This product utilizes two different species of predator. Both attack greenhouse whitefly (Trialeurodes vaporariorum) and tobacco whitefly (Bemisia tabaci). Encarsia goes for the third and fourth larval stage, whereas Eretmocerus prefers the second and third larval stage.
Eretmocerus has the added advantages of working at higher temperatures, greater host feeding ability and more resistance to chemical pesticides.
Encarsia prefers the greenhouse whitefly, while Eretmocerus will attack both species of whitefly.
