Abstract

Khapra beetle, Trogoderma granarium Evert (Coleoptera: Dermestidae) is the most important stored pest and was first discovered in Jakarta grain storages in 1972. Since then, quarantine procedures have been massively carried out to prevent khapra beetles to spread in Indonesia. In 2009, Indonesia has been declared as free area from Khapra beetle. However, Indonesia still import grain from non-Khapra beetle free countries and supervision must be carried out continuously to prevent Khapra beetle reinfestation. This survey was conducted at warehouses in five areas of Jakarta, Tangerang, and Bekasi from October 2016 to February 2017 with high risk due to its role as one of the main entry ports and storage of imported grains. Observation was done using probe sampling, direct observation and traps with attractant. Results showed that several insects were found from imported seeds in the surveyed area, but no Khapra beetles were found. It showed that non-Khapra free countries have implemented the required Sanitary Phytosanitary. In addition, it implies that survey methods using attractant traps could complement the probe sampling methods and direct observation that are currently used.

Abstract

Spodoptera frugiperda is a new pest in Indonesia that attacks corn and can cause up to 100 percent damageon young plants. As an invasive pest, information on potential indigenous natural enemies that cancontrol this pest is needed. This study aims to determine the effectiveness of indigenous entomopathogenic fungi and their application methods on mortality, feeding activity, growth, fecundity, and fertility of S. frugiperda. This study used a factorial Completely Randomized Block Design (RCBD) method consisting of 10 treatments. Treatmentstested werecombination of fungi species, namely Fusarium sp., Aspergillus oryzae, Entomophthora sp. with conidia density 109 ml-1, distilled water and cypermethrin at concentration of 1 ml.L-1 as a control. Two application techniques used were direct application on S. frugiperda larvae and diet test. Each treatment was repeated three times resulting in30 experimental units. Variables observed included mortality, feeding activity, growth, fecundity, and fertility of S. frugiperda. Results showed that the three fungi and cypermethrin treatment did not cause mortality, but reduced feeding activity, fecundity and fertility of S. frugiperda. Application of entomopathogenic fungi ondietswas more effective than directly spraying S. frugiperda larvae. The best treatment combination that suppressed feeding activity was the application of Aspergillus oryzae sprayed on S. frugiperda diet.It was also suspected that S. frugiperda larvae used in this test had developed resistance to cypermethrin.

Abstract

Sugarcane streak mosaic virus (ScSMV) is the most important viral disease of sugarcane in Indonesia with distribution in almost all commercial sugarcane plantations. The disease causes significant yield losses of both cane tonnage and sugar yield. The use of resistant varieties is the best approach for controlling viral diseases. This study aims to investigate resistance response of several introduced varieties against ScSMV in a glasshouse condition and the impact of the viral infection on chlorophyll and proline content in sugarcane leaves.  Sugarcane plants were inoculated using ScSMV inoculum one month after planting using an abrasive pad rubbing method. Disease incidence and severity was observed at week 4-12 after inoculation and variety resistance levels were classified based on disease incidence. Confirmation of the virus was done by RT-PCR. Spectrophotometer was used to measure chlorophyll content at dual wavelengths of 645 and 663 nm, and proline content at wavelengths of 520 nm. The results showed that most of the tested varieties were susceptible to ScSMV. There are six highly resistant varieties, namely SRA 1, SRA 2, N 10-4, N 10-7, N10-9, and N 10-13, but these varieties still require to be tested on a field scale. ScSMV infection generally decrease chlorophyll and proline content. However, the physiological effect of ScSMV infection on chlorophyll and proline content needs further investigation.

Abstract

Calotropis gigantea produces secondary metabolites. Some toxicity tests on several pest species had been conducted, yet the most susceptible pest species towards C. gigantea extract is still unknown. This study aims to determine the susceptible insect species and study the behavior of susceptible insects to C. gigantea extract. The test methods used in this research were leaf dipping and spraying upon four insect pest species of different orders (Bactrocera carambolae [Diptera: Tephritidae], Nilapavata lugens [Hemiptera: Delphacidae], Sitophilus zeamais [Coleoptera: Curculionidae], and Plutella xylostella [Lepidoptera: Plutellidae]). The concentration used to determine susceptible insects was 25 g.L-1 and control. Deterrence test of susceptible insects using a choice test and no-choice for 1.5 hours observed every five minutes. Five replication were used for each concentration. Behavioral test of susceptible insects using dietary toxicity test. Five bok choy leaf disc was immersed into solutions for 1 minute and air-dried on a petri dish. Observations were carried out for 12 hours with an observation period of every 1.5 hours. A leaf dipping test for 12 hours with an observation period of every 1.5 hours using the feed method. The concentrations used were 12.5 µgL-1and control. The concentration used was the toxicity test of C. gigantea leaf extract 25, 12.50, 6.25. 3.12, 1.56, 0.78, 0.39, 0.19, 0.09, 0.04 µgL-1. P. xylostella was considered a more susceptible test insect towards C. gigantea leaf extract than B. carambolae, N. lugens, and S. zeamais. C. gigantea leaf extract showed a toxic and feeding deterrent to P. xylostella larvae. The LC50 value of C. gigantea extract against P. xylostella by dipping was 16.9 µg.l-1 and 18.5 µg.l-1 by spray. The components of C. gigantea leaf extract consist of alkaloid, tannin, phenol, flavonoid, saponin, and terpenoid. The result of the research showed that C. gigantea leaf extract has a toxic and deterrent substance against P. xylostella and potential to control P. xylostella.

Abstract

Fall armyworm or Spodoptera frugiperda is one of the main pests of corn. It can caused up to 28.08% yield loss. Pest control efforts with broad-spectrum insecticides can cause negative impacts that disrupt ecosystems, non-target biotic factors and the surrounding environment. Beauveria bassiana is an alternative biological control agent that is target-specific. This study was conducted to determine toxic and antifeedant activities of B. bassiana application on third to fifth-instar S. frugiperda larvae. B. bassiana isolates were propagated using corn flakes media and resulted in colonies with conidia density of 1.1×108conidia.g-1. This study used a completely randomized design with 5 treatments and 5 replications. Treatments consisted of P1 namely B. bassiana propagation with a concentration of 60 g.L-1, P2 = 70 g.L-1, and P3 = 80 g.L-1. P0 was a negative control (untreated with B. bassiana) and P4 was a positive control (diazinon with concentrations of 2 ml.L-1). The variables observed were mortality and weight of the leftover feed. The results showed that the formulation of B. bassiana with concentrations of 80 g.L-1 was able to infect armyworms with a mortality percentage of 53.5% which was statistically similar as the effect of chemical insecticides. In addition, inhibition of feeding activity due to treatment could prevent leaf damage up to 68.21%.

Abstract

Brassicaceae are known to contain compounds that are biofumigants. This study aimed to determine the effect of Brassicaceae waste application on soil nematode community. Broccoli leaves and stems (Brassica oleracea var. italic), cabbage leaves and stems (B. oleracea var. capitate), kailan stems (B. oleracea var. alboglabra), radish leaves (Raphanus sativus), and leaves of kamanilan weed (Rorippa indica) were tested in this study. The total glucosinolate content of Brassicaceae waste was estimated using the palladium method with a modified spectrophotometer. The experiment was carried out in polybags containing 500 grams of soil-infested nematodes. Brassicaceae waste (15 grams/polybag) was chopped and mixed into the soil, watered, and polybags were tightly closed for 14 days. The experiment was arranged in a completely randomized design with nine treatments and five replications. The results of the total glucosinolate analysis showed that broccoli, radish, and kamanilan leaves fall into the high category (144.7-185.2 µmol/g); cabbage leaves, cabbage stems, and kailan stems fall into the medium category (52.0-56.0 µmol/g); and broccoli stems fall into the low category (35.4 µmol/g). There was no correlation between total glucosinolate contents and their effect on suppressing soil nematode communities at the applied effluent dose. The population of bacterivorous nematodes increased in each waste treatment, especially in kamanilan leaf treatment (R. indica) which reached 13,008 individuals. These results indicate that kamanilan weed has good potential to improve soil health. The treatment of Brassicaceae waste against soil nematode communities showed a low diversity index, an uneven evenness index, and a high dominance index.

Abstract

The demand for shallots has increased along with the Indonesian population. To achieve shallot production goals, farmers began to plant shallots outside usual planting season. However, unfavourable environmental conditions and pest attacks are obstacles faced by farmers. The use of Biological Control Agents (BCA) is a way to improve plant growth and protect plants against plant pathogens or even abiotic stresses. The purpose of this study was to evaluate the response of shallot plants after BCA (Bacillus and Mycorrhizal Fungi) application, especially against twisted disease during off-planting season. This research was conducted by preparing BCA isolates, applying BCA, measuring disease incidence and intensity, observing plant growth development, analyzing phenol content, and analyzing phosphate content. Results showed BCA Bacillus and mycorrhizal fungi did not inhibit Fusarium spp. infection. Agronomic measurements showed no significant difference in crown weight and root weight, but isolate B8 significantly increase the number of leaves while isolate M significantly decreased plant height. Isolates B6, B7, and M significantly reduced the total phenol content in shallot plants. Phosphate analysis on isolate M did not have significant effects on shallot plants, while BCA Bacillus and Mycorrhizal fungi application could not suppress twisted disease. Nevertheless, B8 treatment has the potential to increase shallot growth; therefore, further research must be conducted.

Abstract

Bemisia tabaci is an agricultural pest that interferes plant growth, as well as being an insect vector of various types of viruses, one of which is the geminivirus group. B. tabaci is called Cryptic Species Complex due to their similar morphology but has different genetic profiles. Climate change and increased global trading of agricultural products could increase B. tabaci population and lead to the emergence of genetic disparity. This study aims to obtain the latest information on the population homogeneity of B. tabaci in four districts of the Yogyakarta and potential differences on their nucleotide arrangements. Molecular identification was performed using PCR and primers C1-J-2198/L2-N-3914 on B. tabaci. B. tabaci COI gene sequences were then compared using a phylogenetic analysis and similarities of nucleotide bases were determined. Results showed that the populations of B. tabaci in Yogyakarta were still homogeneous showed by biotypes similarity, namely the non-B biotype. B. tabaci from Yogyakarta have nucleotide base similarity of 100% with B. tabaci from Singapore (AY686095) and Thailand (AY686092) and 99.56% with species from Bangladesh (AJ748388). Results also showed no differences in the composition of both nucleotide bases and amino acids from the four districts of B. tabaci sampling location. The homogeneous population of B. tabaci and the high incidence of yellowing disease caused by Begomovirus in chili pepper plants in the Special Region of Yogyakarta prove that it is necessary to review the current methods of controlling B. tabaci pests.

Abstract

Spodoptera frugiperda J.E. Smith (Lepidoptera: Noctuidae) is a new pest on maize that has successfully spread to various regions in Indonesia. This pest can cause severe damage to the affected plants. Most farmers have relied on synthetic insecticides for control. This research was conducted to determine susceptibility level of S. frugiperda larvae to emamectin benzoate, chlorantraniliprole, and spinetoram insecticides by using the diet-dipping method. There is no registered insecticide to control S. frugiperda, so the three types of insecticides used were based on the recommendation of the Ministry of Agriculture of the Republic of Indonesia. Five field-collected population from Central Java and a laboratory populations of S. frugiperda were used to develop a baseline susceptibility for each insecticide. First instar larvae of S. frugiperda were placed in vials containing artificial diet treated with insecticides and an untreated control (treated with water only), observed for mortality on the seventh day and data was analyzed using probit. S. frugiperda from Tegowanu was the most susceptible to emamectin benzoate (LC50 = 0.11 mg/L), while the least susceptible population was from Wedi (LC50 = 0.39 mg/L) with the resistance ratio (RR) values of 0.45-folds and 1.60-folds compared to the laboratory population, respectively. S. frugiperda from Ngombol was the most susceptible population to chlorantraniliprole (LC50 = 12.63 mg/L), while the least susceptible population was from Tegowanu (LC50 = 30.29 mg/L) with RR values of 0.90- and 2.15-fold compared to the laboratory population, respectively. Meanwhile, S. frugiperda from Jogonalan was the most susceptible to spinetoram (LC50 = 2.75 mg/L), while the population from Wedi was the least susceptible (LC50 = 5.94 mg/L) with the RR values of 0.52- and 1.12-fold compared to the laboratory population. Field-collected S. frugiperda populations were still susceptible to the three tested insecticides tested and emamectin benzoate being the most toxic compared to spinetoram and chlorantraniliprole.

Abstract

Actinomycetes are Gram-positive filamentous bacteria used as biocontrol agents against pathogens. Currently, little research on actinomycetes has been published in Indonesia. The study provides issues related to the most relevant keywords in actinomycetes, the most productive authors and countries on actinomycetes research, current research on actinomycetes, and future topics in actinomycetes research. This paper aims to understand the current status and trend of research on actinomycetes in biological control, especially their acts as biocontrol agents. We used VOSviewer and CiteSpace software to perform a scientometric and bibliometric analysis. Out of 452 Scopus publications published between 1971 and 2022. Research on actinomycetes has increased rapidly since 2000, leading to an exponential trend. The result shows that >50% of papers focus on Agricultural and Biological Sciences and indicate that actinomycetes are mainly applied as biocontrol agents. China is the most documented and powerful country, followed by the United States and Iran. In contrast, Indonesia ranks 19th in the world with nine published papers. Scientometric analysis shows Shahidi Bonjar nominated as the strongest citation burst author (4.01). Their topic is mainly on the biological control of pathogens by Actinomycetes, especially Streptomyces sp., while fungi are a dominant pathogen. These findings are related to bibliometric analysis, showing Streptomyces spp. and fungi are two primary keywords in the Scopus database, found on 183 and 139 documents. We found actinomycete research focuses on their ability to manage plant diseases naturally. In the future, we predict actinobacterial research is still essential to biological control, particularly those involving Streptomyces species. Also, several important topics are associated with their activities in controlling pests (nematode), postharvest disease, and growth promoter ability.
