As the pest spreads, the tomatoes weaken, the development of the bushes slows down. The leaves turn yellow and dry, and the stems curl up. The pest releases a poison that can destroy the plant. The females lay their eggs on the underside of the leaves, so the seedlings need to be inspected carefully.
