Preliminary diversity study of bemisia tabaci (Gennadius) biotypes in Luzon, Philippines
Issue Date

Abstract
Bemisia tabaci (Gennadius), commonly known as silverleaf whitefly, is among the most notorious insect pests worldwide because of its wide host range (e.g. banana, cotton, solanaceous vegetables, cucurbits, root crops, legumes, onions, and tobacco) and its ability to transmit numerous types of plant pathogenic viruses. B. tabaci exhibits high genetic variability among populations but without obvious distinct phenotypic differences. Several studies suggested the presence of 11-44 biotypes of this species. In this study, a cladogram base on cytochrome oxidase I (COI) fragment of Philippine B. tabaci samples was constructed. Out of the 24 low-level groups reported by de Barro et al. in 2011, four (4) biotypes were detected in Luzon (Laguna, Bicol, Cavite, and Baguio). These biotypes were MEAM 1, ASIA 1, AUS (Australian) and ASIA II 6. Another biotype referred to as ASIA II 10, is an addition to the local biotype list. This study provides preliminary baseline information on B. tabaci biotypes occurring in the Philippines which is vital for the development of an efficient pest management strategy. Continuous sampling and processing are done to cover more areas around the country.
