Abstract

The economic crisis also hit hard the agricultural sector, as production inputs such as synthetic chemical pesticides and fertilizers became expensive and at times hard to get. But the ingenious and innovative thinking of the farmers were sometimes proven invaluable. They look back at the practices inherited from their ancestors: using plant materials as botanical pesticides as well as compost. While earlier the farmers were told that botanicals' use promotes safer environment and cleaner products, later they chose the alternative with more economical consideration. Unfortunately they have little, if available, records and notes regarding these promising plant materials. Not much have been done in the past to identify and record the kinds of plant and plant materials with pesticidal properties. This study was done based on this premise. Rembang regency in north-eastern Central Java is a region with diverse area, starting from low coastal land to woody tropical hills. The farmers living in the area has long known the use of botanicals, but not as intensive as during the present (the year 1998–2000). The systematic and thorough inventory and identification of such botanicals, however, has yet to be done. Therefore a survey was conducted in Kecamatan Pamotan, Rembang regency, by attending the village gathering, talking to elders and leaders, and through snowball effect method collecting information from farmers who use botanicals to protect their crops. Visit to the field and woods to identify the plants were also carried out. The result is records on the kinds, relative number, the use and other important facts which may serve as the basis for further improvement of these environmentally friendly practices.

Abstract

Recent reviews on Dorsalis and Dacine fruit flies had implication on host-insect inventory, including in Indonesia. Update is needed because of these changes and due to the rising of fruit and vegetable trade within islands, as well as with neighboring countries. Fruits were collected over a 3-year period from 24 provinces of Indonesia, covering areas from Aceh to Papua. This work was done specifically to obtain detailed information regarding the host range of the important species of Bactrocera spp., Atherigona orientalis, and Dacus longicornis, as well as Adrama determinata. Male lure Steiner traps to attract fruit flies were used in this study as an additional method to support species variation.Atotal of 1125 fruit samples were collected from many locations. Thirty five plant species from 18 families were recorded as fruit fly hosts and 27 plant species were new report as specific host for certain species of fruit fly. A larger array of host plants for fruit flies in Indonesia than reported before suggests the importance of effective quarantine measures to limit the spread of harmful fruit fly and to prevent the accidental introduction of invasive alien fruit fly species from other countries.

Abstract

Heptachlor (C10H5Cl7) was an organochlorine insecticide compound, which was considered POPs (Persistent Organic Pollutants) that is highly toxic to human. Since 2007 heptachlor insecticide was banned in Indonesia because of its chronic toxicity, persistency, bioaccumulative, and carcinogenic natures. But its illegal use is still rampant because its dark market availability, cheap price, and is effective in eradicating the pest. Furthermore, there is also lack of assertiveness of regulations and applicable laws. The objectives of the research were to identify pollution, pollution level, spatial distribution, and its correlation with soil chemicals properties, as well as the risks to health caused by heptachlor use. Research was conducted in 2010 by a survey on agricultural land in the regency of Bantul, Province of Yogyakarta Special Region on a 144 point grids. The tool used to determine heptachlor residue was GC-MS chromatography using Shimadzu GC-2014. The analysis showed that heptachlor was detected in soil, water and in agricultural products. Heptachlor residues were detected in 137 locations (95%) of 144 agricultural land sites, and the water residues on 11 sites exceeded the levels set according to levels of Government Regulation No. 82 of 2001. Heptachlor residue levels in agricultural products (rice, corn, soybeans, green beans, peanuts, and shallot) exceeded the maximum residue limit (MRL) established by the ISO (7313:2008). Soil acidity (pH) has very significant effect on the process of dissipation (loss) of heptachlor (p <0.01) in the soil. Based on the rules of Cambardella distribution, it was discovered that heptachlor had spatial autocorrelation with nugget-sill ratio of 35.7%. Heptachlor polluted rice in 37 locations with hazard index values >1.

Abstract

Acetylation of 4-(4-hydroxy-penyl)-3-butene-2-one by anhydride of acetic acid catalyzed by sulphuric acid results in 4-(4-acetoxy-phenyl)-3-butene-2-one compound, and 4-(4-hydroxy-phenyl)-2-butanone compound as a by product. The first compound alone doesn’t attract fruit flies, but a mixture of the two products attracts male fruit flies. This mixture was tested for its attractancy to the fruit flies in Bantul, Sleman and Kulon Progo regencies, Yogyakarta Special Province; along with Cue and Methyl eugenol lures as comparison. The result showed that the mixture was able to attract four fruit flies species, i.e. Bactrocera albistrigata, B. caudata, B. cibodase, and Bactrocera sp1. One genus found has not been able to be identified to species level. Based on its wing morphometric measures, this species is put under Bactrocera dorsalis complex group.

Abstract

The objective of this research was to know the resistance level of beet armyworm Spodoptera exigua to methoxyfenozide. The lara were collected from the shallot production areas in the districts of Nganjuk (East Java), Bantul and Kulonprogo (Yogyakarta Specia Territory) and Brebes (Central JAva). The bioassay used first instars of S. exigua with artificial diets that had been dipped in a series of methoxyfenozide solutions. Larval mortality was recorded at 72 hours after the exposure. The LC50 value of methoxyfenozide for the population from Sanden (Bantul) was the lowest (0.53 ppm) among 16 tested population, therefore it was used as refenrence population to determine the resistance ratio (RR) values of other populations. The RR values of the tested populations varied from 1 to 240,8 times. Population collected from Wanasari (Brebes) was found to have the highest level of resistance of methoxyfenozide as a result of using methoxyfenozide intensively to S. exigua controlling.

Abstract

Response of Diaphorina citri Kuwayama (Hemiptera: Psyllidae) on citrus leaves treated with horticultural and agricultural mineral oil (HMO & AMO) was evaluated under laboratory condition in choice and non-choice trials. Combination of HMO and AMO at concentration of 0 up to 2% was applied to citrus leaves. Mineral oil applications significantly reduced the proportion of D. citri stayed on citrus leaves for feeding with the proposed mechanisms: 1) oils covered leaves thus hampered it for releasing volatile compounds, 2) oil film preventing the direct contact of tarsus or palpus to leaf surfaces, and 3) the volatile compounds produced by mineral oils also blended with plant volatiles in the atmosphere and reduced the probability of olfactory receptors capturing the olfactory cues for locating the feeding site. Mineral oils also increased the mortality of D. citri due to the refusion for feeding on the treated citrus leaves. The effect of AMO was more prominent than HMO.

Abstract

The research was carried out to identify the residue of diazinon in shallot crop which was grown inYogyakarta Special Territory, Bantul Regency (Parangtritis, Samas and Sanden). Questionnaires were also distributed to farmers in the area to find out the background of diazinon application. Samples were taken from these locations and Bantul market, and were analyzed using Thin Layer and Gas Chromatography (TLC and GC) methods. TLC technique detected diazinon residues in all samples except Parangtritis sample from farmers plot with no diazinon spraying. GC results showed that all the samples diazinon residues were well below maximum residue limit (MRL). The least residue level (0.0029 ppm) was detected in one week after harvesting sample from Sanden. The highest residue level (0.0231 ppm) was detected in the harvesting time sample from Parangtritis.

Abstract

There were ten processed wastes (molase, vinase, sludge, ciu, brem, tofu, milk, cacao, fish, and beer) used in these experiments. The experiments were conducted in two separated arrangements: no choice test and choice test. The no choice test was carried by testing the attractiveness of B. carambolae on each waste was compared with water. Each run consisted of four replication, for each replication consisted of 20 females and 20 males. The choice test was conducted by placing all wastes in a cage at the same time. Each run consisted of 15 replication, for each replication consisted of 100 females dan 100 males. The no choice test results showed that B. carambolae tend to visit waste more than water. The choice test results showed that B. carambolae tend to be more frequent visits to beer and cocoa waste. The content of protein inside the waste seemed to play role in attracting B. carambolae to come with.
