Abstract: | The spatial distribution of the eggs, larvae, pupae and adults of the wheat-bulb fly was investigated by fitting 42 sets of data comprising 1334 samples to the Poisson and negative binomial distributions, and by using the power law (S2=amb). In general, the tests indicated that all stages were aggregated and fitted the negative binomial model. |
