Biology and predation capacity of Parasitus bituberosus (Acari: Mesostigmata: Parasitidae) on Frankliniella occidentalis (Thysanoptera: Thripidae), and free-living nematodes as its complementary prey.

Background: Parasitus bituberosus is common in rose fields and nearby vegetation around Bogotá. In rearing units, it is often aggregated, feeding on Frankliniella occidentalis edaphic phases. Preliminary observations suggested predator immatures can not reach adulthood if isolated.
