Abstract: During 18 months (May 2003 to August 2004) collections were made of the larvae and adults of Melolonthidae (Scarabaeidae-Pleurosticti) in onion crops (Allium fistulosum L.) and pasture (Pennisetum clandestinum Hochst) located in the municipality of La Florida and the area surrounding the capital of Pereira, Risaralda (Central Coffee Region, Colombia). A total of 1,949 larval specimens were captured that represented 11 species from which the genera Phyllophaga, Plectris, and Cyclocephala were identified, belonging to three tribes and three subfamilies of Melolonthidae. The adult collection totaled 5,267 specimens belonging to the genera Cyclocephala, Aspidolea, Golofa, Heterogomphus, Plectris, Phyllophaga, Astaena, Chariodema and Isonychus.
