Some morphological and biological characteristics of Pistachio Twig Borer Moth Kermania pistaciella Amsel (Lepidoptera: Tineidae)
Abstract : In this study, it was determined that K. pistaciella females carry an average of 65 eggs and lay their eggs one by one 61.66% on the leaf stem. It was recorded that the egg color becomes completely transparent when the first instar larvae enter the tissue directly from where the egg is found, and a small dark ring-shaped spot is seen where the egg is attached, and that eggs hatch in an average of 8 days under natural conditions. It was observed that the larva is yellow and average length of 0.5 mm when it first hatches from the egg, and after going through four larval stages, it completes its larval period, which lasts for an average of 10.5 months, and starts to weave a cocoon by coming out of a hole the size of a pinhead it has opened on the shoot, and that it remains in the cocoon for a few days during the larval and prepupa stages and becomes a mummy-type pupa. It was determined that 85% of the pupae of the moth were found in female pistachio trees and the average pupa period was 47 days. It was determined that average sex ratio was (male:female) (2:1).
