The experiment was conducted based on damage developed on pine nursery, which killed pine seedlings at a significant number. The damage started on 4 month-aged seedlings indicated by yellowing of needle, followed by development of brown spots on the needle and subsequently could kill the transplanted seedlings. Application of formulated Trichoderma and slow released fertilizer was aimed to avoid the initial symptom, which was assumed due to nutrient deficiency and to control the subsequent infection and disease development. Substitution of composting materials and rice hull into regular growth medium as the main treatment resulted 4 combination treatments. The results indicated that despite all treatments showed significant effects, application of Trichoderma together with slow released fertilizer (PJTJ) on regular medium (medium IV) gave the highest growth increment performance and suppression of damage in seedlings.

Sugarcane (Saccharum officinarum L.) is very important commodity in Indonesia because of its economical value as a sugar producing plant. One of the disease in sugarcane cultivation which have to be treated is mosaic symptoms because of its potency in reducing sugar yield. Mosaic symptoms might be caused by some viruses, therefore virus identification is required to find the virus that has caused the sugarcane disease in all of sugarcane field which can be found in East Java as working area of Seeding and Protection Center for Estate Crops Surabaya. This laboratory had an authority to certify the shoot to be distributed. This research aimed to find out the virus that caused the mosaic symptoms from nine sugarcane varieties and to obtain information about the most suitable identification method for shoot health test in Seeding and Protection Center for Estate Crops Surabaya. The first method of this research were the sugarcane leaf with mosaic sampling from nine varieties: VMC 7616, PSJK 922, Kidang Kencana and Tolangohula 2 (Jombang); PS 881 and PS 862 (Pasuruan); PS 864 dan PSBM 901 (Kediri). The next experiments were conducted in the Laboratory of Phytopathology, Faculty of Agriculture, Universitas Gadjah Mada. RNA was isolated from the sample and continued with RT-PCR technique, sequencing and bioinformatic analysis. Primers which was used in this research were MJ1-MJ2 and SCSMV cpF – SCSMV AP3. The result showed that mosaic symptoms of eight sugarcane varieties was caused by two species of virus: SCMV (Sugarcane mosaic virus) found in PS 881 and SCSMV (Sugarcane streak mosaic virus) found in seven another varieties. Sequencing analysis showed that SCMV isolate found in PS 881 was known to have a high nucleotide homology (93.6%) and related to the isolate from Kenya (KT630805.1), while the SCSMV had a high homology (96.9%−98.5%) and related to SCSMV isolate from Indonesia (AB563503.1) and Pakistan (GQ388116.1). INTISARITebu (Saccharum officinarum L.) merupakan tanaman penting di Indonesia. Salah satu penyakit yang perlu diwaspadai pada tanaman tebu adalah penyakit mosaik karena potensinya dalam menurunkan produktivitas tebu sehingga perlu dilakukan identifikasi virus penyebab mosaik pada tanaman tebu. BBPPTP Surabaya sebagai instansi yang melaksanakan sertifikasi pada bibit tebu perlu mengetahui metode identifikasi virus penyebab mosaik sebagai dasar dalam pengujian kesehatan benih untuk mendukung tersedianya bibit tebu yang sehat. Penelitian ini bertujuan untuk mengetahui virus penyebab mosaik pada sembilan varietas tanaman tebu dan mengetahui metode identifikasi virus pada tanaman yang cepat dan akurat untuk pengujian kesehatan benih. Penelitian dilakukan di Laboratorium Fitopatologi, Fakultas Pertanian Universitas Gadjah Mada. Penelitian dilakukan dengan mengambil sampel daun tanaman tebu pada sembilan varietas yang diambil dari tiga lokasi berbeda yaitu VMC 7616, PSJK 922, Kidang Kencana dan Tolangohula 2 (Jombang); PS 881 dan PS 862 (Pasuruan); PS 864 dan PSBM 901 (Kediri). Sampel diisolasi ss-RNA dilanjutkan dengan teknik RT-PCR (Reverse-Transcription Polymerase Chain Reaction), sekuensing dan analisis bioinformatika. Primer yang digunakan dalam penelitian ada dua yaitu MJ1-MJ2 untuk target sekuen dari SCMV dan SCSMV cpF-SCSMV AP3 untuk target sekuen dari SCSMV. Hasil penelitian ditemukan bahwa gejala mosaik yang ditimbulkan pada 8 (delapan) sampel varietas tebu disebabkan oleh 2 (dua) jenis virus penyebab mosaik yaitu SCMV (Sugarcane mosaic virus) yang ditemukan pada varietas PS 881 dan SCSMV (Sugarcane streak mosaic virus) yang ditemukan pada 7 (tujuh) varietas lain. Analisis sekuensing menunjukkan bahwa SCMV yang ditemukan pada varietas PS 881 memiliki homologi nukleotida (93,6%) dan kekerabatan terdekat dengan isolat di Kenya (KT630805.1). SCSMV hasil penelitian ini dikatakan mempunyai homologi (96,9%−98,5%) dan kekerabatan tertinggi dengan isolat SCSMV asal Indonesia (AB563503.1) dan Pakistan (GQ388116.1).

Publisher : Universitas Gadjah Mada

Response of a population of the European corn borer, Ostrinia nubilalis (Hubner), to selection with an ecdysone agonist, tebufenozide (RH-5992), was investigated. The selection was carried out by exposing newly hatched larvae of O. nubilalis on an artificial diet containing 0.285 ppm tebufenozide for four days. Throughout seven generations of selection, a slight decrease in the larval mortality, an increase in the pupal mortality, and a decrease in the number of offspring produced per female were noticed. After four generations of selection, a shift in susceptibility of the selected O. nubilalis larvae to tebufenozide was not observed. The acute and chronic effects of tebufenozide caused the loss of O. nubilalis population after seven generations of selection.

Oviposition preference of a predatory hoverfly, Episyrphus balteatus on the presence of its potential predators, the ladybird larvae which are inflicted serious impacts on its eggs was examined in a non-choice test. Our results revealed that the biggest and the most aggressive species of ladybird, Harmonia axyridis caused the worst impact on hoverfly eggs by attacking and feeding on. The species and developmental stages of ladybird were attributed to the level of predation risk. We correlated the oviposition site selection by hoverfly females to the egg predation risk level inflicted by ladybird larvae. Hoverfly females laid the least number of eggs on the patches attended by the strongest competitor, the larva of H. axyridis, and tended to lay the highest number of eggs on colonies attended by the weakest competitor, the larva of Scymnus posticalis. In addition, the impact of the fourth instar larva of ladybirds was stronger than of the first instar larva.

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.

Methyl eugenol (= ME) is an insect attractant. It is known that male Bactrocera dorsalis is attracted to ME. The objective of this research is to examine the effects of ME consumption on mating behavior and its success of Bactrocera carambolae. Observations were done daily from 17.00 to 18.00 hours. Mating success was characterized by the occurrence of copulation between male and female flies while mating behavior analysed by their fight intensities and wing vibrations. The results showed that the fighting and wing vibration periods of ME consuming flies were longer than those which did not. Mating success of those flies which fed on ME was relatively higher. It was concluded that ME is a stimulant for enhancing mating success of Bactrocera carambolae.

Diaphorina citri Kuwayama (Hemiptera: Psyllidae) is the vector of citrus greening (Huanglongbing) bacterium and the most serious impediment to citrus culture. Classical biological control of this psyllid vector should contribute to suppress their population. This research was conducted to determine the performance of Menochilus sexmaculatus Fabricius (Coleoptera: Coccinellidae) when they were fed with D. citri. The larval performance index of M. sexmaculatus on D. citri compared with Aphis craccivora Koch (Hemiptera: Aphididae) diet was 1.3.M. sexmaculatus fed with D. citri had lower fitness than those fed with A. craccivora as shown by longer larval stadium, lower adult dry weight, less number of egg produced and lower percentage of egg hatched. M. sexmaculatus grew best at the temperature of 27oC. Employing the exclusion procedure under field condition,M. sexmaculatus could reduce the population of D. citri up to 90%. These findings showed that theM. sexmaculatus could be a potential predator in reducing D. citri, particularly when the more preferred prey A. craccivora was not present.

Bacterial diseases in plants are difficult to control. The emphasis is on preventing the spread of the bacteria rather than curing the diseased plant. Integrated management measures for bacterial plant pathogens should be applied for successfull control. Biological control is one of the control measures viz. through the use of microorganisms to suppress the growth and development of bacterial plant pathogen and ultimately reduce the possibility of disease onset. The study of biological control of bacterial plant pathogen was just began compared with of fungal plant pathogen. The ecological nature of diverse bacterial plant pathogens has led scientists to apply different approach in the investigation of its biological control. The complex process of entrance to its host plant for certain soil-borne bacterial plant pathogens need special techniques and combination of more than one biological control agent. Problem and progress in controlling bacterial plant pathogens biologically will be discussed in more detail in the paper and some commercial products of biological control agents (biopesticides) will be introduced. Penyakit tumbuhan karena bakteri sulit dikendalikan. Penekanan pengendalian adalah pada pencegahan penyebaran bakteri patogen dan bukan pada penyembuhan tanaman yang sudah sakit. Untuk suksesnya pengendalian bakteri patogen tumbuhan diperlukan cara pengelolaan yang terpadu. Pengendalian secara biologi merupakan salah satu cara pengendalian dengan menggunakan mikroorganisme untuk menekan pertumbuhan dan perkembangan bakteri patogen tumbuhan dengan tujuan akhir menurunkan kemungkinan timbulnya penyakit. Sifat ekologi bakteri patogen tumbuhan yang berbeda-beda mengharuskan pendekatan yang berbeda pula dalam pengendaliannya secara biologi. Masalah dan perkembangan dalam pengendalian bakteri patogen tumbuhan secara biologi didiskusikan secara detail dalam makalah ini.

One of the pathogen infecting peanut in Indonesia is Peanut stripe virus (PStV,), causing stripe and blotch symptoms on infected peanut leaves. The objectives of this research were to evaluate effects of PStV infection on yield of 10 introgression lines of peanut derived from crossing of Arachis cardenasii and A. hypogaea, and to determine the tolerance of these lines against PStV infection. Peanut plants were grown in polybag containing 10 kg of potting soils and were grown under glasshouse conditions. The experimental unit consisted of four plants grown separately in four containers and for each treatment was replicated four times. Peanut plants were inoculated mechanically with Bogor isolate of PStV at 15 days after planting (dap) and harvested at 95-100 dap. Results of the experiment indicated peanut cv. Gajah belonged to moderate tolerance while Kelinci was sensitive against PStV infection. Introgression line NC-CS11, CS30 and WS4 were grouped as tolerance while NC-CS51, WSl, and WS3 were moderate tolerance. The tolerance lines showed mild mosaic symptoms, did not show reduction of plant height and peanut yield upon inoculation with PStV. Introgresion line NC-CS15, CS20,CS22, and CS50 were sensitive against PStV infection, showed moderate to severe mosaic/blotch symptoms, reduction of plant height and peanut yield due to PStV infection. Among the tolerance and moderate tolerance lines, only NC-CS30 showed higher yield as compared to peanut cv. Gajah or Kelinci. Therefore, this line may be developed further as commercial peanut cultivar or be use as donor germplasm for PStV tolerance mechanisms in peanut breeding.

Imidacloprid is a neonicotinoid insecticide that is recommended for controlling Nilaparvata lugens. In Asian countries, such as, China, Vietnam, India, and Thailand, imidacloprid has caused resistance to N. lugens. Imidacloprid has also caused resistance to N. lugens based on some previous studies in Indonesia. The aim of this study was to determine the fitness and feeding capacity of imidacloprid-resistant N. lugens. The population of N. lugens used in this study had a resistance level of 50.64 times compared to the susceptible population. When the resistant and susceptible population of N. lugens did not receive any exposure to imidacloprid, the susceptible population had better fitness than the resistance one. However, the fitness of the resistant population increased when this population was resistance which sublethal cencentration (LC50 & LC20) of imidacloprid. The increase fitness of this resistant population most likely related to the increase in feeding capacity of the resistant population when they were treated which sublethal imidacloprid. These findings suggest that the field population of N. lugens that have developed resistance would increase the probability of outbreak if they were sprayed with imidacloprid. INTISARI Imidakloprid adalah insektisida neonicotinoid yang direkomendasikan untuk mengendalikan Nilaparvata lugens. Di negara Asia, seperti, China, Vietnam, India, dan Thailand, imidakloprid telah menyebabkan resistensi terhadap N. lugens. Di Indonesia, berdasarkan beberapa penelitian sebelumnya dilaporkan imidakloprid juga menyebabkan resistensi terhadap N. lugens. Tujuan penelitian ini untuk mengetahui kebugaran relatif dan kemampuan makan N. lugens resisten terhadap imidakloprid. Populasi N. lugens yang digunakan dalam penelitian ini mempunyai tingkat resistensi 50,64 kali dibandingkan dengan populasi peka. N. lugens populasi resisten dan peka apabila tidak dipapar dengan imidakloprid, populasi peka mempunyai kebugaran lebih baik dari pada resisten, namun kebugaran dari N. lugens populasi resisten meningkat ketika populasi tersebut dipapar dengan imidakloprid konsentrasi subletaal (LC50 & LC20). Peningkatan kebugaran populasi N. lugens resisten diduga terkait dengan peningkatan kemampuan makan akibat dipapar lagi dengan imidakloprid subletal. Hasil penelitian ini menunjukkan bahwa ledakan N. lugens akan terjadi, apabila populasi N. lugens yang telah resisten terhadap imidakloprid dipapar lagi dengan imidakloprid.
