GENETIC CHARACTERIZATION OF FALL ARMYWORM (SPODOPTERA FRUGIPERDA) IN ECUADOR AND COMPARISONS WITH REGIONAL POPULATIONS IDENTIFY LIKELY MIGRATORY RELATIONSHIPS.

Fall armyworm, Spodoptera frugiperda (J.E.Smith), is an important agricultural pest native to the Americas that has recently been introduced into the Eastern Hemisphere where it has spread rapidly through most of Africa and much of Asia.The long-term economic consequences of this invasion will depend on how the species and important subpopulations

The oxidation of biogenic volatile organic compounds (BVOCs) gives a range of products, from semi-volatile to extremely low-volatility compounds.To treat the interaction of these secondary organic vapours with the particle phase, global aerosol microphysics models generally use either a thermodynamic partitioning approach (assuming instant equilibr

Abstract Background Interspecies animal hybrids can employ clonal or hemiclonal reproduction modes Eared Roaster where one or all parental genomes are transmitted to the progeny without recombination.Nevertheless, some interspecies hybrids retain strong connection with the parental species needed for successful reproduction.Appearance of polyploid
