Anticarsia gemmatalis nucleopolyhedrovirus from soybean crops in Tamaulipas, Mexico: diversity and insecticidal characteristics of individual variants and their co-occluded mixtures
In 1999, Anticarsia gemmatalis nucleopolyhedrovirus (AgMNPV) was introduced into a major soybean-growing region in Tamaulipas, Mexico, for control of its lepidopteran host, Anticarsia gemmatalis Hilbner (Lepidoptera: ... -
Generation of variability in Chrysodeixis includens nucleopolyhedrovirus (ChinNPV): the role of a single variant
The mechanisms generating variability in viruses are diverse. Variability allows baculoviruses to evolve with their host and with changes in their environment. We examined the role of one genetic variant of Chrysodeixis ... -
Genetic diversity in Chrysodeixis includens nucleopolyhedrovirus and factors involved in its generation
En la presente tesis se ha examinado la variabilidad genética de varios aislados de campo del nucleopoliedrovirus de Chrysodeixis includens (ChinNPV). Los resultados obtenidos revelan la gran ... -
Genetic variability of Chrysodeixis includens nucleopolyhedrovirus (ChinNPV) and the insecticidal characteristics of selected genotypic variants
Genetic variation in baculoviruses is recognized as a key factor, not only due to the influence of such variation on pathogen transmission and virulence traits, but also because genetic variants can form the basis for novel ... -
Genetic variation and biological activity of two closely related alphabaculoviruses during serial passage in permissive and semi-permissive heterologous hosts
Phylogenetic analyses suggest that Mamestra brassicae multiple nucleopolyhedrovirus (MbMNPV) and Helicoverpa armigera multiple nucleopolyhedrovirus (HearMNPV) may be strains of the same virus species. Most of the studies ... -
Host-virus and virus-virus interactions in broad host range alphabaculoviruses: implications for the development of virus-based insecticides
(2021) Tesis doctoral / Doktoretza tesiaEsta tesis se ha centrado en el estudio del potencial insecticida del nucleopoliedrovirus múltiple de Mamestra brassicae (MbMNPV), un virus de amplio espectro, y su interacción con el nucleopoliedrovirus múltiple de ... -
Insecticidal traits of variants in a genotypically diverse natural isolate of anticarsia gemmatalis multiple nucleopolyhedrovirus (AgMNPV)
Outbreaks of Anticarsia gemmatalis (Hübner, 1818) (Lepidoptera: Erebidae), a major pest of soybean, can be controlled below economic thresholds with methods that do not involve the application of synthetic insecticides. ... -
Regulation of multiple infection in alphabaculoviruses: critical factors that determine success
This thesis is focused in the ability of different baculovirus species to coinfect a particular host. I investigate whether the co-occlusion of different species is allowed and if it confers some advantage to the viruses, ... -
The role of Chrysoperla carnea (Steph.) (neuroptera: Chrysopidae) as a potential dispersive agent of noctuid baculoviruses
Baculoviruses (BV) are highly effective against lepidopteran pests of economic importance such as Spodoptera exigua. The combined use of entomopathogens and macrobiological control agents requires the study of their ... -
The sf32 unique gene of spodoptera frugiperda multiple nucleopolyhedrovirus (SfMNPV) is a non-essential gene that could be involved in nucleocapsid organization in occlusion-derived virions
A recombinant virus lacking the sf32 gene (Sf32null), unique to the Spodoptera frugiperda multiple nucleopolyhedrovirus (SfMNPV), was generated by homologous recombination from a bacmid comprising the complete viral genome ... -
Superinfection exclusion in alphabaculovirus infections is concomitant with actin reorganization
Superinfection exclusion is the ability of an established virus to interfere with a second virus infection. This effect was studied in vitro during lepidopteran-specific nucleopolyhedrovirus (genus Alphabaculovirus, family ...
