Members of the genus Promuscidea are regarded as hyperparasitoids of other hymenopteran primary parasitoids and the coccids are thus their secondary hosts (Hayat, 1998).

Parasitoids are one of the most important biological control agents for pests in agricultural systems, due both to their natural occurrence and to their use in biological control programs (Bale et al.
In the laboratory studies conducted at 28 [+ or -] 2[degrees]C, it was observed that these parasitoids completed their life cycle between 23-27 days, and the surviving adult lived for 4-9 days (MANI & KRISHNAMOORTHY, 1989).
This gradually shifts toward increasing control by the specialist parasitoids we introduced, such as T.
longicaudata under field conditions in southern Brazil, helped to motivate the present study aimed at evaluating the effect of releases of this parasitoid into populations of fruit flies and native parasitoids in loquat, peach, strawberry guava and persimmon trees in the city of Eldorado do Sul, RS, Brazil.
The results suggest that starved parasitoids are more effective biological control agents: they locate and kill their hosts more quickly than do un-starved parasitoids, and kill more hosts using the saved time.
Navasero said the parasitoids must have naturally started growing in number since 2013.
