Abstract

Effectiveness of botanical insecticide formulations against cocoa pod borer Conopomorpha cramerella (Snell.). Cocoa pod borer (CPB), Conopomorpha cramerella (Lepidoptera: Gracillariidae), is a major pest on cocoa plants. The research aimed atfinding out botanical insecticide formulations that are effective against CPB. Plant materials used for preparing the formulations were cashew nut shell (Anacardium occidentale), whiteflower albizia (Albizia saponari), siam weed (Chromolaena odorata), and candle bush (Senna alata) extract. This research was conducted in the field using a randomized complete block design with the following treatments: formulation of cashew nut shell extract, cashew nut shell extract + whiteflower albizia bark extract, cashew nut shell extract + siam weed leaf extract, cashew nut shell extract + candle bush leaf extract, cashew nut shell extract + whiteflower albizia bark extract + siam weed leaf extract + candle bush leaf extract, and a synthetic insecticide formulation containing a mixture of lambda-cyhalotrin 106 g/L and thiametoxam 141 g/L as well as control (without botanical and synthetic insecticide treatment). The concentration of botanical pesticides applied from cashew nut shell extract used was 2.5 mL/L, while from other ingredients 250 mL/L.Variables observed were intensity of CPB infestation, degree of damage to the cocoa seed, and the efficacy of botanical insecticide treatments. The results showed that the test botanical insecticide formulations reduced the intensity of CPB infestation by 48.9?55.3% and the degree of seed damage by 52.3?58.2% compared with control. The efficacy of the test botanical insecticide formulations in controlling CPB was relatively the same when compared to each other, with a range of efficacy of 64.2?71.0%, but was lower than that of the synthetic insecticide formulation (92.8% efficacy). The implication of this research is that botanical insecticide formulations have the prospect of being continuously developed and have the potential to reduce the used of synthetic insecticides.

Abstract

Termites are social insects that play an important role in ecosystem. Habitat is a crucial factors determining diversity of termites. IPB University campus has quite diverse habitat types. In this research, we study the diversity and abundance of termite species around IPB University campus. Two methods used for data collection, i.e. baiting system with pine wood and transect survey within 10 x 10 m area. Six species of termites found belongs to two families, Termitidae (Macrotermes gilvus, Odontotermes javanicus, Microtermes insperatus, and Capritermes mohri) and Rhinotermitidae (Schedorhinotermes javanicus and Coptotermes curvignathus). The most diverse with the high abundance of these termites are found in the  rubber trees area, Faculty of Fisheries (FPI) and the forest behind the main administration building, Rectorate (REK) because this area provides an abundant source of cellulose as a food source for termites. While the building areas tend to have a lower diversity and abundance index because food sources for termites are not always available due to human activities. Non-metric multidimensional scaling analysis shows that the termites species composition is different between study area.

Abstract

Antiviral Activity of Cashew Nut Shell Extract Against Cowpea mild mottle virus on Soybean. Cowpea mild mottle virus (CPMMV) is one of important virus on soybean. Management of CPMMV is usually by controlling its vector using insecticide which has adverse effect on environmental and non target insect. Therefore, it is important to find an alternative control which is environment friendly such as utilizing of plant extract. Cashew nut shell (CNS) is a waste during processing of cashew nut and reported containing some antimicrobe substances.  The research was aimed to evaluated the potency of CNS extract as antiviral against CPMMV. The experiment was designed by Randomized Block Design with 4 replicates and each treatment unit consisted of 10 plants. The application method (prior and post virus inoculation, mixing of virus sap and CNS extract) and concentration of CNS extract (0.75 %; 1.5 %; 3.0 %; 6.0 %) were evaluated the effectiveness of their combination to inhibit CPMMV infection. The application of CNS extract were abled to decreased disease incidence and increase incubation period compared  to untreated with CNS extract. and severity of treated plants significantly. However, plants treated with concentration 3.0 %  and 6.0 % prior virus inoculation and mixing CNS extract with concentration 1.5 %, 3.0 %, and 6.0 % with CPMMV sap showed that the virus titre was negatively detected by ELISA using CPMMV antisera.  It is indicated that the potential of CNS extract as antiviral. All treatments combination able to suppress virus infection without phytotoxicity effect, except CNS 6.0 % treatment.

Abstract

Effect of application of abamectine on the abudance of leafminer flies and its parasitoids on potato fields. The objective of research was to investigate the effect of the application of abamectine insecticide on the infestation of potato leafminer and its parasitoid. The fields experiment was conducted on potato fields in Pangalengan ? Bandung, West Java in 2000. The result showed that the abamectine-insecticide significantly reduce the plant damage intensities, the number of mining per plants, and the percentage of leaf damage. In addition, the application of abamectine insecticide was not significantly affected the level of parasitism and the number of parasitoid Hemiptarsenus varicornis (Girault) (Hymenoptera:Eulophidae) and Opius sp. (Hymenoptera: Braconidae) that were emerged from leaf sample. The abamectine insecticide has a good possibilities to be used as an alternative for controlling of the leafminers before another technology was found.

Abstract

Polytomous Quantal Response of Crocidolomia pavonana (F.) (Lepidoptera: Pyralidae) to Extracts of Aglaia spp. and Dysoxylum spp. (Meliaceae).  This work was done to study the polytomous binary response of the cabbage head caterpillar Crocidolomia pavonana (F.) to extracts of two species each of Aglaia and Dysoxylum (Meliaceae). Second-instar larvae C. pavonana were fed extract-treated broccoli leaves for 2 days and then the surviving larvae were maintained on untreated leaves until pupation.  Relationship between extract concentration and the number of dead larvae in different instars was analyzed using polytomous quantal response analysis based on the conditional logit model.  The results showed that twig extract of Dysoxylum acutangulum and seed extract of D. mollissimum possessed strong insect growth regulating activity against C. pavonana larvae as reflected by highly significant responses in the later insect life stages after the feeding treatment was removed, including the significant occurrence of malformed pupae. On the contrary, the feeding treatment with twig extract of Aglaia odorata and seed extract of A. odoratissima resulted in highly significant responses only in the treated larval instar, and after the feeding treatment was removed, responses in the later life stages were insignificant or much less significant. Overall, the above results suggest that Dysoxylum extracts interfered with hormonally-controlled insect development and metamorphosis, whereas the activity of Aglaia extracts was more insecticidal rather than insect growth regulating.

Abstract

Blood disease is one of the important diseases of banana in Indonesia. Endophytic bacteria have potencies as candidates of biocontrol agents to blood disease, because the bacteria colonized the same ecological niche with the plant pathogens. This research was conducted to isolate endophytic bacteria from banana root, and study their disease suppression ability to blood disease on banana. Ninety isolates of endophytic bacteria have been isolated from the root of banana. Average population densities of bacteria varied between 6,0 x 103 and 4,2 x 105 cfu/g fresh weight of root. Twenty seven isolates positively produced inhibition zone toward blood disease bacterium. Based on plant growth and disease suppression test, ten isolates promoted the growth of banana plant and four isolates suppressed the incidence of blood disease with ranged from 66,67 to 83,33%.

Abstract

ABSTRACTPineapple fruit collapse: newly emerging disease of pineapple fruit in Lampung, Indonesia Recently, a new disease on pineapple fruit has occurred in Lampung. Symptoms of the disease are complex. Fruits rotted and exuded copious liquid from the inter- fruitlet tissues accompanied by gas bubbles. Open spaces were formed inside the rotten fruit. Dissection of diseased fruit showed many cavities within its sceletal fibres and bad odour was exerted from the rotten tissues. A bacterial entity was isolated  from the diseased materials. In a pathogenicity test, the isolated bacteria caused the same symptom as mentioned. In the growing-on test the crown of the heavily infected fruit  showed  heart rot symptom.  Those  indicated that the disease was pineapple fruit collapse. Both symptoms were known related to the same causal agent, Erwinia chrysanthemi (pineapple strain Dickeya sp.). In our opinion, this is the first report of pineapple fruit collapse in Indonesia.
