Abstract

Blood disease bacterium (BDB) is one of the important diseases in banana and a major obstacle in developing and increasing banana production in Indonesia. The purpose of this study was to prove the ability of the Drosophilidae insect as a vector in transmitting BDB. The research was conducted at the Insect Biosystematics Laboratory and Plant Bacteriology Laboratory, Department of Plant Protection, Faculty of Agriculture, IPB University. Drosophilidae insects were taken from the field and then reared in laboratory by being fed with ripe bananas to obtain offspring that are free from diseases or pathogens. Imago of the Drosophilidae from rearing was fed by inoculum sources which was infected banana, then inoculated into healthy plants. The plants used were healthy and flowering, heliconia. The results showed that the Drosophilidae insects were able to transmit BDB to heliconia plants that showed symptoms, brownish flower colors and falling flower crowns. Detection of BDB isolated from flower parts and the inside parts of the insects used in transmission test using the PCR method showed positive results.

Abstract

Peanut pod borer caused by Etiella zinckenella is one of the important pests of peanut in Indonesia. The symptoms of E. zinckenella attack are blackened pods and rotten seeds, causing yield loss up to 90%. The research aim was to validate the efficacy of various control technology components of peanut pod borer pests. The research was conducted at the Natar (Lampung) experimental station from April to August 2014. The research was arranged using a complete randomized design (CRD) method, the treatment consisted of six control technology components, and treatment was repeated four times. The results showed that the more larvae found in the pods, the greater the damage of the pods are crushed by larvae. Application of lambda cyhalothrin insecticide (P6) starting at 35–70 days after planting (DAP) was not able to suppress larval populations of E. zinckenella so that damaged pods were also larger and not significantly different from without control (P0). Lamda sihalotrin insecticide application also harms the survival of natural enemies (predators and parasitoids). Lamda cyhalothrin insecticides can be combined with other control components such as soybean trap plants, thiametoxam and carbofuran and parasitoid of Trichogramma bactrae-bactrae to control of peanut pod borer. Application of Lecanicillium lecanii biopesticide was combined with chemical insecticides thiametoxam or carbofuran can suppress E. zinckenella larvae and yield loses, beside it can safety against the survival of predators the order Araneida and Coleoptera and parasitoid of Hymenoptera and Diptera. Biopesticides of L. lecanii were combined with tiametoxam or carbofuran insecticides can be recommended for control agents of peanut pod borer E. zinckenella.

Abstract

The potency of calabur tree (Muntingia calabura) leaf extract to control anthracnose of papaya fruit. The papaya anthracnose caused by Colletotrichum gloeosporioides is one of the factors causing a decrease in papaya production. The research aimed to determine the abilty of calabur tree leaf extract in inhibiting growth, sporulation, and viability of C. gloeosporioides as well as incubation period and disease severity on the fruit of papaya. The experiment was arranged in a nested design, the concentrations (0, 10, 20, 30, 40, 50, and 60%) were nested within the calabur tree leaf extract methods (boiling and fractionation). The results showed that boiled calabur leaves extract was more effective than fractionated calabur leaves extract to inhibit growth of C. gloeosporioides. Boiled calabur leaves extract and fractionated leaves extract at various concentration showed capability to inhibit the growth, sporulation and viability of C. gloeosporioides. Boiled calabur leaves extract at different concentration levels were able to suppress disease development of papaya anthracnose disease on papaya fruit. The higher concentration of calabur leaves extract, are more effective to inhibit C. gloeosporioides.

Abstract

Infestation of major pests and diseases on various cassava clones in Lampung-Indonesia. Lampung Province is one ofcassava producers in Indonesia which contributes more than 30% to the total national cassava production. However, theinfestation of pests and diseases can limit cassava production in the field. The objective of this research was to observe theinfestation level of major plant pests and diseases of cassava in Lampung. A survey was conducted in August 2016 in severallocations of cassava fields owned by farmers and experimental plots in the area of Faculty of Agriculture, University ofLampung. The results showed that cassava mealybug (Phenacoccus manihoti), papaya mealybug (Paracoccus marginatus)and red mite (Tetranychus urticae) infested at cassava clones in Lampung. The infestation of red mite tended to be higher thanthat of mealybugs. The cassava brown leaf spot disease that infested in mild to moderate severity was found on all cassavaclones, while viral disease with prevalence of 78% was only found on Duwet 1 clone in experimental plot.

Abstract

ysoxylum  mollissimum is a commodity that is widely used as carpentry wood and furniture in Bengkulu. Rastrococcus sp. is one of the pests of D. mollissimum. The purpose of this study was to evaluate the attack of Rastrococcus sp. on saplings, poles and trees D. mollissimum in the campus forest of Bengkulu University. The study was conducted with a purposive sampling survey method. The observational variables were symptoms and the rate of attack of Rastrococcus sp. at various stages of growth, the host range, and the identification of natural enemies of Rastrococcus sp. The results showed that Rastrococcus sp. was able to attack D. mollissimum at all growing stages, namely sapling, pole and tree. The highest number of Rastrococcus sp. population was observed in the pole phase (35.4 ± 6.46 individuals), then the tree phase (34.9 ± 20.38 individuals), and saplings (26.3 ± 5.12 individuals). The Rastrococcus sp. was commonly found in the lower leaves. Scymnus sp. (Coleoptera: Coccinellidae) and Acarina (mites) were found as predator of the mealybug. This information is expected to be a reference in developing control strategies of Rastrococcus sp. especially on D. mollissimum.

Abstract

The potency of angle measurement and comparison of vein lengths in distinguishing Bactrocera species complexes. One of the most conspicuous features of Bactrocera fruit flies is their wing, which can be elaborated for identification. The distinctive wing patterns are used to separate species and classify species complexes. The wing shape can be used as a potential discriminator between closely related taxa. To develop wing applications in taxonomy, in this study, the degree measure of angles and the comparisons of vein lengths were investigated quantitatively to distinguish among important pest quarantine species of the Bactrocera dorsalis complex: B. dorsalis and B. carambolae; the B. frauenfeldi complex: B. frauenfeldi and B. albistrigata; and a species belonging to subgenus Zeugodacus, B. cucurbitae. The result showed that species complexes were clustered into significantly different groups based on the degree measure of cell br and the comparison between r-m and dm-cu cross-vein length. This conclusive evidence was supported by phylogenetic analysis using COI gene. This present result indicated that the cell br angle measure and the comparison between r-m and dm-cu vein length could be applied to distinguish species complexes in genus Bactrocera.

Abstract

Anthracnose on red chili pepper is one of the highly damaging diseases that difficult to control bypesticides. This study aimed to determine the effect of raw secondary metabolites isolated from two isolates of Trichodermaharzianum towards anthracnose as well as the growth and yield of red chili pepper plants in the field. The research used arandomized block design with five treatments and seven replicates. The treatments tested were control, raw secondarymetabolites of T. harzianum T10 and T213, and their combination. The observed variables were incubation period, diseaseintensity, the late population density of T. harzianum, plant height, root length, fresh and dry weight of the plant and root,flowering time, number of fruits per plant, fresh weight of fruit, and phenolic compound content analysis. The result showedthat the raw secondary metabolites from the combination of the two T. harzianum isolates were the best treatments that couldlengthen the incubation period and decrease the disease intensity as 30.2 and 87.05%, respectively. However, these applicationscould not increase the growth components; while for the yield components, the application could improve the number of fruitsper plant and fresh weight of fruit as 15.33 and 34.53%, respectively.
