Paddy Rice Stemborer Attact and The Role of Parasitoid in Control That Population atSimultaneous and Stagered Ricefield. The arrangement of suistable agriculture in Baliwhich appropriate with Bali governments mission : Bali Clean and Green Go to Organic. Theconcept of modern agriculture look like contradiction with the aspects suistainableagriculture. The aspect of cultivation have been done by local agriculture community in Balicall it Subak for many years, but the attack of yellow rice borer still happen, wich adversefarmers side, persist. The efforts control wich has been done, still rely on pesticides, becauseit can give quick effect, but it is not appropriate for suistainable agriculture. The othersolution to solve that issues with the integrated pest management (IPM) as the maincomponent of with is the role parasitoids. The experiment was carried out at simultaneousplanting area (Subak Sidakarya, Denpasar Selatan District) and at staggered planting area(Subak Buaji, Denpasar Timur District). The result of this experiment showed that damageintensity of rice stemborer at simmultaneus planting was lower than at staggered plantingarea. There are four species stemborer at simultaneous planting area and at staggered plantingareas, namely Scirpophaga incertulas, Sesamia inferens, Chilo suppressalis, and Chilopolychrysus. Three kinds of egg parasitoids were found to decrease the population of ricedstemborer. They were Tetrastichus schoenobii, Telenomus rowani and Trichogrammajaponicum.

Predation and Functional Response Test of Predator Chysoperla carnea Stephens (Neuroptera: Crysopidae) Against Phenacoccus manihoti Matile-Ferrero (Hemiptera: Pseudococcidae). This study aims to evaluate the predatory capacity of C. carnea by measuring the rate of searching capacity and handling-time of one prey and its functional response to the population density of P. manihoti. The research was conducted at the Integrated Pest Management Laboratory (IPMLab), Faculty of Agriculture, Udayana University. The study was conducted from February to May 2019. Testing of functional responses used a randomized block design with 5 treatments (3, 6, 9, 12, 15 nymphs-3) each of which was repeated 10 times. The results showed that the prey searching-capacity when the population was low (3 nymphs-3) took longer (10.37 minutes), while when the population was high it took a short time (6.23 minutes). The length of time for handling one prey in the low population was 6.08 minutes, while in the high population it was 5.48 minutes. Predator C. carnea has a tpe-2 functional response to an increase in the population of P. manihoti nymphs with the equation Y = 4.32x / 1 + 1.973x (R2 = 0.980). The rate of predation increases sharply when the population of low increases, and decreases when the increase of prey population increases. C. carnea has the potential to be developed as a control agent for P. manihoti.

Abstract: The use of medicinal plants to maintain or overcome health problems has long been carried out by worldwide community. Along with the development of knowledge, data about the existence of undesirable effects or side effects associated with the use of medicinal plants that are not appropriate are obtained. This research is conducted to determine public knowledge about the safety several medicinal plants use. The study was conducted with a questionnaire technique in Lombok Praya, Indonesia. The results show that knowledge about the safety of the use of medicinal plants in breastfeeding mothers obtains the correct answer by 48%, knowledge about the parts of medicinal plants that are dangerous for consumption by 39% and knowledge about medicinal plants that can increase health risks by 21%. Whereas, the knowledges for the use of medicinal plants in pregnant women and the use of medicinal plants that are not right obtains very good results with correct answers of 79% and 81%. Based on further interviews, these good results are obtained because they are supported more by traditional use of the plant that has already existed in the area. Public understanding of the safety of some medicinal plants in Lombok Praya is still lacking. It is necessary to add knowledge about the use of medicinal plants that requires special attention, especially on plants that are often used by people in the area. Local health agencies need to disseminate information on the safety of medicinal plants that is wider and more sustainable. Keywords: Community, medicinal plant, safety, public understanding.

The research was conducted in the field of Taro village Gianyar regency and Katung village Bangli regency and at the Laboratory of Biotechnology Faculty of Agricultural Udayana University. The purpose of the research were to investigate population dynamic of Diaphorina citri Kuwayama and other insects that were assosiated with citrus cv. siam; and molecular detection of CVPD patogen in its vector, other phytophagous insects on citrus cv.siam and kemuning [Murraya paniculata (L.) Jack.] The result of this study showed that in six month period there was one peak of D. citri population which was associated with the flushing period of citrus at Taro as well Katung villages. The peak of D. citri population of Taro village was higher than that of Katung village. Two species of parasitoids and four spesies of predators were found in the field and may contribute in the suppression of D. citri population. The parasitoids identified were Tamarixia radiata Wat. and Diaphorencyrtus alligharensi Shaffe, whereas the predators were Curinus coeruleus Mulsant, Phiddipus sp., Menochilus sexmaculatus Fabricius and Oxyopes javanus Thorell. T. radiata has been proven to be an effective nymph parasitoid that could suppress the population development of D. citri in citrus orchads. The research revealed that kemuning could serve as a source of infection because it is also a host of CVPD disease as well as of D. citri. Toxoptera citricidus Kirkaldy and Maleuterpes dentipes Hell. were not proven to contain CVPD disease.

Civet (Paradoxurus hermaphroditus) are carnivorous animals, but also often eat fruit and one of them is coffee cherries. The coffee cherries that are eaten are not completely digested, so the coffee beans come out with the civet feces. In the civet digestion there are various kinds of bacteria that help the digestive process, one of them is cellulolytic bacteria. It is possible that coffee beans in civet feces contain cellulolytic bacteria.This study aims to determine the presence of cellulolytic bacteria in civet feces. The results of bacterial isolation in civet feces obtained 6 isolates that had different morphological characters. Cellulolytic bacteria screening results showed that 2 out of 6 isolates were positive as cellulolytic bacteria, namely FL2 isolate with a cellulolytic index of 2.38 (high reaction) and FL3 isolate with a cellulolytic index of 1.24 (medium reaction). The isolates FL2 and FL3 had different morphological characters in colony shape, margins and color, but had similarities in elevation, gram color and cell shape.
