Abstract

Corn borer is one of the important pests on corn plant in Gorontalo Province, especially in three districts which are the center of maize planting development. Corn borer and its natural enemy complex in Gorontalo Province has not been clearly studied. The purpose of this study is to determine the complexity of the natural enemies of maize stem borer by calculating the diversity and composition. The survey method was used, in which the older larvae, pupae, and corn borer natural enemies were collected from the field in the three districts (Gorontalo, Boalemo, and Pohuwato). Observation plots in each district area of 2,500 m2, were divided into 3 sub plots with the size of 3×3 m, each plot is consisted of 45 plants at the spacing of 75×25 cm. The data were analysed descriptively and organized into tables. Shannon Index was used to count the diversity and composition of the pests and their natural enemies. The results showed that the corn borer species was Ostrinia furnacalis, while the dominant natural enemy was the tachinid fly. The analysis of Shannon diversity index for natural enemies of three districts of Gorontalo, Boalemo, and Pohuwato were 0.63, 0.61, and 0.97 respectively.

Abstract

Chrysanthemum white rust (CWR) caused by Puccinia horiana creates severe losses on chrysanthemum (Chrysanthemum grandiflorum, Dendranthema grandiflora) in plastic houses in Bandungan (750–1050 masl.) and its surrounding. In lower elevations higher disease intensities were found around roof leakages and ventilations. In Sumowono (1000–1050 masl.) the disease was spread evenly in plastic houses. Teliospores of P. horiana develop in form of basidia (promycelia) at midnight which directly form basidiospores (sporidia). Spreading of basidiospores occur at 2 to 4 in the morning, especially at 3 a.m. Infection takes place through lower or upper surface of the leaves, as the two sides have stomata. Incubation time in this trial is 8–11 hours. Vegetative as well as generative phase of chrysanthemum have the same susceptibility. Many farmers applied inappropriate fungicides in controlling CWR. It is recommended to apply carbendazim as systemic fungicide alternated by protectant fungicides as mancozeb.

Abstract

Study on the role of initial inoculums on disease development of rice sheath blight caused by Rhizoctonia solani Kühn was conducted in glass house at the Faculty of Agriculture University of Gadjah Mada from December of 2009 to July of 2010. The aim of this study was to evaluate the importance of sclerotia and mycelium in plant debris as primary inoculum form of R. solani. Results indicated that both sclerotia and mycelium in plant debris significantly affect the development of rice sheath blight. Disease severity was closely related to the number of sclerotia on rice plant. The highest disease severity was observed in plant inoculated with 10 sclerotia per hills. Treatments of 6 sclerotia and 5 g plant debris per hills had comparable effect on disease severity and area under disease progress curve of rice sheath blight. The results suggested that sclerotia and mycelia in plant debris might play a major role as primary inocula of the disease in rice growing field.

Abstract

The study aims to identify of white grub attacking lawn in the park of campus of University of Gadjah Mada (UGM), Yogyakarta. Observations were conducted since July 2008 until January 2010. The results showed that Lepidiota stigma is a pest cause damage to the grass in the UGM park. The presence of beetles occurred in October of the same beginning of the rainy season. Flight and lay eggs period lasted from October 2009 until January 2010. First instar larvae of L. stigma began there in November and the third instar in the month of January 2010. Factors supporting the attack of L. stigma in the college environment is the availability of grass throughout the year, as the lights and the presence of trees as shelter for adult beetles.

Abstract

Geminivirus infection has caused severe losses on various economically important crops. The disease incidence on melon has been observed since 2004, and widespread at melon production centers in East Java and Special Province of Yogyakarta. In East Java and Special Province of Yogyakarta, the Disease Incidence of leaf curl on melon  reached 100% and 14.3 % respectively in 2008. Detection of the causal agent using primers of CPA5 and CPA2 resulted viral specific DNA fragment of 770 bp.

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

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.
