【 摘 要 】

Pineapple mealybug wilt has been reported as one of the most important diseases affecting pineapple crops worldwide. Thisstudyaimedtodeterminetheprevalenceofmealybugsassociated with two agroclimatic zones of pineapple production inthedepartmentofValledelCauca,Colombia.Thesurveywas conducted in the upper (Dagua, Restrepo, La Cumbre and Vijes) and lower (Buga and Palmira) land zones. A total of 75 MD2 pineapple plots in different development growth stages wereevaluated.Themealybugswererecordedmainlyintheupperlandzone,withaprevalenceof32%.Concerningtheplotsgrowthstages,thehighestprevalencewasobservedinsecond-cycleplots(13.3%),followedbythird-cycleones,including abandoned plots (9.3 %), and first-cycle plots (6.7 %), which were associated with the use of pesticides. Dysmicoccus brevipes was the only mealybug species (Pseudococcidae) found on pineapples in the study area.
