Abstract

The present study reveals the chromosome of 4 aphids species found on four common plants with medicinal properties. These aphids species are, Macrosiphum euphorbiae (Thomas) with diploid chromosome numbers 2n = 10 infesting on Malva parviflora, Myzus ornatus Liang having diploid chromosome numbers 2n = 12 infesting Ajuga bracteosa, M. ascalonicus Doncaster with chromosome numbers 2n = 12, on host plant Dahlia pinnata and Toxoptera odinae (van der Goot) with diploid chromosome numbers 2n = 8 infesting Duranta erecta. The actual lengths, relative lengths as well as Total complement length of the chromosome were measured at metaphase. Karyotypes were prepared and Idiograms were constructed based on relative lengths data.
