The coffee industry loses millions of dollars annually worldwide due to the Coffee Berry Borer (CBB); these losses imply a decrease in quality and production. Traps are used to monitor their flight and for pest control. The main objective was to determine the flight pattern and trap capture percentages of the CBB population over time using column traps (CTs) in two independent field experiments. CTs were composed of four traps installed at four different heights 0.5, 1.5, 2.5, and 3.5m above ground. Our results demonstrated a significant difference in CBB capture by traps placed at different heights above the ground. The CT capture maintained a pattern throughout this study's lag; the lower the height, the greater the percentage of CBBs captured. In Experiments A and B, the traps placed at 0.5m caught 67% and 85% of the CBBs captured, respectively. Furthermore, the trap set at 1.5m above the ground in the multi-level CT showed a higher capture percentage than the individually placed trap (also at 1.5m). The pattern of the capture and proportion of the CBB in the CTs were maintained throughout the study despite the season, changes in temperature, and relative air humidity. We suggested that CTs could be explored as a useful tool for capturing the CBB, considering its monitoring and management.

Traps lured with semiochemical have been proposed to manage the coffee berry borer, coffee planting is however made under several environmental conditions that may affect the efficacy of traps. Several trap designs and variations were proposed and, therefore, a series of field experiments was carried out to capture coffee berry bores in traps disposed in a low density coffee plantations in the Northern part of the State of Paraná, Brazil. Traps were composed of plastic bottles (2 L) with a window (13 × 18 cm). Ethanol (E), Methanol (M) and coffee oil alone did not improve the capture when transparent traps with a 2 mm hole in the vial dispenser were used; traps lured with E : M mixtures (1:1, 1:2, 1:3) caught similar and higher number of insects than the control. There was synergism with the mixing of E and M; the addition of coffee oil to the mixtures did not improve the capture. Trap lured with E : M (1:1) mixtures at 342, 400, 428 and 710 mg caught similar numbers of insects. Transparent green trap, transparent trap and red trap lured with 642 mg day-1 of the E + M (1:1) mixture caught similar numbers of insects. Interaction between colors (transparent green, transparent and red) and semiochemical release rates (540, 720 and 1100 mg day-1) was observed. Transparent green trap, when lured with 720 mg day-1 of the 1 : 1 E : M mixture caught 2.3 and 4.4 times more insects than 540 and 1100 mg day-1; and caught 3.2 times more insects than transparent and red trap at the same release rates.

Exclusion nets are increasingly being used to protect a variety of agricultural crops from insect pests as a sustainable alternative to chemical controls. We examined the efficacy of exclusion nets in controlling the world’s most damaging insect pest of coffee, Hypothenemus hampei (coffee berry borer), on two small-scale coffee farms on Hawai’i Island. We recorded microclimate data, fruit infestation, population per fruit, sex ratio, mortality by Beauveria bassiana, coffee yield and quality in four paired exclusion and control (un-netted) plots on both farms. Mean and maximum daily temperature and relative humidity were similar between treatments, while mean and maximum daily solar radiation was reduced by ~50% in exclusion plots. Green and ripe fruit from exclusion plots had significantly lower infestation compared to un-netted control plots at both farms. We observed no significant difference between exclusion and control plots in the number of CBB per fruit or the female:male sex ratio. CBB mortality was significantly higher in control relative to exclusion plots in one of the two farms. Ripe fruits harvested from exclusion plots were on average significantly heavier and wider than those from control plots; however, there was no significant difference in the average yield per tree between treatments. Lastly, coffee quality was not significantly different between control and exclusion plots. Our results suggest that with complete sanitation prior to net installation in an environment where CBB is actively circulating, exclusion netting can successfully control CBB on small-scale coffee farms without reducing coffee yield or quality, and has the potential to lower production and labor costs by eliminating the need to spray pesticides.

A technique for dissecting the alimentary canal of the coffee berry borer, <em>Hypothenemus hampei</em>, is presented. The technique was developed to isolate and identify alimentary canal-associated microorganisms that might be involved in caffeine detoxification.

A trial on cyantraniliprole 10% against coffee berry borer (Hypothenemus hampei) has been conducted on arabica coffee at Kalibendo Estate, in Banyuwangi regency, East Java. The altitude of the estate is about 650 m above sea level (asl.) and belongs to B type of climate classification according to Schmidt and Ferguson. Composite variety of arabica coffee at about four years old planted at the location was used as plant materials. Five levels of cyantranilprole dosage and two compared insecticides i.e: carbaryl 85% and lamda cyhalothrine 25 g/L have been applied as treatments and each treatment is replicated four times. Infestation of coffee berry borer (CBB) has been observed on berries in the field as well as on harvested berries and green coffee. The results revealed that cyantraniliprole 10% was very effective in suppressing infestation and population of CBB on coffee berries in the field as well as on harvested parchment and green coffee. The dosage of 2,000 ml/ha was the most effective and the highest level of efficacy against CBB until the last observation during 14 weeks trial. Application of cyantraniliprole 10% also has increased the production of green coffee harvested. The highest increase occurred on the treatment of cyantraniliprole 10% with a dosage of 1000 ml/ha, which it reached 62.87% higher compared to untreated treatment. Carbaryl and lamda cyhalothrine have effectiveness and efficacy level lower than the highest dosage of cyantraniliprole 10%.
