Bot fly larvae (Philornis genus) are obligate subcutaneous blood-feeding parasites of Neotropical birds including psittacines. We analyze twelve years of data on scarlet macaw (Ara macao) nestlings in natural and artificial nests in the lowland forests of southeastern Peru and report prevalence and intensity of Philornis parasitism. Bot fly prevalence was 28.9% while mean intensity was 5.0 larvae per infected chick. Prevalence in natural nests (11%, N=90 nestlings) was lower than in wooden nest-boxes (39%, N=57) and PVC boxes (39%, N=109). We describe a new technique of removing Philornis larvae using a reverse syringe design snake bite extractor. We compare this new technique to two other methods for removing bots from macaw chicks and find the new method the most suitable.
狂蝇幼虫（Philornis 属）是新热带鸟类（包括凤头鹦鹉）专性皮下吸血寄生虫。我们分析了 12 年来在秘鲁东南部低地森林中自然和人工巢穴中猩红金刚鹦鹉雏鸟的数据，并报告了狂蝇寄生的流行率和强度。狂蝇的流行率为 28.9%，平均每只感染雏鸟有 5.0 条幼虫。自然巢中的流行率（11%，90 只雏鸟）低于木制巢箱（39%，57 只）和 PVC 箱（39%，109 只）。我们描述了一种使用反向注射器设计的蛇咬提取器去除狂蝇幼虫的新技术。我们将这种新技术与从金刚鹦鹉雏鸟中去除狂蝇的另外两种方法进行了比较，发现这种新方法最适用。
