The diversity of Apis cerana Fabr. in the Philippines was studied using morphometric methods. A
total of 101 samples of A. cerana from feral and hived colonies, and foragers were collected
throughout the Philippine archipelago. The 39 morphometric characters recommended by Ruttner and Ruttner
et al. were measured. The data were statistically analyzed by means of factor analysis, discriminant
analysis, and cluster analysis. The bees from Palawan were unequivocally distinct and separate from the
other Philippine samples. The bees from the other Philippine islands still showed a high degree of
variation. The bees of Luzon differed clearly from those of Visayas and Mindanao. Within Luzon, the bees
from the highland differed clearly from those in the lowland and were regarded as separate groups. Bees
from Visayas and Mindanao were still very variable and showed potential for further sub-structuring. The
present analysis could not distinguish whether the difference between Luzon and Visayas-Mindanao was based
on a north-south clinal structure, or on distinct groups.
