| Abstract | Honey bee brood tests under semi-field conditions are higher-tier studies for investigating the potential impact of pesticides on brood development in honey bee colonies. Semi-field studies on the effects of pesticides on honey bees have been mainly carried out in the EU and USA, with only a relatively small number conducted in Korea and other Asian countries. Here, we report the first semi-field test in Korea, which was carried out from April to May 2016. The experiment included three treatment groups (control and two toxic reference chemicals), each with three replicate tunnels. The honey bee colonies were placed in tunnels covering 70 m$^{2}$ and containing Brassica napus. Flight activity, mortality, the condition of the colonies, and brood development were assessed during the 28 days of testing period. The toxic reference treatments were 400 g dimethoate a.i./ha and 600 g diflubenzuron a.i./ha. Brood termination rates for marked eggs were 31.3% in the control group, 83.5 and 68.0% for dimethoate and diflubenzuron, respectively. These results confirm the sensitivity of the test method and indicate that these two chemicals could be used as appropriate toxic reference compounds in future semi-field tests in Korea. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
