Beneficial insects; Insect pests. - 473 - INSECTS NOT KNOWN TO OCCUR IN THE UNITED STATES A DRY-WOOD TERMITE (Cryptotermes dudleyi Banks) Economic Importance: Termites of this genus are very destructive pests of hard, sound, dry wood in man-made structures such as buildings and furniture. Dry-wood termites are so-called because they feed on and live in dry wood. The name "domestic" is applied to several species of Cryptotermes since they are confined to man-made structures and do not compete with other dry-wood termites under "wild" conditions. In addition to C. dudleyi; C. domesticus(Haviland), C. havilandi (Sjostedt) and C. brevis (Walker) are important species in various areas of the world. The latter species, C. brevis, has been recorded in the southern United States. The presence of dry-wood termites in structures is indicated by small heaps of frass or fecal pellets beside or below infested hardwood. An infested piece of timber removed for inspection will show galleries filled with frass. The frass is uniform in size, regular in shape, oval with concave surfaces and seed-like. Although the population of an individual dry-wood termite colony is small and can exist in a few cubic inches of timber, a high degree of damage is obtained by large numbers of colonies living close together. Distribution: Recorded in Panama, Costa Rica, Colombia, India, Ceylon, Philippines, Indonesia (Sumatra, Java), New Guinea, Australia (Northern Territory, Queensland) and the East African Coast of Kenya, Tanganyika and General Distribution of Cryptotermes dudleyi Hosts: Attacks dry hardwood of all types though some hardwoods such as west Indian mahogany, teak, mvule and belian are resistant for long periods before becoming susceptible to damage because of weathering or other factors. Life History and Habits: Colonies of dry-wood termites are small, only a few hundred individuals in each colony, compared with thousan
