A DNA-based approach to infer species diversity of larvae and adults from the white grub genus (Coleoptera: Scarabeidae).

Scarabaeoidea is a diverse and widely distributed insect group; many are agricultural pests including species within the genus . Species diversity studies in this taxonomic group are done mainly using morphological identification. However, despite existing taxonomic keys for adults and larvae, identification may be difficult due to their complex morphology.

Baseline of Susceptibility to the Cry1F Protein in Mexican Populations of Fall Armyworm.

The fall armyworm, Spodoptera frugiperda (J. E. Smith) (Lepidoptera: Noctuidae), is currently the most important maize pest in Mexico.

Interaction of Beauveria bassiana and Metarhizium anisopliae with chlorpyrifos ethyl and spinosad in Spodoptera frugiperda larvae.

Background: The high natural resistance of the fall armyworm (FAW) to entomopathogenic fungi and the speed at which it develops resistance to chemical insecticides make it difficult to control in several crops where it is a key pest. The aim of the study was to improve mortality by combining a 50% lethal concentration of chlorpyrifos ethyl or spinosad with the entomopathogenic fungus Beauveria bassiana (Bb88) or Metarhizium anisopliae (ETL).

Results: Three main results were obtained.
