Abstract

Wereng batang coklat atau WBC (Nilaparvata lugens Stal.) merupakan salah satu hama utama pada tanaman padi yang dapat menyebabkan kerusakan dalam waktu relatif singkat. Serangan hama ini mulai mengemuka di Sumatera Barat sejak tahun 2009-2017. Insektisida berbahan aktif buprofezin adalah salah satu insektisida yang banyak digunakan untuk mengendalikan populasi WBC. Pelatihan cara menakar dan aplikasi buprofezin ini telah dilaksanakan di Keltan Rambutan Kelurahan Bungus Barat dan Keltan Sakato Kelurahan Lambung Bukit, Kota Padang. Tujuannya adalah untuk memperlihatkan kepada petani kemampuan insektisida berbahan aktif buprofezin selama 1 jam terhadap 10 ekor WBC yang disediakan. Perlakuannya berupa aplikasi buprofezin pada dosis tertentu (½ dosis anjuran, dosis anjuran, 1½ dosis anjuran), masing-masing dalam 5 ulangan. WBC yang digunakan merupakan populasi lapangan dari lahan persawahan Kecamatan Pauh. Hasil pengujian di Keltan Rambutan menunjukkan bahwa insektisida sesuai dosis anjuran mematikan 20% WBC, dan di Keltan Sakato mematikan 24% WBC, dosis anjuran mematikan 26% WBC dalam satu jam. Dosis anjuran Buprofezin memang tidak ditujukan untuk mematikan 100 % wereng uji, namun lebih kepada dampaknya terhadap penghambatan ganti kulit 2-3 hari kemudian.

Abstract

Jorong Parit Dalam Nagari Taeh Baruah, Payakumbuh District, Limapuluh Kota Regency is one of the villages that has various problems such as drought, high number of idle lands and remote access. The main crop planted during the rainy season is lowland rice, but most of the land becomes idle land during the dry season. In terms of fertilization, farmers in this location still use artificial fertilizers (chemical fertilizers) and in terms of pest and disease control they still use chemical pesticides. The solutions that can be offered are planting chili plants which are more resistant to drought, processing agricultural waste into compost as an alternative to reduce dependence on the use of chemical fertilizers, use of Trichoderma and vegetable pesticides as agents for controlling pests and diseases, and processing chili production to increase value. selling, competitiveness and community income. The purpose of this farmer group empowerment activity is to increase public knowledge about the use of Trichoderma which can increase the growth of chili plants, and can also be used as a biological agent to control pests and diseases that often attack chili plants when cultivated. The method used in this activity is socialization and counseling, structured training and direct practice in the field of Trichoderma's influence on the growth and production of chili plants. The results obtained from this activity are that the community can recognize that there are alternative controls that are more environmentally friendly than the use of synthetic pesticides. The public can also gain new understanding regarding the increased growth and yield of chili plants by utilizing the Trichoderma biological agent. So that in the end it can reduce dependence on synthetic pesticides obtained from outside. Therefore, the environment and the balance of the ecosystem in the Nagari Taeh Baruh area are maintained. The conclusion of this activity is that plant growth applied using Trichoderma spp is higher than plants that are not treated with Trichoderma spp (control). The use of Trichoderma spp is highly recommended because besides being easy to obtain, it also provides positive values for plant growth and is good for environmental technology around cultivated plants.

Abstract

Metarhizium spp. is one of the entomopathogenic fungus that can be used to control Spodoptera litura. The purpose of this research was to study the pathogenicity of Metarhizium spp. to Spodoptera litura eggs. The isolates were collected from rhizosphere of different crops i.e., cabbage, onion, leek and chili. The results showed that there was effect of all isolates on egg mortality. Mortality of S. litura eggs depend on the fungal isolates, ranged between 19.79%-75.70%. First instar larvae was also died 3 days after eclosion. The maximum mortality of first instar larvae was 58.65%. At a concentration of 108 conidia/ml, isolate Mt-kb had the highest virulence which caused higher mortality of eggs and first instar larvae.

Abstract

The attacks of brown planthopper or BPH (Nilaparvata lugens) in West Sumatra have been recorded since 2012 and continued to increase throughout 2015-2017. Wolf spider (Pardosa pseudoannulata) and lady beetle (Verania lineata) are two predators that can be used as natural enemies. Some research reports that the wolf spider can consume the BPH as much as 5-15 individuals while lady beetles consume as much as 1-11 individuals per day. Training on the use of two predators was carried out in farmer group of Rambutan, Kelurahan Bungus Barat and farmer group of Sakato Kelurahan Lambung Bukit, Padang City. The training aimed to show to farmers the predation rate of both predators against ten individuals of BPH provided. The treatment consisted of the predation rate of both predators (1 individual of wolf spider, 1 individual of lady beetle, 1: 3 composition of the joint predator) in 3 replications. All wolf spiders, lady beetles and BPH used were collected from rice field in Pauh District, Padang City. Within one hour, joint predators in Rambutan were able to consume 53% of the BPH provided, while joint predators in Sakato were able to consume 43%. Some efforts from farmers are needed to protect and conserve the presence of two predators so that they can act as natural enemies in the field.

Abstract

Camel groundbeetle (Ophionea nigrofasciata Schmidt-Goble 1846) or CGB is reported as one of predators of brown planthopper (Nilaparvata lugens Stal 1854) or BPH. The difference in BPH densities is assumed to affect the predation rate of the CGB. This study aimed to determine the predation rate of CGB on BPH at different densities. This experiment used a completely randomized design (CRD) consisting of six treatments and five replications. The treatment consisted of predation of one CGB at several BPH densities (5, 10, 20, 30, 40, and 50 individuals). BPH used was second-third instar of nymphs, and the CGB used was female. The results showed that the predation rate of CGB increased with increasing BPH density with functional response types classified as type I (Linear). The highest predation occurred at 50 density (23.6 individuals or 47.2% of BPH provided). The difference in density of BPH did not affect the bodyweight gain of CGB and tended to decrease due to different prey-seeking behavior.

Abstract

Wereng batang coklat (Nilaparvata lugens Stal.) merupakan hama utama yang menyebabkan rendahnya produksi tanaman padi. Pengendalian hama ini dapat dilakukan dengan pemanfaatan agens hayati. Salah satunya cendawan Beauveria bassiana (Bals.) Vuill. Tujuan penelitian adalah untuk mengetahui pengaruh cendawan B bassiana yang diinokulasikan melalui benih padi selama 24 jam terhadap preferensi oviposisi imago Wereng Batang Coklat (WBC). Penelitian disusun dalam Rancangan Acak Lengkap (RAL) dengan 5 perlakuan dan 5 ulangan. Perlakuan terdiri dari empat isolat B.bassiana yaitu: BbJg, BbWS, Pb211, Td312 dan kontrol. Konsentrasi B. bassiana yang digunakan adalah 108 konidia/ml. Data yang didapat diolah dengan menggunakan sidik ragam atau analisis of variance (ANOVA), dan dilanjutkan dengan uji LSD taraf nyata 5%. Hasil penelitian menunjukkan bahwa semua isolat cendawan B. bassiana mampu mengkolonisasi semua bagian tanaman padi dan tingkat kolonisasi tertinggi terdapat pada daun. Kemampuan kolonisasi dipengaruhi oleh jenis isolat. Keberadaan cendawan B. bassiana di dalam jaringan tanaman padi memberikan pengaruh negatif terhadap preferensi oviposisi imago betina WBC. Jumlah telur yang diletakkan imago lebih sedikit pada tanaman padi yang diaplikasi B. bassianadan persentase telur yang menetas juga lebih rendah dibandingkan dengan control. Cendawan B. bassiana dengan kode BbWS adalah yang terbaik dalam menghambat peletakan telur dan menekan persentase telur menetas WBC.

Abstract

Pardosa pseudoannulata and Menochilus sexmaculatus are two predators of the brown planthopper (BPH, Nilaparvata lugens, Hemiptera: Delphacidae) in rice fields. The research aimed to determine the predation and the competition model of P. pseudoannulata and M. sexmaculatus on different BPH densities. This study used a completely randomized design (CRD) factorially. The first factor was the difference in predator species (P. pseudoannulata, M. sexmaculatus, and a combination of predators P. pseudoannulata + M. sexmaculatus), and the second was the difference in N. lugens density (0, 30, 50, and 70 individuals). The treatment was repeated in 4 repetitions. The parameters observed were predatory and competitive behavior, predation rate, body weight gain, and competition model. The research showed that P.pseudoannulata was more aggressive in finding and catching prey than M. sexmaculatus. The more prey provided, the higher the predation rate of the two predators. The combination of them as joint predators has increased the pressure on BPH and the predation rate, although it was still below its potential. Sub-lethal competition occurred between the two predators; it did not affect P.pseudoannulata but affected the behavior and reduced body weight of M. sexmaculatus. The competition between the two predators was not influenced by BPH density but by the intensity of meeting time. Both as joint predators in rice fields are safe and beneficial for BPH control.

Abstract

Integrated Pest Management (IPM) is a pest control method that combines several control techniques by considering ecological, economic, and sociological consequences. Management efforts with IPM principles can be conducted by cultivating healthy plants and entomopathogen application. This study examined the IPM package's success for controlling fall armyworm (Spodoptera frugiperda) in maize field. This research was conducted in a farmer's maize plantation in the West Pasaman District from August to December 2021. The study used a Randomized Block Design (RBD) which consisted of three treatments and five replications. The treatments were different cultivation techniques using IPM, Non-IPM, and control. The variables observed were the population of S. frugiperda (individual/plant), attack rate (%), attack intensity (%), cob weight (g/cob), and farming cost (IDR). The results showed that the IPM and Non-IPM maize cultivation techniques had no different effect on S. frugiperda, especially survival stage, attack rate, intensity, and yield. However, this effect was higher than the control. In addition, the economic benefits of cultivation with IPM were higher than non-IPM. Therefore, this IPM package can be recommended for controlling S. frugiperda because it is also economically profitable and environmentally friendly.
