Pineapple Mealybug Wilt-associated Virus (PMWaV) is one of the main diseases that affect pineapples all over the world, including Sipahutar, North Tapanuli, Indonesia. Currently, there are no studies or information on PMWaV disease as well as the species of mealybugs found in sipahutar pineapples. Therefore, this study aims to identify the mealybugs causing PMWaV in sipahutar pineapple. Data were obtained from 3 (three) villages, namely Siabal-abal II, Onan Runggu, and Sabunganni Huta V, to assess the disease incidence and collect mealybugs. The results showed that the disease incidence of PMWaV in the 3 villages were between 15.6 - 21.6%. The highest disease incidence was found in Siabal-abal II (21.6%), followed by Onan Runggu (21.3%), and SabunganniHuta V (15.6%). The mealybugs found on pineapple sipahutar with PMWaV symptoms in the 3 surveyed villages were identified as Dysmicoccus brevipes.

Abstract-

The authors conducted a survey of Pineapple Mealybug Wilt-associated Virus (PMWaV) on pineapple plants in four pineapple-producing sub-districts in North Tapanuli, namely Sipahutar, Pangaribuan, Siborongborong, and Tarutung. This survey aims to detect the presence and distribution of PMWaV in North Tapanuli. The survey found PMWaV in pineapple plants in all survey locations with varying symptoms such as wilting to a yellow-red colour and curling leaf tips, curling and drying leaves and leaf tips, and showing symptoms of wilting to a redand yellow colour. The results showed an incidence rate between 15.6 to 80%. Sampang ni Huta V, Sipahutar, showed the lowest incidence rate (15.6%), while Lobu Siregar, Siborongborong, showed the highest (80.0%). Meanwhile, the severity rate was between 14.0 and 65.0%. Pancur Natolu, Pangaribuan, showed the highest severity rate (65.0%, severe), while Siabal-abal II, Sipahutar, showed the lowest (14.0%, moderate).
