Although coffee beetles have not been seen in coffee gardens in Taiwan, in recent years some people have imported unfinished coffee fruits from abroad for seedling use. If fruit with insects is introduced, these insects will spread everywhere, and I am afraid that this pest will appear in Taiwan in a few years. When planting coffee, you have to be careful not to buy coffee seedlings from unknown sources, especially not to buy seedlings cultivated from imported seeds. Buying coffee seedlings from these seeders is equivalent to helping them introduce coffee fruit beetles. Planting that seedling and introducing the coffee berry beetle into your own coffee garden would destroy your investment before it kills anyone. Avoid importing coffee beans from Africa that are not completely dried. Moreover, the characteristics of the existing varieties of Taiwanese coffee are expressed in quality, and it is very likely that the quality is better than that of African disease.

The microbial damage is very serious in coffee producing areas all over the world. Disease control is a very important work in coffee plantation management. Without disease control, yield and quality will be affected. The main diseases in Taiwan are Leaf Rust (LR), Coffee Berry Disease (CBD) and Brown Leaf Disease. Disease occurrence varies according to altitude. Basically, the mountain temperature is cooler, the cloud is more, the coffee leaf rust damage is very serious, the coffee anthracnose damage is relatively mild; the flat temperature is high, the coffee anthracnose damage is quite common, the damage situation is very serious. And affect the quality of coffee beans, not only make coffee beans become defective beans, brewed coffee taste turbid and with a bad smell.

Hypothenemus hampei (Ferrari), English name Coffee berry borer, abbreviated CBB, belongs to Coleoptera, Scolytidae insects. This insect is currently the most serious pest in coffee producing areas in the world, widely distributed in more than 70 coffee-producing countries, mainly damaging fruits on trees and green beans after harvest. This paper describes the ecology and control methods of this insect for reference by coffee farmers.
