Pekarcik, Adrian (2016-12-19)

The sugarcane aphid, Melanaphis sacchari (Zehntner), emerged as a new pest of sorghum in Texas and Louisiana in 2013, and has since spread rapidly throughout the Southern United States. Management of sugarcane aphid is ...

Chemical Ecology of Some Underexplored Aspects of Plant-Herbivore-Parasitoid Tritrophic Interactions

Morawo, Tolulope (2017-11-28)

Plants, herbivorous insects and their natural enemies are involved in an intricate tritrophic interaction in a complex chemical environment. Herbivore infested plants, as well as plant-fed herbivores release volatile organic ...

Cotton Stalk Management and Cover Crop Use on CLRDV Incidence and Soil Properties

Frazier, Samuel (2023-07-10)

Cotton leafroll dwarf virus (CLRDV) was reported in cotton (Gossypium hirsutum L.) in Alabama in 2017. CLRDV can now be found as far west as Texas, and as north as Virginia. Due to such wide distribution and potential yield ...

Creation of an Infectious Clone of Cotton leafroll dwarf virus (CLRDV), a fluorescent clone of CLRDV, and the transmission determinants of CLRDV by Aphis gossypii

Clark, Wilson (2023-07-25) ETD File Embargoed

Cotton leafroll dwarf virus is an emerging pathogen in the United States. This disease has caused significant damage to the cotton (Gossypium hirsutum L.) production in other countries. In order to avoid these significant ...
