ABSTRACT

Biological control of papaya mealybug by releasing parasitoid A. papayae at 100 numbers per hectare proved superior to unreleased field in causing reduction in mealybug population besides recording higher level of parasitoid activity. The mean initial mealybug population was 48.4 in parasitoid released field and 46.65 in unreleased field. The population of mealybugs at 15 and 30 Days After Release (DAR) was found to be 28.95 and 16.45 in parasitoid released field respectively. The pre-release mean population of parasitoid was 1.69 in released and 1.45 in unreleased field. At 30 DAR the population of parasitoid count was found to be 5.10 in released and 2.25 in unreleased field.
Keywords: Papaya mealybug, Paracoccus marginatus, Acerophagus papayae
