| dc.description.abstract | Two Brazilian isolates and one Benin (indigenous) isolate of Neozygites floridana were released against the cassava green mite, Mononychellus tanajoa , in January 1999 in the Adjohoun district, Ouémé administrative region, Republic of Benin. Post-release monitoring conducted 8, 14, 22 and 36 weeks later showed very low mean infection rates on M. tanajoa by isolate (0.03-0.4%). However, 48 weeks after releases, mean infection rates increased noticeably to between 2.3 and 18.7%, and higher infection rates were observed for the Brazilian isolates compared with the indigenous one. The highest infection rate for the indigenous isolate was 4.5% while it reached over 30% for the Brazilian isolates (36.5 and 34.0%). Observations made to study dispersal from inoculated plants showed the absence of infected mites at 4 m from the inoculated plants in all fields 8 weeks after the releases, while they were already present on those at 2 m away. From the next monitoring, 14 weeks after the releases, infection was found at all three sampling positions (inoculated plants and plants at 2 and 4 m away). Only four mites with resting spores were found in over 460 000 mites examined. The highest infection levels were observed in December during 'harmattan' a period characterized by hot days and cool nights with high relative humidity. |
