| Popis: | The giant honey bees Apis dorsata and Apis laboriosa construct nests of different shapes and sizes. A method was required to compare the shapes and sizes of these nests. We developed a nest shape index (NSI). It presents the ratio of the dimension of the upper horizontal attachment of the nest base (B), to the vertical dimension of the nest (V); NSI = B/V. We examined the NSI of A. dorsata nests. The results varied; NSI = 0.6–4.7. The shape of nests under a sloped support is characterized by the inclination index (II). This index presents the ratio of the vertical dimension of the nest (V) to the dimension perpendicular to the sloped base (P). The inclination index of the nests observed by us, varied; II = 1.2–3.0. The mean shape of A. laboriosa was NSI = 0.96. The difference between the NSI of A. dorsata and A. laboriosa is due to environmental conditions. These indexes make it possible to compare the shapes of different sized nests when real nests were measured or from measurement of nests in photograph... |
