Beetles of the species Sitophilus oryzae and S. zeamais are pests of great economic importance since they attack not only rice and maize but also several other cereals. In fact, these beetles are one of the most visible threats to sustainable food production. Current study estimated the genetic variability of S. oryzae in two samples, one from the State of Paraná (PR), Brazil, and another from the state of Rio Grande do Sul (RS), Brazil, and a sample of S. zeamais from the State of Santa Catarina (SC), Brazil. Isozyme electrophoresis in starch gel technique was employed to analyze eight enzyme systems (AAT, ACP, GDH, GPI, IDH, MDH, PGM and ME). Average heterozygosity rates were 0.0091, 0.0100 and 0.0000 and expected heterozygosity rates were 0.0419, 0.0452...
