Emergence and Infestation Level of Hypothenemus hampei (Coleoptera: Curculionidae) on Coffee Berries on the Plant or on the Ground During the Post-harvest Period in Brazil

Abstract

The coffee berry borer (CBB), Hypothenemus hampei Ferrari (Coleoptera: Curculionidae), is the most important coffee pest in most of the coffee growing countries. CBB females leave old dry berries after harvest and search for dry noninfested berries on the plant or on the ground to lay eggs or to use as refuge until new berries are available on the coffee trees in the following season. The CBB infestation level and emergence from berries on the ground or on the plants were evaluated in two fields post-harvest in the Spring in Brazil over two seasons. Twenty infested or noninfested berries in separate cages (250 ml plastic cups) were placed on the plants or on the ground under the tree canopy, in each field. The number of infested berries and CBB females that emerged from the infested berries were recorded weekly. CBB emergence was higher from berries on the ground than those on the coffee trees in both seasons, whereas CBB infestation was higher on coffee berries on the plants than those on the ground in season I. Insolation (hours of sunlight) and temperature were the main covariates that affected emergence and infestation by this insect. The results are discussed for monitoring CBB during the time of dispersal with implications on integrated management of this pest.

Coffee berry borer population on the arabica coffee beans from three different cropping patterns in Karo, North Sumatera

“…Compared to the polyculture cropping patterns, the monoculture cropping pattern had a significantly higher number of eggs, larvae, and adults during the observation (Figure 6.). Higher infestation in the monoculture cropping pattern might be a result of the closer proximity of the coffee trees, as [15] said female adults of CBB search for uninfested coffee berries and use the berry to lay eggs or as a shelter until fresh coffee berries are available on the coffee plants, so it will be easier for female imago CBB to get uninfested berry around it because the coffee plants grown using a monoculture planting scheme were spaced closer together than those grown using a polyculture planting pattern. It is also supported by the statement of [2], which states that the female CBBs leave their natal berries and are likely to infest the next-closest berry in the trees suited for oviposition.…”

“…The targeted berries are either on the plant or already on the ground. The female CBBs will use these berrieto to lay eggs or become their shelter until new coffee berries are available on the coffee plants [15]. It also affects the CBB infestation in the following harvest period, followed by shade plant factors, population density, plant care, and climate [14].…”

“…Perkembangan hama PBKo terjadi di dalam buah kopi (Escobar-Ramírez et al, 2019). Larva memakan bagian endosperm yang menyebabkan kerugian kuantitatif seperti kehilangan berat biji serta kerugian kualitatif yaitu hilangnya nilai komersil produk karena biji berlubang (Carvalho et al, 2021;Mariño et al, 2021). Imago betina keluar dari buah kopi yang sudah kering dan mencari buah kopi yang belum terserang pada pohon kopi atau di tanah untuk bertelur dan untuk digunakan sebagai tempat berlindung sampai buah baru tersedia di pohon kopi (Pereira et al, 2021).…”
