Abstract

The fall armyworm Spodoptera frugiperda has spread and damaged corn in many African and a few Asian Countries recently. A recent outbreak (2019) of Spodoptera species in corn producing areas in the Island of Sumatra was suspected to be a new invasive species. Field observations were made on May 16, 2019 in the District of East and Central Lampung to identify the attacking Spodoptera species, and to observe and determine the damages. Based on the morphological characteristics, the “Y” inverted shape on the head capsule and the patterns of black spots on the abdominal segments (square and trapezoidal forms), the species was confirmed as S. frugiperda. The larvae heavily damaged the early stage of corn (approximately 2-week old) with 100% plants infested and each plant was occupied by a medium or large larva; while older corn received less damage. Larvae fed on the leaves causing defoliation before feeding on the growing point. Different damage symptoms due to S. frugiperda were compared to those of the Asian corn borer, Ostrinia furnacalis, and further discussion was made to determine the potential consequences of this new threat to the corn production in Indonesia.

Abstract

The presence of flowering plants is essential to the conservation of natural enemies in some particular ecosystems, such as agroecosystem. The objectives of this research were to determine the natural enemies associated with refugial flowering plants Zinnia elegans, Cosmos sulphureus, and Tagetes erecta planted in the rice bunts. The research took place in the rice farms in the villages of Jatisarono, Wijimulyo, and Tanjungharjo, Nanggulan Regency, Kulon Progo, District. The natural enemies were observed using three different methods: insect nets, pitfall, and direct observation. The observations were conducted in the morning, between 07.00-10.00 a.m., with an interval twice a week for 8-weeks. The natural enemies were identified to the family level. Diversity index (Shannon-Wienner), evenness index, and dominance were calculated for each plant. The diversity index for Z. elegans, C. sulphureus, and T. erecta fell in the category of medium ranging from 1.328-1.581 with medium evenness (0.365-0.574) and high dominance of 0.314-0.453. Natural enemies associated with C. sulphureus and Z. elegans were more compared to those associated with T. erecta.

Abstract

Fruit fly (Bactrocera spp.) is a global major pest species of the fruit export and import activities. The controlling and monitoring strategies based on the ecology of fruit flies were expected to overcome the problem of fruit flies. The study on the attractant compound of fruit flies from mango extract  may provide an alternative to control and to monitor fruit flies, both male or female. This research was aimed to determine the strength of attractiveness (number and type of species) and durability (day) on mango extract which could attract fruit flies. The experiment was conducted in mango plantation in Sragen Regency using Randomized Complete Block Design (RCBD) with five different locations for setting up the trap, each location consisted of nine treatments. The parameter observations were the number of trapped-fruit flies, the sex of fruit flies, the type of species fruit flies, and the durability of mango extract. The results revealed that mango extract could attract the male and female fruit flies with mechanism through the presence of nutrition and oviposition site. Extract of raw Pakel mango had a good ability to attract fruit flies, either male or female of B. carambolae and B. papaya, and male of B. albistrigata with a total of 15 flies per trap in one week.

Abstract

The study was aimed to determine the response of bacterial growth of Ralstonia solanacearum  Race  I of  biovar  III  phylotype  I  treated  with  flower  extract  of Garden Balsam (Impatiens balsamina L.) on different color of flower, that was able to give the strongest antibacterial compound and to determine the physical characteristics of I. balsamina in order to facilitate the purpose of the garden balsam cultivation as antibacterial. In addition, this study also aimed to determine the highest total anthocyanin content (TAC) and to determine the molecular characteristics of anthocyanin-coding genes and DNA base sequences of I. balsamina that indicated antibacterial properties. The research used Completely Randomized Design (CRD) 2 X 4 each with 3 replications. The first factor was the method of plating bacteria culture (pour plate and streak plate method), the second factor was the color of the garden balsam flower extracts consisted of white, red, purple and magenta. Therefore, the experiment consisted of 8 treatments of combination. Data were analyzed using CRD (α = 0.05). The results showed that the average combination of pour plate and red flower extract gave the value of resistance velocity on the 3rd day with the diameter of the inhibition zone was 33.46 mm, with the inhibitory zone diameter of the garden balsam extract of 22.90 mm. Red flower plants showed a bright red stem on the braches and the pointed leaf edge. Although this red does not show the total content of anthocyanin compounds higher than purple, however from RAPD analysis for red color indicated the anthocyanin of pelargonidin as an anthocyanin compound responsible for its antibacterial properties.

Abstract

Tomato infectious chlorosis virus (TICV) and Tomato chlorosis virus (ToCV) are members of the Crinivirus genus that induces yellowing symptoms in tomato plants. Detection of both viruses is generally carried out singly, thus it is necessary to develop a fast, accurate and efficient detection method to detect multiple viruses simultaneously in an effort to determine the suitable disease management strategies. This study was aimed to detect both viruses using the multiplex RT-PCR method and evaluate three methods of total RNA preparation used from tomato plants as RT-PCR templates. The methods evaluated were simple direct tube (SDT), simple dsRNA, and commercial kit (RNeasy Plant Mini Kit) as a comparison. The total source of RNA came from Crinivirus symptomatic tomato leaves from Kopeng, and Ketep (Central Java); Pakem (Yogyakarta); Malang (East Java); and Bogor (West Java). Single RT-PCR and multiplex RT-PCR using specific primers CPd I/CPd II and ToCV CF/ToCV CR with DNA band targets of 760 bp and 360 bp. The SDT and dsRNA methods have been successful in obtaining total RNA and viral RNA from tomato leaf samples. Total RNA RT-PCR with simple SDT and dsRNA methods followed by multiplex RT-PCR produces specific DNA band intensities that are comparable to Kit. RNA preparation with SDT and simple dsRNA methods is a simple, fast, easy and affordable method in providing templates for RT-PCR. Multiplex RT-PCR technique using two pairs of specific primers CPd I/CPd II and ToCV CF/ToCV CR is suitable for simultaneous testing of TICV and ToCV.

Abstract

Snake fruit (Salacca zalacca) is a unique fruit and it has decadent prospects to be developed as an export commodity. Nevertheless, oriental fruit fly, Bactrocera dorsalis Hendel seems to decrease the quantity and quality of this fruit. On the other side, irradiation has been developed as a standard quarantine treatment to disinfest fruit fly on fruit. The objective of this research was to determine impact of irradiation by Cobalt-60 gamma-ray on the development and survivorship of eggs and the third instar of fruitfly larvae using in-vitro and in-vivo approaches and minimum dose of Cobalt-60 gamma rays applied for snake fruit. Six doses of gamma-ray, i.e. 0 (control), 25, 50, 75, 100, 125 and 150 Gy were used in this experiment. The results showed that Cobalt-60 disturbed development and survivor rate of B. dorsalis. The development of eggs into pupa was failed when treated with Cobalt-60 at any doses, while the third instar larvae failed to become adult when irradiated with 75, 100 and 150 Gy of gamma-ray. The impacts were increased with the increment of dose. Furthermore, impact of gamma-ray irradiation was greater on eggs compared to the third instar of larvae. The minimum dose of irradiation to prevent adults emerge was 118 Gy.

Abstract

Beet armyworm (Spodoptera exigua Hübner) (Lepidoptera: Noctuidae) is known to be a polyphagous insect that infests many crops such as welsh onion, maize, tobacco, cotton, and others. In Indonesia, this species is a major pest of shallot. The study was aimed to monitor the population of beet armyworm in the shallot plantation in Bantul Regency, Yogyakarta. The monitoring was conducted using pheromone traps containing Z-9-tetra decanol 10 µg/rubber unit and Z-9-tetradecadienyl 90 µg/rubber unit. The pheromone was placed in the fields to trap males during on- and off-shallot plant season. The sites for placing the pheromone traps were selected in the farms where shallot was planted once and twice per year. The selected sites were with shallot and non-shallot in their surrounding areas. The result showed that males emerged both on- and off-shallot planting seasons in most of the areas. The average number of trapped males during the shallot season was < 5 males/trap/week. The number increased and reached the peak (7.33 males/trap/week) in June until July which was the off-shallot season. The population reduced to < 2 males/trap/week at the end of second shallot planting season until end of the year where the fields were mostly planted with rice. These findings indicate that the beet armyworm presents all year around with or without shallot in the fields. It suggests that management of this insect should be done not only during the shallot season but also the remaining seasons to obtain more effectiveness.

Abstract

Banana aphid, Pentalonia nigronervosa Coquerel (Hemiptera: Aphididae) is known as vector of Banana bunchy top virus (BBTV) that threatening production of banana worldwide. It was reported recently that P. nigronervosa and P. caladii is “cryptic species”.  A good and proper identification is necessary to verify the correct species and its status. Research was conducted to identify and to find the host range of banana aphids in Java. Aphid collection was conducted in several locations in West Java, Central Java, and East Java. Eleven morphometric characters were analyzed to assess the morphometric variations among banana aphids. Morphological identification and principle component analysis (PCA) approach were conducted for accurate identification of banana aphids. Two species of aphids were found during the survey in Java, i.e. P. nigronervosa and P. caladii. P. nigronervosa mostly infested bananas (Musa spp.), and a few was found on heliconia (Heliconia sp.) and banana traveler (Ravenala madagascariensis). In contrast, P. caladii generally infested taro (Colocasia esculenta), turmeric (Curcuma longa), costus (Costus sp.), dumbcane (Dieffenbachia sp.), but rarely on bananas.
