Online published on 30 April, 2019. Abstract Three species of pseudococcids viz., Phenacoccus solenopsis (Tinsley), Maconellicoccus hirsutus (Green), and Ferrisia virgata (Cockerell) were subjected to cytological investigations with cytological techniques. These revealed a configuration of 2n= 10 in both male and females with ‘Lecanoid type of genetic system’ and without any identifiable sex chromosomes. Differentially stained (Giemsa, C-banded, and AgNO3) female somatic chromosomal karyotypes were constructed for each of these species and used for comparison.
