Abstract

Pujiastuti et al, 2019.The Existence of Insect Species in Various Intercropping Vegetable Crops: Case Study in Talang Pasai Village, Pagar Alam Utara District, Pagar Alam City South Sumatra. pp. 103-109.Intercropping plants are a cropping system that is widely applied by farmers ie planting more than one species of plant. In addition to increasing crop production, intercropping systems are also optimize land functions. Intercropping systems are also wellknown to affect the diversity of insects that live or visit plants. The aim of the study was to identify insects  living on plants or around plants and their role in intercropping systems. Research had been carried out in the highlands in the North Pagar Alam District, Pagar Alam City, South Sumatra, in July-August 2018. Insect observation methods were conducted by direct observation and hand picking. Observations were carried out 3 times with 1 week observation interval. The types of intercropping observed included red onions, chili-celery, chili-cabbage and eggplant-carrots. The results of observations on plants intercropping in which  chili plants as one of the crop showed chili plants were more visited, seized or attacked by insects compared to their partner plants. In the chili-red onion plants, it was  found 4 orders, 5 families and 6 species, in chili-celery plants found 4 orders, 5 families and 10 species, in chili-cabbage plants found 5 orders, 6 families and 8 species, whereas in the eggplant-carrot plants found 5 orders, 11 families and 13 species. Intercropping with chili plants shows that their partner plants are less attacked by pests.

Abstract

Rice cultivation in tidal area faces many obstacles. Rodent is one of important pests attacking rice both in vegetative and generative phases. The objectives of this research were to study the rat species and population, footprints, symptoms and level of rice damage and rice production by Trap Barrier System (TBS). The study was conducted in Jalur 6 of Muara Telang Banyuasin district, South Sumatera, 2016-2017. The research was carried out in two hectares of rice field with one hectare TBS and one-hectare non-TBS. Observation of rat population was done three times, during vegetative stage (30 days after planting/dap), reproductive stage (65 daps) and ripening stage (100 daps). One species of rats had been found namely Rattus argentiventer. In non-TBS, rat population was lower. However, in the damage level, the rat population was higher than in TBS. The number of R. argentiventer male captured was more extensive than the female. The number of footprints did not represent the number of rodents caught. The existence of rat footprints was indicating the existence of rat effort to approach the rice plant. The yield of rice was higher in TBS area.

Abstract

The brown planthopper (BPH), Nilaparvata lugens can cause direct damage and transmit rice diseases.  Beauveria bassiana is used to control BPH, however the success of the fungal efficacy on rice fields is affected by external factors, such as temperature. This research aimed to evaluate the conidial viability and density of B. bassiana isolates from Java and Sumatra, exposed to 25 and 34°C and their virulence against BPH nymphs. Twenty six isolates of B. bassiana cultures incubated at 25 and 34°C for 7 days were observed on their conidial density, viability, and  virulence against BPH nymphs. The incubation temperature of 34°C was able to decrease conidial density and viability, and virulence of the isolates.  However, some isolates of B. bassiana originated from soils or insects in Sumatra, especially from South Sumatra still produced high conidial density and viability as well as high virulent against BPH nymphs, such as TS1D3A, TSID3B, TS1D2A and TS1D2B isolates. The TS1D2B isolate incubated at 34°C still caused the highest percentage of BPH mortality (43.33%)  among other isolates. Therefore, the isolates can be used as promosing candidate for  biocontrol for N. lugens on rice planted in tropical ecosystem, such as wetland or lowland rice ecosystems in Indonesia.

Abstract

The use of golden snail meal to enrich Bacillus thuringiensis culture media and its effect on the bacterial toxicity against spodoptera litura. Bacillus thuringiensis is an entomopathogenic bacterium producing spore and protein at sporulation.  There has been limited research on using golden snail as protein resource to enrich bacterial culture media.  This research was aimed at studying bacterial cell/spore production in culture media made from coconut water media and liquid waste of tofu industry (tofu whey) enriched with golden snail meal (GSM), as well as its toxicity against Spodoptera litura. The research was conducted in the Laboratory of Entomology, Department of Plant Protection, Faculty of Agriculture, Sriwijaya University, from June to September 2017. The experiment was arranged in a Factorial Completely Randomized Design (FCRD) with two factors and three replications. The first factor was the addition of GSM (0, 5, 9, 13 and 17 g) and the second was storage longevity (0, 1, and 2 months). Number of test insect (third instar of S. litura) was 30 larvae per treatment.  Parameter observed were spore density, larval mortality, and symptom of infected larvae.  The results showed that B. thuringiensis cultured in culture media enriched with 13 g golden snail meal produced the highest spore density, amounted to 14.14 x 107spores/ml and caused larval mortality up to 86.67%. After one and two month storage treatments, the spore density in the cultures reduced to 2.51 x 107 and 1.49 x 107 spores/ml, respectively. There was a tendency of reduction in spore density under longer storage of the culture. Survived larvae developed abnormally, failed to transform to pupa or imago.

Abstract

The plants surrounding rice field serve as a habitat and niche for entomophagous arthropods. This study aimed to identify the entomophagous arthropod species and to analyze their abundance and community in vegetables and refugia grown in the rice field. The field was surrounded by 4 species of refugia (Zinnia sp., Tagetes erecta, Cosmos caudatus, and Sesamum indicum) and 4 species of vegetables (Vigna unguiculata, Momordica charantia, Cucumis sativus, and Luffa acutangula). The arthropod found were 67 species of predatory arthropods and 22 species of parasitoids. The predatory arthropods were mostly found in rice (51 species) followed by Zinnia sp. (15 species), and M. charantia (9 species). Parasitoid species were dominantly found in rice (19 species), Zinnia sp. (7 species), and M. charantia (6 species). The predatory arthropods mostly found were Tetragnatha javana, Tetragnatha virescens, and Paederus fuscipes, while the dominant parasitoids were Cardiochiles sp., Elasmus sp., and Snellenius sp. The parasitoid species composition in rice was more similar to those in bitter melon and zinnia. The composition of predatory arthropod species in rice was similar to those in all vegetables and refugia, except in cowpea. Zinnia sp. and M. charantia were the most chosen habitat by entomophagous arthropods.

Abstract

Desa Sejaro Sakti terletak di Kecamatan Indralaya ibukota kabupaten Ogan Ilir Sumatera Selatan. Potensi peternakan sangat besar dengan jumlah ternak sapi yang banyak dan ladang penggembalaan yang cukup luas. Salah satu jenis limbah yang dihasilkan berupa urin sapi. Limbah cair tersebut belum dimanfaatkan dengan baik. Sebagai bahan yang mengandung unsur karbon dan nitrogen (C dan N), urin sapi dapat dimanfaatkan sebagai media pembuatan bioinsektisida berbasis bakteri entomopatogen, Bacillus thuringiensis. Dalam aplikasinya, urin sapi diperkaya dengan penambahan 5% molase. Hasil penelitian sebelumnya menghasilkan data tentang kandungan spora dan protein bakteri B. thuringiensis yang dapat mematikan serangga hama. Pada umumnya bioinsektisida berbasis B. thuringiensis digunakan untuk mengendalikan serangga hama namun aman bagi musuh alami. Tujuan kegiatan pengabdian ini untuk memperkenalkan cara membuat bioinsektisida berbasis B. thuringiensis dengan bahan dasar limbah urin sapi. Sasaran kegiatan ini adalah kelompok tani di Desa Sejaro Sakti. Kegiatan diadakan mulai buan September-November 2019. Metode kegiatan berupa penyuluhan dan sosialisasi tentang potensi desa, arti penting dan manfaat limbah urin sapi, serta demonstrasi pembuatan bioinsektisida. Hasil kegiatan pengabdian menunjukkan bahwa petani sangat antusias mendapatkan pengetahuan dan ketrampilan tentang pembuatan bioinsektisida berbasis B. thuringiensis. Sebagian besar petani peserta kegiatan paham tentang cara pembuatan bioinsektisida. Mereka menyatakan bahwa pembuatan bioinsektisida tersebut merupakan hal baru dan mereka berminat untuk mempraktekkannya. Telah disadari bahwa selama ini pengendalian serangga hama biasanya dilakukan dengan menggunakan insektisida kimia. Oleh karena itu, untuk mengurangi biayaa pengendalian, mereka akan menerapkannya dalam usaha pengendalian hama di lahan pertanian. Hasil uji coba yang dilakukan di lahan terbatas menunjukkan bahwa lahan yang menggunakan bioinsektisida B. thuringiensis menunjukkan pertumbuhan tanaman yang lebih baik dibandingkan dengan tanpa perlakuan.

Abstract

Rice-field rat is a main pest of rice. Yield reduction caused by rat is quite high, because rats attack rice plant at all stages. One of the efforts applied to control rats is by using Trap Barrier System combined with cage trap. The objective of this research was to identify species of rat attacking rice plants and investigate the presence of  rat by their footprints. The experiment was conducted in Jalur 6  Village Sumber Mulya, Sub-district  Muara Telang,  District Banyuasin, South  Sumatra. One hectare of farmer’s rice field, divided into 3 sub-plot. Each sub-plot was planted with variety paddy of Inpari 22 (sub-plot A), Inpari 33 (sub-plot B), and Inpari 43 (sub-plot C). The number of cage traps was 6 traps per sub-plot. Observations were made 7 times, with an interval of 10 days. Results showed species of trapped rats in the research area was Rattus argentiventer, in which number of males was higher than females. Morphologically, the size of males were bigger than female. Number of footprints did not reperesentative the number of trapped rats. Inpari 43 variety was more preferred by rats because damage intensity was the highest than other two rice varieties.
