Abstract

The plant-parasitic nematode (PPN) is often not recognized as important limiting crop production in Indonesia. This is largely caused by non-specific and non-dramatic above-ground plant disease symptoms, their microscopic nature, and partly caused by inadequate demonstration of the economic importance of this hidden pathogen. However, change in agricultural practices to meet the ever-increasing food demand along with global climate change may increase the risk of PPNs on crop productivity in the future. This paper reviews PPN inventory in Indonesia during the last three decades. Thirty-three genera of PPNs were found to associate with 25 host plants. Some genera were present at the densities that are considered as damaging levels in other countries. Results among surveys are difficult to compare because of differences in crop cultivar surveyed, cultivation practices, sampling unit and method, and nematode extraction techniques. Lack of field supporting data did not permit a valid assessment of nematode risk on a particular crop. The first record of several quarantined species has been reported, but not all of them have been validated molecularly. Challenges and opportunities to improve the future field survey are presented in this paper.

Abstract

Decomposition is an important process in nature, as it can break down organic matter into smaller particles and nutrients. Nutrients are returned to the environment and can be reused by other organisms. One important organism that plays a role in the decomposition process is termites because termites are able to decompose organic matter such as wood in all habitats. Different termite habitats can be seen in terms of different types of land use. Some types of land use, such as natural forests, secondary forests, palm oil plantations, and settlements, can be used as a test site for wood decomposition by termites. All types of land use can be found in Dharmasraya Regency, West Sumatra Province. The purpose of this study was to study the decomposition of wood by termites in several different types of land use. Four types of land use are selected from habitats with the least disturbed conditions to the extent of high habitat disturbances, namely natural forests, secondary forests, palm oil plantations, and settlements. The study was conducted in Dharmasraya Regency, West Sumatra Province. The research method uses pine wood bait (Pinus merkusii), measuring 1.9 cm x 1.9 cm x 25 cm. The wooden bait is winded for seven days, and the wood bait is weighed to gain its initial weight and measured moisture content. Furthermore, wood bait that has been installed is observed and re-weighed to gain final weight and measured water content. The results showed that deforestation in Dharmasraya, West Sumatra had an effect on reducing wood decomposition by termites. Five (5) termite species were found in wood bait, including Pericapritermes sp.1, Microtermes sp.1, Schedorhinotermes sp.1, Macrotermes gilvus, and Coptotermes curvignathus.

Abstract

Spodoptera frugiperda  (Lepidoptera: Noctuidae) has successfully invaded and spread to almost all provinces of Indonesia which may cause significant impacts on corn production. Local natural enemies could play an important role in managing this invasive insect, and more diverse ecosystems would benefit natural enemies. This study aimed to assess parasitization rates of S. frugiperda eggs by local egg parasitoids in three different corn ecosystems (agroforestry, rice field, and rainfed field) in East Java. Sentinel egg masses were used for this study by exposing eight-hour-old egg masses collected from the laboratory mass-rearing and left for 24 hours in corn plantations aged 7, 14, and 28 days after planting. Telenomus sp. was more abundant in the three ecosystems compared to Trichogramma sp. The egg mass parasitization varied from 15.6 to 52.5%. The number of egg masses parasitized was consistently higher in agroforestry, followed by rice fields and rainfed fields in all three different sampling times. Interestingly parasitization rates on egg masses were not different, and they ranged from 43.7 to 81.6%. These findings provide evidence on the importance of local egg parasitoids for managing S. frugiperda and some insights related to plant diversity to improving the services by these parasitoids.

Abstract

Helopeltis bradyi is often used as for research and is required in large numbers. The insects were obtained from cacao plants and reared with cucumber fruit in the laboratory. This study aimed to determine the biology and demography of H. bradyi reared on cucumber under laboratory conditions. The demographic parameters observed were net reproduction rate (Ro), gross reproduction rate (GRR), intrinsic growth rate (r), average generation period (T), and population doubling (DT). The results showed that the egg stage lasted for 6.33 ± 0.47 days, the developmental period of the I‒V instar nymph was 2.13 ± 0.34, 2.07 ± 0.25, 2.13 ± 0.34, 2.33 ± 0.47, and 3.20 ± 0.40 days. The lifespan of male imagoes were 32.33 ± 4.92 days, and female imagoes were 24.60 ± 6.64 days. The adult female pre-oviposition period was 2.2 ± 0.40 days and oviposition period of 22.9 ± 4.66 days. H. bradyi has a type III survival curve which indicated high mortality rates during the first instar egg and nymph population. Demographic statistics of H. bradyi on cucumbers fruit are GRR of 296 individuals per generation, Ro of 196 individuals per parent per generation, rate of r of 0.18 individuals per parent per day, T of  29.34 days, and DT of  3.85 days.

Abstract

The Indonesian government is obliged to ensure the public health of the people of Indonesia by the supervision of Fresh Food Originated from Plant (Pangan Segar Asal Tumbuhan [PSAT]) arriving from abroad. Therefore, the regulation of Minister of Agriculture Number 88 in 2011 was issued to regulate inspection requirement of PSAT. There are some challenges in the implementation of these regulations until 2015, such as the unavailability of accredited laboratories, the lack of communication between stakeholders, and limited human resource or utensil within testing laboratories. Most of the testing laboratories appointed by the government are not yet accredited. Only 60% are able to perform tests mandated listed in The Regulation of Minister of Agriculture No. 88 the Year 2011. On the other hand, private laboratories accredited by ISO/IEC 17025 showed higher capacity by being able to perform 77.8 to 100% of mandated tests. The implementation challenges were later addressed by the revision of the regulation and release of issue Regulation 04/2015 in ref. The Regulation of Minister of Agriculture 13/2016. These regulations acknowledge Food Safety System of the state of origin or their administration of the Testing Laboratory Registration. In other words, they put forward the implementation of supervision in the country of origin reducing Indonesia’s reliability on providing high level of testing laboratories itself. The implementation of The Regulation of Minister of Agriculture 04/2015 in ref. the Regulation of  Minister of Agriculture 13/2016 expected Quarantine Measures on the importation of PSAT to be more effective and efficient. Therefore, impact of the implementation of this new regulation would shorten delay periods for cargo containers in ports (dwelling time), reduce handling cost of containers, minimize laboratory testing fees, and reduce risk of rejection of imported products because of incompliance.

Abstract

The brown planthopper, Nilaparvata lugens Stål. (Hemiptera: Delphacidae), is one of the most important pests attacking rice plants. One of the strategies to control this pest is by using natural enemies, including egg parasitoids. This study aimed to investigate the species of N. lugens egg parasitoids and their parasitism levels in one rice ecosystem with different growth stages. The research was conducted by selecting three rice plots aged 3, 6, and 10 weeks after planting. Potted rice plants with N. lugens eggs were placed in those rice plots for two days and recollected for observations. The same release was repeated 3 weeks later at the same rice plots in the same site. Egg parasitoids of N. lugens found during this study were Oligosita sp. and Anagrus sp. The highest number of egg parasitoids were found at the rice plants aged 6 weeks after planting with 14.50 and 13.50 individuals collected during first and second trapping, respectively. In addition, the level of parasitism ranged from 6.89-22.26% with the highest parasitism was occurred in the 6-week old rice. These findings may suggest that different rice planting dates may benefit the egg parasitoids of N. lugens which could reduce the risk of outbreaks.

Abstract

Twisted disease caused by Fusarium spp. is one of the primary diseases on shallots with potency to cause enormous losses by causing stunting and bulb rot. One alternative disease control is the induction of plant resistance since the seed stage. The aim of this study was to determine the content of salicylic acid, jasmonic acid, and phenolic compounds of shallot bulb seeds coated with biological control agents as a resistance response to twisted disease. The shallot cultivar used was Crok kuning. The treatments used in this study were the type of biological control agents, including Rhizophagus intraradices and Trichoderma asperellum, combined with and seed coating application time (one month before planting and simultaneously at planting). Biological control agents in the form of powder formulation applied as seed coating material and seeds were stored for one month before planting. The results showed that application of biological agents delayed the occurrence of the twisted disease symptoms. The salicylic acid content from plant treated with R. intraradices at the time of planting was slightly higher than the control. The jasmonic acid content in T. asperellum plants treated at planting was higher than then control. Total phenolic content from plants treated with T. asperellum at planting time was higher than the control. In general, application of biological control agent as seed coat did not result in significant increase in salicylic acid, jasmonic acid nor the phenolic compounds, compared to the pathogen infected control.

Abstract

Metarhizium anisopliae is one of the most frequently used insect pathogen fungi in controlling Oryctes rhinoceros. This research aims to learn the potency of fungus M. anisopliae against O. rhinoceros larvae growth and development at the laboratory. The research methods used are T-tests comprising seven treatments and three replications. Fungi were applied in all larvae instar stages starting from the pre-molting of the first larvae instar, post-molting of the second larvae instar, active second larvae instar, pre-molting of the second larvae instar, post-molting of the third larvae instar, active third larvae instar, and pre-pupae stage which were then compared with each instar’s own control. The result indicates that fungus M. anisopliae is capable of suppressing O. rhinoceros growth and development. The fungus induced highest mortality rate of 87% to the third instar larvae and lowest mortality rate of 27% to the pre-molting of the first instar larvae. The fungus also affected the duration of larval stage. At pre-molting of the third larvae instar treated with M. anisopliae, the larval duration was 40 days compared to that of control that took 135 days. At the post-molting of the third larvae instar, the larval duration was 25 days compared to that of control that took 120 days. At the third larvae instar, the larval duration was no more than 15 days compared to that of control that reached 110 days. At pre-pupal stage, the larvae only lasted for 6 days while at control, they were able to last for 15 days. The fungus also affected the success of larva development in becoming pupae in all O. rhinoceros larval stage. The lowest success rate was found in the post-molting of the third larvae instar treated with M. anisopliae with 7% compared to its control with 100% while the highest success rate was found in the pre-molting of the first larval instar with 47% compared to its control with 93%.

Abstract

Plant Growth Promoting Rhizobacteria has been known for its ability to induce plant resistance on shallot against twisted disease. Its ability as a bioprotectant agent is estimated to be comparable to the efficacy of Trichoderma which is currently widely used as a biological control agent.. This study aims to determine the content of jasmonic acid, salicylic acid, peroxidase, and disease suppression in shallot by application of Bacillus velezensis B-27, Bacillus cereus RC76, and application with combination of both rhizobacteria. The application was carried out  with tuber dipping for 30 minutes in each treatment with a bacterial density of 108 CFU mL-1. Application using Trichoderma was used as the comparison treatment, and the control plot was not given any treatment. Pathogen inoculation was carried out simultaneously as planting using Fusarium acutatum with a spore density of 106 CFU mL-1. The jasmonic and salicylic acids content was measured using the High-Performance Liquid Chromatography method, and the peroxidase content was determined using the spectrophotometric method. Disease suppression was measured at 10-day intervals. The results showed that treatment with Bacillus cereus RC76 increased jasmonic and salicylic acid levels, while application with Bacillus velezensis B-27 showed the highest level of peroxidase. Treatments with Bacillus spp. were able to suppress twisted disease by 72.2% to 100%. This study demonstrated that application Bacillus spp. suppressed twisted disease on shallot and increased the jasmonic and salicylic acid content as induced resistance mechanism against pathogens.
