This research emphasized biological investigations involving relationships between insects and plants to develop an ecological framework for understanding the structure of organisms in different sorghum cropping agrosystems in Honduras and the U.S. Collaborations also took place in Sudan and Malawi.
1.Determine host plant ovipositional preferences of S. latifascia and S.frugiperda, two armyworm species in the langosta complex. 2.Determine host piant feeding preference of S. latifascia and S.frugiperda. 3.Determine feeding performance of Metaponpneumata rogenhoferi, a third species in the langosta complex, and S. frugiperda. 4.Determine larval feeding induction (induced feeding on host plants) with S.frugiperda, S. latifascia and M. rogenhoferi. 5.Identify sorghum with resistance to fall armyworm and determine mechanism of resistance. 6. Observe flight and oviposition behavior of S. frugiperda. Development of pest management tactics.
