The role of calcium in the regulation of Xylella fastidiosa virulence
(2013-12-03)
The Gram-negative plant pathogenic bacterium Xylella fastidiosa inhabits the xylem vessels of the host, where it forms biofilms thought to be responsible for disease symptoms. Even though knowledge regarding the mechanism ...
Behavioral Responses of Two Parasitic Wasp Species with Different Degree of Host Specificity to Host-Related Plant Volatiles
(2013-11-08)
As an indirect defense to herbivore attack, plants release many types of volatile organic compounds (VOCs), which guide parasitoids to their herbivore hosts. Plants may release constitutive volatiles or synthesize new ones ...
Visual, Acoustic, and Volatile Cues to Improve Performance of Trapping Ambrosia Beetles (Coleoptera: Curculionidae)
(2013-11-11)
Three widely distributed species of ambrosia beetles (Coleoptera: Curculionidae: Scolytinae), Xylosandrus germanus Blandford, Xylosandrus crassiusculus Motschulsky, and Cnestus mutilatus Blandford are introduced pests that ...
Multiple Mechanisms of Permethrin Resistance in the Southern House Mosquito, Culex quinquefasciatus
(2013-07-18)
The inherited resistance to permethrin in Culex quinquefasciatus, which is the primary vector of encephalitis and lymphatic filariasis pathogens, resulted from the molecular basis of multiple mechanisms involved in changes ...
Respiratory Physiology of Urban Insects

Cytochrome P450s and Their Roles in Insecticide Resistance in the Mosquito, Culex quinquefasciatus
(2013-07-24)
The southern house mosquito, Culex quinquefasciatus, is an important disease vector of West Nile virus (WNV), Saint Louis encephalitis virus (SLEV), and filariasis. Insecticides are the most important component in the ...
Integrated management of sheath blight of rice by fertilizers, fungicides, and plant growth-promoting rhizobacteria
(2013-04-22)
Sheath blight (ShB) is a soilborne disease causing major economic losses to rice cultivation. The disease is caused by a soil living basidiomycote fungal pathogen, Rhizoctonia solani Kuhn. Reliable and effective disease ...
