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

open access: yesInsect 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.

Iflaviruses in arthropods: when small is mighty

open access: yesInsect Science, EarlyView.
Many arthropod species harbor iflaviruses, which often cause covert (asymptomatic) infections, but may still affect host fitness. We review the impact of iflaviruses on arthropod fitness, immunity, behaviour as well as the iflavirus’ host range, transmission, tissue tropism and the interactions with other microorganisms within arthropods.

Insect Feeding Assays with Spodoptera exigua on Arabidopsis thaliana

open access: yesBio-Protocol, 2020
Plant-insect interaction is an important field for studying plant immunity. The beet armyworm, Spodoptera exigua, is one of the best-known agricultural pest insects and is usually used to study plant interactions with chewing insects. Here, we describe a

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

open access: yesInsect 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.

The chemical ecology of armyworms [PDF]

open access: yes, 2013
Moths of the genus Spodoptera are economically important pest insects. The necessity to develop novel control strategies which may be included in integrated pest management schemes has led to the study of chemical communication in several species within ...

Herbivore induction of the glucosinolate-myrosinase defense system: major trends, biochemical bases and ecological significance [PDF]

open access: yes, 2009
Like many other plant defense compounds, glucosinolates are present constitutively in plant tissues, but are also induced to higher levels by herbivore attack.
