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

Infestation of major pests and diseases on various cassava clones in Lampung-Indonesia. Lampung Province is one ofcassava producers in Indonesia which contributes more than 30% to the total national cassava production. However, theinfestation of pests and diseases can limit cassava production in the field. The objective of this research was to observe theinfestation level of major plant pests and diseases of cassava in Lampung. A survey was conducted in August 2016 in severallocations of cassava fields owned by farmers and experimental plots in the area of Faculty of Agriculture, University ofLampung. The results showed that cassava mealybug (Phenacoccus manihoti), papaya mealybug (Paracoccus marginatus)and red mite (Tetranychus urticae) infested at cassava clones in Lampung. The infestation of red mite tended to be higher thanthat of mealybugs. The cassava brown leaf spot disease that infested in mild to moderate severity was found on all cassavaclones, while viral disease with prevalence of 78% was only found on Duwet 1 clone in experimental plot.

Abstract

Influence of Culture Medium on the Sporulation and Viability of Aspergillus spp. and Talaromyces spp. Entomopathogenic Fungi. The purpose of this study was to determine the effect of three kinds of cultures media on the spore production and viability of Aspergillus spp. (AS1, 6, 7, 9) and Talaromyces spp. (AS2?5, 8, 10) entomopathogenic fungi. This study was arranged using Factorial-Completely Randomized Design (CRD) with 2 factors and 3 replications. The first factor was three kinds of cultures media (potato dextrose agar (PDA), corn meal agar (CMA), and sabouraud dextrose agar (SDA)) and the second one was isolates of Aspergillus spp. Or Talaromyces spp.. Data of spore production and spore viability were tested using ANOVA and if there was significantly difference, the data then further analyzed using Tukey?s Honestly Significant Difference (HSD) test at 5% of significant level. The spore production of Aspergillus spp. were in the range of 0.58 - 14.27 x 108 spores mL-1 (PDA); 0.28 ? 2.68 x 108 spores mL-1 (SDA) and 1.85 - 5.33 x 108 spores mL-1 (CMA). The highest spore production was achieved by AS1 isolate that was grown on PDA media. The spore produced by Talaromyces spp. were in the range of 2.15 ? 28.62 x108 spores mL-1 (PDA); 0.28 ? 29.43 x108 spores mL-1 (SDA); and 1.88 ? 16.63 x108 spores mL-1 (CMA). The highest spore production was produced by AS8 isolate which were cultured on PDA. The spore viability among isolates of the two entomopathogenic fungi were not significantly different. The spore viability of Aspergillus spp. was in the range of 95.10 ? 97.66% (PDA), 94.02 ? 98.45% (SDA) and 92.86 ? 98.20% (CMA). The spore viability of Talaromyces spp. was in the range of 95.83 ? 100% (PDA), 85.83 ? 100% (SDA), and 90.75 ? 100% (CMA). Culture medium influenced spore production but not the spore viability. The best culture media used for spore production of both of the entomopathogenic fungi was PDA media.

Abstract

The Population of White-Bellied Planthoppers and their Natural Enemies: the New Pest of Corn in Lampung. The white-bellied planthoppers (Stenocranus pasificus), hereinafter referred to as WBP, as new exotic pests in Lampung have the poten-tial to reduce corn production and threaten national food sovereignty. Therefore, population of the pest needs to be managed to prevent the outbreaks. However, there is still limited information on the bio-ecology of WBP. Thus, this research was conducted to: 1) study the population growth pattern of WBP on various corn cultivars and 2) document the natural enemies of WBP. This research was carried out from May to December 2017with a survey method on several corn fields in South Lampung and planting trial on an experimental field of Faculty of Agriculture, Universitas Lampung planted with 3 corn cultivars, i.e. Madura, P-27 and NK which were arranged in randomized complete block design with three replications. The results of the research showed: 1) there were two peaks of population density observed during plant growth. The peak of adult stage of macroptera population density occurred at 17 and 53 days after planting (dap), the highest number of leaves with oviposition mass was observed at 24 and 65 dap, while the peak of population density of nymph stage and adult stage of brachiptera occurred at 31 and 75 dap; 2) Natural enemies of WBP included 9 orders, classified as specialist predators of mirid bugs (Cyrtorhynus) and rove beetles (Paederus), and generalist predators of spiders (Araneae) and lady beetles (Coccinellidae). The population of specialist predators was fluctuated depending on WBP population, while the population of generalist predators was varied.

Abstract

Diversity and abundance of nematodes in guava (Psidium guajava L.) cultivation in Lampung. Crystal guava agroecosystem is inhabited by many species of plant parasitic nematodes. However, information regarding this topic was still limited. This study aimed to understand the species dominancy of nematodes in crystal guava cultivation in Lampung. Sampling was carried out in three locations of guava crystal plantations: Lampung Timur, Lampung Tengah, and Tanggamus. The laboratory analysis was done at the Plant Pest Science Laboratory and Agricultural Biotechnology Laboratory, Universitas Lampung. The study was conducted in December 2019 – July 2020. Nematodes were identified to the level of the genus. The Prominance value (PV) was used to assess the nematodes genus dominancy. The results showed that the nematodes inhabiting the crystal guava agro-ecosystem in Lampung was both plant parasitic and free-living nematodes. The plant parasitic nematodes were identified as Meloidogyne, Aphelenchus, Hemicriconemoides, Tylenchus, Aphelenchoides, and Xiphinema, while free-living nematodes was Rhabditis, Dorylaimine, Dorylaimus, and Mononchus. The dominant plant parasitic nematode was Meloidogyne and the dominant free-living nematode was Rhabditis. The abundance of Meloidogyne /300 mL of soil was 351.47 individuals in Lampung Timur, 124.27 individuals in Lampung Tengah, and 82.18 individuals in Tanggamus. The dominant free-living nematode in the three locations was Rhabditis.

Abstract

Spodoptera frugiperda is an invasive pest that attacks maize throughout Indonesia. As an invasive pest, the population of S. frugiperda continues to increase exponentially, leading to outbreaks. Both internal factors (biology) and external factors (weather, host, and natural enemies) can affect the growth rate of pest populations. This research was conducted to assess the population dynamics of S. frugiperda based on the extent of its infestation and damage to maize post-invasion in Lampung Province. Observations were made in maize fields in 15 districts of Lampung Province from 2019 to 2022. Damage intensity was calculated based on the leaf damage scale. Weather data from 2019 to 2022 was obtained from the Lampung Province Central Statistics Agency. The research results indicate that upon the initial introduction of S. frugiperda to Lampung Province, the population increased exponentially, as observed based on the level of infestation and damage to maize. There was an outbreak from late 2019 to early 2020, and after that, there was a population decline. The population increase coincided with the early rainy season, which is associated with the beginning of the maize planting season. Although the level of damage to the maize is considered slight, S. frugiperda can cause anywhere between 21.94% to 51.38% of damage.

Abstract

This research aimed to study the efficacy of the fungus Purpureocillium lilacinum as a bionematicide to control root-knot nematodes (RKN). Two steps of experiments were carried out in this study. The first experiment involved the application of various levels of bionematicide doses to control RKN on tomato plants. The second experiment tested the application of bionematicide (both as a single application and in combination with bromelain compost) to control RKN on guava cv. Kristal. A carbofuran nematicide was applied following the company’s recommendation in this second experiment for comparison. The results of the first trial showed that the application of P. lilacinum bionematicide at doses ranging from 20–40 g per plant or 7–13 g per kg of soil was effective in reducing the J-2 RKN population in the soil and roots, as well as mitigating damage to plant roots. In the second experiment, it was shown that the application of P. lilacinum bionematicide, either alone or mixed with bromelain compost, was more effective than the application of carbofuran nematicide in reducing the J-2 RKN population in the soil and roots, as well as in minimizing root damage to guava seedlings. Additionally, the application of bionematicides mixed with compost proved more effective than their single application in reducing plant root damage. Furthermore, apart from being able to control nematode populations and plant damage, P. lilacinum bionematicide could stimulate plant growth.
