Notes: Pineapple cuttings of the cultivar Smooth Cayenne, planted in plastic pots were infected under field conditions with 0, 1, 5, 15 and 30 pineapple mealybug Dysmicoccus brevipes (Cockerell, 1893) per plant, with the objective to determine the injuries and damages this insect in terms of its density. The work was developed using a completely randomized design with four replications and five treatments. The results showed that mealybug reduced plant height as well as shoot and root weight. A population density of only 0.6 mealybug/plant was sufficient to transmit pineapple wilt.
