Control Biológico de Phthorimaea operculella (Zeller, 1873) y Tecia solanivora (Povolny, 1973) (Lepidoptera: Gelechiidae) mediante Bacillus thuringiensis var. Kurstaki en papa almacenada en Cerro Punta, Chiriquí, Panamá

Adult carbohydrate feeding affects reproduction of Phthorimaea operculella (Zeller) (Lepidoptera: Gelechiidae).

Reproduction of most insects depend on nutrients accumulated during the larval stage, but many lepidopteran species will also depend on nutrients obtained at the adult stage. Feeding at the adult stage allows the intake of carbohydrate and amino acid rich solutions, which may have an effect on the species reproduction and population growth. The objectives of the current study were to characteri...

Disruption of Phthorimaea operculella (Lepidoptera: Gelechiidae) oviposition by the application of host plant volatiles

BACKGROUND Phthorimaea operculella is a key pest of potato. The authors characterised the P. operculella olfactory system, selected the most bioactive host plant volatiles and evaluated their potential application in pest management. The electrophysiological responses of olfactory receptor neurons (ORNs) housed in long sensilla trichodea of P. operculella to plant volatiles and the two main sex...

BIOLOGICAL CONTROL Insecticidal Activity of the Granulosis Virus in Combinationwith Neem Products and Talc Powder Against the Potato Tuberworm Phthorimaea operculella (Zeller) (Lepidoptera: Gelechiidae)

Las Infecciones Nosocomiales en Cuba y su Control mediante las Técnicas Moleculares de Tipificación de Microorganismos

INTRODUCCIÓN La infección nosocomial (IN), intrahospitalaria o asociada a cuidados médicos, es aquella para la que no hay evidencia de que estaba presente, o siendo incubada, al momento de la admisión del paciente. La IN suele representar la principal complicación de los pacientes admitidos a ingreso en cualquier hospital y es una causa principal de morbilidad y mortalidad a nivel global. Su oc...

Transport of Bacillus thuringiensis var. kurstaki via fomites.

The intentional and controlled release of an aerosolized bacterium provides an opportunity to investigate the implications of a biological attack. Since 2006, Los Alamos National Laboratory has worked with several urban areas, including Fairfax County, VA, to design experiments to evaluate biodefense concepts of operations using routine spraying of Bacillus thuringiensis var. kurstaki (Btk). Bt...
