Abundance and Spatial Dispersion of Rice Stem Borer Species in Kahama, Tanzania.
Bottom Line: Stem borers dispersion was aggregated along the edges of rice fields in three locations (wards) namely: Bulige, Chela, and Ngaya.The dispersion in the fourth ward, Kashishi was uniform as established from two of the three dispersion indices tested.Further studies would be required to establish the available alternative hosts, the extent of economic losses and the distribution of rice stem borers in the rest of the Lake zone of Tanzania.

Mentions: In all of four study locations, stem borer larvae were more aggregated along the edges of rice fields than in the middle parts (Fig. 2). Among these wards, Chela had the highest number of larvae followed by Ngaya and Kashishi while Bulige had the lowest (Fig. 2).Fig. 2.
