How did Codling Moth Spread all over the world?
Due to unrestricted movements of fresh fruits from one country to another in the past, this insect gradually spread to uninfested areas, ultimately becoming cosmopolitan. It seems that the most common mode of its spread from one place to another has been through the transport of infested fruit and the packing material. Codling moth has remarkable ability to adjust to climatic and trophic conditions. Besides apples, the codling moth can develop on other pome fruits such as pear and quince, on stone fruits such as apricot, plum and peaches as well as on walnuts (Newcomer and Whitcomb 1925), apricot, almond, pecan nuts and pomegranates (Nel 1985).
