<em>Bemisia tabaci</em> (Gennadius) is an important pest on horticultural crops that can also become a vector of <em>Geminivirus</em> that transmit the yellow curl disease.<em> B. tabaci</em> can also attack weeds that grow around the field such as <em>Ageratum conyzoides</em> or goatweed. The objective of this research was to study the life cycle, life time, fecundity, and reproduction rate of <em>B. tabaci</em> on chili pepper and goatweed. The experiment was conducted by observing the development of 50 eggs into adulthood. All 50 eggs were put on one plant and repeated 3 times. The plants were grown at temperatures 25 °C and 29 °C inside growth chamber (L : D = 12 : 12). The result of this experiments showed that at both temperatures of 25 °C and 29 °C, reproductive rate (R0), intrinsic rate of increase (r) and fecundity of <em>B. tabaci</em> were higher on goatweed than chili pepper. This implies that the existence of goatweed around chili pepper in the field can serve as a good alternative host for <em>B. tabaci</em>, hereby supporting the pest population even further.
