| are phenacoccus solani ferris and p. defectus ferris (hemiptera: pseudococcidae) distinct species? | among the nearctic species of phenacoccus (hemiptera: pseudococcidae), phenacoccus solani ferris and p. defectus ferris are morphologically similar and it can be difficult to separate them on the basis of microscopic morphological characters of the adult female alone. in order to resolve their identity, a canonical variates morphological analysis of 199 specimens from different geographical origins and host plants and a molecular analysis of the coi and 28s genes were performed. the morphologica ... | 2016 | 27394512 |
