insects are responsible for destroying all types of indoor & outdoor plants. Spider mite, mealybug, aphid, whitefly and scale insect are major culprits. They infect various indoor plants, outdoor plants, fiber crops, ornamental and forest crops. insects plant sap and cause chlorosis, which adversely affects photosynthesis. These insects are most difficult to control because of their high reproduction potential, ability to coexist in overlapping generations, high adaptation potential, and worldwide distribution. Some of them protect themselves under white powdery coating, which keeps them protected from insecticides and natural enemies.
