E. torelliana.The outer sapwood of
25E. grandis was tunnelled by Si/esis indicus (Buprestidae). The cerambycid,Eucommatocera vittota was collected from the bark of E. grandis, but whetherit cause any damage could not be asceitained.Large borersSerixia sp.23. Garcinia indica Chois.Clusiaceae(Cerambycidae)Small borersNilSerious damage was caused by this species to stored logs ofGarcinia indica. The affected logs were riddled by large holes distri-buted about a centimeter apart and the galleries extend as far as theheartwood. The holes were 0.5 cm in diameter. Timber thus affected isnot usable for making packing cases and cabinets for which this timber iscommonly used.Mathur and Singh (1960-b) have recorded Stromatium barbatum, anothercerambycid, from this timber.Large borers24. Gmelina arborea Roxb.Verbena cea eAcalolepta rusticatrix (Fb.) (Cerambycidae)Dihamus cervinus Hope ( 1, )Small borersXyleborus fornicatus E ichh. (Scolytidae)The cerambycids, Acalolepta rusticatrix (Fig. 1 ) and Dihamus cervinusattack sick or unhealthy trees and may persist in freshly cut timber. Thegalleries are extensive and seen longitudinally through the sapwood.The scolytid, Xyleborus fornicatus attack branches of living trees andoccasionally stored poles (Fig. 12) as well.
