Seasonal incidence of papaya Mealybug, Paracoccus marginatus (Williams and Granara de Willink) in Southern Rajasthan

Abstract

Study on Seasonal Incidence of Papaya Mealybug, Paracoccus marginatus Williams and Granara de Willink in Southern Rajasthan was conducted at CTAE Instructional Farm and Department of Entomology, Rajasthan College of Agriculture, MPUAT, Udaipur during Kharif, 2024 i.e. July to December 2024. The observation made during the study reveals that the peak activity of Paracoccus marginatus on papaya was recorded with the maximum population (91.5 mealybugs/5 cm2/leaf/plant) during 40th Meteorological week. Mealybug incidence showed significant positive correlation with maximum temperature (r = 0.392) and sunshine hours (r = 0.436). Whereas, wind velocity showed significant negative correlation (r =-0.530).
