Thomas, A., & Ramamurthy, V.V. 2014 Morphological and Molecular Studies on the Intraspecific Variations Between Populations of the Cotton Mealybug Phenacoccus solenopsis Tinsley (Hemiptera: Pseudococcidae). Entomological News 123(5): 339-347
Notes: The intraspecific variations in the morphology of populations of cotton mealybug Phenacoccus solenopsis Tinsley (Pseudococcidae: Hemiptera) from cotton, okra and hibiscus were analyzed. Genetic diversity in the populations using mitochondrial cytochrome oxidase 1 (mtCO-1) sequences revealed that there were no significant variations of P. solenopsis collected from various hosts in Asia. However, the phylogenetic tree with available sequences in the NCBI GenBank of different geographic regions revealed a distinct separation between Asian and American populations.
