Abstract

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.

Abstract

Studies on the field trapping of coffee berry borer (CBB, Hypothenemus hampei) have been conducted to evaluate trap color, trap design and lures (attractant substances). The trials were conducted in a Robusta coffee plantation in East Java during August to December 2004. The trap color evaluated were red, orange, yellow, green and blue, set up in the coffee plantation using a four funnels trap. The traps installed on wood poles at a height of 175 cm above ground and placed among coffee trees. Observations were conducted every day for a week. Result of the study showed that the red and blue color traps captured CBB significantly higher than the others. During a week, the red color captured 1694 CBB adults while the blue one captured 1619 CBB adults. Peak number of captured CBB of the red and blue trapping occurred on the third day with the number of CBB of 416 and 395, respectively. In the evaluation of trapping design, four types of trapping were tried at the same location. The types of trapping were single funnel red trapping, four funnel red trapping, bottle trap with two straight opposite holes, and bottle trapping with two-zigzag holes. Bottle trapping was made of plastic bottle of 1.5-litre capacity, provided with two holes at its opposite wall. Setting up of the trapping in the field and the observation time were in the same way with the trial in trapping color evaluation. Results obtained indicated that the bottle trapping with two straight opposite holes captured the highest number of CBB followed by four funnel red trapping i.e. 547 and 69 per week, respectively. The peak number of trapped CBB occurred at the third day, as at the color trials. Furthermore, four lures have been evaluated int order to obtain the most effective substances for CBB trapping. Substances of A, B, C and D were set up in a coffee plantation using two types of trapping, four funnel red trapping and bottle trapping with two straight opposite holes. The results showed that the substances of B, C and D captured higher CBB adult than A. Nevertheless, this results was not fully convincing since the number of CBB trapped was low, which was due to low population of the CBB during the last trial.

Abstract

Coffee pests known as coffe berry borer (CBB, Hypothenemus hampei) were main pests which decreasing the productivity of Indonesian coffee. One of pests controlling was done by insecticides. Generally, plant uses for insecticide show high security level, because the breaking molecule was easy as not dangerous compound. Pangium edule contains of flavanoide, cyanide acid and saponin had potential as an botanical insecticide. The purpose of this research was to prove the potential extract of seed and leaves of picung (Pangium edule) as an botanical insecticide for CBB. This research used a complete random design. There were 8 treatments with the concentration of the extract from leaves and seed of picung, one positive control treatment (Carbaril 0,02% formulation) and one negative control treatment (aquades). The treatment was repeated four times and carried out observation on every day until six days. The concentrations leaf and seed extracts were 1.0%, 2.5% and 5.0%. The result of the research show that between concentration applied the were no significant different and at observation six days after application the mortality of CBB only around 35 -40% on both extracts (ewater and methanol). The result of the research also show that there were no real differentiation between leaves and seed of picung. LT-50 values were 1.25% and 0.96%, for leaves and seed extract in water for six day observation. From this observation could be concluded that picung tree (Pangium edule) is not effective in the controlling CBB in the interval concentration applied and extraction method used. Key words: Botanical pesticide, picung tree, Pangium edule, mortality, Hypothenemus hampei, water extraction, methanol extraction.

Abstract

AbstractPratylenchus coffeae is a parasitic nematoda that infected the roots of some plants, one of them is coffee. The Infection of Pratylenchus coffeae cause root tissue damage that led to root lession and make root become rotten, it will interfere the ability of roots to absorb water and nutrients in the soil which resulted in the growth of plants. At the moment, control of Pratylenchus coffeae are following integrated pests management (IPM) program, which integrated between the use of coffee resistant clone and application of biological agents. Research on biological control was conducted more intensive, at the moment; due to it is friendlier save against environment and cheaper then using chemical nematicides. The research was conducted to know the effects of Micorrhiza Helper Bacteria (MHB),Pseudomonas diminuta and Bacillus subtilis in suppressing the population of P. coffeaeas well as their effect on growth of coffee seedling.  Coffee arabica (Coffea arabica L.) seedling one moth old were used in the experiment. The experiment prepared with eight treatments and five  replications, as follows: A (Pseudomonas diminuta with density of 108 cfu / ml), B (Pseudomonas diminuta with density of 2x108 cfu / ml), C (Bacillus subtilis with density of 108 cfu / ml ), D (Bacillus subtilis with density 2x108 cfu / ml), E (Carbofuran nematicide 5 g formulation / pot), F (Pseudomonas diminuta and Bacillus subtilis with each density of 108 cfu / ml), K- (Nematoda inoculation but without bacteria and nematicide), K+ (coffee seedling  without any additional treatment). The experiment was conducted for sixteen weeks or about four months. The results of the experiment showed that application of MHB could suppress population of P. coffeae and increase coffee seedling growth significantly. Inoculation of B. subtilis at 108 cfu per seedling suppressed significantly nematoda population of 71.3% compared with untreated seedling but inoculated with nematoda. It was not significant different with carbofuran treatment which could suppress nematoda population by 89.7%. The same result also occur on the treatment of P. diminuta at density level 2.108 cfu/seedling, which could suppress nematoda population by 64.2%. Seedling growth were treated with MHB also significantly increase compared with seedling without treatment and inoculation of nematodas, especially on the treatment of B.subtilis at density level 108 cfu and P.diminuta at density level of 108 cfu, with increasing level of 35.4% and 34.2 %, respectively.Keywords: MHB (Mycorrhiza Helper Bacteria), Arabica coffee (Coffea arabica L.),  Pratylenchus coffeae, Bacillus subtilis, Pseudomonas diminuta.

Abstract

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%.

Abstract

Shade plants affect the microclimates around the plants which directly affect the population of arthropods, especially insects. Therefore, this research was needed to analyze the diversity and role composition of insects in Robusta coffee plantations based on different intensity of shade plants. Samplings of insects and parasitic nematodes were conducted in intercropping patterns of Robusta coffee namely mixed intercropping patterns, coffee-pepper intercropping patterns and coffee-banana intercropping patterns. In each intercropping pattern of Robusta coffee, samplings were conducted as much as ten plants using random sampling. Data analysis was done by calculating the Shannon-Wiener diversity index (H') and evenness index (E). The results showed that diversity index in all Robusta coffee intercropping patterns were < 3, indicating that the diversity of insects in all intercropping patterns was relatively. Insect diversity in coffee-pepper inter- cropping pattern is found higher than the one in either mixed intercropping pattern or coffee-banana intercropping patterns. Out of those intercropping patterns, insects from Formicidae family of Hymenoptera order was found to be the most dominant insects. The composition of insects in all of those three intercropping patterns has been mainly dominated by insects from the family of Formicidae and Hymenoptera order since they are natural enemy insects. Pratylenchus coffeaehas been confirmed as the most dominant nematode species in the three Robusta coffee intercropping pattern. P. coffeae had the highest population average of 3279 in coffee-pepper intercropping pattern.
