Foraging activities by bumblebee, Bombus terrestris S. (Hymenoptera: Apidae) at two cultivating types of cherry-tomato house

2가지 재배형의 방울토마토 하우스에서 서양뒤영벌의 방화활동

The foraging activities of bumblebee, Bombus terrestris were surveyed to compare with two types of cherry-tomato (Lycopersicon esculentum. M) house as Nutriculture and Sawdustculture on southern part of Korea in winter . The summary of the result obtained for this purpose are below: In the interval of blooming time from Sawdustculture type. In the interval of the time from the first visting on the flower by a worker of B. terrestris after a flower of cherry-tomato bloomed. nutriculture type was more shorter than Sawdustculture type. Therefore there was no difference in the average pollination time from the flower's blossoming according to the inflorescence of the first visiting time of B. terrestris worker on the each flower between Nutriculture type and Sawdustculture type. The foraging activites of B. terrestris worker in two kinds of cherry-tomatio cultivating house had shown same patterns. and han not been found to the differences.

겨울철 남부지방에서 2 종류의 방울토마토 재배하우스, 즉 양액 재배농가와 톱밥재배농가에서의 서양뒤영벌의 방화활동을 조사한결과, 개화간격은 양액 재배농가가 톱밥 재배농가보다 길었으나, 개화 후 일벌 방화까지의 시간은 양 액재배농가에서 톱밥재배농가보다 짧았다. 따라서 2 종류의 하우스에서 1개의 꽃이 개화하여 방화되기까지의 수정시간에는 차이가 없었다. 일벌들의 방화활동도 같은 양상을 유지하였으며, 투입된 벌의 방화활동 차이는 발견할 수 있었다.
