Data from the Association of Sea buckthorn Growers in Lithuania shows that approximately 2,500 hectares in the country are currently covered with sea buckthorn. It was previously a common belief that sea buckthorn was the only plant suitable for organic farming, as it was thought to be free from pest attacks. However, this is no longer the case. The sea buckthorn fly (Rhagoletis batava, Hering) has now become widespread in sea buckthorn plantations. Since 2015, studies on the abundance, biology, harmfulness, and control methods of the sea buckthorn fly were conducted in plantations located in the southern and northern Lithuania. The results showed that the activity of the sea buckthorn fly in the southern plantation began during last decade of July, peaked on beginning of August, and the last pests were detected during the end of August and beginning of September. The plant protection product of the biological origin used for sea buckthorn fly pupae control was ineffective.
