Comparative demographic parameters of beet armyworm, Spodoptera exigua (Lep.: Noctuidae) on four commercial sugar beet cultivars
The effects of four sugar beet cultivars (Anaconda, Rozier, Evelina and Flores) on the life table parameters of beet armyworm, Spodoptera exigua (Lep.: Noctuidae) were evaluated at 26 ± 1 °C, 60 ± 5% relative humidity and a photoperiod of 16: 8 h (L: D). The highest gross and net fecundity rates were obtained on Anaconda (2573.31 ± 27.78 and 1576.31 ± 16.65 eggs/female, respectively). The net r...
متن کاملModeling seasonal migration of fall armyworm moths.
Fall armyworm, Spodoptera frugiperda (J.E. Smith), is a highly mobile insect pest of a wide range of host crops. However, this pest of tropical origin cannot survive extended periods of freezing temperature but must migrate northward each spring if it is to re-infest cropping areas in temperate regions. The northward limit of the winter-breeding region for North America extends to southern regi...
متن کاملEffects of limonoids from Cipadessa fruticosa on fall armyworm.
Six mexicanolide limonoids isolated from the dichloromethane extract of the fruits of Cipadessa fruticosa Blume (Meliaceae) were evaluated against Spodoptera frugiperda (J. E. Smith). Gedunin was used as a positive control. When incorporated into an artificial diet of neonates at 50.0 mg kg(-1), febrifugin A showed 73.3% mortality. All the compounds showed moderate insecticidal activity, except...
متن کاملThe Gypsy Moth (Lepidoptera: Lymantriidae) Nucleopolyhedrovirus as a Synergist for Baculoviruses Against Beet Armyworm, Fall Armyworm and Corn Earworm (Lepidoptera: Noctuidae)
The gypsy moth, Lymantria dispar (L.) (Lepidoptera: Lymantriidae) nucleopolyhedrovirus LdMNPV was tested as a synergist for nucleopolyhedroviruses against Helicoverpa zea (Boddie), Spodoptera exigua (Hübner), and Spodoptera frugiperda (J.E. Smith) (Lepidoptera: Noctuidae) larvae. The addition of the gypsy moth NPV significantly decreased the LC50s of AcMNPV, AfMNPV, GmMNPV, HaMNPV, HzSNPV, PxMN...
