Marietta
Marietta is a genus of chalcidoid wasps in the family Aphelinidae. Species in this genus are obligate hyperparasitoids, attacking primary parasitoids of Hemipteran pests rather than the pest insects themselves. The genus was established by Motschulsky in 1863. Marietta species have been documented in association with parasitoids of psyllids, mealybugs, and other economically important insect pests, making them relevant to biological control programs.
