Two genomes of highly polyphagous lepidopteran pests (Spodoptera frugiperda, Noctuidae) with different host-plant ranges
Emergence of polyphagous herbivorous insects entails significant adaptation to recognize, detoxify and digest a variety of host-plants. Despite of its biological and practical importance - sinceExpand

Pheromonal Divergence Between Two Strains of Spodoptera frugiperda
Spodoptera frugiperda consists of two genetically and behaviorally different strains, the corn- and the rice-strain, which seem to be in the process of sympatric speciation. We investigated the roleExpand

Genetic basis of allochronic differentiation in the fall armyworm
BackgroundVery little is known on how changes in circadian rhythms evolve. The noctuid moth Spodoptera frugiperda (Lepidoptera: Noctuidae) consists of two strains that exhibit allochronicExpand

Population structure of Spodoptera frugiperda maize and rice host forms in South America: are they host strains?
Determining which factors contribute to the formation and maintenance of genetic divergence to evaluate their relative importance as a cause of biological differentiation is among the majorExpand

Geographic Variation in Sexual Attraction of Spodoptera frugiperda Corn- and Rice-Strain Males to Pheromone Lures
The corn- and rice-strains of Spodoptera frugiperda exhibit several genetic and behavioral differences and appear to be undergoing ecological speciation in sympatry. Previous studies reportedExpand

Chasing sympatric speciation: The relative importance and genetic basis of prezygotic isolation barriers in diverging populations of Spodoptera frugiperda
This thesis investigates the mechanisms underlying three prezygotic isolation barriers between the corn- and the rice-strain of the noctuid moth Spodoptera frugiperda to determine possibleExpand

Adaptation by copy number variation increases insecticide resistance in fall armyworms
Insecticide resistance is a major main challenge in pest control, and understanding its genetic basis is a key topic in agricultural ecology. Detoxification genes are well-known genetic elements thatExpand

Host plant specialization in the generalist moth Heliothis virescens and the role of egg imprinting
Even though generalist insects are able to feed on many different host plants, local specialization may occur, which could lead to genetic differentiation. In this paper we assessed the level andExpand

Sexual communication of Spodoptera frugiperda from West Africa: Adaptation of an invasive species and implications for pest management
The pest species Spodoptera frugiperda, which is native to North and South America, has invaded Africa in 2016. The species consists of two strains, the corn-strain and rice-strain, which differ inExpand
