Abstract

Environmental changes at the experimental area of the Department of Entomology, University of São Paulo, in Piracicaba, in a period of 25 years, were evaluated using a faunistc insect analysis of samples collected by light traps in 1965/66 and 1990/91. A reduction of 35.1% in the faunistic index between these two periods was recorded. Consequently, the diversity index also decreased by 60.3% due to the low number of insects collected. These indices suggest a considerable environmental change in the experimental area over this 25 years period.
