Abstract: Survey was carried out to study the distribution, infestation and damaging level of insect pests of Pineapple (Ananas comosus) during 2017 cropping season in southern Ethiopia. Insect pests were observed and identified at their sites in the surveyed areas. In addition, samples of insect pests and infected plant parts were collected and insect images were taken. The samples were diagnosed in Ambo Plant Protection Research Center laboratory. A total of five species of insect pests were recorded as Pineapple (Ananas comosus) insect pest with different rate of infestation and damage level. Pineapple Mealy Bug (Dysmicoccus brevipes) was recorded with relatively high infestation and damage level from Kefa zone (Ginbo district), while others were considered as minor pest due to low infestation and damage level. Therefore, it is important to design control options for the Pineapple Mealy Bug to ensure plant health and pest action under economic threshold level.
