Field Efficacy of Spinetoram for the Management of Coffee Berry Borer (Hypothenemus hampei)

Abstract

Coffee berry borer (CBB), Hypothenemus hampei, is a damaging insect pest of coffee worldwide. CBB has recently been introduced to Hawaii, so management techniques are still being developed for sustainable and cost-efficient approaches for the effective control of this pest. Field trials were conducted to evaluate the use of spinetoram on CBB infestation and bean damage compared to Beauveria bassiana and an untreated control. Initial CBB infestations were similar, and the treatments resulted in no detectable differences in subsequent new infestations. Damage to the coffee beans was reduced by both spinetoram and B. bassiana compared to controls as the mortality of adult beetles resulting from the treatments prevented them from moving into the bean (C/D position) from the berry (A/B position). The mortality of adult beetles also prevented reproduction, subsequently reducing future CBB populations in the field. When applied to infested berries, spinetoram reduced live beetle populations in the A/B position by 73% and CBBs in the C/D position by 70% compared to the water control, whereas applications of B. bassiana reduced beetles in the C/D position by 37% but had no effect on the live A/B population. An integrated pest management program is recommended for the effective control of CBBs, and the use of spinetoram applications when adult beetles are in the A/B position appears to have potential as another management tool.

Establishing an Integrated Pest Management Program for Coffee Berry Borer (Hypothenemus hampei) in Hawaii and Puerto Rico Coffee Agroecosystems: Achievements and Challenges

“…In Hawaii, two strategies for monitoring CBB populations from infested berries have been refined and validated for statistical robustness. The 30-tree sampling plan for monitoring CBB infestation was developed in Colombia [9] and introduced to Hawaii in 2012 by Luis F. Aristizábal [55]. The 30-tree method is a good predictor of CBB populations even at a low rate (≤1%) of infestation [56].…”

“…In Hawaii, strip-picking is recommended as a critical part of the IPM program for CBB control [34,69]. This practice is regularly conducted in the Kona district of Hawaii Island on coffee farms that are at low and middle elevations (200-600 m), where the harvest season is short (3-4 months).…”

“…data). These products are applied alone or in a tank mixture with B. bassiana [69,79,142]. A recent field study testing the efficacy of spinetoram, whose active ingredient is derived from the fermentation of Saccharopolyspora spinosa, a naturally occurring soil organism, reported up to 73% control when CBB were in the AB position [143].…”

Uso de caulim processado como técnica sustentável de mitigação dos efeitos das mudanças climáticas na produção agrícola

“…Observou-se que o caulim processado e purificado é agente repelente contra a presença da Broca do café, cuja taxa de presença se manteve inferior a 2% ao longo do período de frutificação. Associado ao inseticida biológico Mycotrol®ESO, demonstrou efeito de repelência também contra presença de afídeos, tripes e mosca-branca (Kawabata, Nakamoto, Curtiss, 2015;Reis, Souza, Santa-Cecília, Silva, Zacarias, 2010).…”

Coffee berry borer (Coleoptera: Scolytidae) population dynamics across Hawaii Island’s diverse coffee-growing landscape: optimizing location-specific pesticide applications

“…The establishment of coffee berry borer in 2010 drastically changed the way coffee was grown and managed in the islands ( Lee et al 2023 ). In addition to the usual activities needed to maintain the farm, growers today often must monitor regularly for coffee berry borer, apply multiple sprays of the biopesticide Beauveria bassiana , conduct frequent and efficient harvesting, and implement postharvest sanitation to prevent the complete destruction of the crop ( Aristizábal et al 2016 , 2017a , 2023a , Johnson et al 2020 , Kawabata et al 2020 ). The nearly continuous mosaic of coffee (including feral plants, abandoned, unmanaged, and managed farms) across the Kona and Ka’u districts of Hawaii Island allow coffee berry borer population reservoirs to persist year-round, with poorly managed farms often serving as sources of coffee berry borer that reinfest neighboring farms ( Johnson and Manoukis 2020 ).…”
