Abstract

ABSTRACT Efficacy of Essential Oils Extracted from Tropical Plants to Hairy Caterpillar Efficacy of some essential oils extracted from tropical plant to hairy caterpillar was conducted in order to find out the method to control population of hairy caterpillar which were increased drastically in 2010 to 2011 in Indonesia. The insect were reported to attack some plants such as: wooden plants; horticulture crops, especially, mango trees and some ornamental plants. Although, these caterpillar have not been found to attack food crops. These insects arising some problems: scared as well as skin etches, etc., especially when these insects entering the communities residence. To control the caterpillar, recently, peoples used chemical insecticide, however the impact of chemicals insecticide is dangerous to human being, livestock, and environmental. Therefore to minimizing those problems, the control methods should be environmental-friendly and safe against human being. One of those methods is utilizing the botanical pesticide which is extracted from tropical plants. Three of topical plants such as: citronellagrass (Cymbopogon nardus), lemongrass (Cymbopogon citratus), neem (Azadirachta indica), were done in this experiment to utilize it as botanical pesticide. The experiment result shown at the concentration 10%, all of the essential oils are effective to kill the caterpillar (90-100%). Therefore the examinations of low concentrations of essential oils were conducted (5, 2, and 1%). The result of 1% concentration of lemongrass was found most effective to kill caterpillar (98%). The examinations for lemongrass under 1% concentration (0.75, 0.50, and 0.25%) were continued. From those examinations, under concentration of 0.50 % the caterpillar was killed 90%, while the concentration of 0.25% was not effective (50%). Keywords: hairy caterpillar, essential oil

Abstract

Identification of Bacteria Causing the Main Diseases in Hydroponic Plants Hydroponics is a horticultural cultivation technique using water as its growing medium. As the times progressed, people began to switch to planting with a hydroponic system, but this system was not completely free from pathogen attacks, one of which was bacteria. Therefore, this study aims to identify the types of bacteria that can infect hydroponic plants and determine the percentage of disease in hydroponic plants. The research implementation includes (1) calculating the percentage of disease, (2) sampling, (3) symptomatic plant isolation, (4) inoculation, (5) morphological classification, (6) detection of bacteria by PCR (Polymerase Chain Reaction), and sequencing analysis. The results showed that the percentage of attack on three plants, namely lettuce with soft rot symptoms, was 31.6% and celery with bacterial blight symptoms was 56.1%. The highest attack percentage was on tomato plants with bacterial wilt symptoms, reaching 69.1%. PCR results showed DNA bands measuring ± 1500 bp using general 16S rRNA primers (27F forward and 1492R reverse) on the three plants. Sequence analysis was continued on bacterial isolates from tomato plants because they had the highest percentage of attack. The nucleotide analysis of bacterial isolates in tomato plants indicated that the bacteria were a genus of Pseudomonas sp. Homology level of Pseudomonas sp. from Kesiman Village, East Denpasar District, Bali, after being traced and matched to the GenBank data in the NCBI program, it has similar homology with Pseudomonas from Iraq and India with a homology level of 89.86%, as well as from Egypt, New Zealand, and Germany with a sequence homology level of 89.19%.

Abstract

Utilization of Insect Pathogen (Beauveria bassiana Bals.) to Control the Suction Pest of Cocoa (Helopeltis spp.) in Gadungan Village,The District of East Selemadeg, Tabanan RegencyCultivation of cocoa has the potential to improve the economy of farmers. However, cocoa production has decreased due to Helopeltis spp. The control of Helopeltis spp. still use synthetic chemical pesticides that are harmful to the health of farmers, consumers and environmental pollution. Therefore, it needs to be done by eco-friendly control using Beauveria bassiana which is reported to be able to control some insect pests such as Helopeltis spp. Utilization of B. bassiana is usually in the form of formulations. The research was conducted to determine the quality formulations and efficacy of B. bassiana against Helopeltis spp. obtained from Dinas Perkebunan Provinsi Bali. The research method using randomized block design with 5 treatments, 5 replications and the treatment using concentration formulation 20 grams, 15 grams, 10 grams, 5 grams to dissolve in one liter of water and the control just using water. The observed variable is the number of former suction on fruit. The identification results showed the tested formulations made from active B. bassiana which is characterized by colonies are white, round-shape and the spore structure is like grapes with a good quality because it has spore density 1,06x107 spore/ ml. B. bassiana is quite effective to infect Helopeltis spp. because it just need 4 days to kill Helopeltis spp. The test results showed the concentration of 20 grams formulation is the best concentration with the fewest number of former suction on fruit.

Abstract

ABSTRACT Monitoring of Imago of Spodoptera litura and Helicoverpa armigera Using Sex Pheromone Trap The utilization of sex pheromone to control insect pest is one of advance technology. The sex pheromone is one method to control insect pests for support food security. In other to know the ability of sex pheromone to trap insect the monitoring of insect using sex pheromone is needed. The lure of sex pheromone, glue, and box trap were imported from AVRDC-The World Vegetable Center. Sex pheromone trap is putted on the vegetable area in Bali, the locations including Sandan, Kembang Merta, Candi Kuning (Tabanan Regence) and Pancasari (Buleleng Regence). On each location trap was placed with two replications. Data collection was conducted every week, on 3rd week observation the imago/moth population is completely reduce. Therefore the trap was replaced for the new trap. That mean the observation was conducted 3 times per experiment (Observation 1,2,3). In this case the experiments were done 2 times (Experiment 1 and 2). The identification of imago was base on the morphological method. The imago was accounted for data collection. The decrease of population of Spodoptera litura and Helicoverpa armigera after 3 week observation is possible caused by the ability of pheromone active ingredient is also decrease. The distribution of imago S. litura and H. armigera are same for all locations. However the total population of S. litura and H. armigera is different. The population of S. litura was very high in all locations around 51-107. However the population of H. armigera was generally low except in Sandan Tabanan (70). In Pacasari the population of H. armigera was lowest around 14-15. The differentiation of imago S. litura and H. armigera were possible influenced by the host plant, altitude and also climate conditions. Key worlds: sex pheromone, Spodotera litura, Helicoverpa armigira
