Popcorn genotypes resistance to fall armyworm [PDF]

Ciência Rural, 2018
ABSTRACT: The aim of this study was to evaluate popcorn genotypes for resistance to the fall armyworm, Spodoptera frugiperda. The experiment used a completely randomized design with 30 replicates. The popcorn genotypes Aelton, Arzm 05 083, Beija-Flor, Colombiana, Composto Chico, Composto Gaúcha, Márcia, Mateus, Ufvm Barão Viçosa, Vanin, and Viviane ...

Peptidic product derived from trypsin autolysis modulates insect digestive proteases and supports plant biochemical defense

Pest Management Science, EarlyView.
XXXX Abstract BACKGROUND Spodoptera frugiperda, commonly known as the fall armyworm, is a highly economically significant pest that affects various crops, resulting in substantial losses in productivity. Managing this pest primarily relies on chemical insecticides; however, the repeated development of resistance to these chemicals has rendered them ...

High migratory potential of fall armyworm in West Africa despite stable temperatures and widely available year‐round habitats

Insect Science, EarlyView.
Despite the minimal annual temperature variation and the widespread distribution of potential year‐round habitats in Ghana, the migratory potential of the local fall armyworm remains strong and is indistinguishable from that of the fall armyworm in China, which undergo seasonal migration.
