Biosynthesis and processing of Spodoptera frugiperda -mannosidase III [PDF]

Glycobiology, 2002
We previously cloned a lepidopteran insect cell cDNA that encodes a class II alpha-mannosidase that is localized in the Golgi apparatus but is cobalt-dependent, has a neutral pH optimum, hydrolyzes Man(5)GlcNAc(2) to Man(3)GlcNAc(2), and cannot hydrolyze GlcNAcMan(5)GlcNAc(2).

Identification of an Argentinean isolate of Spodoptera frugiperda granulovirus

Revista Argentina de Microbiología, 2019
The fall armyworm, Spodoptera frugiperda (J.E. Smith) (Lepidoptera: Noctuidae), is an important maize pest. Due to the environmental impact and emergence of resistance caused by chemical pesticides and transgenic events, the use of baculoviruses becomes a safe and useful alternative for its control in integrated pest management strategies.
