were surveyed in 2 sites where maize is cultivated in the State of Jalisco in central Mexico.
Members of the genus Promuscidea are regarded as hyperparasitoids of other hymenopteran primary parasitoids
and the coccids are thus their secondary hosts (Hayat, 1998).
19] who observed the effects of guava ripening on large quantity and parasitism ratio of oriental fruit fly, Bactrocera dorsalis (Hendel) 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).
After a developing time of 19-21 days, parasitoids
emerged from the next generation were collected daily from each Petri dish.
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.
Studies of black scale parasitoids
are abundant in the literature, but these studies have not been performed in 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.
DURATION OF PLANT DAMAGE BY THE TOBACCO BUDWORM (HELIOTHIS VIRESCENS) AFFECTS THE ATTRACTION OF A SPECIALIST AND A GENERALIST PARASITOID
TO COTTON ODORS.
