| residual concentrations of propanil, tcab, and other pesticides in rice-growing of soils in the united states, 1972. | ninety-nine soil samples from the rice-growing states of arkansas, california, louisiana, mississippi, and texas were collected, primarily to monitor the herbicide propanil. no residual concentrations of propanil were detected in any of these samples, but tcab, a propanil transformation product, was detected in six samples at concentrations ranging from 0.01 ppm to 0.05 ppm. organochlorine and organphosphorus pesticide determinations were also performed. the compounds dieldrin, aldrin, and ddt a ... | 1980 | 7422467 |
| nutritionally important starch fractions of rice cultivars grown in southern united states. | dietary starches can be classified into 3 major fractions according to in vitro digestibility as rapidly digestible (rds), slowly digestible (sds), and resistant starch (rs). literature indicates that sds and/or rs have significant implications on human health, particularly glucose metabolism, diabetes management, colon cancer prevention, mental performance, and satiety. in this study, the nutritionally important starch fractions (rds, sds, and rs) in cooked rice were assayed in vitro, making us ... | 2010 | 20629878 |
| mapping qtl main and interaction influences on milling quality in elite us rice germplasm. | rice (oryza sativa l.) head-rice yield (hr) is a key export and domestic quality trait whose genetic control is poorly understood. with the goal of identifying genomic regions influencing hr, quantitative-trait-locus (qtl) mapping was carried out for quality-related traits in recombinant inbred lines (rils) derived from crosses of common parent cypress, a high-hr us japonica cultivar, with rt0034, a low-hr indica line (129 rils) and lagrue, a low-hr japonica cultivar (298 rils), grown in two us ... | 2011 | 20857082 |
| predicting economic losses from the continued spread of the mexican rice borer (lepidoptera: crambidae). | the mexican rice borer, eoreuma loftini (dyar) (lepidoptera: crambidae), is an invasive species that originated from mexico, and it is threatening to cause major economic losses to sugarcane, saccharum spp., and rice, oryza sativa l., industries in louisiana. the insect is expected to reach sugarcane and rice production areas in louisiana by 2008, and infest all of louisiana sugarcane and rice industries by 2035. when all sugarcane in louisiana becomes infested, annual yield losses of $220 milli ... | 2008 | 18459384 |
| expansion of the mexican rice borer (lepidoptera: crambidae) into rice and sugarcane in louisiana. | the mexican rice borer, eoreuma loftini (dyar) (lepidoptera: crambidae), is an invasive pest of sugarcane, saccharum spp., rice, oryza sativa l., and other graminaceous crops in the gulf coast region of the united states. traps baited with e. loftini female sex pheromones were used to document establishment and distribution of e. loftini near sugarcane, rice, and noncrop hosts in seven southwest louisiana parishes from 2009 to 2013. additional field surveys documented larval infestations in comm ... | 2015 | 26313982 |
| the active space of mexican rice borer pheromone traps. | the mexican rice borer, eoreuma loftini (dyar) (lepidoptera: crambidae), is an invasive pest of sugarcane, saccharum spp., rice, oryza sativa l., and other graminaceous crops in the united states. traps baited with the synthetic female sex pheromone of e. loftini are used for monitoring and management of this invasive pest. however, the active space, or radius of attraction, of these traps is not known. two field experiments examined the effect of intertrap distance on trap captures with hexagon ... | 2016 | 27665613 |
| monitoring mexican rice borer (lepidoptera: crambidae) populations in sugarcane and rice with conventional and electronic pheromone traps. | the mexican rice borer, eoreuma loftini (dyar), is a major pest of sugarcane, saccharum spp., rice, oryza sativa l., and other graminaceous crops in texas and louisiana. the ability of conventional and electronic pheromone traps to monitor e. loftini in sugarcane and rice habitats was evaluated in two separate 2-yr field studies. bucket traps baited with a synthetic female sex pheromone monitored e. loftini populations in commercial sugarcane fields in calcasieu and jefferson davis parishes thro ... | 2017 | 28053210 |
| population distribution and range expansion of the invasive mexican rice borer (lepidoptera: crambidae) in louisiana. | the mexican rice borer, eoreuma loftini (dyar) (lepidoptera: crambidae), is an invasive pest that was first introduced into southern texas in 1980 and has been expanding its range eastward along the united states gulf coast. the pest attacks rice (oryza sativa l.), sugarcane (saccharum spp.), corn (zea mays l.), and other graminaceous crops, and its establishment in louisiana is expected to have severe economic impacts on crop production. range expansion and population distribution of e. loftini ... | 2017 | 28334259 |
| oviposition behavior of diatraea saccharalis (lepidoptera: crambidae) on different rice cultivars in louisiana. | the sugarcane borer, diatraea saccharalis (f.), is a pest of a variety of graminaceous crops in the southern united states, including sugarcane, maize, and rice in louisiana. this study examined several aspects of d. saccharalis oviposition behavior on rice (oryza sativa). the vertical distribution of egg masses on four phenological stages of rice in the field showed that d. saccharalis prefers to oviposit on the uppermost portions of rice plants, regardless of plant stage. in greenhouse choice ... | 2012 | 22732615 |
| impacts of seeding rate on interactions between rice and rice water weevils. | the rice water weevil, lissorhoptrus oryzophilus kuschel, is the most widely distributed and destructive early season insect pest of rice, oryza sativa l., in the united states. economic losses result primarily from feeding by the larval stage of this insect on the roots of flooded rice plants. prior studies suggest that infestations of rice water weevil larvae are more severe at low plant densities. moreover, because feeding by the rice water weevil reduces rice plant tillering, a process parti ... | 2009 | 19886448 |
