Broca (Coffee Berry Borer)

jimseven

I’ve known about Broca (coffee berry borers) for a little while but in truth didn’t know that much about them.

Broca attacking the coffee

For the coffee plant they are insect evil. If they ruin coffee by laying their young inside the fruit who then devour the bean. Not so good for a crop. Elliott’s article is a worthwhile read and I don’t have enough material here with me to write much more than this.

Quite mature Broca

At the ICAFE research labs they are breeding Broca under controlled conditions to better understand them and ultimately their prevention in parts of Costa Rica that may be affected. We had a look at the insides of a bean where they broca are only 18 days old through a microscope and I rather hopefully stuck my camera to the eyepiece. The video is not overly pleasant viewing but I think it is quite interesting. (Give it a chance to load)
