| Mass rearing of parasitoids is a fundamental step for biological control programs. The biological characteristics of Palmistichus elaeisis Delvare & LaSalle (Hymenoptera: Eulophidae) were evaluated in pupae of Anticarsia gemmatalis Hubner (Lepidoptera: Noctuidae) stored at low temperatures. Twenty four hours-old pupae of A. gemmatalis were stored at 12 °C for 0, 1, 3, 6, 9, and 12 d and then exposed to parasitism by P. elaeisis females. The life span of P. elaeisis was affected and ranged from 19 to 24 d on the pupae of the host. Parasitism reached 100% of the host pupae after storage in all periods at 12 °C, and adults emerged from 20.00 to 54.54% of them. The progeny of P. elaeisis ranged from 71 to 198 and had an inverse relationship with the... |

| 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. |
