Abstract

The Community of Nematode in The Young Coffee ( Coffea Canephora Var. Robusta ) Crops in Tanggamus District, Lampung. Tanggamus district is one of coffee production center in Lampung province. Since year of 2013, farmers in Tanggamus have been replaced the unproductive old coffee by coffee seed introduced from East Java. Introducing coffe seed from outside area at risk of carrying plant parasitic nematodes. The purpose of this research was to study community of nematode associated with young coffee crops in Tanggamus. Survey was conducted in coffee robusta (Coffea canephora var. robusta) fields belonging to farmer on September 2014. Soil samples were collected from three sites: Margo Mulyo, Sumber Rejo and Batu Bedil. Nematodes were extracted by sieving and centrifugation with sugar solution method. The results show that were 20 genera consisted of 9 genera of plant parasitic and 11 genera of free living nematodes associated with young coffee in Tanggamus. The nematode community was dominated by Pratylenchus and Radopholus. The population of Pratylenchus and Radopholus in Sumber Rejo site were 421 and 846 individual per 300 ml of soil respectively. It was needed to indentify up to species taxonomic level for Pratylenchus and Radopholus associated with young coffee in Tanggamus.

Abstract

Crop losses due to phytonematodes infection commonly occurred on intensive plantation practiced for a long time. The research was aimed to study phytonematodes status on several age-different plantation of Cavendish banana in PT NTF Way Kambas, Lampung. Soil and root samples were taken from three different plantations, selected based on time period of cultivation practice, i.e. 3?5, 10?12, and 17?19 years long. The modification of Baermann funnel method was applied to collect nematodes. The status of phytonematodes were determined based on the absolute frequency (AF), relative frequency (RF), and absolute population (AP) of each genus. The results showed that 13 phytonematodes genera inhabited Cavendish banana crops. Pratylenchus and Radopholus have important status on a land that had been cultivated for 3?5 and 10?12 years with AF 100%, RF 31%, and  AP 298.8, and 423.0  individues per 200 mL of soil, respectively on 3?5 years long lands, and AF100%, RF 39% and PA 215, and 126 individues per 200 mL of soil, respectively on 10?12 years long lands. Pratylenchus and Radopholus were less important on 17?19 years long rotated lands with AF 77%, RF 22% and AP 33.0 and 16.4 individues per 200 mL of soil respectively. The status of other phytonematodes were not important with low value of AF, RF, and AP.

Abstract

Population outbreak of the oriental migratory locust, Locusta migratoria manilensis Meyen (Orthoptera: Aciridae), in Lampung between 1990’s to 2000’s has caused serious economic loss to agriculture.  Anticipation of the pest outbreak is required to prevent serious loss in the future; one of possible approach is by analyzing data of rainfall and locust damage area. The study was aimed to analyze the relationship between rainfalls and area of damage caused by locust population in rice and corn fields using 17 years period of data from Lampung Province.  The results indicate that locust damage occurred when there were high rainfalls followed low ones at wet season. Time lag of 8 month was determined as the period needed for L. migratoria manilensis to raise its population when the pest has developed gregarious colonies in the region.  Rainfalls between 248,27 mm/month (on corn fields) to 287,06 mm/month (on rice fields) were optimum for the initiation of the locust population increase after a period of dry weather in the region.  Results of autocorrelation tests indicate that the occurrence of locust damage in an area would be followed by population increase in a region where gregarious colonies have developed.

Abstract

This study was aimed to show whether conservation effort through reduced tillage or mulching can promote soil zoological benefits, especially to the soil arthropods in sugarcane plantations area, Central Lampung, Indonesia. Twenty sugarcane plots of 25 m × 25 m size each were prepared in the area and treated with two combined treatments i.e. tillage (no tillage and full tillage) and mulching (without bagasse and with bagasse mulch). Tillage and planting were done in July 2010 while mulching was conducted in August 2010. The arthropods were sampled using pitfall traps (mouth diameter = 13.5 cm), each was set per plot for 24 hours. Specimens were identified at least to order level. Sampling was done in September 2010 (1 month after mulch treatment, MAT), January 2011 (4 MAT), and July 2011 (10 MAT). We found four major arthropod orders, namely Araneae (spiders, predator), Coleoptera (beetles, mostly non predator), Collembola (springtails, fungal feeder), and Hymenoptera (ants, mostly forager). The last two groups were the most dominant (contributing to > 90 % of the total abundance). Tillage affected the abundance of overall soil arthropods at 1 MAT and 4 MAT but the effect disappeared at 10 MAT. Reduced tillage can conserve, or does not harm, some soil arthropod groups (ants, predatory ants, beetles, springtails, spiders) in sugarcane agroecosystem.

Abstract

The soil nematode diversity in several land-use types in Way Kanan ASB-Benchmark Area.  The conversion  of forest to intensive agroecosystem such as monoculture system reduces biodiversity of the plant, herbivore, and decomposer subsystems.   Those changes affected  the litter and plant root quality.  Consequently, few soil nematode species could be dominant and cause of disturbance of the stability of the below ground  community.   The increasing  populations of plant parasitic nematodes usually occur on monoculture system .   The research was conducted to study the effect of forest changes in several land use types on soil nematode diversity in Way Kanan Benchmark Area.  Soil sampling on five land use types (secondary forest,  agroforest or tree based agriculture, plantation, cassava field, and Imperata grass land) was conducted in November1996 and December 1997.   Nematodes  were extracted by decantation-centrifugation with sugar method.  The soil  nematodes were grouped into order and generic level including plant parasitic and  non- parasitic. The results show that the order of  Rhabditida, Dorylaimida, and Tylenchida were found from  those five land-use types.  The total genera of  plant parasitic nematodes in Imperata grass land were the highest among the other four land use types.  The total number of  non-plant parasitic nematodes in secondary forest (28.0 individual per 300 cc of soil) was higher than total number in the plantation ( 2.6 individual per 300 cc of soil), cassava field (4.0 individual per 300 cc of soil) or Imperata grass land (6.6 individual per 300 cc of soil).  The total number of  plant parasitic nematodes in Imperata grass land (59.8 individual per 300 cc of soil), agroforest (59.0 individual per 300 cc of soil), secondary forest (48.2 individual per 300 cc of soil), and  plantation (17.6 individual per 300 cc of soil) were not significantly different, but  total number in Imperata grass land and  agroforest  were significantly  higher than that in cassava field (11,6 individual per 300 cc of soil).

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

Penelitian ini bertujuan untuk mempelajari keragaman dan kelimpahan nematoda parasit tumbuhan akibat perlakuan sistem pengolahan tanah dan pemulsaan pada pertanaman tebu periode ratoon I. Penelitian dilaksanakan di lahan pertanaman tebu milik PT Gunung Madu Plantations dari April sampai dengan September 2012. Satuan percobaan berupa petak 25 m x 40 m dirancang menggunakan rancangan petak terbagi (split plot design) dengan sistem olah tanah sebagai petak utama dan pemulsaan sebagai anak petak, dengan lima ulangan (kelompok). Sistem olah tanah terdiri dari dua taraf, yaitu tanpa olah tanah dan olah tanah intensif. Pemulsaan terdiri dari 2 taraf, yaitu pemberian mulsa bagas 80 ton ha-1 dan tanpa mulsa. Sampel tanah diambil ketika tebu berumur 8 bulan dan 11 bulan, nematoda diekstraksi menggunakan metode penyaringan dan sentrifugasi menggunakan larutan gula dan diidentifikasi sampai pada tingkat genus berdasarkan ciri morfologinya. Hasil penelitian menunjukkan bahwa di lahan PT GMP ditemukan 34 genus nematoda dalam 6 ordo pada pertanaman tebu ratoonI. Jumlah genus dan indeks keragaman Shannon nematoda pada pertanaman tebu ratoon I tidak dipengaruhi oleh sistem olah tanah dan pemulsaan. Indeks keragaman Simpson nematoda pada pertanaman tebu ratoon I dengan perlakuan sistem olah tanah intensif tanpa pemulsaan lebih tinggi dibandingkan pada sistem tanpa olah tanah tanpa pemulsaan. Kelimpahan nematoda parasit tumbuhan pada pertanaman tebu ratoon I tidak dipengaruhi oleh perlakuan olah tanah dan pemulsaan. Kelimpahan nematoda parasit tumbuhan pada tebu ratoon I ketika umur 11 bulan lebih rendah daripada ketika umur 8 bulan.
