Abstract

Salah satu OPT yang sering menyerang dan menurunkan produksicabai merah adalah lalat buah. Penelitian ini bertujuan untuk mengetahui pengaruh warna pada papan perangkap dan pemberian jus buah terhadap jumlah tangkapan perangkap likat. Pemasangan perangkap likat dilaksanakan pada bulan Januari - Juni 2017 di Desa Candra Kencana, Kecamatan Tulang Bawang Tengah, Kabupaten Tulang Bawang Barat.Identifikasi serangga yang tertangkap di lakukan di Laboratorium Ilmu Hama Tumbuhan, Fakultas Pertanian, Universitas Lampung. Satuan Percobaan disusun dalam rancangan acak kelompok faktorial dengan 2 faktor (3 x 3) dengan 5 ulangan. Faktor I adalah jus yang terdiri dari 3 taraf : tanpa jus, jus jambu biji, dan jus belimbing. Faktor II adalah warna 3 taraf : tanpa warna (bening), warna hijau, dan warna kuning. Perangkap dipasang saat tanaman cabai mulai berbuah yaitu pada umur 12 minggu setelah tanam. Hasil penelitian ini menunjukkan bahwa penggunaanwarna kuning pada papan likat memberikan jumlah tangkapan yang lebih tinggi daripada warna lainnya. Penambahan jus belimbing pada perangkap likat menghasilkan jumlah tangkapan yang lebih tinggi dibandingkan jus lainnya. Kombinasi perangkap likat warna kuning dengan penambahan jus buah belimbing menghasilkan jumlah tangkapan lebih tinggi daripadakombinasi warna dan jus buah lainnya.

Abstract

Impact of Permethrin-Insecticide Application on Mirid Pest of Cocoa Helopeltis spp. (Hemiptera: Miridae) and on Non-target  Arthropods in Cocoa Plantations (Theobroma cacao L.). Cocoa mirid bugs, Helopeltis spp., (Hemiptera: Miridae) are the most important pest of cocoa in Indonesia. A field study was conducted to investigate the effect of permethrin on cocoa mirids and non-target arthropods at a cocoa plantation in specific place. A randomized complete block design was used in which each of four blocks consisted of 5 treatments (4 concentrations of permethrin; 50; 100; 200; and 250 ppm and control). The results indicated that the application of permethrin significantly increased the cocoa mirids mortaliiy throughout all sprayed cocoa trees (up to 100% 72 h after application). Even at 1 h after application, the percentage of Cocoa mirids mortality 29.2% - 53.9%) on cocoa trees sprayed with permethrin at concentrations of 50 - 250 ppm was significantly higher than that on control plant (3.6%). At 72 h after treatments, application of permethrin at concentrations of 200 and 250 ppm caused a complete kill (mortalty of 100%) in the test mirids. Meanwhile, ground cloths caught at least 22 fanilies of abore-ground arthropods that were found killed by permethrin applications. Moreover, the number of non-target arthropods killed by permethrin at concentrations of 100 - 250 ppm (27.3 - 85.3 individuals/ground cloth) were signifcantly higher than that on control trees. These results demonstrated that despite high efficacy of permethrin in controlling of cocoa mirids (Hetopeltis spp.), its application also had adverse effects on non-target arthropods incocoa plantations.

Abstract

Laboratory bioassays were conducted to compare the effects of the leaf extract of Acalypha indica  L. (Euphorbiaceae) with synthetic insect growth regulators (IGRs) triflumuron and buprofezin against Spodoptera litura (F.). The experiment was set up as a randomized complete block design (RCBD). The treatments were two concentrations of  A. indica extracts 1000 and 2000 ppm, two concentrations of  buprofezin 100 and 200 ppm, two  concentrations of triflumuron 120 and 240 ppm and control. Each treatment was replicated three times. Second instar larva of  S. litura  were used for the bioassays.  Mortality and biological variables of treated and control larvae were recorded daily. The results indicated that the application of A. indica extracts  and synthetic IGRs (buprofezin & triflumuron) significantly caused the S. litura  mortality throughout the experimental period. At first, the toxicity of triflumuron on larval S. litura was significantly higher compared to those of buprofezin and Acalypha indica leaf extract. However, at the end of experimental period all treatments caused high mortality on S. litura, and those all were significantly different from control. The treatments also caused abnorrmal growth in larval, pupal, and adult stages. While in the control, larvae molted into normal adults. The results indicated that the use of biorational control agents such as synthetic insect growth regulators (IGRs) and those based on naturally derived products such as botanical insecticides show promise as a potential tool in S. litura management programs.

Abstract

The field and laboratory experimental studies were conducted to determine the phosphorus (P) adsorption behavior employing Langmuir Method and yield of sugarcane as affected by compost and inorganic fertilizer applications, and to determine the correlations between the Langmuir parameters and the availability of P in soil or harvested P by the sugarcane. Both field and lab experiments were arranged in a randomized block design, consisting of five treatments (A= 100% NPK, B=100% compost, C=100% NPK + 50% compost, D= 50% NPK + 100%, compost, and E= no fertilizer).  Each treatment was replicated three times. Field and laboratory studies were carried out in the sugarcane field and in the Laboratory of Soil Science, the University of Lampung for Langmuir P studies, respectively. The results showed that the applications of 100% NPK plus 50% organic fertilizer, and 100% NPK resulted in the highest amount of available-P in the soil, the lowest maximum adsorption of P (Xm) and the lowest relative bonding energy of P (km); as well as the highest effect on the increase of sugarcane production. On the other hand, the treatments of no fertilizer and the 100% organic fertilizer resulted in the highest maximum adsorption of P (Xm) and the lowest sugar production. There were very significant negative correlations between the maximum adsorption of P (Xm) and soil P, harvested P by the sugarcane and stem biomass; while similar trend but no significant correlations between the relative bonding energy of P (km) and soil P, harvested P, leaf biomass and stem biomass were detected.

Abstract

Ground-dwelling arthropods play many important roles in agroecosystems. This experiment was conducted to assess the effects of botanical and synthetic insecticides on soil arthropods in edamame crops. The study included six treatments: soursop leaf extract at concentrations of 1% and 2%, diflubenzuron at concentrations of 0.05% and 0.1%, a common synthetic insecticide (chlorantraniliprole 0.15%), and a control (untreated plants), each with three replications. Pitfall traps were used to sample soil arthropods. A total of 2222 soil arthropods were collected, consisting of 1443 (64.94%) predatory arthropods and 778 (35.06%) detritivorous arthropods. The dominant orders of predators and detritivores were Araneae (61.5%) and Coleoptera (40.2%), respectively. The highest numbers of predatory and detritivorous arthropods were found on edamame plants sprayed with soursop extract, while the lowest numbers were recorded on plants treated with the common synthetic insecticide chlorantraniliprole. These results indicate that chlorantraniliprole negatively impacts the presence of ground-dwelling arthropods in edamame agroecosystems. In contrast, the application of the botanical insecticide (soursop leaf extract) and the synthetic insect growth regulator (diflubenzuron) did not reduce the abundance or diversity of ground-dwelling arthropods in edamame fields.

Abstract

The purpose of this study was to find out the growth of Beauveria bassiana fungal colonies in vitro on PSA media and to find out the pathogenicity of B. bassiana fungus against Strepsicrates rhothia larvae. The experiment was conducted using a Randomized Complete Block Design (RCBD), comprising five treatment levels of B. bassiana spore density: 7.1 × 10⁴, 7.1 × 10⁵, 7.1 × 10⁶, 7.1 × 10⁷ conidia/mL, and without B. bassiana as control. Each treatment was replicated three times. The results showed that the average growth of B. bassiana fungus two weeks after inoculation was 3.9 cm. The number of spores of B. bassiana fungus at dilutions of 10-1, 10-2, 10-3, and 10-4 was 7.1 x 107, 7.1 x106, 7.1 x 105, and 7.1x 104 conidia/mL, respectively. After 24 hours of incubation, the viability of B. bassiana spores reached 86.04% and at a spore concentration of 7.1 × 10⁷ conidia/mL, B. bassiana resulting in 100% mortality of S. rhothia larvae.
