Sublethal infections by Spodoptera exigua multiple nucleopolyhedrovirus (SeMNPV) are common in field populations of the beet armyworm (S. exigua, Hübner) in the Almerian horticultural region of Spain. Inoculation of second, third, and fourth instars with occlusion bodies (OBs) of an isolate (VT-SeAl1) associated with vertically transmitted infections resulted in 15 to 100% of sublethal infectio...

The toxicity of malathion to Solea senegalensis was studied in a static renewal bioassay during its first month larval life (between 4 and 30 dph). Through the use different biomarkers biochemical, cellular molecular approaches (inhibition cholinesterases [ChEs], changes cytochrome P450-1A [CYP1A] study histopathological alterations), effects three concentrations (1.56, 3.12, 6.25 μg/L) have be...

Two greenhouse studies were conducted to investigate the variability in tolerance to a sublethal dose of glyphosate among accessions of pitted morningglory, hybrid morningglory (a fertile hybrid between pitted and sharppod morningglory), and sharppod morningglory, collected from several states in the southern United States. The first study was conducted to evaluate the variability in tolerance ...
