Abstract Sampling techniques currently used to determine control measures for the Coffee Berry-borer (CBB) are time-consuming and allow grower only a small window of opportunity select other options. Experiments were conducted in four coffee fields between 2005 2007 using IAPAR® traps that baited with ethanol methanol (1 : 3 ratio) benzaldehyde at 1% volume, test correlation number captured adults infestation levels CBB, action threshold level. For this study, density 20 traps/ha was each...
Opsiphanes invirae (Lepidopera: Nymphalidae) is a common pest of the African oil palm tree (Elaeis guineensis) in Brazil. Dead larvae were collected canopy trees cultivated amazon region (Para State) and analyzed for viral infection. Electron microscopy caterpillar extracts showed an icosahedral picorna-like virus particle with 30nm diameter. Total RNA extracted from partially purified particles was sequenced. A contig 10,083 nucleotides (nt) identified to encode one single predicted...
In this work, we evaluated the spatial and temporal distribution of Opsiphanes invirae larvae (Lepidoptera: Nymphalidae) in oil palm plantations state Pará, where 14 samplings were accomplished from April 2008 to August 2014. The experimental area consisted 3,582 ha splitted into 89 subareas 50 80 each. was determined by sampling number 10% plants (sample unit) each subarea, which obtained variable value (number / plant) coordinates (latitude longitude). variability dependence analysis made...
The Rhynchophorus palmarum insect is the main vector of nematode Bursaphelenchus cocophilus, causal agent red ring disease which carries a high mortality rate oil palms.The study aimed to check for spatial dependence and best way distribute traps in field control R. using geostatistical tools.The trial courts were georeferenced seeking maximum precision this perimeter plants that comprise it.The amount insects caught was affected by variation rainfall, increasing months greatest drought...
Abstract The coffee berry borer (CBB), Hypothenemus hampei Ferrari (Coleoptera: Curculionidae), is the most important pest in of growing countries. CBB females leave old dry berries after harvest and search for noninfested on plant or ground to lay eggs use as refuge until new are available trees following season. infestation level emergence from plants were evaluated two fields post-harvest Spring Brazil over seasons. Twenty infested separate cages (250 ml plastic cups) placed under tree...
The oil palm is an economically important crop cultivated in the North of Brazil. Damage caused by insects one main causes reduced productivity for palm. Before this research, only beetles family Curculionidae were considered to be pests However, first time, we report on damage a giant rhinoceros beetle plantations Pará, was identified as Golofa claviger (Linnaeus, 1771), which has single record Brazil (Pará) but widely distributed South America. species occurs unprecedentedly high abundance...
ABSTRACT: This study validated the use of leaf 17 on sampling Opsiphanes invirae Hübner (Lepidoptera: Nymphalidae) through quantification caterpillar abundance different spirals leaves, in comparison to 17, and, apical, intermediate and basal regions. was performed state Pará, between March-2014 March-2015. Results confirmed that is most adequate method for monitoring this defoliator pest.
This work studied the spatial dispersion of cases fatal yellowing (FY) in an oil palm plantation Acará, Pará State, Brazil. Data were collected monthly from two areas, divided 16 quadrants each, for a 24 month period (2012-2013). In each quadrant, 138 plants evaluated. The number diseased was counted twenty planting lines, and pattern disease analyzed. following analysis techniques used: common sequences “runs”, “doublets” quadrants. We also determined levels aggregation sectors. Plants with...
Objetivo: O estudo investigou os atributos biológicos, químicos e granulométricos do solo a incidência Amarelecimento Fatal (AF) na palma de óleo. Referencial Teórico: AF ataca inicialmente o sistema radicular da planta, degradando as raízes mais finas. Fatores abióticos, como topografia excesso água, estão associados à sua incidência. Disfunções metabólicas deficiências nutricionais nas plantas também podem contribuir para desenvolvimento doença. Método: Foi aplicada uma abordagem...
Abstract The aim of this work was to evaluate the spatial and temporal distribution males females R. palmarum using geostatistics as a tool. experiment carried out in commercial oil palm plantation area, municipality Moju (PA), Brazil. Monthly samplings were performed, from June 2013 May 2014. sampling insects through bucket-type traps with pheromone food attractant, all georeferenced. Population fluctuation, Pearson correlation analysis performed geostatistics. Among abiotic factors...
The objective of this study was to evaluate the attractiveness and food consumption Opsiphanes invirae by folioles different genotypes palm oil. Choice no-choice tests were performed using newly hatchet larvae O. aged 12 days. Five used, such as Deli × LaMe, Compact Ekona, Nigeria, Ghana, planted in 2008. In choice test, preferred Ekona at 3, 5 30 minutes with insects size 1.70, 2.20, 0.60, respectively, Ghana 48 72 hours sized 0.80 1.10, after release caterpillars, while Nigeria less...
The oil palm seedling production system is one of the stages with highest cost due to long nursery period and high use chemical fertilizers. In this context, insertion rhizobacteria appears as a technology that can reduce average production. objective was study economic efficiency seedlings, function inoculation Bacillus amyloliquefaciens UFRAB01, compared conventional synthetic showed adoption allowed reduction 11.04% in each produced. seedlings microbial economically viable, it allows...
Automeris liberia Cramer are found in South America, with documented sightings Ecuador, Peru, some regions of Mexico and, more recently, the Brazilian Amazon. These moths cause damage to several plant species. We designed an experiment study biology and morphometry A. laboratory provide information for management pest oil palm cultivation Caterpillars rearing were collected from commercial areas cultivation, where they defoliation plant. They fed a natural diet leaves Tenera variety observed...
