Life History - Developmental times from egg deposition to adult emergence appears to be primarily controlled by temperature, humidity, and host plant. These times will vary from 16 to 38 days depending on these factors. The number of eggs laid by each female over her lifetime varies considerably, but appears to be around 80 to 100. Apparently at temperatures above 36 degrees C, eggs fail to hatch. They tuck their legs and antennae underneath and settle down closely to the leaf surface.
Crawlers molt into scale-like nymphs that also suck out sap.
Nymphs molt a second and third time. The fourth stage eventually becomes a nonfeeding pupa. The adult whitefly develops within the pupa. Adults emerge from the pupa through a T-shaped slit about a month from the time the egg was laid. Females live about 2 weeks.
