Distribution of biting Culex tritaeniorhynchus (Diptera: Culicidae) among pigs: effects of host size and behavior.

摘要: The distribution of biting Culex tritaeniorhynchus Giles females among pigs was analyzed to determine the effect host size and behavior on selection by mosquitoes. number Cx. collected per sow significantly greater than that her piglets. Sleeping piglets were attacked more frequently mosquitoes wakeful ones. different-sized aggregated compared with expected random distribution, one four data sets showed significant size-dependence. Pig activity (including mosquito defensive behavior) reduced attacking mosquitoes, but total pig score not related counts during early half night or entire night. Data residence times indicated interrupted (and consequently multiple feedings) frequent. effects size-dependent (age-dependent) amplification Japanese encephalitis virus discussed in relation control programs.
