Lecture Description
Insect pests cause great losses in coffee production and yield when they are not properly controlled. The borer is the main pest whose effect is increasing due to climate variability. This change in climate has also caused the proliferation of other pests such as the Indian cricket and the borer with an important economic impact. Honduran Coffee has defined sustainable production with the least possible use of chemical products as a policy, which is why IHCAFE has developed integrated management of these three pests without the use of synthetic insecticides. Management consists of three practices: a) cultural, which consists of eliminating host material, eliminating sources of food and shelter; b) production and use of parasitoids. Follow-up studies on farms show predation of 38.4% and parasitism of 11.7% of biological states of borer in fruits visited by Cephalonomia stephanoderis, parasitism of 5 to 25% of adults of H. hampei by Phymastichus coffea, natural parasitism of 76 is also recorded. % by Acmopolynema sp on Paroecanthus sp eggs, showing the reduction of damage caused by these pests; c) Traps, which contain attractant liquid, this strategy is highly effective, reducing up to 40% of damage.
