Impact of Fungal Endophyte Colonization of Maize ( L.) on Induced Resistance to Thrips- and Aphid-Transmitted Viruses.

In eastern Africa, Maize lethal necrosis (MLN) is caused by the co-infection of maize plants with (MCMV) (Tombusviridae: ) and (SCMV) (Potyviridae: ). With the disease being new to Africa, minimal effective management strategies exist against it. This study examined the potential of 10 fungal isolates to colonize maize plants and induce resistance against MCMV and SCMV.

Effects of molasses grass, Melinis minutiflora volatiles on the foraging behavior of the cereal stemborer parasitoid, Cotesia sesamiae.

Olfactory responses of the cereal stemborer parasitoid Cotesia sesamiae to volatiles emitted by gramineous host and nonhost plants of the stemborers were studied in a Y-tube olfactometer. The host plants were maize (Zea mays) and sorghum (Sorghum bicolor), while the nonhost plant was molasses grass (Melinis minutiflora). In single-choice tests, females of C.
