Cophylogenetic relationships between Anicetus parasitoids (Hymenoptera: Encyrtidae) and their scale insect hosts (Hemiptera: Coccidae)

摘要: Numerous studies have investigated cospeciation between parasites and their hosts, but there been few concerning parasitoids insect hosts. The high diversity host specialization observed in Anicetus species suggest that speciation adaptive radiation might take place with diversification scale Here we examined the evolutionary history of association hosts via distance-based tree-based methods. A total 94 individuals (nine parasitoid species) 113 (seven from 14 provinces China were collected present study. DNA sequence data a mitochondrial gene (COI) nuclear ribosomal (28S D2 region) used to reconstruct phylogenies analysis showed significant fit analyses suggested this signal could be only when cost host-switching was high, indicating presence parasite sorting on related species. This study, based extensive rearing identification, provides strong evidence for prevalence events specificity genus Anicetus, offering insights into process parasitizing insects.
