Functional Response, Prey Stage Preference, and Mutual Interference of the Tamarixia triozae (Hymenoptera: Eulophidae) on Tomato and Bell Pepper.

The potato psyllid, Bactericera cockerelli (šulc), has been detrimental to potato, tomato, and other solanaceous crop production in many countries. Management of B. cockerelli is dominated by frequent insecticide applications, but other approaches need consideration, including biological control.

Identification of a fourth haplotype of Bactericera cockerelli (Hemiptera: Triozidae) in the United States.

The potato psyllid, Bactericera cockerelli (Sulc) (Hemiptera: Triozidae), is a pest of potato and other solanaceous crops in North and Central America and New Zealand. Previous genotyping studies have demonstrated the presence of three different haplotypes of B. cockerelli in the United States corresponding to three geographical regions: Central, Western, and Northwestern.

Latent period and transmission of "Candidatus Liberibacter solanacearum" by the potato psyllid Bactericera cockerelli (Hemiptera: Triozidae).

"Candidatus Liberibacter solanacearum" (Lso) is an economically important pathogen of solanaceous crops and the putative causal agent of zebra chip disease of potato (Solanum tuberosum L.). This pathogen is transmitted to solanaceous species by the potato psyllid, Bactericera cockerelli (Šulc), but many aspects of the acquisition and transmission processes have yet to be elucidated.

"Candidatus Liberibacter solanacearum" titer over time in Bactericera cockerelli (Hemiptera: Triozidae) after acquisition from infected potato and tomato plants.

The potato psyllid, Bactericera cockerelli (Sulc) (Hemiptera: Triozidae) is a serious pest of potato and other solanaceous crops. B. cockerelli has been associated with the bacterium "Candidatus Liberibacter solanacearum" (Lso), the causal agent of zebra chip, a new and economically important disease of potato in the United States, Mexico, Central America, and New Zealand.

Short-term population redistribution of Pseudacteon tricuspis (Diptera: Phoridae) from point source releases.

There is a need for quantitative data on patterns and rates of movement of organisms to understand their movement behavior and predict their rates of spread. Opportunities for studying movement of biological control agents are presented during release programs. However, despite these opportunities, patterns and range of dispersal are often not considered.

Sampling and dynamics of Pseudacteon tricuspis (Diptera: Phoridae) in Louisiana.

The population dynamics of a fire ant (Solenopsis invicta Buren) parasitoid (Pseudacteon tricuspis Borgmeier) was studied in Louisiana. The objectives of this study were to understand the daily and seasonal population dynamics of P. tricuspis in the context of environmental variables, determine whether P.
