Monitoring and control options for broadbean seed beetle (Bruchus rufimanus) and other field bean (Vicia faba) pests Project leader Laura Ozoliņa-Pole Team of project Jānis Gailis Duration 2019 - 2022 Research focus 4. Development and adaptation of technologies for obtaining high-value agricultural and forest products, as well as in veterinary medicine Source of funding Ministry of Agriculture projects Project partners Dana Blese Description of project The aim of research To determine the effect of the broadbean seed beetle (Bruchus rufimanus) on field beans. To find out the dynamics of the broadbean seed beetle population and the factors influencing it (climatic factors, control methods, etc.). To evaluate different monitoring methods for determining the population density and flight activity of the broadbean seed beetle, based on which to determine more precisely, the most effective time of control the broadbean seed beetle. Monitor other important field bean pests. The tasks of project: Analysis of field bean seed material before sowingTo continue the evaluation of different monitoring methods to determine the population density and flight activity of the broadbean seed beetle during the growing seasonMonitoring of other field bean pestsContinue to evaluate the effectiveness of different limitation periods in field bean crops, for limiting the population of the broadbean seed beetleDetermination of germination of seeds damaged by the broadbean seed beetle Results Field bean harvest data collected in the project in the period from 2017 to 2019 leads to the conclusion of a tendency for the rate of broadbean seed beetle damage to increase. Monitoring methods-imago records on the plant, measurement of water traps and transparent glue shields, are not usable, for the development of the critical threshold of the insect to detect the need for the insecticide application. Assessments on plants are acceptable as an indicator for determining the presence of broadbean seed beetle in the field in general.
