Abstract
The population dynamics of Corecoris dentiventris adults was studied at an experimental tobacco plot in Porto Alegre, Brazil (30º 01'S 51º 13'WGR), by the mark-release-recapture method. In an area of ca. 300 (3 are) m², 365 tobacco plants were grown. From August/1997 to February/1998, all plants were inspected weekly. Adults were captured by hand, marked with coded dots on the elitra with a permanent ink pen and released back on the same plant. Data was analyzed by the Fisher-Ford method. Two hundred seventy three bugs were marked on 45 sampling occasions. Recapture rates were extremely high, about 41 and 40% for females and males respectively. Daily survival rate estimates were above 96%. Population size was about 60 individuals in the 1st generation, reaching a plateau higher than 100 in the 2nd generation. Estimated mean minimum longevity was 25,19 +/- 2,21 and 22,9 +/- 3,54 for females and males respectively.Downloads
