Abstract

In the complete life cycle of pink fungus, in this study five stages were recognized as follows: stage I (cobweb stage), stage II (pseudonodular stage), stage III (teleomorph), stage IV (nodular stage), and stage V (anamorph). The five stages are arranged into a sexual cycle (I, II, and III) on shady side of a branch, and asexual cycle (I, IV, and V) on exposed side of a branch. Most of the pink fungus on the 23 plant species found in this study formed only two or three stages of the sexual cycle. Only on apple, lime, calliandra, cinchona, coffee, oleander, crotalaria, and tephrosia, may the fungus form the complete five stages.

Abstract

Four parent isolates (189, Rh28, BW3 and F-1) of Thanatephorus cucumeris (anamorph: Rhizoctonia solani) AG 1-IC were induced to produce basidiospores using soil-over culture method. All of four parent isolates could produce basidiospores. Colonies obtained from single basidiospore isolate of each parent isolate were paired on charcoal potato dextrose agar. Single basidiospore isolate having different mating type produced tuft at area of the junction of paired colonies. On the based of tuft formation, single basidiospore isolates of each parent isolate could be divided into two different mating types, therefore it is concluded that each of 189, Rh28, BW3 and F-1 isolate of T. cucumeris AG I-IC has bipolar mating type.

Abstract

Susceptibility of the armyworm, Spodoptera litura (Fabricius) (Lepidoptera: Noctuidae) to nucleopolyhedrovirus was evaluated using droplet feeding methods. S. litura was originally collected from the field in Bantul and has been reared continuously in the laboratory using artificial diet. The tested instars were exposed a series concentration of nucleopolyhedrovirus (2×103, 2×104, 2×105, 2×106, 2×107, 2×108, 2×109 PIB/ml) which were added with Tinopal 0,5% and 1%. The result indicated that the larval mortality of 3rd, 4th, and 5th instars Tinopal, significantly different with the addition of 1% Tinopal. This addition increased the effectiveness of NPV for 235, 25117, and 6.6 million fold. The observation of the larval midgut which was treated by Tinopal, showed that Tinopal physically disrupt the peritrophic membrane. Therefore, it can be suggested that the Tinopal facilitates the entry of NPV to the host insect.

Abstract

Nucleotide sequence analysis of coat protein gene from two biological strains of peanut stripe virus (PStV), severe blotch (PStV-Isb) and stripe (PStV-Is), has been done to study molecular variation of these strains. Comparison of predicted amino acid sequence of PStV coat protein with other members of bean common mosaic virus (BCMV) subgroup was also carried out to study the taxonomic: relationship between PStV and BCMV subgroup. The CP gene from these strains contained 861 nucleotides (nts) and encoded 287 amino acids. There were seven nucleotides of the CP gene and one nucleotide of NIb cistron that were different between PStV-Is and PStV-Isb. However, only one nucleotide at position 9309 of the CP gene caused differential amino acid residue at position 49 of the coat protein, methionine (M) for PStV-Isb and isoleucine (I) for PStV-Is. Comparison of the ammo acid sequences revealed a sequence similarity of 89,9-90,9% of PStV and other BCMV subgroup. These results provide evidence that PStV and other BCMV subgroup are in the same virus with different strain.

Abstract

Sciarid fly (Bradysia ocellaris Comstock) population growth and its distribution in the mushroom house was studied. Insects were collected using sticky yellow traps laid on 21 stations in the house over 18 weeks. At the first time, insects population was low. After that, insect population grew and reached at a maximum level in the 8th week. In subsequent weeks, insect population fluctuated. In the other hand, insect population dispersal also occured in the house. Based on spatiotemporal analysis using contour map and semivariogram analysis, insect population showed aggregation pattern, in a small group is called subpopulation. This was related to biological characters of insect such as eggs oviposition in mass and short flights.

Abstract

The objective of this study was isolation and characterization of Soybean Stunt Virus, the causal agent of soybean stunt disease. The virus was isolated with single lesion method through Chenopodium amaranticolor and Vigna unguiculata, and then propagated on Nicotiana tabacum var. Xanthi. Differential centrifugation method was used for purification. Virus isolate obtained from Bogor was used for futher studies. The result showed that SSV could be isolated on C. amaranticolor, but not on V. unguiculata and then propagated on Niconana tabacum var. Xanthi without any symptom. Purified virus showed A260/A280 = 1.55, lower than that of CMV. The virion were small isometric particles, about 30 nm in diameter. Coat protein consists of a single type of subunit protein, with molecular weight about 29 kD.

Abstract

The study was carried out in Gunung Kidul Regency of Yogyakarta special. Dried cassava was taken from the district of Nglipar (north zone), Wonosari (center zone), Semanu and Rongkop (south zones) for identification of the genera of Aspergillus growing on the samples. Clasification of the zones was based on the degree of rainfall on the area. Dichloran 18% Glyserol Agar (DG-18) medium was used for isolating pathogen, while Czapek Yeast Extract Agar (CYA), Czapek Yeast Extract Agar with 20% sucrose (CYA 20S) and Malt Extract Agar (MEA) media were used for identification. The fungi were identified on the basis of both macroscopic and microscopic morphologies. The result showed that The Genera Of Aspergillus growing on dry cassava were A. flavus, A. niger, A. oryzae, A. foetidus, A. zonatus and A. tamarii. A. flavus was a predominant fungus that grow on dry cassava.
