Cry1F Resistance in Fall Armyworm Spodoptera frugiperda: Single Gene versus Pyramided Bt Maize

Evolution of insect resistance to transgenic crops containing Bacillus thuringiensis (Bt) genes is a serious threat to the sustainability of this technology. However, field resistance related to the reduced efficacy of Bt maize has not been documented in any lepidopteran pest in the mainland U.S. after 18 years of intensive Bt maize planting. Here we report compelling evidence of field resistan...

Effects 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...

Modeling 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...

Plant Pest Risk Assessment for Pioneer 4114 Maize

Pioneer Hi-Bred International, Inc. (referred to as “Pioneer” hereafter) has petitioned APHIS (USDA-APHIS Petition Number #11-244-01p, referred to as “Petition”) for a determination that genetically engineered (GE) corn (Zea mays) event DP-ØØ4114-3 (referred to as “4114 maize” or “4114”) is unlikely to pose a plant pest risk and, therefore, is no longer a regulated article under regulations at ...
