Aphid body size measurement
The body size and body color of A. gossypii varied greatly on
suitable and unsuitable host plant, and nymphs of A. gossypiideveloped into adults in about 6 d, and then did not increase in body
size (Watt and Hales 1996). So, we measured aphid body length and wide
of the HI lineage in the life table experiments at age of 10 d under
binocular microscope (Nikon, Japan). Each treatment replicated 30
measurements.
