Interpretive Summary:

Technical Abstract: Does cotton leaf morphology influence the ability of the newly hatched whitefly crawler, to locate, penetrate, and reach phloem tissue in order to feed? Our earlier theory proposed that whiteflies feed and oviposit on the abaxial surface (underside) of leaves due to the closer proximity of phloem tissue to that leaf surface. The length of the stylet bundle at that time was believed to be 80 um. We have shown for both the silverleaf whitefly, Bemisia argentifolii, adults and nymphs that the length of the stylet is not a limiting factor.
