Seasonal variation of infestation by ectoparasitic chigger mite larvae (Acarina: Trombiculidae) on resident and migratory birds in coffee agroecosystems of Chiapas, Mexico

摘要: Parasitism is not well documented for birds found in tropical habitats. Long-distance migratory may face additional risks to an already hazardous journey when infected. This study explores the ecology of ectoparasite infestation Chiapas, Mexico. During a mist-netting project 2 different coffee management systems, chigger mites (Acarina: Trombiculidae), ectoparasitic during larval stage, were on both resident and birds. Using rapid assessment protocol, it was observed that 17 26 species long-distance migrants 33 71 had at least 1 infested individual. Infestation prevalences unexpectedly high some migrants, as 0.73 Swainson's thrush (Catharus ustulatus), value par with heavily species. Prevalence highest winter sampling: 0.18 overall, 0.16 0.23 residents. 0.14 summer breeding season. Mean abundance mean intensity are reported 97 captured inspected course this study. In region, mite larvae relatively common their varies seasonally. High prevalence suggests more research monitoring ectoparasites needed, especially light emerging diseases.
