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.

Bumblebees are widely used to pollinate crops in greenhouses and fields. Here we firstly developed an apparatus for the oviposition induction of the bumblebee Bombus ignitus using electricity. The apparatus consists of boxes for colony initiation, part of temperature control, part of heat transfer, and moving shelf. The result shows that the rates of oviposition and colony foundation in the newly developed apparatus are respectively 3.9% and 5.2% higher than in the existing apparatus using hot water. More importantly, the newly developed apparatus is 75% cheaper in costs and can more save energy than existing apparatus. These results indicate that the newly developed apparatus could serve as an effective apparatus for the oviposition induction of B. ignitus.

Web structure of spiders is a foraging strategy as well as an investment to get prey. In order to increase the fitness consequence, spiders change their foraging strategy based on sensory information provided by prey species. We conducted an experiment to demonstrate whether an orb-web building spider, Argiope bruennichi modifies its web-building behavior after experiencing sensory information emitted by a UV recognizing flying insect, Bombus terrestris. To know how the web structure would be modified, we observed web characteristics after providing sensory information of a potential prey species, the bumblebee (experimental group) and compared them to the control group (no information provided). We hypothesized that the spiders of the experimental group would increase investments in their web construction and stabilimentum decoration. The results rejected our hypothesis. Web and stabilimentum constructions decreased in the course of the experiment in both the control group and the experimental group. The individuals did not increase their stabilimentum length and did not extend their web areas, in spite of sensory information given by the nectar collector.

The multiple real-time PCRs against pathogens of Bombus species including DWV, IAPV, KBV, SBV, BQCV, kSBV, SBPV and Paenibacillus larvae, Mellisococcus plutonius, Lysinibacillus fusiformis, and Klebsiella oxytoca have been developed. One extracted nucleic acid from Beesample could be applied to 11 different PCRs in same time and condition. Specific PCR-products were amplified qualitative and quantitative manner inner 20 minutes successfully, when each 1000 molecules of pathogen-specific target DNA is existed as template, respectively. The multiple PCR detection that we propose would be expected to apply to quarantine test for international exchange of Bombus species.

This study was examined the characteristics on the pollinating activities of Apis mellifera, Bombus ignitus and B. terrestris as pollinators on the watermelon flowers(Citrullus vulgaris Schrad), and the effects of the pollination by pollinators compared to the artificial pollination in the watermelon green houses in Nonsan City on summer season in 2005. As a result, B. ignitus and B. terrestris could not be used for summer season, because the bumblebees were not pollinated effectively indeed even two days after hives were released at watermelon green houses during the summer cultivating period. It could not be controlled a poor watermelon house conditions; high temperature and low humidity on summer season which were the bad environment for pollinating activities of bumblebees. But this study was showed that A. mellifera could be used comparatively good pollinator instead of artificial pollination in spite of the bad environment for bee within the watermelon green houses on summer season.
