Rna Interference: Potato/Tomato Psyllid, Bactericera Cockerelli, Oral Delivery Of Double-Stranded Rnai Construct, Bijaya Kumar Sharma
Biology Theses
The potato/tomato psyllid, Bactericera cockerelli (Sulc.), is a serious and economically important pest of the potato, tomato and other solanaceous crops. This insect is the putative primary vector of the phytopathogenic bacterium Candidatus Liberibacter solanacearum which causes the Zebra Chip in potato. This disease has caused millions of dollars loss to the potato industry. While traditional management programs have minimized the negative impacts of this disease system, a sustainable alternative to chemical treatment is needed. Management of this pest by downregulation of endogenous mRNA using RNA interference (RNAi) technology is one of the best molecular method available; however, several technical …
Bactericera Cockerelli (Sulc) (Hemiptera: Triozidae): Nearly Complete Mitochondrial Genome, Single Mitochondrial Genes And Complete Mitochondrial Genome Comparison, And Insecticide Resistance Genes Of Potato Psyllid Populations From North America, Amalia Rosa Lopez Montiel
Biology Theses
The potato psyllid, Bactericera cockerelli (Sulc.), is an economic pest of potatoes and other solanaceous crops, and the vector of the causal agent of zebra chip disease. The expanded distribution of the potato psyllid has resulted in the differentiation of biotypes (central and western), and haplotypes (southwestern and northwestern), according to analysis of the mitochondrial gene cytochrome oxidase I (COI). In this study, the nearly complete (part of the control region unsequenced) mitochondrial genome from potato psyllid populations occurring in North America: Texas, Nebraska, California, Washington, northwest (Washington) and southwest (Arizona), were sequenced using next generation sequencing technology. The raw …
Bactericera Cockerelli: Range Expansion, Candidatus Liberibacter Solanacaerum Detection, And Microbial Community Analysis, Alex Arp
Biology Theses
The potato psyllid (Bactericera cockerelli) is an emerging pest of solanacious crops. Traditionally their range expanded from Guatemala north through the central United States and into southern California. Recent expansions have led to potato psyllids residing as far south as Nicaragua and as for north as Washington State. Potato psyllids were also accidentally imported into New Zealand. These expansions are alarming because potato psyllids transmit Candidatus Liberibacter solanacaerum (Lso), the bacteria associated with Zebra Chip disease in potato, which results in millions of dollars in damages annually. In this study, potato psyllid and Zebra Chip range expansion into Central America …
