Evaluation Of Bacillus Thuringiensis Corn Containing Pyramided Traits For Management Of Sugarcane Borer, Diatraea Saccharalis (F.), David Sindani Wangila
Evaluation Of Bacillus Thuringiensis Corn Containing Pyramided Traits For Management Of Sugarcane Borer, Diatraea Saccharalis (F.), David Sindani Wangila
LSU Master's Theses
The sugarcane borer, Diatraea saccharalis (F.), is a major target of Bacillus thuringiensis (Bt) corn in the U.S. mid southern region. Corn expressing pyramided Bt proteins has recently become commercially available in the U.S. The objectives of this study were 1) to determine survival and plant injury of Cry1Ab-susceptible (Cry1Ab-SS), -resistant (Cry1Ab-RR), and –heterozygous (Cry1Ab-RS) genotypes of D. saccharalis on Bt corn containing single and pyramided Bt genes and 2) to assess larval movement of D. saccharalis in different planting patterns of non-Bt and Bt corn. One laboratory leaf tissue bioassay and two independent greenhouse trials were conducted to evaluate …

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 …
