Abstract

The study focuses on the comparison of farmers information literacy who had visited the demonstration area and social media of the Pacitans Agricultural Technology Park (TTP). Quantitative method was used to research and purposive sampling was used to select sample in Pacitan district. 167 farmers were selected as the sample form 6 subdistrict. Variable of research are farmers characteristics, the existence of TTP Pacitan, and farmer information literacy for agricultural technology. Non parametric statistical was used to analysis of comparison and correlation. The results showed (1) the farmers characteristic who social media acces younger and more income than farmer who visit to demonstration area ,(2) the existence of TTP Pacitan in the demonstration area is significantly different (0.000 <0.05) than existence on social media. The implementation of the functions of dissemination, extention/training, entrepreneurship development, and making agro-educational-tourism areas in the demontration area is higher than on social media, (3) the information literacy of farmers who visit the garden are significantly different (0.000 <0.05) with farmers who access the social media. Farmers who visit the demonstration area higher information literacy than farmers who visit social media, (4) overall, the farmers age (0.034 <0.05), smartphone ownership (0.001 <0.05), and existence of TTP Pacitan (0.000 <0.05) are related to farmer information literacy. Partially, the existence of TTP Pacitan both demosntration area and social media is related to farmers information literacy. The balance of TTP Pacitan existence in demonstration area and social media can increase farmers information literacy achievements rtoward agricultural technology.

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

Zeugodacus cucurbitae Coquillett is one of the most detrimental pests that mostly attack family Cucurbitaceae. Control over this pest often uses insecticides, and one of the plants with the potentiality to be used as source of insecticide is Polyscias guilfoylei. This research aimed to study the influence of P. guilfoylei leaf extract application upon Z. cucurbitae mortality and to determine the LC50 value. The research was conducted at Pest Invertebrate Plant Pest Science Laboratory, Department of Plant Protection, Faculty of Agriculture, Universitas Gadjah Mada. The toxicity test was done using contact, oral and residue methods upon ethanol and n-hexane extracts with 0; 1.25; 2.50; 5.00; 10.00; and 20.00% concentrations. The research used randomized group design with six replications. The parameters observed were the number of dead melon fly at 72 hours after the treatment and LC50 value of each extract. The data were analyzed using Probit analysis via 1.02 version of Lenora software Polo Plus. The result shows that ethanol and n-hexane extracts of P. guilfoylei leaf using oral and residue methods affected Z. cucurbitae mortality. However, in contact method, ethanol and n-hexane extracts of P. guilfoylei leaf did not affect Z. cucurbitae mortality. LC50 values of ethanol extract using oral and residual methods were 6.168% and  3.658%, respectively. LC50 values of n-hexane extract using oral and residual method reached 5.311% and 6.607%, respectively. This research shows that ethanol and n-hexane extracts of P. guilfoylei leaf contain secondary metabolites that are toxic for melon fly Z. cucurbitae.

Abstract

Sitophilus oryzae is a cereal product pest found in warehouses. The presence of this pest negatively impacts the quality and quantity of stored rice. The common method used to control warehouse pests is fumigation. However, frequent use of insecticides will trigger resistance within target pest populations. This study aimed to develop a bioassay method based on the Food Agriculture Organization (FAO) protocols and modify bioassay protocols to determine S. oryzae susceptibility of populations collected from traditional markets across Yogyakarta. Field populations were collected from eight traditional markets in Yogyakarta (Lempuyangan Market [Kapanewon Danurejan], Kranggan Market [Kapanewon Jetis], Caturtunggal Market [Kapanewon Depok], Godean Market [Kapanewon Godean], Imogiri Market [Kapanewon Imogiri], Pleret Market [Kapanewon Pleret], Kasihan Market [Kapanewon Lendah], and Brosot Market [Kapanewon Galur]). The reference population was obtained from the Southeast Asian Regional Centre for Tropical Biology(SEAMEO BIOTROP). The bioassay was carried out following FAO protocols by using a glass jar fumigation chamber (volume 2 L) which was a modification of the desiccator of FAO recommended method number 16. This test used the lowest testable dose for this method: 0.01 × 10-2 mg/2L or 0.5 × 10-2 µg/L tested on 100 imagoes which were divided into five replications and obtained 100% mortality on the second day (48 hours). Results showed that the FAO fumigation chamber method could not be used in the test, so modifications were carried out to determine tested doses by changing the volume of the fumigation container. The test used three container volumes, including 20, 60, and 80 L. Result from 20 L container showed 82-100% mortality, 60 L containers showed 69-100% mortality, and 80 L containers showed 24-79% mortality. Results from 80 L container was suitable for the bioassay because it was able to test the lowest dose on reference insects. Eight doses ranging from 0.125 to 1.625 × 10-2 µg/L, and an untreated control were used to determine the LD50 of phosphine on each population. Insects were fumigated for 48 hours and then removed to observe mortality. The LD50 of the reference population was 0.27 × 10-2 µg/L while 0.29-0.54 × 10-2 µg/L for field populations. These findings indicate that S. oryzae populations collected from traditional markets in Yogyakarta were still susceptible to phosphine.

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

Spodoptera exigua Hubner (Lepidoptera: Noctuidae) is the main pest of shallot causing significant economic losses. The continuous use of insecticides has resulted S. exigua to develop resistant against them. This study aims to determine the level of S. exigua resistance of Nganjuk and Bantul populations against methomyl, chlorfenapyr, and emamectin benzoate and temporal resistance of S. exigua of Nganjuk population to methomyl. Nganjuk population were sampled in June, September, and December. First instar larvae from the first generation were used tested using the leaf-dipping method. Temporal resistance test was carried out using the same concentrations. The resistance ratios of Nganjuk population to the insecticides methomyl, chlorfenapyr, and emamectin benzoate were 58.8; 8.8; and 2.5 fold respectively. The LC50 values of S. exigua of Nganjuk population collected in June, September, and December were 1127.44; 50.62; and 366.76 mg [AI] liter-1, respectively. The results of this study indicated that the S. exigua of Nganjuk population was highly resistant to methomyl and its level has changed over time. Resistance management by rotating the type of insecticide is not sufficient but should also consider its change of resistance pattern over time.

Abstract

Farmers empowerment through informal institution has a long history in modern Indonesian farming. Some groups evolved from farmers' own iniatitive, but many were formed after the government's urging. SLPHT (Integrated Pest Management Farmer Field School), an unconventional way to release IPM program and concept has relatively suceeded in institutionalizing farmers by dynamizing farmer groups. Although this has been an advantageous progress, the problem lies in care, management and funding for those institutized empowerment. Without careful planning in maintenance, management and funding, the success of these efforts may prove futile.Keywords: Farmers Empowerment, Institutional, Farmers Field School.

Abstract

The Asian corn borer, Ostrinia furnacalis (Guenée) is an important economic pest of corn and is widely distributed in the Asia-Pacific region, including Indonesia. The objective of this research is to investigate the effect of infestation levels of O. furnacalis larvae per plant on corn grain yield reductions, and to determine economic injury levels (EIL) of O. furnacalis larvae at three growth stages (V10, R1, and R2) of corn. The experiment was designed in a split-plot randomized complete block with blocks replicated three times. Differences in grain weight between the uninfested and highest infestation levels (six larvae per plant) V10, R1, and R2 were 59.81; 58.76; and 49.20 g/plant, respectively. For each additional infestation by one larvae per plant at V10, R1, dan R2, there is reduction in grain weight of 4.94%, 4.56% and 3.76% respectively. The calculation of EILs was based on the proportion of yield loss per larvae per plant on three corn growth stages with the assumption that pesticide control reduced 67% of O. furnacalis population. The lowest EIL was 0.31 larvae per plant at V10 when the cost of control reaching Rp.125,000 per ha and crop value of Rp.12,000,000 per ha. The highest EIL of 1.24 larvae per plant was found at R2 with the cost of control of Rp.250,000 per ha and crop value of Rp.8,000,000 per ha.
