Steinernema diaprepesi Nguyen & Duncan (Rhabditida: Steinernematidae), a new entomopathogenic nematode from Brazil.

Entomopathogenic nematodes (EPNs) can control pests due to their mutual association with bacteria. The use of these biological control agents is increasing worldwide due to advances in research about its control efficiency, range of action and mass production. The identification of EPNs adapted to specific environmental and climatic conditions is important for sustainable pest suppression in integrated management (IPM) programs.

(Rhabditida: Steinernematidae) parasitizing (Coleoptera: Curculionidae).

Entomopathogenic nematodes (EPNs) can control pests due to mutualistic association with bacteria that reproduce and kill the host from septicemia, making the environment favourable for nematode development and reproduction. The objective of this study was to identify an EPN isolate collected in eucalyptus cultivation and to determine its pathogenicity with regard to Marelli (Coleoptera: Curculionidae). Four steel-mesh traps with two seventh-instar larvae were buried 5 cm deep in the soil in a commercial plantation.

Cell-line-dependent crystal morphology and sublocalization of the Thyrinteina arnobia cypovirus polyhedrin expressed from a recombinant baculovirus.

We describe an unexpected feature observed for the heterologous expression of the Thyrinteina arnobia cypovirus polyhedrin from a recombinant baculovirus infection in different insect cell lines. The in cellulo-formed crystals varied in size and shape depending on the cell line. Crystals formed in Trichoplusia ni-derived cells were cubic (0.

Genomic analysis of a cypovirus isolated from the eucalyptus brown looper, Thyrinteina arnobia (Stoll, 1782) (Lepidoptera: Geometridae).

The eucalyptus brown looper, Thyrinteina arnobia (Stoll, 1782) (Lepidoptera: Geometridae), is the main lepidopteran defoliator of eucalyptus plantations in Brazil. Outbreaks of this insect pest are common in Brazil and can affect the productivity of planted forests severely. T.
