Abstract

Stem Canker: A New Disease of coffee in LampungStem cancer is a new disease that has attacked smallholder coffee plantations in Lampung since 2010. The cause of the disease was unknown. This study aims to describe the symptoms of the disease, the incidence of the disease in the affected plantation, and identify morphologically and molecularly the canker pathogens of the coffee stem canker diseases. All stages of Koch’s postulate were carried out in laboratories and greenhouses. The isolated pathogens were morphologically characterized by colony shape and color as well as the conidia shape and size. Molecular identification was carried out by using a general primer (ITS1 and ITS4) and followed by sequencing. The main symptoms of the disease are stem cancer and dieback, as well as more infecting older plants. Pathogen of the coffee stem canker disease that attacks coffee plants in Lampung has been identified as Fusarium solani which has 99% homology with F. solani KY245947.1.

Abstract

Increasing productivity of soybean has often been constrained by pod sucking bugs (Riptortus spp.) which caused a serious damage  and yield losses up to 80%. Breeding for obtaining soybean variety resistant to pod suckers needs the availability of soybean germplasm resistant to the pest. The study aimed to obtain a candidate for soybean variety resistant to Riptortus spp. through the selection of 100 accessions of soybean. The study included the preparation of test plants and test insects, pest infestations, observations, and looking for a practical screening method for pod sucking pests. The experiment used a completely randomized design for two treatments (infested and non-infested Riptortus spp.). Cikuray variety and PI-092734 accession were used as a control. Results showed that there was a very low correlation among variables observed. Twelve soybean accessions showed a resistance to Riptortus spp., i.e. C7301-113AC-POP, Lokal Madiun-3549, Lokal Klungkung, ML.2974, Singgalang, Lokal Jepara, Lokal Jatim, Lokal Trenggalek, Lokal Tulungagung, Lokal Tabanan, Lokal Blitar, and Lokal Kuningan 10. These accessions were more resistant than the popular released variety such as Wilis, Grobogan, Detam 2, and Gepak Ijo. Small seed size was not a major determinant of soybean resistance to pod suckers. The addition of observational components, i.e. probing preference and oviposition, indicated that crop damage was indirectly influenced by the high frequency of probing and oviposition, although its relation to plant tolerant mechanisms still needs further investigation. Indeterminate plant types require further validation as to whether they contribute significantly to plant resistance against pod sucking insects.

Abstract

Variation within bulb tunics has been used to determine the genetic diversity in Allium species, including shallots. However, no such study has been reported for shallots of Indonesia. The study aimed to analyze the genetic diversity of the Indonesian shallots based on the bulb-tunic patterns. Thirty-five shallot genotypes from main production centers in Indonesia were used. The ultrasculptures of the bulb tunics were examined by light microscopy, including the inner surface and cell shape patterns of the bulb tunics. The phenotypic data, i.e. quantitative and qualitative traits were subjected to the descriptive statistics, principal component, correlation, regression, and clustering analyses. The results showed that the bulb-tunic cell patterns were varied, which shared almost identical with 13 Allium species. Total bulb weight per genotype showed the greatest variation (cv = 89.10%) and significant correlation with bulb weight per plant (r = 0.773). The principle component analyses showed the cumulative proportion of 78% of the total morphological variation in all shallot genotypes. Based on clustering analysis, the genetic variation of Indonesian shallots are grouped into twelve clusters with 50% genetic similarity. The study indicates that Indonesian shallots are genetically varied and could be useful for further utilization in their genetic improvement program.

Abstract

Resistance Response of Several Wheat Varieties Against Pest of Stored Product, Sitophilus zeamais (Coleoptera: Dryophthoridae). Lina Herlina and Bonjok Istiaji. Since Sitophilus zeamais still become the major pest of wheat as stored product. Twelve varieties of wheat were evaluated for their resistance to the infestation of S. zeamais. The study was conducted at the Laboratory of Insect Specimen Collection of Indonesian Center for Agriculture Biotechnology and Genetic Resource Research and Development (ICABIOGRAD) from September 2011 to February 2012. Grains of each 12 varieties of wheat was weighed for 5 grams and placed into a plastic bottle. Six female imagos of S. zeamais (1 week old) were introduced into the bottle contained 5 grams of wheat grains. After seven days, all the insects were removed. Observation were done to count the dead and life insects after introduction. The number of larvae emerged from eggs were calculated and weighed daily. Grain weight of each variety was also weighed, the broken and intact seeds were counted and recorded at the end of the infestation. Research were conducted in randomly complete design using one factor, that was twelve varieties of wheat each were replicated three times. The result showed that the highest mortality of the pest were in Perdix, while the lowest were that in Anemos, Combi, and Nandu (0-16.7%). The highest fertility of the pests were found in the Anemos and SW Triso, while the lowest were there in Picallo (14.33-47.67 insects). Anemos was known to be variety with the highest insects population weight, while the Picallo was the variety that inhibited insect population (0.0161-0.0544 g). The longest of insect development periods was on Combi, the shortest was on Sweta (51.33-64.33 days). The shortest median development time was in the Anemos and the longest was in the Sit Nortrend (37.33-44 days). The highest percentage of seed damage and yield loss were in the Anemos, while the lowest were Picallo and Madonna. ANOVA at 5% showed no significant different for all parameters observed on the tested varieties. Resistance classification based on the indexes of Modification, Pointe and Dobie recorded that the most resistant varieties were Picallo and Pasadena. AbstrakSitophilus zeamais masih menjadi hama utama pada produk pascapanen. Penelitian dilakukan di Laboratorium Koleksi Spesimen Serangga BB Biogen dari September 2011 sampai Februari 2012 untuk mengevaluasi ketahanan 12 varietas gandum terhadap infestasi S. zeamais. Biji 12 varietas masingmasing ditimbang 5 g dan dimasukkan ke dalam botol plastik, kemudian diintroduksikan enam imago betina S. zeamais berumur seminggu. Setelah tujuh hari, seluruh serangga dikeluarkan, dihitung yang mati dan yang masih hidup. Jumlah larva (progeni F1) yang muncul dari telur diamati dan dihitung setiap hari. Berat gandum tiap varietas ditimbang pada akhir percobaan. Biji yang berlubang maupun yang masih utuh dihitung dan dicatat. Penelitian menggunakan rancangan acak lengkap satu faktor, yaitu jenis varietas gandum sebanyak 12 varietas, masing-masing dengan tiga ulangan. Hasil percobaan menunjukkan bahwa mortalitas larva tertinggi ditemukan pada varietas Perdix, sedangkan terendah pada Anemos, Combi, dan Nandu (kisaran 0-16,7%). Fertilitas tertinggi ditemukan pada Anemos dan SW Triso, sedangkan terendah pada Picallo (kisaran 14,33-47,67 ekor). Bobot tertinggi larva serangga ditemukan pada Anemos, terendah pada Picallo (kisaran 0,0161- 0,0544 g). Perkembangan serangga terlama ditemukan pada Combi dan terpendek pada varietas Sweta (kisaran 51,33-64,33 hari). Waktu paruh terpendek pada varietas Anemos dan terpanjang pada varietas Sit Nortrend (kisaran 37,33-44 hari). Kerusakan biji maupun kehilangan hasil tertinggi pada varietas Anemos, sedangkan terendah pada Picallo dan Madonna. Hasil ANOVA pada taraf 5% menunjukkan tidak terdapat perbedaan pengaruh yang signifikan dari seluruh varietas terhadap semua parameter yang diamati. Berdasarkan indeks Modif, Pointe maupun Dobie, varietas yang paling tahan adalah Picallo dan Pasadena.

Abstract

Control of Plutella xylostella L. can be done both biologically and chemically. Biological control is generally done by utilizing plant extracts to kill insect pests. This study aims to determine the effect of the extract of seeds on the mortality and development of parasitoid Diadegma semiclausum Hellen and its host, P. xylostella. The effect of Srikaya seed extract on P. xylostella larvae in the initial stage was tested by foliar rest method, while the residue method on the glass surface was used to test the effect of the extract of seed extract of Srikaya on the death of imago D. semiclausum. The effect of seed extract on parasitization and development of D. semiclausum was performed by exposing P. xylostella larvae contaminated by the extract of srikaya seeds in sublethal concentration (LC5 and LC10) in imago D. semiclausum. The results showed that extract of srikaya seeds at a concentration of 0.0632–0.1% at 24-hour contamination affected the death of the larva P. xylostella and the imago parasitoids D. semiclausum. Imago parasitoids are more susceptible to increased concentration of extracts than P. xylostella larvae. The developmental resistance of P. xylostella by Srikaya seed extract at concentrations used is generally unreal. Similarly, the barriers to the development of parasitoid D. semiclausum in hosts contaminated with sublethal concentrations (LC5 and LC10) of seed extract are generally not significantly different. The presence of Srikaya seed extract in the host also has no significant effect on the extent of parasitization, cocoon length, cocoon width, and cocoon weight. Therefore, there is a possibility to chemically and biologically integrate P. xylostella control.

Abstract

Rat is important pest especially in rice field. This program aims to find out effectiveness of using owl as biological control of rice field rat and compare them with other controls. The program is located in Bener village, Wonosari, Klaten. The method of the program are interview and observation. The result showed that the application of owl has not been use optimally. Making owl nest box that’s not according to the standard make owl reluctant to the owl nest that has been made. In addition, there is lack of public awareness of synchronously control, so it makes rat’s attack increase. Control of rat does not rely on owl as its predator, but it’s also combined with other controls like gropyokan, emposan, and toxic bait synchronously and continuously so it can achieve success in decreasing of development rice field rat. Keywords: owl, owl nest box, rice field rats
