Effect of host insect-host plant associations on selected fitness components of Encarsia formosa (Gahan) (Hymenoptera: Aphelinidae)

The hind tibial length in Encarsia formosa decreased when switched from Trialeurodes vaporariorum as a host on tobacco, to Bemisia tabaci as a host on poinsettias.

Based on new data we expected that there would be not such a problem. This pap...
