Abstract

Diveristy and Inhibition of Air-Borne Spores That Contaminate Substrat of OysterMushroom (Pleurotus ostreatus (Jacq. Ex Fr) Kummer). The aim of research to know thediversity, prevalence and inhibition of air-borne spores that could potentially contaminatesubtsrat baglog of oyster mushrooms. In this study using the method: (1) the arrest of sporescarried out during the hours of 7 am to 13 pm by placing three petri dish that already containsmedia PDA 3 pieces, and repeated 3 times, (2) inhibition ability of air-borne spores againstoyster mushroom. The place and time of the study conducted at Jl. Siulan Gang Zella No. 7Denpasar, and implemented in October 2014 to February 2015. The results showed that 13genera, including Aspergillus spp, as many as 10 with a prevalence of 13.51%, Aspergillusniger 7 (9.45%), Brachysporium sp., 1 (1.35%) , Cunninghamella sp. 1 (1.35 %), Fusariumspp. as many as 19 (25.6 %), Giotrichum sp. 1 (1.35%), Mucor spp. , a total of 18 (24.32%),Neurospora spp., as many as 8 (10.81%), Penicillium spp. 2 (2.70%), Phytophthora spp. 4(5.40%), Stachybotrys sp. 1 (1.35%), Trichoderma sp. 1 (1.35%) and Umbelopsis sp. 1 (1.35%). The highest prevalence achieved by Fusarium spp . amounting to 25.67 %, followed byMucor spp. 24.32%. Diversity index (H') was obtained from each replicate of 0.6438, 0.7048,0.5611 with a 0.6366 average. Dominance index (C) obtained by 0.6331. 0.8646, 0.6146, andaverage 0.7041. Diversity including < 1, marked by low diversity and dominance index closeto 1, meaning there is dominance. The dominance held by Fusarium spp . and Mucor spp.Inhibitory effects of air -borne fungi on the growth Oyster mushroom in vitro; The highestachieved by Fusarium spp, with inhibition of 94.00 ± 1.2%, followed by Aspergillus spp.amounting to 92.15 ± 1.5%, and the lowest was achieved by Penicillium spp . amounting to70.37 ± 2.5%.

Abstract

Association of Fruit Flies (Bactrocera spp.) (Diptera: Tephritidae) and Their Parasitoid on Guava (Psidium guajava L.) Cultivated in Bali. The study on the association of fruit flies (Bactrocera spp.) (Diptera: Tephritidae) and their parasitoid on guava (Psidium guajava L.) cultivated in Bali was conduted in order to know the abundance, attacks percentage and the species of parasitoid associated on guava, cultivated in Bali. The sampling was done intentionally by taking attacked fruit in Musi Village, Buleleng Regency; Pelaga Village, Badung Regency; and Tiga Village, Bangli Regency. The results showed that 3 species of fruit flies were found, namely B. carambolae, B. papayae and B. albistrigata. The percentage and number of adult insect emergence in Musi Village were B. papayae (50.87% ; 2772 imago), B. carambolae (35.18% ; 1803 imago) and B. albistrigata (13.94% ; 741 imago). In Pelaga Village B. carambolae (61.31% ; 2864 imago) dominates and B. papayae only 38.69% and 1801 imago. B. carambolae is also found dominant in Tiga Village (59.08% ; 2303 imago) and B. papayae only 40.92% and 1603 imago. Percentage of damage to guava is 24.27% on average. There are three species of parasitoids found that are associated with fruit flies on guava in Bali, namely Fopius arisanus, Diachasmimorpha sp. and Opius sp. The average parasitic rate is 6.76%. The highest parasitic rate is in Musi Village, Buleleng while the lowest is in Tiga Village, Bangli.

Abstract

The study was conducted at the Laboratory of Plant Pest and Disease Management, Departmentof Agroecotechnology, Faculty of Agriculture, University of Udayana. The purpose of this study was todetermine the life cycle of caterpillars L. marginata, praoviposisi period, oviposition, pascaoviposisi,male imago long life, female imago long life and fecundity of caterpillars L. marginata and sex ratio ofcaterpillars L. marginataThe results showed that the life cycle of L. marginata average of 52.00 ± 3.68 days with an eggstage was 8.20 ± 1.88 days, larval stage average 29.05 ± 1.76 days, and the pupal stage an average of12.60 ± 2.18 days (n = 20).The number of eggs laid by the female imago is 2872 grains with an average 143.60 ± 34.63 eggsper imago, with praoviposisi period was 2.15 ± 0.75 days, oviposition period of 1.80 ± 0.77 days, aperiod pascaoviposisi 2.05 ± 0.83 days. Females imago long live ranged from 5-7 days with an averageof 6 ± 0.85 days and males imago long life ranged from 2-7 days with an average of 4.5 ± 1.54 days(n = 20). Sex ratio of L. marginata approaching 1:1 (47% males and 53% females

Abstract

The Activity Test of Celery Leaf Extract (Apium graveolens L.) Against Bean Weevil, Callosobruchus cinensis L. (Coleoptera:Bruchidae) The experiment was conducted at the Laboratory of Plant Pest and Disease Management,Department of Agroecotechnology, Faculty of Agriculture, Udayana University. The purpose of this experiment was to examine the activity of celery leaf extract against bean weevil, Callosobruchus chinensis L. The experiment was Randomized Complete Design, with five treatments of formulation concentration. The activities of celery leaf extract was indicated through i.e. contact poison test, repellent test, and the placement of eggs (oviposition) test. The results showed that the celery leaf extract has activity as a contact poison with concentration 75% formulations caused over 50% death of the total insect. The extract with 100% concentration acted as a repellent and anti oviposition as well.

Abstract

Adaptability of Fruit Flies (Bactrocera calumniata H.) to Cucurbitaceae Host Plants in the Highlands of Bali. Plants from the Cucurbitaceae family are one of the host plants for fruit flies. Plants grow in the highlands and lowlands. One of the pests of the Cucurbitaceae family is Bactrocera calumniata. Symptoms of fruit attacked by B. calumniata are having small holes that ooze fluid caused by the puncture of the ovipositor of female fruit flies and fruit that is attacked after a long time becomes soft in texture and smells rotten. The research was conducted in Candikuning Village, Tabanan Regency and Pancasari Village, Buleleng Regency, Bali Province. Based on research showed that zucchini and cucumber were attacked by fruit flies of the type B. calumniata. Abundance of population, percentage of females, and percentage of damage were more on zucchini plants than cucumber plants. So the adaptability of the fruit fly B. calumniata is better in the zucchini plant compared to the cucumber plant.
