Abstract

Spodoptera frugiperda is a novel invasive pest of maize crops. Therefore, studies on this pest are limited. Research on the use of artificial diets in S. frugiperda larvae rearing is essential to facilitate the provision of test larva stocks for lab-scale study purposes. The aim of this research was to figure out the effect of an artificial diet from soybeans as a protein source on S. frugiperda rearing. The parameters observed in this research were larval-stage longevity, larval survival rate, pupa size, sex ratio, pupal-stage longevity, pupal survival rate, fecundity, and nutritional index. The results showed that an artificial diet with soybeans had a significant effect on sex ratio, pupal survival rate, relative consumption rate (RCR) 4.89 g/g/day (4th instar); 1.99 g/g/day (5th instar), approximate digestibility (AD) 98.39% (4th instar); 95.45% (5th instar), and fecundity, but it did not have any significant effect on larval-stage longevity, larval survival rate, pupa size, pupal-stage longevity, the efficiency of conversion of ingested food (ECI) 3.68% (4th instar); 7.84% (5th instar), and efficiency of conversion of digested food (ECD) 3.76% (4th instar); 8.27% (5th instar). Artificial diet-based soybean was highly potential to be used in S. frugiperda rearing.

Abstract

Indonesia is an agricultural country with more than 30 million farmers nationwide most of it with poor disease management. An identification of a pathogen is the first step to establish efficient management strategies for disease control. In this study, we survey the diversity of oomycetes in horticulture. Samples were collected from 19 sites around Lampung, Sumatera and Java Islands. The oomycetes were isolated from rhizosphere soils sample and from symptomatic plants tissues. One hundred and twelve isolates belonging to two Phytophthora spp., three Pythium spp., and one Phytophythium sp. were identified. Phytophthora nicotianae was a predominant species from pineapple but also found in cabbage, chilli, and chrysanthemum. P. colocasiae were isolated from taro in central java, Phytopythium vexans were isolated from potato in Central Java, while Pythium acanthophoron, Py. myriotylum, Py. splendens, and Py. catenulatum were isolated from soil in pineapple farms.

Abstract

Rust leaf disease is the main disease on chrysanthemum (Dendranthema grandiflora) plantations in the district of Sleman, Yogyakarta Special Region. In 2006, the symptoms of leaf rust were initially found in chrysanthemum farms in village of Hargobinangun and surrounding areas. Since then it has been consistently spreading to other areas throughout Yogyakarta-Indonesia. Puccinia horiana is closely associated with rust leaf disease. This research was aimed to investigate the distribution, incidence, and severity of chrysanthemum rust disease in chrysanthemum plantations in Yogyakarta. The survey was conducted based on a randomized stratified approach. The entire district was divided into five observation sites, with each location consisting of three to four chrysanthemum farm sites owned by farmers. The results showed that rust leaf disease was distributed in all sites. The average of disease incidence found in the observation sites was 97.13%, meanwhile the average of disease severity was 55.19%. The highest disease incidence was found in Kaliurang 98.44%, followed by Wonokerso of 98.33%, Gondanglegi of 96.87%, Boyong of 96.25%, and Sidorejo of 95.83%. The highest disease severity was found in Wonokerso 58.75%, followed by Gondanglegi 56.92%, Kaliurang 53.39%, Sidorejo 54.89%, and Boyong 52.01%. The lower plant cultivation site, the lower incidence of rust disease.

Abstract

Piper yellow mottle virus (PYMoV) is the dominant virus that causes mottle disease in black pepper (Piper nigrum). Two species of mealybugs, Ferrisia virgata and Planococcus minor have been reported as vectors of PYMoV. A different species of mealybug that has never been reported before was found in black pepper. Molecular approaches including total DNA isolation of mealybug collected from the field, mealybugs identification by DNA barcode, detection of PYMoV in single mealybugs, were conducted as an approach to identify the potential of mealybugs as PYMoV vector in the field. Mealybugs were collected from black pepper plants in Cimanggu (Bogor, West Java) and Sukamulya (Sukabumi, West Java). Characters of adult females were observed for morphological identification. Molecular-based identification of the mealybugs and PYMoV involved the following procedures: total DNA isolation, DNA amplification, nucleotide sequencing and sequence analysis. Three species of mealybugs, P. minor, F. virgata and Paracoccus marginatus were confirmed by morphological and molecular identification. This is the first report for the occurrence of P. marginatus in black pepper plants. PYMoV was successfully detected from field samples of F. virgata, P. minor and P. marginatus. This finding indicates the potential of insect vectors for disease spread and distribution.

Abstract

Efforts to increase rice production and productivity nationally are still being disturbed by plant pest organisms. One of the diseases that have received serious attention is the tungro disease, which has the ability to attack rice plants in endemic areas. The purpose of this study was to investigate the resistance of several rice lines towards the Lanrang South Sulawesi tungro virus inoculum including morphological characteristics. This study was conducted at the Tungro Disease Research station from June to September 2020. A total of 14 lines were tested for resistance compared to the Tukad Petanu, Tukad Balian, Inpari 8 and Tukad Unda lines against the tungro disease. The rice lines were planted in the form of an augmented design consisting of five blocks. Each block contained three test lines and four comparison varieties, the lines were planted in plots (1 × 5) m, with 25 × 25 cm spacings. The results showed that the population of green leafhoppers at the age of 20 DAP and 30 DAP was found to range from 1 to 95 individuals per line/variety, while the incidence of tungro disease was 1.3 to 11.3% in the three test lines, namely STLRG17 15 LR 1, STLRG17 15 LR 2, and STLRG17 108 LR 1. The highest 1000 seed weight was found in the STLRG17 176 LR 2 line (25.1 g) and the lowest was STLRG17 51 LR 1 (17.6 g). The STLRG17 175 LR 1, STLRG17 176 LR, STLRG17 -175-LR-1, STLRG17-28-LR-1, and STLRG17-26-LR-2  5 lines had a fairly good and consistent appearance at 1000 seed weight, higher yield, productive tillers, plant height, and resistance to tungro disease compared to the comparison varieties.

Abstract

Tungro disease severity and agronomic characteristics of tungro-resistant lines. Tungro is one of the diseases problem in rice production. The simplest approach to solve the problem is to use the resistance tungro variety, which is made of tungro resistance lines. At present, the character of the new type of rice becomes a preference by the formation of a variety. The line with the character of Agronomy is a decisive factor in the choice of a variety by farmers. The aim of this study was to evaluate the potential tungro resistant lines according to severity and agronomy. The research was carried out in the dry season of 2015 in Polewali Mandar, West Sulawesi. Fifty promising tungro lines and four reference varieties were tested using the Augmented Design with five blocks as replicates. Variables observed were green leafhopper population density and the presence of tungro disease. Agronomic character variables observed included clump shape, productive tiller at 90 DAT, flowering age 50%, the weight of 1000 grains, filled and unfilled grain, and grain yield of kg/ha. The results showed that there were several lines that had significantly higher yield potential , i.e. BP3734A-3-15-LRG-5-8-2-5, BP3770A-1-218-LRG-2-3-1-9, BP3840A-6-253-LRG-8-6-2-8, BP3862A-21-1054-LRG-5-1-1-6, BP3866A-4-1207-LRG-9-3-2-7, BP3870A-4-1357-LRG-2-3-1-7 and BP3870A-4-1363-LRG-8-1-1-7. All of these lines have the potential to be processed to the next phase.

Abstract

Rhizoctonia solani and Xanthomonas oryzae pv. oryzae (Xoo) are important pathogens causing severe damage on rice. It makes severe damage and is required for the management of the disease. One of the management of the disease is the use of endophytic bacteria. The purpose of this study was to determine the compatibility of endophytic bacteria as consortium, to examine the potency of the endophytic bacteria consortium against R. solani and Xoo and to understand the mechanism of inhibition of endophytic bacteria consortium against R. solani and Xoo. Assessment on the compatibility between endophytic bacteria was performed in a petridish using streak method. The endophytic bacterial consortium antagonism test against rice pathogenic fungi and bacteria was carried out in a completely randomized design with 2 treatments and 15 replications. The variables observed were the compatibility of endophytic bacteria, the percentage of inhibition and the zone of inhibition. The mechanism of inhibition was observed from changes in the form of pathogenic fungi and bacteriostatic or bactericidal. The results showed that among 12 compatible endophytic bacteria as constituents of the consortium, five isolates of endophytic bacteria showed strong and very strong growth with the other isolates. These isolates from Petanahan Kebumen, Karangwangkal Purwokerto and Sumbang Banyumas. The consortium of endophytic bacteria was able to suppress the growth of R. solani by 57.14% with antibiosis mechanism causing swelling of the mycelium and formed a red pigment. The endophytic bacteria consortium inhibited the growth of Xoo by 15 mm with a bacteriostatic antibiosis mechanism. Consortium endophytic bacteria can be used as an alternative to control plant diseases which also has the opportunity to be formulated and applied to plants.

Abstract

The whitefly Bemisia tabaci (Gennadius) is one of the important soybean pests which can reduce production up to 80 %. Soybean defense mechanism against B. tabaci is affected by the physical characteristics of the leaf surface, e.g. leaf thickness, density of trichomes, and sticky glandular trichomes. The objective of this research was to investigate B. tabaci population – trichome density relationship on ten soybean varieties. The experiment was carried out in Ngale Station, Ngawi District, East Java. The tested soybean varieties were Anjasmoro, Demas 1, Dena 1, Dering 1, Devon, Detam 3, Dewah, Gema, Grayak 1, and Wilis. The experiment was done by completely randomized design with three replications. Observation on the whitefly population was conducted weekly from 2 until 10 weeks after planting on 23 sample plants in each plot. The result showed that Devon was the variety with the highest population levels of B. tabaci, 10.89 (eggs), 14.48 (nymphs) individuals per leaf, respectively. The population of B. tabaci was affected by trichomes density. Devon was the highest density of trichomes (613.7 hairs per cm2). The density of trichomes and the number of whitefly eggs and nymphs relationship were significant (R2= 0,78 (egg) and 0.84 (nymph), n= 10, ?= 1 %, F Value= 0.00157, respectively).
