Spodoptera ornithogalli (Guenée) (Lepidoptera: Noctuidae) is an important pest in different crops of economic relevance in America. For its control, strategies that include chemicals are usually used; so, the description ...
Beneficial rhizobacteria inoculation on Ocimum basilicum reduces the growth performance and nutritional value of Spodoptera frugiperda
(John Wiley & Sons Ltd, 2022-02)
Plant growth-promoting rhizobacteria (PGPR) has a significant role in plant–insect interaction. However, the extent of their impact on insects is still not well understood. This investigation was designed to evaluate the ...
Bis- and mono-substituted Chalcones exert anti-feedant and toxic effects on fall armyworm Spodoptera frugiperda
(Elsevier, 2021-10)
Spodoptera frugiperda is a highly polyphagous migratory lepidopteran pest species. It causes infestation in crops leading to the severe crop losses. Being a new invasive parasite, its susceptibility to insecticides needs ...
Annonaceous Acetogenins with insecticidal effects on Spodoptera frugiperda Smith (Lepidoptera: Noctuidae)
(SCIRP, 2018-07)
Background: Annonaceous acetogenins enclose a large number of biological activities, among which the insecticidal stands out. Methods: We report herein the biocide effects of natural acetogenins from Annona squamosa, A. ...
Structural factors of annonaceous acetogenins and their semisynthetic analogues related with the toxicity on Spodoptera frugiperda
(Scientific Research an Academic Publisher, 2015-06)
Toxic and nutritional effects of annonaceous acetogenins and their semisynthetic analogues on Spodoptera frugiperda were evaluated. Structural modification of the natural ACG, blocking the OH flanking THF with MOM, allowed ...

(Entomological Society of America, 2011-08)
The long-term effects of methoxyfenozide on the longevity and reproductive processes of beet armyworm, Spodoptera exigua (Hübner) (Lepidoptera: Noctuidae), adults were assessed after exposure by ingestion. Methoxyfenozide ...
Fitness and Mating Compatibility of Spodoptera frugiperda (Lepidoptera: Noctuidae) Populations from Different Host Plant Species and Regions in Argentina
(Entomological Society of America, 2008-12)
Two strains (corn and rice) of fall armyworm, Spodoptera frugiperda (J.E. Smith) (Lepidoptera: Noctuidae), have been identified that differ in their host plant preferences and performance. Although these strains have been ...
Lethal and sublethal effects of chlorantraniliprole on Spodoptera cosmioides (Lepidoptera: Noctuidae)
(John Wiley & Sons Ltd, 2018-12)
BACKGROUND: Spodoptera cosmioides (Walker, 1858) population has increased in Bt soybean crops in Argentina. As there are no registered products for its control, the recommended insecticides for S. frugiperda are used. The ...
