Abstract

Mango is the most popular fruit in the orient, particularly in India. Among the many insects which are known to occur on the mango plant, the commonly known Nutweevil' or Stone weevil' is the important one. The insect is a specific pest on mango. The grubs and adults feed on the endocarp of the fruit and hasten the maturity of the fruits resulting in the fruitfall from the trees. Recently, the import of Indian mangoes into U. S. A. has been withhold for the reason that the pest might be introduced into U. S. A. where the insect is not prevalent. This fact drew the attention of the Government and the Ento- mologists in India and studies were initiated on the different aspects of the pest. Investigations on the nutweevil's varietal incidence on mango and its chemical control were carried out for two years and the results are presented in this paper.
