Photos of How Hypothenemus hampei Destructs Coffee Bean
Coffee Berry Borer (CBB) is now the most destructive pest to coffee fruits worldwide and North Sumatera of Indonesia.  The data can be found in page Coffee Berry Borer Hypothenemus hampei.  The impact can be read on the page Coffee is Now on the Way to Death.  

       CBB or Broca get scientific name Hypothenemus hampei.  CBB get named Penggerek Buah Kopi (PBKo) in Indonesian.  CBB is small beetle.  The adults is  small black beetles. Females  are 1.4–1.8 mm long. The males are smaller, 1.2–1.6 mm long. Female beetles can fly short distances; males have no wing. CBB life cycle is 24-45 days, depends on climate. 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).

       In Ecoscofas principles, CBB must be controlled through Good Agriculture Practice in Coffee Field.  Otherwise, the future of coffee production is questionable and unclear.
Thank you for your visiting and attention.

AMARTA II Coffee Stakeholders Meeting

AMARTA II Coffee Stakeholders Meeting (Pertemuan Pemangku Kepentingan Kopi AMARTA II)
The world's need on coffee increases significantly. For it, the production and quality of coffee must be increased significantly by creating a better coffee value chain starting from producers to drinkers as the end-users. There were some success that had been achieved in Indonesia especially in North Sumatra Province, but there are still much more to do in the future for the sake of sustainability of supply and quality. The action programs will be formulated in the next step by ACDIVOCA, the winner of tender of AMARTA II Project. Farther meetings are needed to hear what activities will be offered by ACDIVOCA. We all are keen to know. Let's wait the invitation letters from ACDIVOCA. 

Those mentioned above were some general conclusions that I could draw from the  AMARTA II Coffee Stakeholders Meeting held by USAID-AMARTA II Project in Grand Aston Hotel Medan on Monday 13 February 2012.
