Prevention and control

Fenthion, fenitrothion, deltamethrin, esfenvalerate, lambda-cyhalothrin and chlorpyrifos-methyl + cypermethrin have all been used to control A. orbitalis (Bouyjou et al., 1999).


Economic losses can occur as follows:

Losses due to the shedding of the young fruits. These losses are difficult to quantify.

Losses due to the occurrence of the fungus Nematospora spp. (Endomycetales) in the fruit following Antestiopsis wounding.

Losses due to infested beans which are the most significant. The percentage of infested beans is very variable, from 10 to 32% or more without treatment.

Moreover, in the great lakes area of East Africa, arabica coffee can develop an undesirable taste known as 'peasy', 'goût de pomme de terre (GPDT)' or 'erbsig'. This reduces the quality of the commercial coffee. The taste is due to a bacterium belonging to the family of Enterobacteriaceae which has not yet been fully identified. Studies carried out in Burundi by Bouyjou et al. (1999) showed a link between the number of beans affected by the bug and the percentage of cups with the 'peasy taste'. This work showed that protection against A. orbitalis made it possible to obtain a significant reduction in infested beans as well as a lower rate of tainted cups.
