Two days after entering the fruits, one female puts 35-50 eggs which consist of 33-46 female. Female CBB’s life is maximum 190 days, and male 40 days. After mating inside the fruits, some of female remain in the fruits, and others go out to infect other fruits. Generally speaking, one CBB female can have hundred of thousands descendant in one year. How dangerous CBB are !! To eradicate it, don't use chemical industries.
The question is : how CBB can destruct coffee bean?
The following photos are the explanation of how CBB destruct coffee bean. Photo 1 shows the healthy fruit. CBB bores coffee fruits, lives then inside, and eats the coffee bean inside (Photo 2, 3). In the end, all coffee beans are eaten by CBB, and therefore no more beans available in the fruit (Photo 4). Infection of CBB on very young fruits causes rottening (Photo 5), and then fruits fall (Photo 6).

Photo 2. CBB bores coffee fruit, then lives inside (Sabam Malau, 2010)
Photo 4. CBB eats coffee bean inside fruits, and no coffee bean can then be harvested (Sabam Malau, 2010)
Photo 5. Infection of CBB on very young fruits causes rottening (Sabam Malau, 2010)
In Ecoscofas principles, CBB must be controlled through Good Agriculture Practice in Coffee Field. Otherwise, the future of coffee production is questionable and unclear.
