Although there is no sign of coffee fruit beetles in coffee gardens in Taiwan, some people will import undried coffee fruits from abroad in recent years for breeding purposes. If fruit with insects is introduced, these insects will spread everywhere, and I am afraid that this kind of pest will appear in Taiwan in a few years' time. When growing coffee, you have to be careful not to buy coffee seedlings from unknown sources, especially those cultivated by imported seeds. Buying coffee seedlings from these seedling dealers is tantamount to helping them introduce coffee fruit beetles. Planting that kind of seedlings and introducing coffee fruit beetles into your own coffee garden will cost you all your investment before you hurt anyone. Don't avoid importing coffee beans that are not completely dry from Africa. In addition, the quality of the existing coffee varieties in Taiwan is likely to be better than that in African disease areas.

In all coffee producing areas in the world, the damage caused by microorganisms is very serious, and disease control is a very important work in coffee garden management. If the disease is not well controlled, the yield and quality will be affected. The main diseases in Taiwan are coffee leaf rust (Leaf Rust, LR), coffee anthracnose (Coffee Berry Disease, CBD), brown leaf disease. The occurrence of the disease varies according to the altitude. Basically, the temperature in the mountain area is relatively cool and cloudy, the damage of coffee leaf rust is very serious, and the damage of coffee anthracnose is relatively mild; with high flat temperature, coffee anthracnose is quite common, and the damage is very serious. And the shadow to the quality of coffee beans, not only make coffee beans into defective beans, brewing out of the coffee taste muddy and with a bad smell.

Coffee bark beetle Hypothenemus hampei (Ferrari), whose English name is Coffee berry borer or CBB for short, belongs to Coleoptera and Scolytidae. This insect is currently the most serious pest in coffee producing areas in the world. It is widely distributed in more than 70 coffee-producing countries. It mainly harms fruits on trees and raw beans after harvest. In this paper, the ecology and control methods of this insect are described in detail, which can be used as a reference for coffee farmers.
