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

Khapra beetle, Trogoderma granarium Evert (Celeoptera: Dermestidae) entered Central Java together with importation of stored products four decades ago. A survey was conducted to detect whether the Kaphra beetle existed in Central Java after they had been fumigated during commodity arrival. If the Kaphra beetle is absent, the data could be treated as the starting point toward declaring a pest free area (PFA) of Kaphra beetle in Central Java. The survey employed the procedure established in Australia, except this survey lasted for 11 months starting from April 2008 to February 2009. Insect traps (Trécé Incorporation, Oklahoma, USA) were placed in eight sites distributed in six districts identified as high risk for Kaphra beetle. The traps were substituted following the label. The traps were checked every 2–4 weeks making the total observations varying from 18–24 times, except one site (eight times). No Kaphra beetle was observed during this detection survey. This finding strongly suggests that Kaphra beetle is not present in Central Java. Survey should be continued to collect data sufficient to declare PFA of Kaphra beetle.

Abstract

Soil microbes including actinomycetes are known to produce various hydrolytic enzymes and antibiotics that can be used as biological controlling agents nematode. Therefore, surveys conducted in several areas in Yogyakarta, Central Java and East Java, to search for actinomycetes with chitinolytic, proteolytic, and chitino-proteolytic activity. Isolation of Actinomycetes produced 84 isolates, and most was obtained from shrimp head waste (26 isolates). After the selection based on their ability to hydrolyze chitines and protein in the medium, those whith the highest chitin and protein hydrolysis activity, are consecutive PSJ 27, TL 8, and TL 10 isolates. Test results of crude enzyme produced by selected isolates against root-knot nematode eggshell, showed that the isolates that have chitino-proteolytic activity (TL 10), is a highly effective isolate in damage eggshell. There are three types of damage to the nematode eggs. In the young eggs, crude enzyme preparation causing damage on vitelline and chitin layers. In the older eggs, preparation of crude enzyme cause premature hatching.

Abstract

Powdery mildew is a fungal disease that causes subtantial losses in melon production around the world including Indonesia. Resistant melon cultivar to powdery mildew is important to increase melon production. Hence, the objectives of this study were to study melon resistance against powdery mildew and its inheritance. A F2 population was obtained from self pollination between F1 ♀ 371795 which derived from ♀ PI 371795 X ♂Action 434 and F1 ♀Action 434 which derived from ♀ Action 434 X ♂ PI 371795. In addition, a test cross population was produce by crossing between F1 with Action 434 as a recessive homozygote pa-rent. Furthermore, powdery mildew resistance in a F1, F2 and test cross populations were tested by inoculating powdery mildew which collected from Ngawi regency. The results were evaluated by Chi-square test (χ2). The results showed that a F1, F2 and test cross populations have different resistance levels to powdery mildew. The resistance to powdery mildew in a F2 ♀ PI 371795 population showed segregation and have 3:1 ratio of Mendel inheritance pattern. On the other hand, resistance to powdery mildew in a test cross with PI 371795 as a parent showed segregation with 1:1 ratio. While resistance in a F2 ♀ Action 434 and test cross populations with Action 434 as a parent did not express Mendel inheritance pattern. Based on the result it could be concluded thatn resistance to powdery mildew in PI 371795 as a female parent is controlled by a single dominant gene (pm-I), while resistance to powdery mildew in action 434 as a female parent is suppose to be controlled by several genes (oligogene).

Abstract

Tungro is one of rice disease caused by two different viruses (rice tungro virus=RTV) i.e. Rice tungro bacilliform virus (RTBV) and Rice tungro spherical virus (RTSV) that are transmitted only by green leafhopper. Tungro had become a serious problem in several rice productions centre in Indonesia. Various components of management effort have been applied but they were inefficient in preventing the tungro disease development. Resistance variety is the most efficient component to tungro disease management. Complexity interactions of tungro disease components are mayor constraint in tungro disease management. Detection of molecular variability in rice tungro virus from several endemic areas in Indonesia were conducted by using PCR-RFLP technique. Existence of RTBV and RTSV in the infected plants collected from several endemic areas were successfully detected by PCR. The RFLP analysis with restriction enzymes BstYI and HindIII showed that there were significant difference among the RTSV originated from Java, Bali and Sulawesi.

Abstract

Ralstonia syzygii is one of important pathogens of cloves. This study was aimed at obtaining pure culture of R. syzygi from diseased plant tissue samples. The acterium was isolated from infected clove plantations in Ungaran, Central Java. It had the ability to make clove seedlings show symptoms and then die 41 days after inoculation. The reisolated bacterium also showed its ability to kill clove seedlings after 17 days. The bacterium is gram negative, able to ultilize glucose, sucrose, maltose, mannitol, sorbitol, dulcitol, and glycerol, able to hydrolyze starch, grow well at 27oC, able to catalyze and release water and oxygen from hydrogen peroxyde (H2O2) and aerobically.

Abstract

In order to enhance food safety, the use of chemical pesticides on agriculture must be minimized, especially on postharvest processing. One of the alternative ways is the use of natural chitosan. Chitosan has good prospect as an alternative compound to chemical pesticides to be used on postharvest processing for agriculture products which are potential as exported commodity, such as banana cv. Ambon Curup, exotic fruit from Bengkulu. The aims of this research were to extract and characterize chitosan and to evaluate the inhibition of chitosan to Colletotrichum musae. Methods of experiment were (1) extraction of chitosan, (2) characterization of chitosan, and (3) inhibition test of chitosan to the pathogen in vitro. The parameters observed were the growth and colour of colony, the measurement and density of conidia and the dry weight of mycelium. The result indicated that the texture of chitosan were flake-powder with white-brownish colour, had a little bit odor of fish and pH were 7.5–13. The deacetylated degree of chitosan were around 74.27–75.64%. The in vitro test indicated that the kind of chitosan treatments gave no significant effect to the growth and colony colour, the measurement and density of conidia and the dry weight of mycelium. However the concentration of chitosan treatments were significantly effect all parameters. The chitosan on 20 mg/ml could inhibit the colony growth up to 81.20%, the conidial density up to 46.5%, the measurement of conidia up to 19.4%, and the dry weight of mycelium up to 59.46%. Chitosan had no effect to the colour of fungal colony.
