Propolis production by differents methods
The goal of the study was to investigate the propolis production by differents methods (“intelligent” collector of propolis - CPI, plastic screen and scratching). Fifteen beehives of Apis mellifera africanizated were padronizated, being five beehives for each collector type. Propolis production was evaluated monthly, to May 2005 to April 2006. The results show that the means monthly propolis production not have statically difference among the CPI (114.870.6 g), plastic screen (120.949.8 g) and scratching (85.749.2 g). With respect to seasonality effect on the propolis production, in the spring season, the plastic screen showed significant differences (176.754.8 g) with relation to CPI (68.217.1 g) and scratching (42.813.3 g). In the autumn season, the CPI showed significative propolis production (212.947.7 g) in comparison with the plastic screen (87.56.0 g). The others seasons do not have significant differences on the propolis production. The monthly medium temperature (oC), precipitation pluviometer (mm), relative humidity of the air (%), heatstroke (hours) and speed of the wind (km/h), in the studied period, do not present correlation with the propolis production of the collectors. Its may conclude that the propolis production was not influenced by collector used (CPI, plastic screen and it scratching) and the seasonality interferes in the propolis production.
