Nematodes As Biological Control Agents of the Coffee Berry Borer in Mexico
Sustainable Perennial Crops
2012 Annual Report
1a.Objectives (from AD-416):
The project is aimed at identifying nematode species attacking the coffee berry borer in coffee plantations. The objective is to determine whether nematodes are important mortality factors in the field, and whether they can be used as biological control agents to reduce yield losses caused by the coffee berry borer.
1b.Approach (from AD-416):
ARS and Cooperator will gain new knowledge on previously unreported nematodes attacking the coffee berry borer. This information will be used by both parties to jointly determine if the discovered biological control agents can be used as tools against the coffee berry borer. The Cooperator will develop large-scale sampling protocols for assessing the presence of nematodes attacking the coffee berry borer.
The project is aimed at identifying nematode species attacking the coffee berry borer in coffee plantations of Mexico. Coffee berry borer-infested berries from 20 coffee plantations with different climatic conditions have been collected in the Soconusco Region of Chiapas. At each plantation approximately 500 infested coffee fruits that were taken to the laboratory and dissected to assess for the presence of nematodes. More than 5,350 adult coffee berry borers have been dissected and of these, 17 specimens were infected with nematodes. Specimens will be mounted and sent to a collaborator for identification.
