Sesamia nonagrioides (Lef.) is a major insect pest of sugarcane in southwestern Iran. It also damages maize and rice in this area. Using bacterial pathogens of insects as a biological control agent in an IPM program could be advantageous. In this study, the bacterial flora of S. nonagrioides were investigated in dead larvae with appearance of some bacterial disease. Samples were collected from ...

Insect double-stranded (ds)RNA expression in transgenic crops can increase plant resistance to biotic stress; however, creating transgenic crops to defend against every insect pest is impractical. Arabidopsis Mob1A is required for organ growth and reproduction. When Arabidopsis roots were soaked in dsMob1A, the root lengths and numbers were significantly suppressed and plants could not bolt or ...
