Taxonomy And Systematics Of New Zealand Faronitae (Coleoptera: Staphylinidae: Pselaphinae), Jong-Seok Park
Taxonomy And Systematics Of New Zealand Faronitae (Coleoptera: Staphylinidae: Pselaphinae), Jong-Seok Park
LSU Doctoral Dissertations
The New Zealand Faronitae was revised at the species level, and a phylogenetic study was performed based on morphological and molecular data. Eight new genera and 143 new species were discovered. Three new genera, “Brounea”, “Ahnea” and “Pseudoexeirarthra” were designated based on the species originally described in the genus Sagola. Five new genera, “Aucklandea”, “Chandlerea”, “Nunnea”, “Leschenea” and “Pseudostenosagola” were designated by new species. Three known genera, Exeirarthra, Stenosagola and Sagola were also revised at species level. Eighty four names were synonymized, two in Exeirarthra, four in Stenosagola and 78 in Sagola. Lectotypes of seven species, Sagola terricola Broun, S. …
Development Of Integrated Pest Management For Sugarcane Borer, Diatraea Saccharalis In Rice, Jaspreet Kaur Sidhu
Development Of Integrated Pest Management For Sugarcane Borer, Diatraea Saccharalis In Rice, Jaspreet Kaur Sidhu
LSU Doctoral Dissertations
Rice is grown over an area of approximately 500,000 acres in Louisiana. The lepidopteran stem borer complex attacking rice in the southern U.S includes stalk borer Chilo plejadellus Zincken, sugarcane borer (SCB) Diatraea saccharalis (F.) and Mexican rice borer, Eoreuma loftini Dyar. With the increasing impact of stem borers in Louisiana, an urgent need exists to develop strategies for management. Currently, no IPM program is in place for stem borers in Louisiana rice and research has been initiated to develop an IPM program for these pests. The first objective of this research was focused on host plant resistance. For this …
A Survey Of Chemical Elicitors And Their Effectiveness As Promoters Of Plant Defense Against Herbivory By Spodoptera Frugiperda (Smith) (Lepidoptera: Noctuidae), John Gordy
LSU Master's Theses
Insect herbivores can induce a range of plant defenses. Signal pathways can be activated that result in the production of secondary metabolites. Many of these compounds can reduce insect fitness, deter feeding, and attract beneficial insects. Additionally, organic and inorganic chemicals applied as a foliar spray or soil drench can activate these plant responses. Azelaic acid, benzothiadiazole (BTH), gibberellic acid (GA3), harpin, and jasmonic acid (JA) are thought to mediate plant response to pathogens and herbivores. The effects of these elicitors on the induction of plant defenses were determined by measuring the weight gain of fall armyworm (FAW), Spodoptera frugiperda …
Effects Of Caste On The Constitutive And Induced Expression Of Genes Associated With Immunity And Detoxification In Formosan Subterranean Termites, Dawn M. Simms
LSU Master's Theses
Simms, Dawn M., B.S., Louisiana State University, 1997 Master of Science, Spring Commencement, 2013 Major: Entomology Effects of Caste on the Constitutive and Induced Expression of Genes Associated with Immunity and Detoxification in Formosan Subterranean Termites Thesis directed by Associate Professor Claudia Husseneder Pages in thesis, 74. Words in abstract, 268. ABSTRACT Formosan subterranean termites (FSTs) live in dense populations and nest conditions that are conducive to microbial growth. Furthermore, termites are exposed to potential toxic substances in the soil and in their lignocellulose diet. These characteristics, in combination with the specialized caste system of FSTs, make this termite a …
