There is a private park decorating with poinsettia (the Christmas flower) before Christmas. Later, the rolling leaves were noticed in few pots with powder. At the same time, thrips were found at the mango tree and galls were found on leaves. There was a huge piece of the dead trunk with a great amount of sting bug population. Some whiteflies were found at golden dewdrops around the park but did not seem to harm the plant at the moment. You are required for a maintenance project in the garden. Please write a proposal from the entomological point of view for proximate and ultimate maintenance tasks for the lowest cost and why you think those tasks are necessary.
