The three keys to whitefly management are sampling, effective chemical use, and avoidance. This study examines factors relevant to the latter two keys in the context of Arizona’s cotton pest spectrum. Insect growth regulators (IGRs) are central to Arizona’s success in whitefly management. The basic usage guidelines developed for the IGRs—initial treatment timing, prescribed intervals between su...
Bacillus cereus is a food contaminant with greatly varying enteropathogenic potential. Almost all known strains harbor the genes for at least one of the three enterotoxins Nhe, Hbl, and CytK. While some strains show no cytotoxicity, others have caused outbreaks, in rare cases even with lethal outcome. The reason for these differences in cytotoxicity is unknown. To gain insight into the origin o...
Viral small RNAs (vsRNAs) are one of the key elements involved in RNA silencing-based defense against viruses in plants. We analyzed the vsRNA profiles in Nicotiana benthamiana and Solanum lycopersicum infected by polygonum ringspot virus (PolRSV) (Tospovirus, Bunyaviridae). VsRNAs were abundant in both hosts, but a different size profile was observed, with an abundance peak at 21 in N. bentham...
