Conteúdo: 	This paper reports on the morphology, biology and pesticide tolerance of Cheletogenes ornatus, the most common predator of Pinnaspis aspidistrae in the region of Juazeiro- Bahia- Brazil. Some differences between C. ornatus from Brazil and redescriptions in the literature are mentioned in this paper. At 28 +ou- 5oC the duration of the life cycle was 40.6 and 31 days for female gametes and male gametes respectively. Females had 2 nymphal stages while the only male obtained in the laboratory had a single nymphal stage. C. ornatus reproduced by thelytokous parthenogenesis, and male gametes were seldom produced. The peak was ca. 0.8 crawler of P. aspidistrae/gemale gamete/day. The least harmful chemicals to adult females of C. ornatus were methyl parathion, malathion, cyhexatin, zineb and sulfur. Those chemicals caused less than 10% mortality of female gametes at he recommended rates on citrus. COncurrently, the first 2 chemicals caused over 70% mortality of crawlers of P. aspidistrae in the laboratory at the recommended rates.
