We compared biological parameters of the mite predator Hyaliodes vitripennis (Hemiptera: Miridae) reared on live Tetranychus urticae Koch versus two artificial diets used in rearing generalist predators: Coleomegilla maculata lengi Timberlake (Coleoptera: Coccinellidae) and Chrysoperla rufilabris Burmeister (Neuroptera: Chrysopidae). Both coccinellid and chrysopid diet resulted in lower mortality and increased longevity of H. vitripennis, but daily fecundity was greater with the former. The phagostimulant β-sistosterol had the greatest impact on H. vitripennis mortality (lowest) and nymphal weight gain (highest) when added to the coccinellid diet. These results demonstrate that H. vitripennis could be reared on an artificial diet, and suggests that β-sistosterol has phagostimulant properties for this predator.
