Resumo: | Erinnyis ello is one of the main pests of the cassava crop, and its natural enemies including egg, caterpillar, and pupal parasitoids. The aim of this study was to evaluate parasitism and biological aspects of Tetrastichus howardi on E. ello pupae. In general, parasitism and emergence of T. howardi on E. ello pupae was 64%. Cycle duration (egg to adult) of T. howardi on E. ello pupae was of 20.12±0.15 days at 25±2°C, 70±10% relative humidity, and 14-h photophase. The progeny of T. howardi by E. ello pupae was of 466±0.44. Longevity of T. howardi females and males was of 15±0.57 and 12±0.93 days, respectively. The sex ratio was of 0.95±0.06, and the ratio of females per female was 44±0.45. T. howardi parasite and develops on E. ello pupae.
