Coffee berry borer [CBB, Hypothenemus hampei (Ferr.)] is the main pest on coffee causing a significant losses. Distribution pattern of the pest is not known deeply until now, especially in Indonesia. The data of distribution pattern of pest is very important in constructing the strategy of integrated pest management, especially to determine a sampling method for monitoring of the pest. This experiment aimed to reveal the distribution pattern of CBB both spatially and vertically. The experiment was conducted on Arabica and Robusta coffee, located in Kalibendo estate in Banyuwangi East Java. A plot with 400 (20 x 20) of coffee trees were observed for infestation and population of CBB, at four branches on south, north, east and west directions for each tree. Collected data were analyzed to obtain the value of mean, variance (=s2), variance/mean relationship (=I), index of Morisita (=Iδ), coefficient of Green (=Cx) and k exponent of Negative Binomial. Results of the experiment revealed that spatial distribution pattern of CBB, both on Arabica an Robusta coffee, as well as for infestation and population parameters, was fit with aggregated or clumped distribution. For vertical distribution, it inclined that CBB infestation and population in the lower part of coffee tree was higher than in central and upper part of coffee tree. Plenty of infested coffee berries leaved on soil surface may result in higher infestation and population in the lower part.Key words: Arabica coffee, Robusta coffee, Hypothenemus hampei, spatial distribution, vertical distribution.

One of the major constraints to coffee production throughout the world is the damage caused by the Coffee Berry Borer (CBB), Hypothenemus hampei (Ferrari). The first report of the occurrence of CBB appears to be that of 1935 in Rathnapura District in Sri Lanka. It is now prevalent in all areas, at varying degree of damage to both Arabica and Robusta coffee. Damage on coffee berries bribes in heavy losses on economical production of coffee in developing countries, including Sri Lanka. The objective of this study was to identify the infestation level of CBB in six selected coffee cultivars and to assess the CBB populations in coffee fields. Six selected coffee cultivars were, Catimour, S4711, HDT of Arabica species and IMY, CCI, BS5 of Robusta species. The experiment was laid out in randomized complete block design, with six treatments and three blocks. Damage severity was recorded on fifty-four tagged coffee plants. Ten branches were selected from a coffee plant where each branch contained more than fifty berries. Data were collected on the same berry cluster, during three months at weekly intervals. Starting from zero damaged berries, the diameter of coffee berry was measured by using a Vernier calliper (0.1mm). Ninety coffee berries were randomly selected from each of Arabica and Robusta for measurements. The data were recorded continuously during the three months at weekly intervals. The results showed that there were significant CBB damage differences among the coffee cultivars. Among the selected cultivars BS5 was the least damage by CBB and HDT was the most susceptible cultivar and S4711 was also found to be susceptible but to a lesser extent. CBB populations were high in Arabica field than in Robusta field. When the diameter of the coffee berry increase, the level of infestation of CBB also increases.

AbstractSeven presumed Mendelian enzyme loci (Est-2, Est-3, Gpi, Idh-l, Idh-2, Mdh-2 and Mpi) were characterized and tested for polymorphism in coffee berry borers, Hypothenemus hampei (Ferrari), sampled in Côte d′Ivoire, Mexico and New Caledonia. The average genetic diversity was H = 0.080. Two loci, Mdh-2 and Mpi were polymorphic, and thus usable as genetic markers. The population structure of H. hampei was analysed using Weir & Cockerham's estimators of Wright's F-statistics. A high degree of inbreeding (f = 0.298) characterized the elementary geographic sampling unit, the coffee field. The estimate of gene flow between fields within a country was Nm = 10.6 and that between countries was Nm = 2. The population genetic structure in H. hampei could be related to its known population biological features and history.

Coffee agroforestry systems could reconcile agricultural and environmental objectives. While pests and diseases can reduce yield, their interactions with shade and nutrition have been rarely researched, and are particularly lacking in perennial systems. We hypothesized that intermediate shade levels could reduce coffee pests while excess shade could favor fungal diseases. We hypothesized that organic rather than mineral fertilization would better synchronize with nutrient uptake and higher nutrient inputs would be associated with reduced pest and disease damage due to higher plant vigor, yet effects would be less obvious in shaded plots as coffee growth would be light-limited. Using three-year-old trees of Coffea canephora var. Robusta (robusta coffee) in the Ecuadorian Amazon, we compared a full-sun system with four shading methods creating different shade levels: (1) Myroxylon balsamum; (2) Inga edulis; (3) Erythrina spp.; or, (4) Erythrina spp. plus Myroxylon balsamum. Conventional farming at either (1) moderate or (2) intensified input and organic farming at (3) low or (4) intensified input were compared in a split-plot design with shade as the main plot factor and farming practice as the sub-plot factor. The infestation of the following pests and disease incidences were evaluated monthly during the dry season: brown twig beetle (Xylosandrus morigerus), coffee leaf miner (Leucoptera coffeella), coffee berry borer (Hypothenemus hampei), anthracnose disease (Colletotrichum spp.), thread blight (Pellicularia koleroga), and cercospora leaf spot (Cercospora coffeicola). Coffee berry borer and brown twig beetle infestation were both reduced by 7% in intensified organic treatments compared to intensified conventional treatments. Colonization of coffee berry borer holes in coffee berries by the entomopathogenic fungus Beauveria bassiana was also assessed. Brown twig beetle infestation was significantly higher under full sun than under Inga edulis, yet no other shade effects were detected. We demonstrate for the first time how intensified input use might promote pest populations and thus ultimately lead to robusta coffee yield losses.

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%.
