Identifying The Components Of A Hemp (Cannabis Sativa L.) (Rosales: Cannabaceae) Integrated Pest Management Program In Louisiana, Nathan C. Arey Jul 2022

Identifying The Components Of A Hemp (Cannabis Sativa L.) (Rosales: Cannabaceae) Integrated Pest Management Program In Louisiana, Nathan C. Arey

LSU Master's Theses

Hemp, Cannabis sativa (L.) (Rosales: Cannabaceae), is defined as a plant in the genus Cannabis with a delta-9 3 tetrahydrocannabinol (THC) concentration of not more than 0.3% on a dry weight basis. Domestic acreage of this crop has increased in response to the ratification of the Agricultural Act of 2014 and the Agricultural Improvement Act of 2018. In 2021, 21,915 hectares of hemp were planted in the United States with a production value of $712 million. There is a current lack of literature on insect related research in this reemerging crop system in the state of Louisiana. Therefore, this present …


Re-Evaluation Of Late Season Action Thresholds And The Effect Of Seed Treatments On Early Season Colonization Of Threecornered Alfalfa Hopper, Spissistilus Festinus (Say), In Louisiana Soybean, Glycine Max (L) Merr, Tyler Ray Tagle Musgrove Apr 2022

Re-Evaluation Of Late Season Action Thresholds And The Effect Of Seed Treatments On Early Season Colonization Of Threecornered Alfalfa Hopper, Spissistilus Festinus (Say), In Louisiana Soybean, Glycine Max (L) Merr, Tyler Ray Tagle Musgrove

LSU Master's Theses

Soybean, Glycine max (L.) Merr, is considered the most economically important oil and feed crop in the US and is grown on nearly 35,000,000 ha on an annual basis. Factors that limit yield include weed pressure, disease infection, and of particular interest to entomologists, insect herbivory. Soybean is targeted by a range of above and below ground pests which are primarily controlled by insecticides. Neonicotinoids are a recently popularized insecticide class that when applied as a seed treatment, can provide protection from early season pests. The most economically significant early season pest is threecornered alfalfa hopper, Spissistilus festinus (Say), whose …


Effects Of Elicitor Induced Host Plant Resistance On Lepidopteran Insecticide Efficacy, Abigail Cox Aug 2017

Effects Of Elicitor Induced Host Plant Resistance On Lepidopteran Insecticide Efficacy, Abigail Cox

LSU Master's Theses

Soybean looper (SBL), Chrysodeixis includens (Walker), is an important defoliating Lepidopteran pest of southern U.S. soybean and utilizes other agronomic crops and weeds as hosts. With increasing resistance to insecticides, alternative control strategies such as induced host plant resistance were evaluated against SBL. Jasmonic acid (JA) is an elicitor of host plant resistance, and was selected to determine its fit in an IPM plan for SBL. JA was applied to the top of meridic SBL diet and fed to SBL; no effects were found. JA applied as an exogenous elicitor to cotton, sweet potato, okra, cowpea, and soybean did result …


Quantifying Tarnished Plant Bug, Lygus Lineolaris (Palisot De Beauvois), Resistance To Acephate In Louisiana, Josh T. Copes Jan 2010

Quantifying Tarnished Plant Bug, Lygus Lineolaris (Palisot De Beauvois), Resistance To Acephate In Louisiana, Josh T. Copes

LSU Master's Theses

The tarnished plant bug, Lygus lineolaris (Palisot de Beauvois), is one of the most yield- limiting insect pests attacking cotton in the Mid-Southern region of the U.S. This pest is almost exclusively managed with chemical control strategies. The organophosphate insecticide, acephate, has been one of the most important insecticides recommended to control tarnished plant bugs. In recent years, reports of unsatisfactory acephate performance have become common and actual field rates have been increased to improve control. The objective of this study was to survey acephate susceptibility in Louisiana populations of tarnished plant bug using laboratory bioassays and evaluate acephate efficacy …
