Abstract

Diversity of parasitic Hymenoptera in different ecosystem types in Central Bangka, Bangka-Belitung Islands.Hymenoptera richness is dominated by parasitic species. More than 80% of Hymenoptera play a role as parasitoid on arthropods that are mostly insects. Diversity of parasitic Hymenoptera is widely studied in various types of terrestrial ecosystems including agro-ecosystem and non-agro-ecosystem. This study aimed to invent and compare the diversity of parasitic Hymenoptera in three different ecosystems, i.e., forest, oil palm plantation, and ex-tin mining. The location was located in Central Bangka Regency, Bangka Island. The study was conducted in Juli 2014 until October 2015. Parasitic Hymenoptera was collected with insect sweep net and yellow pan trap on one transect line with 1000 m length. Parasitic Hymenoptera were found on forest as much as 732 morphospecies, 326 morphospecies on oil palm plantations, and 293 morphospecies on ex-tin mining. Diversity and abundance of parasitic Hymenoptera on forest was higher than oil palm plantation and ex-tin mining area. Braconidae family was found dominant on forest, however on oil palm plantation and extin mining area the dominant family was Scelionidae.

Abstract

Comparing application methods of entomopathogenic fungus Beauveria bassiana to control Cylas formicarius (Coleoptera: Curculionidae). Cylas formicarius is a major pest of sweet potatoes. The tuber damage caused by C. formicarius reaches 100%. The research objective was to compare application methods of entomopathogenic fungi Beauveria bassiana to control C. formicarius. The research was conducted at the entomology screen house of Indonesian Legume and Tuber Crops Research Institute (ILETRI) at Malang, East Java, from January to September 2013. The treatment consisted of 12 application methods, each was repeated three times. The results showed that application of B. bassiana into the planting pit, soaking the sweet potato cuttings into the conidial suspension of B. bassiana for 30 minutes before planting, followed by spray application with two week interval (2 to 12 weeks after planting, WAP) or P4 was effective in suppressing C. formicarius population and tuber damage. Tuber weight obtained from P4 treatment was 1.4 kg plant-1, while from the chemical insecticide was only 1.1 kg plant-1. Tuber damage from P4 treatment was lower ( 5%) than that from chemical insecticide treatment (42%). Therefore, application of B. bassiana conidial suspension in the planting pit, continued by soaking the sweet potato cuttinginto the B. bassiana conidial suspension for 30 minutes before planting, and followed by spray applications of B. bassiana conidial suspension at two-week intervals ( 2-12 WAP) or P4 method can be recommended to control C. formicarius.

Abstract

Effect of pest management systems to the insect pests population on Anjasmoro and Wilis soybean varieties. The integrated pest management (IPM) is a pest control approach which is based on ecological and economic considerations. The objective of this research was to study the effect of different pest management systems on the insect pest population using two soybean varieties, Anjasmoro and Wilis.The experiments were done in a randomized complete block design, repeated twice. The pest management systems under the different plots were integrated pest management, non-chemical control, chemical control, and the control (which received neither chemicals nor IPM). Observations were made on the pest population and the intensity of the damage caused by primary soybean pests. The primary pests observed were Ophiomya phaseoli, Aphis gossypii, Lamprosema indicata, Spodoptera litura, Bemisia tabaci, Riptortus linearis and Etiella zinckenella. Integrated pest management significantly affect the population of whitefly on Anjasmoro variety but not on Wilis variety. The populations of bean fly, aphid, leaf roller, armyworm, stink bug and pod borer were not affected by pest management system. The lower yield of Anjasmoro variety was attributed to the attack by a viral infection whose disease incidence reached 80% on the plots without a pest management system. IPM management system was more efficient than chemical management system.

Abstract

Solid formulations of indigenous rhizobacteria Bacillus thuringiensis TS2 and storage time to control bacterial pustule disease Xanthomonas axonopodis pv. glycines. Bacterial pustule disease caused by Xanthomonas axonopodis pv. Glycines is a major constraint in soybean cultivation. Indigenous rhizobacteria Bacillus thuringiensis TS2 from soybean rhizosphere acquired from previous research is the best isolate which can control soybean bacterial pustule disease and increase growth rate of soybean. To increased its stability and interaction with soybean plants, Bacillus thuringiensis TS2 was urged to test furthermore especially its formulation with based formula tapioca powder, peat and bulk. The most effective storage time also need to test. Result showed that all rhizobacterial formula had ability to decrease incidence of bacterial pustule disease compared to control. Moreover, all the three formula could increase plant growth, total of leaves, total of branch and yields. Flowering time was also advanced by 1-8 days compared to control. Decreasing of disease rate and increasing of plant growth rate variated between different formulations.

Abstract

Efficacy of selected Trichoderma isolate and organic matter to control foot rot of black pepper in the field. The objective of this experiment was to determine the efficacy of selected Trichoderma isolatand organic matter to control the disease. Dual culture method was used to select a Trichoderma isolate. The experiment to evaluate the efficacy of selected isolate consisted of control (no application of T. harzianum or organic matter), T. harzianum and rice straw, and T. harzianum and coffee husk. As starter, T. harzianum was grown in broken rice. Two liters of organic matter was infested with suspension of 10 g starter in 100 ml steril water and incubated for 2 weeks. The mixture was applied around the base of black pepper stem. The results showed that all plants treated with T. harzianum and organic matter did not show disease symptom. Ten percent of the control plants showed symptoms. However, statistical analysis showed that the occurrence of the disease was not significantly different between treatments. Applications ofT. harzianum and rice straw increased the density of Trichoderma for 1 and 2 months after application. T. harzianum and coffee husk increased the density of the fungus 1 month after application.

Abstract

Lepidopteran community and its parasitoid on cucumber field in Bogor, Sukabumi and Cianjur District, West Java. Cucumber is one of horticultural commodities that are widely cultivated in Indonesia, but information related to Lepidoptera pests and their parasitoids are limited. The aim of this study was to obtain information about Lepidopteran community on cucumber and their parasitoid diversity. Lepidopteran larvae were collected from 16 cucumber sites in the District of Bogor, Sukabumi and Cianjur in November 2014 until May 2015. Larvae were collected from each cucumber plant follow along 60 m transects. Larvae were collected from the field then brought to the laboratory. All larvae were then reared on cucumber leaves until pupation and parasitoids emerged. The data obtained were tested by analysis of the mean and analysis of variance (One way ANOVA) using the program R Stat. The results showed that cucumber plants were attacked by six species (morphospecies) belonging to four families of Lepidoptera. Diaphania indica (Saunders) (Lepidoptera: Crambidae) is the most abundant species found. All species (morphospecies) of Lepidoptera are more common when the cucumber plants are in the generative growth stage. Our result further showed that D. indica was attacked by 9 parasitoid larvae and 3 parasitoid pupae, C. chalcites (Lepidoptera: Noctuidae) by 5 parasitoids dan S. litura (Lepidoptera: Noctuidae) by 2 parasitoids. A braconid, Apanteles taragamae, is the most common parasitoid of D. indica found in the field. Its parasitism rate can reach 27% in the field. Overall, this research revealed that a number of parasitoids, that were found attacking Lepidopteran on cucumber indicates their potential use as biological control agents in this agroecosystems.

Abstract

Persistence of several antagonistic fungus on chilli and its potential to suppress anthracnose disease caused by Colletotrichum gloeosporioides. Anthracnose disease caused by C. gloeosporioides is one of the important diseases on chilli because its directly gives negative impact on chilli production. The aim of this research was to obtain the superior antagonistic fungi that have ability to persist on chili fruit and potential to control anthracnose disease caused by C. gloeosporioides  The experiment consist of two units: 1. Testing of persistence ability of antagonistic fungi on chilli fruit, 2. Testing the potential of antagonistic fungi to suppress anthracnose disease on chilli fruit. Both of the test used Randomized Block Design (RBD) with 10 treatments and 4 replication, each of replication consist of 4 chilies fruit. Those treatments were Trichoderma-PP1, Trichoderma-PP3, Trichoderma-AG2, Trichoderma-PYK3, Paecilomyces-PP6, Paecilomyces-PP7, Paecilomyces-AG4, Paecilomyces-PYK4, Aspergillus PP2 and without antagonistic fungi (control). The result indicated that all antagonistic fungi isolate could persist on chili fruit. The highest persistence were Trichoderma-PP3 and TrichodermaAG2 (95.83%) and the lowest belonged to Paecilomyces-PP7 (50%). Trichoderma-PP3 and Trichoderma-AG2 were the best isolates for suppressing anthracnose disease caused by C. gloeosporioides.

Abstract

Assay of chitinolytic bacterial isolate of Bacillus sp. BK17 in peat and palm oil bunch compost as carrier media in inhibiting Sclerotium rolfsii and Fusarium oxysporum of chilli seedlings. Sclerotium rolfsii and Fusarium oxysporum have been known as causal agents of seedling-off of chilli. Biological control has been used as an alternative control to replace chemical control. This study was aimed to determine the viability and ability of chitinolityc bacteria Bacillus sp. BK17 in carrier media of peat and palm oil bunch compost and in growing media to control seedling-off caused by S. rolfsii dan F. oxysporum of chilli. Our previous study showed that Bacillus sp. BK17 could reduce disease severity and intensity. Bacterial viability was measured as colony number grown after 90 days of storage in minimum salt medium with colloidal chitin as sole C source. Reduction of disease infection was measured as seedling number infected by S. rolfsii dan F. oxysporum. Seedling performances were measured as seedling height, leaf number and dry-weight after 30-days of growth. The result showed that bacterial cell viability was still high in both peat and palm oil bunch compost both with and without colloidal chitin addition after 90 days of storage. It was also shown that during application bacterial cell could grow. Seedling performaces i.e. seedling height, leaf number and dry-weight showed to be normal or even increase compared to those of pathogenic fungal inoculation only and (-) control.
