[ES] Se describen dos nuevos genotipos del nucleopoliedrovirus simple de Helicoverpa armigera, HearSNPV, HearSNPV-SP1B y HearSNPV-LB6, cada uno procedente de mezclas de genotipos obtenidas de localizaciones y cultivos diferentes. Cada uno de ellos tiene una actividad insecticida específica frente a larvas de H. armigera comparable a la de los insecticidas comerciales habituales. Además, la mezcla de los dos genotipos, particularmente en proporción 1:1 con viriones co-ocluidos de genotipos mezclados, es capaz de controlar las plagas de H. armigera en cultivo de tomate, siendo tan eficaz como los insecticidas utilizados habitualmente, químicos o biológicos. Su uso como bioinsecticida representa una tecnología segura para los vertebrados, por ser específico de artrópodos. Además puede producirse con facilidad y buen rendimiento por inoculación oral de larvas de H. armigera con cuerpos de oclusión de HearSNPV.
[EN] The invention relates to two novel genotypes of the Helicoverpa armigera single nucleopolyhedrovirus HearSNPV, HearSNPV-SP1 B and HearSNPV-LB6, each one originating from mixtures of genotypes obtained from different locations and cultures. Each one has a specific insecticide activity for controlling Helicoverpa armigera larvae comparable to that of the usual commercial insectides. Furthermore, the mixture of the two genotypes, especially in a ratio of 1:1, with co-occluded virions of mixed genotypes, can control H. armigera pests in tomato cultures just as effectively as chemical or biological insecticides that are used normally. The use thereof as a bioinsecticide represents a safe technology for vertebrates, specifically arthropods. It can also be produced easily, with a high yield, as a result of the oral inoculation of H. armigera larvae with HearSNPV occlusion bodies.
