| Sumario: | <p>The whitefly <em>Bemisia tabaci</em> (Gennadius) biotype B also known as <em>Bemisia </em><em>argentifolii </em>(Gennadius) is a more malignant whitefly biotype in damaging plants compared to non-B biotype. Currently the whitefly <em>B. tabaci</em> biotype B has been reported to exist in Indonesia. Basic information such as life cycle, length of life, fecundity, and breeding ability of a whitefly is important information as a basis in preparing the whitefly control strategy. The aim of this research was to study the life cycle and demographic statistic of the <em>B. tabaci</em> biotype B and the non-B biotype on chili pepper. The study was conducted by observing the development of the whiteflies from eggs to adult in a growth chamber that the temperature and lighting were controlled. Observations were made on several aspects of biology and some parameters of demographic statistics. The results showed that the biotype B of <em>B. tabaci</em> has several different biological aspects with the non-B whitefly in chili pepper. The life cycle of the biotype B of <em>B. tabaci </em>and the non-B were different, 33.27 and 30.86 days respectively. The biotype B of <em>B. tabaci </em>had a net reproduction rate (R<sub>0</sub>) which was similar to that of the non-B biotype as well as the average of its generation. However, the intrinsic increase rate (r) of the biotype B <em>B. tabaci</em> was 2.5 times shorter than the non-B biotype. The biotype B of <em>B. tabaci </em>doubled its population (DT) 2 times faster than the non-B biotype. It is clear that the biotype B of <em>B. tabaci </em>potentially more dangerous than the non-B.</p> |
