Description:Excerpt from Preliminary Bulletin on Insects of the Cacao: Prepared Especially for the Benefit of Farmers If the insects are captured upon emerging they will have no opportunity to lay their eggs, but as this can not be done in all cases, a close daily survey of the trees at the time when the adults of Cicada are beginning to be numerous will reveal the work which they do on the twigs. The characteristic appearance of the twigs after eggs have been deposited in them is shown in fig. 8. It was claimed a number of years ago that the Cicada only deposits her eggs in dead twigs, but observation has since proven that this is not the case, she invariably choosing live wood for this purpose. The short time during which the eggs remain in the slit would not be sufficient for the growth to crush them, and moreover, the growth of a twig which has been lacerated by the ovipositor of the Cicada is away from the wound, causing the latter to gape within a year from its formation, as shown in fig. 9. If these twigs are carefully removed by means of a very sharp knife, and if they are afterwards destroyed by burning, while the eggs are yet unhatched, much can be done to lessen the number of Cicada attacking the trees.We have made it easy for you to find a PDF Ebooks without any digging.
