Abstract: A formulation containing 1% deltamethrin was tested for efficacy against the sheep body louse. It was applied as a back-line treatment at a rate of 1 m1/5 kg bodyweight (2 mg/kg) to sheep either immediately after shearing or 3 weeks later. The formulation killed all observable lice within a day when applied off-shears to sheep which were subsequently confined overnight. When sheep were treated 3 weeks after shearing, and not subsequently confined, all lice were killed within 2–7 days. About 10 weeks protection from reinfestation was provided by off-shears treatment, and about 15 weeks by treatment 3 weeks after shearing. Breakdown in protection occurred when deltamethrin levels in the wool fell to about 1 ?g/g greasy wool. Although the results suggest high efficacy, residue data indicate that the spread of insecticide was much less even than with plunge dipping in deltamethrin. A method for determining deltamethrin levels in wool is recorded. |

No studies have examined the invasion of exotic species used for forestry purposes in the savannas of the Brazilian Amazonia.; Aims : We investigated the invasion process of Acacia mangium in savanna areas adjacent to large-scale forestry plantations in north-eastern Roraima State, Brazilian Amazonia.; Methods : A tree inventory to record the presence of all A. mangium and native tree individuals was carried out in of 14 plots (each 50 m in width and 1500 m in length) established at five plantation sites. Biometric measurements were taken for all individuals to identify their structure and maturity. Distance categories were created for determining frequency of occurrence in 100 m sections along the plots for all individuals. Correlations and goodness-of-fit tests for discrete data ordered in categories were applied to verify the occurrence of A. mangium plants in relation to distance from the plantation.; Results : Individuals of A. mangium were dispersed up to 900 m from the plantation edge 8?9 years after the plantation was established. Although most recorded individuals were in the juvenile stage, reproductive adults were found in two establishment patterns: non-nucleated and nucleated under native tree species. Crown cover of the savanna's most abundant native tree species facilitated the regeneration of A. mangium.; Conclusions : Planting of A. mangium in Amazonian savannas provides a source of continuous dispersal, and invasion by the species is facilitated by environmental conditions.
