VL - 47 IS - 2 SE - Articles DO - 10.4314/tjs.v47i2.17 UR - https://tjs.udsm.ac.tz/index.php/tjs/article/view/657 SP - 616-624 AB - <p>The study was conducted in Afaka, Northern Guinea Savanna of Nigeria to determine the spatial distribution patterns of the populations of <em>Ancistrotermes</em> sp. and <em>Microtermes</em> sp. in <em>Eucalyptus camaldulensis</em> Dehnh, <em>Eucalyptus citriodora</em> Hook, <em>Eucalyptus cloeziana</em> F. and<em> Eucalyptus tereticornis</em> Muell plantations. Spatial distributions patterns of the two termite species populations were determined using indices such as ratios of population variance to mean, Lloyd’s index, Green coefficient, Taylor power and Iwao’s regression models. The values of variance to mean ratios, Lloyd’s index and Green coefficient showed that the populations of both termite species had aggregated distribution pattern in all the <em>Eucalyptus</em> species plantations. The distribution patterns of <em>Ancistrotermes</em> and Microtermes differed using Taylor’s and Iwao regression models. The values of R2 in Taylor’s model ranged from 0.02 to 0.99 for <em>Ancistrotermes</em> sp. and 0.29 to 0.99 for <em>Microtermes</em> sp., while in Iwao’s model, R2 ranged from 0.10 to 0.96 for <em>Ancistrotermes</em> sp. and 0.08 to 0.98 for <em>Microtermes</em> sp. The information provided is vital to develop a sound pest management protocol for these termite species.</p><p><strong>Keywords</strong>: Spatial distribution, <em>Ancistrotermes</em> sp., <em>Microtermes</em> sp., Aggregated, Taylor’s model, Iwao’s model</p> ER -
