Comparative analyses revealed that E. formosa populations reared on S. sonchifolius exhibited significantly larger morphological dimensions (head width, body length, and hind tibia length) than those on N. tabacum. Wasps reared on S. sonchifolius demonstrated superior reproductive performance, showing significantly higher values in total egg load, mature egg count, and mature egg proportion upon emergence. Notably, their ovariole number averaged 9.12, significantly exceeding the 7.92 observed in N. tabacum-reared populations, with 42.00% of individuals possessing >9 ovarioles compared to only 14.00% in the N. tabacum-reared group. A strong positive correlation was identified between body size and total egg load at emergence in both groups (R=0.91 for S. sonchifolius, R=0.90 for N. tabacum). These findings suggest that that the enhanced parasitic potential of E. formosa reared on S. sonchifolius stems from its advantages in both morphological development and reproductive capacity. keywords:Encarsia formosa  Smallanthus sonchifolius  Nicotiana tabacum  reproductive potential  oogenesis View Full Text  View/Add Comment  Download reader
