Abstract
Papaya is a tropical tree fruit crop that cannot tolerate freezing temperatures. It has commercial importance because of its high nutritive and medicinal value. Papaya cultivation had its origin in South Mexico and Costa Rica. Papaya fruit are borne on peduncles attached to the main trunk of the papaya tree and are clustered, starting a few feet above the ground and extending up to a foot below the top of the plant adequate water is essential to the uninterrupted growth and production of papaya fruit. Wax layer and waxy fibres over the ovisac and body of mealybug nymphs and adult females protect them from adverse environmental conditions and routine chemical pesticides. Development of male characteristics starts in the middle of the second instar. Male covers become reddish brown and more elliptical in shape, and then transform in stages into the pre-pupal, pupal and adult stages.
