Grapevine defoliation by Spodoptera frugiperda Smith, 1797 (Lepidoptera: Noctuidae) in Brazil

Ciência Rural, 2021
: The fall armyworm, Spodoptera frugiperda Smith, 1797 (Lepidoptera: Noctuidae), is a polyphagous pest that causes losses in several crops. The knowledge of host plants is essential for establishing management and control strategies.

The Effect of Temperature on the Development of Spodoptera frugiperda (Lepidoptera: Noctuidae)

Insects, 2020
The fall armyworm (Spodoptera frugiperda) is a pest of tropical origin which recently invaded Africa, the Far East and Australia. Temperature, therefore, plays an important role in its invasion biology, since this pest does not go into diapause.

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.

Selection, counterselection, and conditional gene expression for genetic biocontrol of insects

Insect Science, EarlyView.
Selection, counterselection, and conditional expression can be used for sex separation. Selection (S) and counterselection (CS) genes are linked to the sex chromosomes (e.g., the X and Y chromosomes) to confer sex‐specific selection or counterselection based on the presence or absence of the S or CS genes.

A systematic review on research trends and commercialised entomopathogenic nematodes: A global perspective

Agricultural and Forest Entomology, EarlyView.
Out of 136 identified EPNs, only 18 (8 Steinernema and 6 Heterorhabditis) are commercialised globally, highlighting a major gap between discovery and application. High production costs and inconsistent field efficacy are the leading obstacles to the widespread commercialisation of EPN‐based biocontrol products.
