Butter seed insect, Acanthoscelides obtectus (Say) (Coleoptera: Chrysomelidae), is a species that causes damage to the nuts, butterflies and butterflies, primarily beans. Acanthoscelides obtectus causes serious problems both in the land and in the warehouse due to its ability to give multiple dots. As a result of the nutrition of the damages, the nutritional value of the bakes decreases, in addition to causing grinding, quality and weight loss in the seed, as well as polluting the grain with nutritional waste and output. Acanthoscelides obtectus also significantly decreases the market value of bakes, which have an important place in the internal and external market. Therefore, the fight with A. obtectus should be carried out rigorously in the warehouse and field. In the fight against harmful ones, the cultural measures should be taken first and the certified seed should be used for this purpose, in the damaged fields should be done late in October. The harvest should not be delayed, the remaining plant remains after the harvest should be buried deep or burned. Plant extract in chemical struggle (ecalyptus oil extract and methanol extract from the tree plant, etc.) It should be given priority to use. Treatment should be carried out taking into account the presence of beneficial insects in the fields that are planted.

The bean weevil, Acanthoscelides obtectus (Say (Coleoptera: Chrysomelidae) is pest species which damages especially beans, and chickpea, coriander and cowpea. Acanthoscelides obtectus causes serious problems both in the field and the storage due to its multiple generations. Its causes the decreasing of legumes nutrient value, germination and quality problems and weight loss, addition to making dirty because of its rotting food and feces. It reduces the market value of legumes in the internal and external trades. For these reasons, the manegement of A. obtectus must be carefully carried out in the storage and the field. The control of A. obtectus was primarily regarded to apply the cultural measurement. For this aim, the certified seed and late planting should be applied in the damaged areas because of the pest. The harvesting should not be delayed, and then the lost harvest should be deeply buried or burned. Plant extracts (the extract of eucalyptus oil extract and rosemary tree etc.) should be primarily used as the chemical control. The applications were done for the control of pest as considering the presence of beneficial insects in the leguminous fields.
