“…If this species cannot be used in other regions, it is suggested to evaluate generalist predators such as Cathartus quadricollis (Guérin-Méneville, 1829) and Ahasverus advena Waltl, 1834 (Coleoptera: Silvanidae), which reduced CBB populations under laboratory conditions by up to 69% and 63%, respectively [20]. Liang and collaborators [37] have also reported predation of CBBs by C. quadricollis ranging 12 to 49% in Hawaii, and recently, Follet et al [38] developed a breeding station for increasing this species in a field conservation biology approach to control CBB in Hawaii.…”

The coffee berry borer (CBB), Hypothenemus hampei (Ferrari, 1867) (Coleoptera: Curculionidae: Scolytinae), native to Africa, is a major global insect pest of coffee. It has invaded many coffee production areas around the world that do not have natural enemies. In this study, two African parasitoids, Prorops nasuta Waterston (Hymenoptera: Bethylidae) and Phymastichus coffea Waterston (Hymenoptera: Eulophidae), were mass-reared for field release against H. hampei in Chinchiná, Colombia. More than 1.5 million wasps of each species were released on a 61-hectare coffee farm in replicated plots, resulting in parasitism rates of up to 7.7% for P. nasuta and 56.3% for P. coffea. This led to a maximum reduction in H. hampei field populations of 81% from dispersal coffee plots (old coffee crops before plant stumping) and 64.3% in colonization coffee plots (new coffee crops with active growing and fruiting plants) within the farm. As a result of this area-wide strategy, the percentage of CBB-infested coffee berries in colonization coffee plots decreased from 51.1 to 77.5% compared to coffee plots without parasitoid releases. This approach offers a promising alternative to the use of chemical insecticides and could be integrated into current pest management programs to control H. hampei.

“…To develop successful area-wide IPM programs, it is critical to understand how coffee berry borer populations persist and disperse across the landscape ( Rodríguez et al 2013 ). Field studies conducted in Hawaii over the last 13 years have provided location-specific information on coffee berry borer development ( Hamilton et al 2019 ), flight activity ( Messing 2012 , Aristizábal et al 2017b , Johnson and Manoukis 2021 ), infestation ( Aristizábal et al 2017b , Johnson and Manoukis 2020 ), postharvest reservoirs ( Johnson et al 2019 ), Beauveria bassiana efficacy and spray strategies ( Greco et al 2018 , Hollingsworth et al 2020 , Woodill et al 2021 , Wraight et al 2021 , 2022 ), biological controls ( Brill et al 2021 , Castrillo et al 2020 , Follett et al 2016 , 2023 , Hollingsworth et al 2011 , Kawabata et al 2016 , Sim et al 2016 , Wraight et al 2018 , 2022 , Yousuf et al 2021 ), physical controls ( Johnson et al 2020 ), chemical controls ( Kawabata et al 2023 ), and cultural controls ( Aristizábal et al 2023b ). Still, there remain gaps in our knowledge of coffee berry borer population dynamics over space and time, limiting our understanding of the relative importance of site-specific differences among farming districts and elevations in this small but economically important and world-renowned coffee-growing region.…”

A major challenge to area-wide management of coffee berry borer (Hypothenemus hampei Ferrari) (Coleoptera: Scolytidae) is understanding how a heterogeneous coffee-growing landscape affects coffee berry borer population dynamics across temporal and spatial scales. We examined coffee phenology, weather, coffee berry borer flight activity, infestation, coffee berry borer position within the fruit, and management across 14 commercial coffee farms from 2016 to 2018 on Hawaii Island to characterize variation among districts and elevations. Here we aim to determine whether the timing of pesticide applications might be optimized based on specific locations. We observed larger populations of coffee berry borer at low-elevation farms and in the Kona district compared to mid- and high-elevation farms and the Ka’u district. Temperature, relative humidity, and rainfall all differed significantly across districts and elevations. We also observed a trend of higher fruit production at low-elevation farms compared to high-elevation farms, and differences in the timing of fruit development. Infestation increased with higher pest pressure and air temperatures and reduced fruit availability early and late in the season. Lastly, the timing and number of management interventions varied among districts and elevations. Combining information on trap catch, infestation, coffee berry borer position, and plant phenology, we present an optimized pesticide spray schedule for each location and find that the number of sprays could be reduced by 33–75% in comparison to the existing integrated pest management recommendations while maintaining effective control. Implementing a coordinated area-wide approach refined by small-scale optimization will lead to improved management of coffee berry borer on individual farms and a reduction in pest pressure across the coffee-growing landscape.

The explosion of pests and diseases due to climate change

Climate change has been felt over the last few decades in Indonesia, especially in Aceh. Uncertain climatic conditions can affect crop production and food distribution. Insect pests and plant pathogens respond differently to various causes of climate change. An increase in temperature causes changes in the behavior of pests and diseases in terms of their ability to attack. This review discusses the impact of rising temperatures and CO2 levels in the atmosphere on the ability to attack insect pests and pathogens on crops. Global climate warming is expected to trigger an expansion of pests and disease geographic distribution from lowland to highland, increase their survival, and increase the number of new host plants. The survey carried out in Central Aceh on an Arabica coffee plantation showed that leaf spots caused by Hemiliea vastatrix can attack a coffee plantation at an altitude of 1.400 meters, while the same case is also found at the same altitude where coffee berry borer pest (Hyphothenemus hampei) and coffee leaf miner (Leucoptera coffeella) can attack arabica coffee plantation. A comprehensive assessment of the impact of climate change on pests and plant diseases needs to be carried out to get an integrated pest management strategy.
