Induced Release of a Plant-Defense Volatile ‘Deceptively’ Attracts Insect Vectors to Plants Infected with a Bacterial Pathogen
TLDR
The results suggest that host selection behavior of D. citri may be modified by bacterial infection of plants, which alters release of specific headspace volatiles and plant nutritional contents. Expand
Transmission Parameters for Candidatus Liberibacter asiaticus by Asian Citrus Psyllid (Hemiptera: Psyllidae)
TLDR
Evaluated acquisition and inoculation efficiency of Candidatus Liberibacter asiaticus (Las), the pathogen associated with citrus huanglongbing (HLB) by the Asian citrus psyllid, Diaphorina citri (Kuwayama) is evaluated, indicating that adult D. citri which acquire the HLB pathogen as adults are poor vectors of the Pathogen compared with adults that acquired the pathogens as nymphs. Expand
Glutathione Transferase and Cytochrome P450 (General Oxidase) Activity Levels in Candidatus Liberibacter Asiaticus-Infected and Uninfected Asian Citrus Psyllid (Hemiptera: Psyllidae)
TLDR
Lower activities of GST and general oxidase in Las-infected D. citri indicate that infection with Las alters D.citri physiology in a manner that could increase insecticide susceptibility. Expand
Global gene expression changes in Candidatus Liberibacter asiaticus during the transmission in distinct hosts between plant and insect.
Huanglongbing (HLB) or citrus greening disease is a destructive disease of citrus worldwide, which is associated with Candidatus Liberibacter asiaticus. This phloem-limited fastidious pathogen isExpand
Effect of Candidatus Liberibacter asiaticus infection on susceptibility of Asian citrus psyllid, Diaphorina citri, to selected insecticides.
TLDR
Susceptibility of ACP to selected insecticides from five major chemistries was greater in Las-infected than in uninfected ACP; however, there was a general trend towards lower LC(50) values for three other insecticides for Las- infected ACP adults, although the differences were not statistically significant.

Plant pathogen-induced volatiles attract parasitoids to increase parasitism of an insect vector
TLDR
This is the first report of a parasitoid ‘eavesdropping’ on a plant volatile induced by bacterial pathogen infection, which also increases effectiveness of host seeking behavior of its herbivorous vector. Expand
Infection of an Insect Vector with a Bacterial Plant Pathogen Increases Its Propensity for Dispersal
TLDR
This study indicates that the phytopathogen, CLas, may manipulate movement and mate selection behavior of their vectors, which is a possible evolved mechanism to promote their own spread. Expand
Better Together: Association With ‘Candidatus Liberibacter Asiaticus’ Increases the Reproductive Fitness of Its Insect Vector, Diaphorina citri (Hemiptera: Liviidae)
TLDR
The survival of Las-infected adult D. citri was lower compared with uninfected D.citri, which suggests that there may be a fitness trade-off in response to Las infection, and a beneficial effect of a plant pathogen on vector fitness may indicate that the pathogen developed a relationship with the insect before secondarily moving to plants. Expand
Lack of Evidence for Transmission of 'Candidatus Liberibacter asiaticus' Through Citrus Seed Taken from Affected Fruit.
TLDR
This research was undertaken to provide evidence as to whether or not 'Ca. L. asiaticus' can be transmitted through seed, and found no evidence of transmission of the pathogen through seed. Expand
VERTICAL POSITION OF TRAPS INFLUENCES CAPTURES OF EASTERN CHERRY FRUIT FLY (DIPTERA: TEPHRITIDAE)
TLDR
The eastern cherry fruit fly, Rhagoletis cingulata, is an important late-season pest of cherries in the eastern and Midwestern United States and it was hypothesized that the height of trap placement within the cherry tree canopy would affect captures of R. cedulata on monitoring traps. Expand
