abstract
A survey of ectoparasites from 219 meadowlarks conducted during 2 consecutive fall-winter periods in a coastal prairie found immature Amblyomma maculatum Koch to be the most abundant parasite. Peak larval infestations occurred in December with 80-100% of collected birds infested and with a monthly mean of up to 34 larvae per bird. Peak nymphal infestations occurred in February or March with 95-100% of birds infested and with a monthly mean of up to 11 nymphs per bird. Seasonal dynamics of these stages offered possible insight into the persistence of A. maculatum in an area long infested with the red imported fire ant, Solenopsis invicta Buren. Four other species of ticks also were collected but in substantially lower numbers; Amblyomma cajennense (F.), Amblyomma inornatum (Banks), Haemaphysalis chordeilus (Packard), and Haemaphysalis leporispalustris (Packard). This appears to be the 1st host record of A. cajennense from meadowlarks. A collection of 17 northern bobwhite quail indicated that most of these birds were infested with A. maculatum but at a lower level than meadowlarks. The collections of 2 species of Mallophaga from meadowlarks and 4 species from the northern bobwhite quail are discussed.
