Landscape heterogeneity and the host plant use are factors suggested to play determinant roles in shaping evolutionary history of herbivorous insects. However, role reconfiguration plants distributions linked Quaternary climate oscillations as drivers contemporary population genetic structure is still poorly understood. Here, we formally examine relative contribution such on intraspecific diver...

Long term trapping studies of the invasive moth Cactoblastis cactorum (Berg) were conducted at various latitudes from Puerto Rico to South Carolina. Three flight periods per year were identified at the 5 temperate sites studied, which covered the majority of the infested range on mainland United States. In general, the 3 flight periods across a latitudinal gradient from south Florida to central...

Abstract Phytophthora is a genus of plant pathogens that infects vegetables, crops, ornamentals, and trees. diseases in soil are facilitated by the rapid dispersal zoospores, which come two different forms, is, motile biflagellate zoospores nonmotile encysted zoospores. However, little known about mechanisms controlling zoospore dispersal, especially under unsaturated flow natural soil. Hence, ...
