according to Beeson (1941) a female may lay up to 50 000 eggs. The female moth<br />

has an average lifespan of seven days. Eggs hatch in about 10 days and the newly<br />

hatched larvae disperse on silk threads, aided by wind. They can withstand<br />

starvation for up to six days (Beeson, 1941). They move into bark crevices, protect<br />

themselves under silk web and bore into the tree.
