Abstract

Application of raw secondary metabolites from four entomopathogenic fungi against chilli disease caused by viruses. The purpose of this research was to investigate several kinds of raw secondary metabolits to decrease viral disease in chilli and inspect their side effect to plant growth. This research was conducted at experimental farm, Faculty of Agriculture, Jenderal Soedirman University from November 2018 to March 2019. The chilli seeds used for indicator plant were obtained from virus-symptomatic chilli. The raw secondary metabolites was collected from four microbial isolates used in this study, i.e. Metarhizium anisopliae, Beauveria bassiana (Papua isolate), Lecanicillium lecanii and B. bassiana Bio B10 (Jember isolate). The experiment was arranged in completely randomized design with five replications. Observation was performed on incubation period, disease intensity, AUDPC, germination percentage, plant height, number of leaves, and number of shoots. The result showed that raw secondary metabolites obtained from M. anisopliae gave the best capability to suppress disease development. Application of M. anisopliae raw secondary metabolites reduced incubation period, viral disease intensity as well as AUDPC in 34.22; 77.98 and 79.49%, respectively. The raw secondary metabolites of L. lecanii could increase percentage of germination, plant height, number of leaves, and number of shoots as 100; 38.96; 38.96 and 52.38%, respectively, compared to control.

Abstract

Impact of ecological engineering on the type and population of pests, natural enemies, and yields of the rice. This studywas performed to investigate the impact of the ecological engineering in the rice field on the crop damage caused by yellowstem borer, including it’s type and population as well as its natural enemies and the yields of the rice. The study wasconducted in farmer’s fields in Subang District in the dry and the wet seasons. The research was arranged using RandomizedComplete Block Design (RCBD) with 9 treatments and 3 replications. The observation was conducted on the crop damagecaused by yellow stem borer, the type and the population of pests insect, its predator, and parasitoid as well as yields of therice. The planting of flowering plants and crops showed inconsistent effect on the population of brown planthoppers, whitebacked planthoppers, and rice black bug. Moreover, it also not significantly impact the yellow stem borer. The planting offlowering plants and crops did not affect the rice yields. The parasitization level of the parasitoid was in ranged of 47.32–50.47% (dry season) and 36.37–53.92% (wet season). The neutral insect population was dominant at the beginning of planting(11–1743), meanwhile at the maximum tillering until the harvest was dominated by predators (9.33–131.33). The parasitoidswere relatively contrasted on each stage of the rice plant.

Abstract

Utilization of betel leaves extract to prevent the growth of Fusarium oxysporum f.sp. capsici causing fusarium wilt diseasein bell pepper. Betel (Piper betle Linn.) is commonly used in Indonesian traditional medicine due to its antimicrobial properties,thus it is often used as an ingredient in natural pesticides. The effectiveness of betel leaf extract as a control for Fusariumoxysporum in several plants showed it’s potential to control the fungi in bell pepper. F. oxysporum f.sp. capsici is one of theimportant pathogens causing Fusarium wilt disease in bell pepper. It is one of the most devastating plant diseases due to itsability to cause a crop failure. The test on the inhibitory capacity of betel leaf extract on the growth of F. oxysporum f.sp.capsici were carried out by growing the fungi on PDA mixed with various concentrations of betel leaf extracts. The resultsshowed that betel leaf extract treatment at 0.02% concentration was able to inhibit the growth of F. oxysporum f.sp. capsici inPDA at 95.54%. The full inhibition of colony growth (100%) was achieved in the extract treated with the concentration of0.03%. Meanwhile treatment of 0.17% betel leaf extract was able to inhibit the growth of F. oxysporum f.sp. capsici on bellpepper stems. Following this result, fractionation of the betel leaf extract by column chromatography was conducted, resultingin 44 fractions. The bioassays of those fractions showed that, there were seven fractions that reveal inhibition capabilityagainst F. oxysporum f.sp. capsici.

Abstract

Fluctuation of Doleschallia bisaltide larvae (Lepidoptera: Nymphalidae) on caricature-plant (Graptophyllum pictum). Caricature-plant cultivation is often damaged due to the attack of Doleschallia bisaltide larvae. High reproduction ability of D. bisaltide is a serious problem that need to be managed, therefore it will not inflict a financial losses. This study was aimed to determine the fluctuation of D. bisaltide larval population in the caricature-plant plantation in Kalisoro, Tawangmangu. The observations were carried out with a survey method on five observation plots for seven months from March to September 2018. The data were analyzed by descriptive statistics and the Spearman rank correlation coefficient test. The results showed that the population structure was changed during the observations with the highest larval population in May. The results of Spearman rank correlation coefficient test showed significant and positive correlation between third, fourth, and fifth instars larvae with the rainfall. The control of D. bisaltide can not only depend on the presence of natural enemies, therefore control interventions were needed especially at a suitable time and environment whne the population increased.

Abstract

Resistance evaluation of modern rice varieties to brown planthopper Nilaparvata lugens STÃ…L. The research was performedto understand the resistance of modern rice varieties to the field population of brown planthopper (BPH). The researchstudied BPH settling preference, numbers of laid eggs, and functional plant loss index (FPLI) of resistant and susceptible ricevarieties. The results showed BPH were less settle and laid fewer eggs on resistant varieties. BPH significantly settled longeron TN1 than other varieties after 24 hours. The numbers of eggs laid on rice resistant varieties (Inpari 13, Inpari 31, Inpari 33,RH, and PTB33) were fewer compared to TN1. FPLI value in TN1 was the highest among the tested rice varieties. Inpari 13 hadbetter resistance to BPH compared to Inpari 31 and Inpari 33. In managing BPH in endemic areas, we recommend Inpari 13,Inpari 31, and Inpari 33 to be planted in rotation.

Abstract

Development of pink disease on the various ages of Acacia crassicarpa Cunn Ex. Benth.. The increase in the value of pulpand paper exports in Indonesia is partly due to the development of industrial forest plantations of acacia on peatlands. Acaciacrassicarpa grows well on peatlands with high productivity. However, the development of pink disease is a threat to thegrowth of A. crassicarpa, both in the nursery and in the field. This study aimed at examining the development of pink diseaseon the various ages of A. crassicarpa. The study was conducted using census method on plants at aged 4, 24 and 42 months.Variables observed were symptoms, incidence, and severity of disease. Data were analyzed descriptively and regressively tounderstand the relationship between the incidence and severity of the disease and the age of the plant. The results showedthat the symptoms that appearing at the seedling level were similar to those the sapling, poles and tree level. The presence ofthin colonies of cobweb-like (cobweb stage), mycelia aggregation from the cobweb stage (pseudonodular stage), and theappearance of pustules and pink incrustation (teleomorph stage) were common symptom. However, disease incidence andseverity were moderate at the seedling and mild at the saplings, poles and trees level. The incidence and severity of diseasedecreased with increasing age.

Abstract

Influence of host stage on oviposition, development, and sex ratio of Anagyrus lopezi (De Santis) (Hymenoptera: Encyrtidae),a parasitoid of the cassava mealybug, Phenacoccus manihoti Matile-Ferrero (Hemiptera: Pseudococcidae). The parasitoidAnagyrus lopezi (De Santis) (Hymenoptera: Encyrtidae) was introduced from Thailand into Indonesia in early 2014 to controlthe invasive cassava mealybug, Phenacoccus manihoti Matile-Ferrero (Hemiptera: Pseudococcidae). Because of the need toproduce large numbers of high-quality females, research was conducted in the laboratory to determine host stage preferencefor A. lopezi on different instars of P. manihoti. Individual female wasps were exposed to first, second, third instar nymphs,and pre-reproductive adult mealybugs. In the no-choice test, the frequency of parasitized hosts and the number of eggs laidper host was significantly higher in second and third instar nymphs as well as adult mealybugs compared to first instarnymphs. In the two-choice test, third instars nymphs and adult mealybugs were the most preferred host for oviposition.Immature development of parasitoids was faster and the ratio of female to male parasitoids was higher following ovipositionin second and third instar nymphs and pre-reproductive adult hosts, compared to the first instar nymphs. Our findingsindicate that the use of pre-reproductive adults as hosts in a mass-rearing program would be the most productive and fastestway to produce A. lopezi populations with a female-biased sex ratio. Field release of parasitoids should be conducted whenthe host’s third instar nymph is the most abundant because the period during which preferred and suitable host stages areavailable would be the longest.

Abstract

Utilization of plant extracts to suppress Squash Mosaic Virus Infection on ridged gourd (Luffa acutangula [L]. Roxb).Control effort strategies against plant pathogens are necessary to be explored and evaluated its effectiveness intensively.One environmentally friendly control method is biological control by using plant extracts. It is well known that cucurbits arecultivated widely in Indonesia. However, cucurbits are susceptible plants against various pathogens, including viruses.Recently, Squash mosaic virus (SqMV) found to infect cucurbits such as ridged gourd in West Java. The research aimed toexplore and evaluate the effectiveness of plant extracts to suppress SqMV infection on the ridged gourd. Three selectedplants, namely Bougainvillea spectabilis, Mirabilis jalapa, and Celosia cristata, were tested in greenhouse trial with aspirinas a comparison. The extract was sprayed on the leaves a day before mechanical virus infection. The disease assessments andagronomic parameters were observed. The plant extract treatment showed able to prolonged the incubation period, causedmilder symptoms, reduced the virus titer, and showed better plant growth in compared with aspirin treatment or untreatedcontrol. B. spectabilis and M. jalapa crude leaf extract revealed able to suppress the SqMV infection with comparableeffectiveness with relative inhibition level of disease severity and virus titer up to 48.2% and 80.6 to 81.4%, respectively,indicating their potential as biocontrol for SqMV.
