저번 호에는 꿀벌봉군붕괴현상(CCD)의 원인들에 대하여 고찰하였습니다. 미국, 호주 그리고 유럽국가에서 보고된 내용을 보면 벌들의 탈출현상은 매우 다양한 이유에 의해서 생겨났음을 여러분도 쉽게 이해하셨을 것입니다. 한창 많은 벌들이 벌통 안에서 식구를 늘려가야 제때에 채밀에 성공할 수 있는데 벌이 사라져 없으니 기막힌 사실이 된 것입니다. 냉정한 마음으로 깊이 생각할 필요가 있다고 봅니다. 다행이 우리나라는 미국, 유럽처럼 아직 심각한 정도는 아닙니다. 그러나 우리나라에서도 진행되고 있다는 사실이 나타나고 있다고 말씀드린 바 있습니다. 1992년 중국에서 꿀벌이 수입 되었을 때 처음으로 중국가시응애가 묻어와 우리 양봉산업이 위기를 맞기도 하였습니다. 조사된 피해수준은 전체 봉군의 30~70%가 붕괴되었습니다. 꿀벌응애와 중국가시응애, 부저병, 백묵병과 노제마병은 전국 어느 곳 양봉장에서도 발생하였습니다. 좁은 벌통 안에서 여러 가지 질병이 연속적으로 꿀벌을 괴롭힌 것입니다. 미국의 경우 화분매개용 봉군은 개화시기에 맞추어 먼 곳까지 이동해야 하므로 벌은 스트레스를 받는다고 합니다. 스트레스가 원인이 되어 꿀벌의 붕괴가 생겨났다는 주장인데 많은 분들이 그럴 것으로 수긍하고 있습니다. 이와 같은 스트레스는 위에서 언급한 응애와 여러 질병이 발생하여 꿀벌이 겪어야 하는 고통에 비교하면 훨씬 낮은 스트레스라 생각합니다.

Residual toxicity test to honeybee was conducted to evaluate an indirect effects on honeybee after planting hole application of systemic insecticides which were highly toxic to honeybee (Apis mellifera). In this study, It was applied three application rates in the planting hole by three systemic insecticides, dinotefuran GR, imidacloprid GR and clothianidin GR at planting time of tomato. Residual analysis of foliage was carried out after periodic sampling the foliage and investigated the effects of exposed honeybee on the tomato foliage. The honeybee mortality by dinotefuran residues on the foliage was shown almost 100% at 7 days after treatment and decreased 17 days after treatment. The maximum mortality of honeybee by imidacloprid residues on the foliage was 44 ~ 72%. But the effect of pesticide lasted for 18 days and then decreased. The honeybee mortality by clothianidin residues on the foliage was 100% at 7 days after treatment and decreased 14 days after treatment. A tendency of the honeybee mortality and residue in foliage showed a similar character as time goes by. The residues in tomato foliage decreased gradually after 14 days by vigorous growth of tomatoes and the toxic effect of honeybee was significantly decreased after 21 days in actual usage of the treatment.

Recently, rapid climate change has had a significant impact on the bee ecosystem. The decrease in the number of bees and the change in the flowering period have a huge impact on the harvesting of beekeepers. Accordingly, attention is focused on smart beekeeping, which introduces IoT technology to beekeeping. According to the characteristics of beekeeping, it is impossible to continuously observe the beehive in the hive with the naked eye, and the condition of the hive is mostly dependent on knowledge from experience. Although a system that can measure partly through sensors such as temperature/humidity change inside the hive and measurement of the amount of CO2 is applied, there is no research on measuring the movement path and amount of movement of bees inside the beehive. Part of the migration of honeybees inside the hive can provide basic information to predict the most important cleavage time in beekeeping. In this study, we propose a device that detects the movement path of bees and measures and records data entering and exiting the hive in real time. The device proposed in this study was developed according to the honeycomb standard of the existing beehive so that beekeeping farms could use it. The development method used a photodetector that can detect the movement of bees to configure 16 movement paths and to detect the movement of bees in real time. If the measured honeybee movement status is utilized, the problem of directly observing the colony with the naked eye in order not to miss the swarming time can be solved.

서양뒤영벌(Bombus terrestis)과 꿀벌(Apis melltfera)의 시설참외에서 화분 매개특성을 조사한 결과, 봉종별 방화활동에서 서양뒤영벌 일벌은 10시, 서양뒤영벌 수벌과 꿀벌은 12시에 방화활동 정점에 도달하였다. 암꽃 선호시간은 서양뒤영벌 일벌, 꿀벌 그리고 서양뒤영벌 수벌은 각각 10시, 12시 그리고 14-16시에 가장 높았다. 봉군 투입 후 서양뒤영벌 일벌과 꿀벌은 각각 2일과 5일째부터 정상적인 방화활동을 시작하여 24일간 정상적인 활동을 하였으나 서양뒤영벌 수벌은 3차례의 심한 기복이 있는 불안정한 방화활동을 보였다.

최근 꿀벌 집단 실종이 잇따라 발생하고 있으며 이에 대한 뚜렷한 원인은 없으나 꿀벌응애류, 말벌류에 의한 폐사와 이상기후가 복합적으로 작용했기 때문이라고 추측하고 있다. 추측하고 있는 원인 중 꿀벌 봉군의 약화 요인으로 작용하는 등검은말벌의 분포도를 시각화하여 꿀벌의 개체 수 피해를 줄이는 데 도움이 되고자 한다.

This study examined the acaricidal activity of a new compound, K16776 against honeybee mite, Varroa destructor which is ecto-parasite of Apis mellifera. Acaricidal activity was performed using six acaricides, two Chinese commercial acaricides and one newly synthesized K16776 against V. destructor in the small container and in the bee hive. K16776 and amitraz exhibited 100% acaricidal activity against V. destructor without insecticidal toxicity to A. mellifera in the small container. The other acaricide was not activity. Applied to the bee hives, K16776 showed acaricidal activity as 98.7% ($250{\times}$) and 88.6% ($500{\times}$) and amitraz showed as 100% ($500{\times}$) and 90% ($1,000{\times}$), respectively. Made in China, Cao Suan Sha Man Pian and Wangs showed acaricidal activity as 56.9% and 66.7%, respectively. The result indicates that K16776 can be potentially useful control agent against honeybee mite, V. destructor.

Lack of honey bee toxicity data for most pesticide products used for strawberry restricts to predict the adverse effects to foraging honey bee after treatment of pesticide in plastic house. This study was conducted to evaluate the actual risk of worker honey bees (Apis mellifera L.) through acute contact toxicity test, acute oral toxicity test and toxicity of residues on foliage test with 21 pesticide products. The mortality of honeybee sprayed with 6 pesticides including dichlofluanid WP showed significantly different from control at recommended application rate in acute contact toxicity test at 24 hours after treatment. Fenpropathrin EC and milbemectin EC treatment groups showed more than 25% mortalities at recommended application rate in acute oral toxicity test. In toxicity of residues on foliage test, only fenpropathrin EC treatment group showed more than 25% mortalities at 10 days after treatment at recommended application rate. It was concluded that the most toxic route to exposure for honey bee is direct contact exposure to sprayed pesticides. Safety interval for honey bee was established by concerning the results of these tests.
