Although oceanic transform faults (OTFs) are ubiquitous plate boundaries, the geological processes occurring along these systems remain underexplored. The Gofar OTF of East Pacific Rise has gained attention due to its predictable, yet enigmatic, earthquake cycle. Here, we present results from first ever controlled-source electromagnetic survey an OTF, which sampled Gofar. We find that fault is characterized by a subvertical conductor, extends into lower crust and thus implies deep fluid...
The Mexican rice borer, Eoreuma loftini (Dyar), is native to Mexico, and has been reported in the states of Baja California, Colima, Hustecas, Jalisco, Michoacan, Nayarit, Nuevo Leon, Oaxaca, San Luis Potosi, Sinaloa, Sonora, Tamaulipas, Veracruz, Yucatan (Morill 1925; Van Zwaluwenburg 1926; Riess 1981; Johnson 1984; Rodriguez-del-Bosque et al. 1989; ReayJones 2007). Eoreuma. was originally described by Dyar (1917) as a member genus Chilo Zincken from specimen collected Arizona, U.S.A....
Female Homalodisca coagulata (Say) were collected from October 2001 to February 2005 citrus at the University of California, Riverside. Between 5 and 20 females per sampling date dissected, each was assigned an ovarian rank: previtellogenic, vitellogenic, or postvitellogenic. Ovarian ranking used characterize H. reproductive activity. Results these dissections revealed consistent annual patterns in proportion previtellogenic present this field population. These indicate that there are two...
The anatomy and histology of female Homalodisca coagulata (Say) (Hemiptera: Cicadellida: Proconiini) reproductive organs is described using light microscopy. H. consist one pair ovaries, each with 10 telotrophic ovarioles, a lateral oviducts, common oviduct, spermatheca, an enlarged genital duct, complex bursa copulatrix, vagina, two types accessory glands, chamber. follow the general pattern seen in cicadellids. important copulation sperm transfer, described. A set morphological criteria...
The rice stink bug, Oebalus pugnax (F.) (Hemiptera: Pentatomidae), is an economically important late-season pest of in the southern United States. Stink bug feeding results yield reduction and discounted purchase price due to broken or discolored ("pecky") grains. primary tactic for O. management application insecticides once adults reach action threshold. Recent surveys show that pyrethroids are preferred by U.S. farmers over all other reduce densities. However, preliminary tests 2009...
The sugarcane borer, Diatraea saccharalis (F.), is a pest of variety graminaceous crops in the southern United States, including sugarcane, maize, and rice Louisiana. This study examined several aspects D. oviposition behavior on (Oryza sativa). vertical distribution egg masses four phenological stages field showed that prefers to oviposit uppermost portions plants, regardless plant stage. In greenhouse choice experiments, females strongly preferred plants at boot panicle differentiation...
The Asian citrus psyllid, Diaphorina citri Kuwayama, was detected in Orleans Parish, LA, May 2008. Soon after detection, the tree upon which psyllid had been found tested positive for greening (or huanglongbing). In response to these detections, personnel from Louisiana State University AgCenter worked with representatives of Department Agriculture and Forestry USDA-APHIS-PPQ respond situation. Pest control recommendations were developed nursery, commercial, backyard production. This...
A binomial sampling method for the potato aphid, Macrosiphum euphorbiae (Thomas), on processing tomato plants, Lycopersicon esculentum (Mill), is proposed. Relationships between mean number of M. per leaf and proportion leaves infested [P(I)] with both upper interior varieties ‘Alta’ ‘Halley’ are presented. split-plot design was used variety, position in plant canopy, block as factors examined through linear regression analysis variance (ANOVA). Results supported hypotheses that densities...
The “All about Blueberries” Community of Practice is adapting the best existing extension publications and developing new research-based recommendations related to blueberry production consumption. Our primary goal increase productivity consumption blueberries, initially in southeast then nationwide. experts that are members our located southeastern United States (Alabama, Louisiana, Mississippi, North Carolina) where both southern highbush rabbiteye blueberries grown. Southern states with...
