Integrated pest management of coffee berry borer in Hawaii and Puerto Rico: current status and prospects. Insects. http://dx.doi.org/10.3390/insects8040123. Interpretive Summary: Coffee berry borer is the most devastating insect pest in coffee production throughout the world. Recently detected in Hawaii and Puerto Rico, growers are dealing with reduced coffee quality and increased costs associated with pest management. Due to differences in cultural practices, regulations, and environmental conditions, IPM programs vary among production areas. Control measures used in other coffee growing regions are not always cost effective in Hawaii and Puerto Rico where there are high labor costs and a shortage of farm workers. Here we summarize the findings of local coffee growers, researchers, and extension professionals in developing an IPM program tailored to our specific challenges. Recommendations for CBB monitoring, insecticide sprays, biological control, sanitation, pruning, and other cultural methods are presented.
Technical Abstract: The coffee berry borer (CBB), Hypothenemus hampei, is the most significant insect pest of coffee worldwide. Since CBB was detected in Puerto Rico in 2007 and Hawaii in 2010, coffee growers from these islands are facing increased costs, reduced coffee quality, and increased pest management challenges. Here, we outline the CBB situation, and summarize the findings of growers, researchers, and extension professionals working with CBB in Hawaii. Recommendations for the Integrated Pest Management (IPM) program for CBB in Hawaiian Islands and Puerto Rico include: (1) establish a CBB monitoring program, (2) synchronize applications of insecticides with peak flight activity of CBB especially during the early coffee season, (3) conduct efficient strip-picking as soon as possible after harvest and perform pre-harvest sanitation picks in CBB hotspots if needed, (4) establish protocols to prevent the escape of CBB from processing areas and when transporting berries during harvest, and (5) stump prune by blocks. Progress achieved includes the introduction of the mycoinsecticide Beauveria bassiana to coffee plantations, the coordination of area-wide CBB surveys, the establishment and augmentation of native beetle predators, and an observed reduction of CBB populations and increased coffee quality where IPM programs were established. However, CBB remains a challenge for coffee growers due to regional variability in CBB pressures, high costs, and labor issues, including a lack of training and awareness of CBB management practices among growers.
