摘要

The parasitoid Habrobracon hebetor is a polyphagous parasitoid of several lepidoptera larvae, including Spodoptera species. H. hebetor is already used to control several economically important insect pests. It has also been reported on the fall armyworm (FAW), but its utilization against the FAW requires further investigation. First, we assessed the acceptability of different larval instars of S. frugiperda for parasitism by H. hebetor. Second, we assessed the parasitism of H. hebetor on S. frugiperda in comparison to Corcyra cephalonica, the factitious host on which the parasitoid is mass cultured. Finally, we tested the parasitic ability of H. hebetor progeny developing from S. frugiperda larvae. The H. hebetor female paralyzed and killed all 3rd -6th instar larvae of S. frugiperda but parasitized and laid eggs only on the 5th and 6th instar larvae. With respect to parasitism and laying eggs, H. hebetor has a marked preference for C. cephalonica larvae. Likewise, H. hebetor developing on S. frugiperda larvae had lower performance than parasitoids that have been reared on the factitious host, C. cephalonica. However, because H. hebetor is relatively easy to mass rear, it could still be considered a potential supplementary biological control agent with other parasitoids against the FAW.
