Abstract:
Knowledge of the diversity and occurrence of termites is a spring-board for environmental
management but the diversity and occurrence of termites is unknown not only in Bahir Dar but
also in Ethiopia. The objective of this study was to identify termite taxa and determine the
diversity and distribution of termites at different habitats in Bahir Dar area. Data were collected
for eight months starting from December 2016 to July 2017. Termites were collected from their
natural habitats using maize stalks as baits. The results showed that a total of over 16,000 termite
individuals which consists of one family (Termitidae), two subfamilies, i.e. (Macrotermitinae
and Termitinae), five genera (Macrotermes, Odontotermes, Microtermes, Amitermes and
Microcerotermes) were found. Microtermes followed by Macroterme had more termite
individuals than other genera. Microcerotermes were rare while Macrotermitinae were more
abundant. Shannon’s diversity index and Simpson's index of diversity values appeared to be higher
in the protected vegetation. The distribution of termites in the different habitats showed that
protected vegetation had higher number of genera (five genera), followed by grass and cultivated
lands (four genera) each. Termite Populations were significantly higher during the rainy season.
The genus Odontoterme occurred more during the dry season than the wet, indicating its
foraging behavior on dry ground. Seasons, habitats and weather variables were the main factors
guiding the distribution and abundance of termites in the study area.
