Biological data revealed that the egg stage of Campoletis flavicincta lasted from 2 to 4 days and the larval stage comprised 4 instars. The larval and pupal stages lasted 7.14 +- 0.05 and 8.24 +- 0.44 days, respectively. The longevity among laboratory culture females was shorter than those originated from field collected pupae. The sex ratio was largely affected by host size. The life cycle averaged approximately 23 days. During the oviposition period, the female was able to deposit an average of 146 eggs. This ichneumonid, normally solitary endoparasite, was able to deposit 2 to 4 eggs/larva when host population densities were low, but without any successful development
