Fall Armyworm: Control with Insecticides

open access: yesThe Florida Entomologist, 1979
Control measures for fall armyworm, (FAW), Spodoptera frugiperda (J. E. Smith), vary with the crop and its stage of development. Generally, seedling plants sustain economic damage with fewer larvae/unit area than do more mature plants. Resistance to insecticides for control of the FAW has been demonstrated for carbaryl and trichlorfon, but not for ...

Prospecting of popcorn hybrids for resistance to fall armyworm

open access: yesGenetics and Molecular Research, 2014
The fall armyworm, Spodoptera frugiperda, is the pest that causes the greatest economic losses for both common corn and popcorn crops, and the use of resistant plant genotypes is an important tool for integrated pest management. The goal of the present study was to evaluate the damage caused by S.

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.

Genetic basis of allochronic differentiation in the fall armyworm

open access: yesBMC Evolutionary Biology, 2017
Very little is known on how changes in circadian rhythms evolve. The noctuid moth Spodoptera frugiperda (Lepidoptera: Noctuidae) consists of two strains that exhibit allochronic differentiation in their mating time, which acts as a premating isolation barrier between the strains.

Drivers of Mouse Plagues: Exceptional Rainfall Following Prolonged Drought Triggers Mouse Plagues in Southeastern Australia

open access: yesIntegrative Zoology, EarlyView.
This study identified a specific sequence of an extended drought followed by exceptional rainfall as a necessary precursor for mouse plagues in southeastern Australia. Long‐term rainfall anomalies interact with ecological processes to reset population dynamics, creating conditions that support rapid mouse population growth following periods of ...

Life-history and life-table parameters of fall armyworm (Spodoptera frugiperda) for maize (Zea mays) in tropical Indian condition

open access: yesThe Indian Journal of Agricultural Sciences, 2022
Fall armyworm (Spodoptera frugiperda (J. E. Smith)) is an invasive pest reported in 2018 from India which principally attacks maize during vegetative and reproductive stages.

Popcorn genotypes resistance to fall armyworm [PDF]

open access: yesCiência 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 ...

From biology to biotechnology: Host‐regulation factors from parasitoid wasps are a source of bioactive molecules with translational potential

open access: yesInsect Molecular Biology, EarlyView.
Parasitoid wasps deploy maternal and embryonic factors to reprogramme host physiology. Venom, calyx fluid, polydnaviruses, teratocytes and larval secretions act in a coordinated, compartmentalised manner. Host‐regulation factors are promising sources of insecticidal, antimicrobial and bioinspired translational molecules.
