<span name="style_bold">Presence of four-eyed fox (<span name="style_italic">Philander opossum</span>) in pineapple crops (<span name="style_italic">Ananas comusus</span>). </span>The objective of this work was to determine the presence of four-eyed Fox (<span name="style_italic">Philander opossum</span>) in pineapple crops (<span name="style_italic">Ananas comusus</span>). <span name="style_italic">Philander opossum</span>) in areas of organic production of pineapple (<span name="style_italic">Ananas comusus</span>), in Santa Cecilia de La Cruz, Guanacaste, Costa Rica. Catches were made with snap traps, as part of a study of rodents in biweekly samples from February 2008 to February 2009. Were captured eight juveniles, from March to August, indicating that the species is in reproductive activity from the end of the dry season and through the rainy season. At least one of the individuals ate pineapple, as shown by stomach content analysis. However, the level of damage observed in the field is not enough to consider this species as a pest of pineapple, but rather as an opportunistic species that takes advantage of ripe fruits left in the field after harvest. The collection of individuals for several months indicate that this species uses organic pineapple plantations as part of its habitat, which contradicts the widespread idea that monocultures do not provide minimum conditions for wildlife species as visiting or inhabit it.), in Santa Cecilia de La Cruz, Guanacaste, Costa Rica.
