Abstract

Beetle activity deep inside wood was studied in field (Mt. Yoshida, Kyoto) and laboratory conditions by monitoring the type and amount of frass ejected from beetle galleries of Platypus quercivorus. Twenty-one galleries were selected from five infested Quercus serrata trees for field studies. In the laboratory, frass production was monitored for three galleries using a computer-aided electrical balance (A&D Co. Ltd.). Long-term patterns of frass production from field observation revealed that there are three distinguishable stages; a fibrous frass stage, an intermediate stage, and a powdery frass stage. The duration of the fibrous frass production was clearly different between galleries, ranging from five to twenty one days. The intermediate stage was also different from gallery to gallery, ranging from two to twenty days. Accordingly, the starting time of the third stage, powdery frass production, ranged from the 19th to the 27th day. Under laboratory conditions, the long-term patterns of frass production revealed that in galleries of logs no. 1 and 2 the fibrous frass period was stopped on the 23rd and 22nd day, respectively. Field monitoring revealed there was a negative relationship between the length of fibrous frass stage and the length of the intermediate stage.   Keywords:  fibrous frass stage,  intermediate stage, Platypus quercivorus, powdery frass stage

Abstract

Sonokembang (Pterocarpus indicus Willd.) is native of Asia trees, and commonly planted in large numbers as shade trees along roads in Malang. Research was conducted on 76 roads to identify damage intensity of dying trees on sonokembang and clarify the causal agent of dying trees in Malang from May to December 2012. Seven variables was also investigated such as characteristic of tree`s damage, distribution of holes based on sunlight exposure, vertical position of stem, and stem diameter, morphological characteristic of beetle, the intensity of dying trees, and distribution of dying trees. Results showed that there were unique damaging characteristic such as dying and then fallen leaves, holes on the stem and branches, and frass production. Euplatypus parallelus Fabricius was identified as a causal agent of dying sonokembang. There were some indications shown such as beetles preferred to attack stem side with much sunlight exposure, upper stem and medium or bigger size of stem diameter. From 3,206 trees on 76 roads, 69.7% were found dying trees. In dry and rainy season, the intensity of dying trees increased from 8.14 to 9.76% and from 10.26 to 10.79%, respectively. Keywords: Euplatypus paralellus, frass, dying trees, number of holes, sonokembang

Abstract

Parasitic Root-Lession nematode of Pratylenchus coffeae can reduce the Indonesian coffee plants productivity. Several studies reported that Pseudomonas fluorescens and Bacillus subtilis endophytic bacteria were antagonistic bacteria to nematode. The objective of this research was to reveal the effectiveness of bacterial colonies density of P. fluorescens (UB_Pf1), B.subtilis (UB BS1), and a combination of both bacteria on nematode mortality using median lethal concentration (LC50) and median lethal time 50 (LT50). The densities of bacteria used in this study were 107, 109, 1011 and 1013 cfu/ml. 35 testing nematodes were used and the mortality was counted at 6, 12, 24, 36, and 48 hours after treatments. The results showed that LC50 values of P. fluorescens was (UB_Pf1) was 4,3x108 cfu/ml, LC50 B. subtilis (UB_Bs1) was 1,9x109cfu/ ml, and LC50 combination of both bacteria was, 8x107 cfu/ml. It implies that the application of the combination of both bacteria are more pathogenic than single bacterial treatment. The results also showed that the highest LT50 value was 13.21 hours combination of bacterial colonies with a density of 1013 cfu/ml and the lowest LT50 value was 52.00 hours on P. fluorescens (UB_Pf1) treatment with colonies density of 107 cfu/ml.How to CitePurwaningtyas, P.

Abstract

Sonokembang (Pterocarpus indicus Willd.) is commonly planted as an ornamental tree in Batu city, East Java. In 2012 and 2013, there were some dying trees of sonokembang along the road of Batu city, and there were some indications that the signs and symptoms might be related to the ambrosia beetle samples from Batu. To clarify the precise condition, identification of beetle samples was needed in this research. Based on survey and  sample collections conducted in Batu from the early July 2013 to the end of March 2014, characteristic of damage on trees was observed together with the presence of beetle collected. Identification was based on morphological characters such as posterior elytral declivities and body size of male, and mycangia on female`s pronotum. Based on the morphological characters, there were some special characters which described such as 1) the body size of female adult was bigger than male adult, 2) elytral declivities on male adult was unique, and 3) there was mycangia on pronotum of female adults. Morphological char-acters showed that the ambrosia beetle attacked on sonokembang belonged to Treptoplatypus mi-crurus Schedl. This ambrosia beetle species seems to be the responsible agent that caused dying trees of sonokembang.

Abstract

Nephotettix virescens is the most effective vector for transmitting tungro disease to rice plants. Two different viral particles cause Tungro transmission. Disease control was often not anticipated in the field, especially when planting is asynchronous, that cause been detected lately. At the cellular level, vector interactions with viruses indicate vector proteins response to viral in the body of vector insects which involved in virus transmission in plants. This study aims to describe the relationship between the differentiation of N. virescens vector protein profiles on the types of tungro symptoms resulting from the transmission to develop techniques for early detection and control of the transmission process. The workflow of this study is screening on vector insects to obtain protein candidates thought to have a role in tungro transmission that had never been previously reported. The results of this study suggested that proteins with estimated molecular weights of 132, 73, and 49 kDa are candidates for proteins that can be used for screening purposes or virulent vector tracing as an early warning alternative to control tungro disease in endemic areas.

Abstract

The cucumber harvests failure occurred mainly due to the destruction of crops by the leaf-eating beetle A. similis Oliver. Many ways are taken especially pesticides that are synthesized widely because it is considered the fastest and most potent to overcome pest disorders. Based on, one of the control techniques that can be used is PGPR, which is a group of bacteria that can be utilized to strengthen plants against pest attacks and plant diseases, so research needs to be done by using this technique to change the feeding behavior of the A. similis Oliver beetle on cucumber plants. The research was conducted at the Green House Department of Pest and Plant Diseases University of Brawijaya Malang in September 2018 to March 2019. It was conducted using Randomized Block Design (RBD) 5 treatment, i.e., PGPR, urea fertilizer and control (without treatment). Based on the results of the study shows that: Application of PGPR on cucumber plant can reduce damage on either leaves or flower due to the eating behavior of imago A. similis Oliver and Application of PGPR can increase the cucumber plant growth during the eating behavior of imago A. similis Oliver.

Abstract

In an effort to reduce the impact of synthetic nematicides, a new formula was developed using plant-based nematicides that are more environmentally friendly, one of the basic ingredients that can be used is turmeric. The purpose of this study was to determine the effectiveness of turmeric extract (Curcuma domestica) with various different solvents namely aquades, methanol, and n-hexane at concentration of 5%, 10%, 15% and 20% respectively in inhibiting the activity of Meloidogyne spp. The experiment used was a Completely Randomized Design (CRD). Each treatment was repeated 4 times with 4 controls so that there were 52 experimental units. The result of different research data was analyzed using Analysis of Variance (ANOVA) which was then further tested with Honest Significant Difference (HSD) at the 5% level if real, and t-test for in vivo test. Based on the tested extract, it was found that turmeric extract with various solvent (aquades, methanol, and n-hexane) was effective in inhibiting the activity of Meloidogyne spp. nematodes outside the roots (hatching eggs and penetration), turmeric extract didn’t affect the activity of Meloidogyne spp. in the roots (development and reproduction), vegetable nematicides which the most active in suppressing the population and inhibiting the activity of nematodes was turmeric extract using methanol as a solvent at a concentration of 20%.

Abstract

Endophytic fungi have roles to protect the plant from herbivorous insects and diseases, and to support the absorption process of nutrients needed by plants for photosynthesis. Related to the important role of endophytic fungi, research was aimed to identify fungal endophytes associated with young, mature and old leaves on apple and to evaluate the effect of leaf ages on the abundance and diversity of endophytic fungi. The research was conducted in Biological Control Laboratory, Department of Plant Pests and Diseases, Faculty of Agriculture, Universitas Brawijaya from May to September 2016. Apple leaves sampling was done diagonally, and taken from nine apple trees. Based on macroscopic and microscopic characteristics, 38 isolates were identified. In the old apple leaves, it obtained 17 isolates that consisted of 5 genera, mature leaves obtained 14 isolates consisted of 6 genera, and young leaves 7 isolates obtained consists of 2 genera. The mature leaves have highest abundance and diversity of endophytic fungi compared to young and old leaves. Endophytic fungi apple leaf dominated by Aspergillus. Mature and young leaves were different from old one based on Bray-Curtis similarity.

Abstract

We examined a new method to detect the biodiversity hotspots in terms of complex patch mosaics at a regional scale in East Java, Indonesia, in order to develop the safeguard against further expansion of monocultures by REDD+. A land-cover map consisting of five major land-cover types (forest, agricultural land, bare land, water, and residential) was generated with a 30 m x 30 m resolution by the unsupervised classification of a Landsat8-OLI image. Shannon’s diversity index (H’) was calculated for each of 10.98 ha (11 x 11 pixels) landscape throughout the study area based on the dominance of the land-cover types by five calculation methods with different combinations of land-cover types. Then, the landscapes of upper 5 % in H’ was selected as the potential hotspots in terms of highly complex patch mosaics. Among the five potential hotspots, the calculation of H’ with four land-cover types (forest, agriculture, water, and bare land) was thought to be most suitable to set conservation targets at a regional scale, because the potential hotspots by this method showed aggregated distribution patterns, and was less sensitive to the small residential patches. While, no clear distribution trend was observed along the environmental gradients.
