ARTHROPODS ASSOCIATED WITH BROMELIA-HEMISPHAERICA (BROMELIALES, BROMELIACEAE) IN MORELOS, MEXICO

A survey was conducted of the arthropod fauna associated with Bromelia hemisphaerica Lamarck (Bromeliaceae) at Yautepec, Morelos, Mexico. In this survey, conducted from January to September 1989, 40.3 percent o f the species represented in the collections were predatory, belonging to the orders Araneae, Acarina (Parasitiformes and Acariformes), Hemi ptera, Coleoptera and Hymenoptera. Herbivorous species accounted for 1 6.4 percent of the total species collected. Among these were Ferrisia virgata (Cockerell) and Dysmicoccus brevipes (Cockerell), which might become pests when these plants are cultivated in monoculture.
