Toxicity and application of neem in fall armyworm

Comunicata Scientiae, 2015
Aqueous extracts of neem, Azadirachta indica A. Juss., leaf and seed cake were tested for toxicity in Spodoptera frugiperda (J. E. Smith, 1797) (Lepidoptera: Noctuidae) utilizing different methods of application (foliar and systemic). Probit analysis was used to determine the LC50 and regression analysis for mortality at different concentrations of the

Two host‐plant strains in the fall armyworm

Insect Science
AbstractThe fall armyworm (Spodoptera frugiperda) is one of the major pest insects damaging diverse crops including cotton, corn, rice, and sorghum. Fall armyworms have been identified as two morphologically indistinguishable strains, the corn strain, and the rice strain, named after their preferred host‐plants.

Resistance to Fall Armyworm in Converted Sorghums

The Florida Entomologist, 1990
Field experiments were conducted in 1988 to evaluate newly converted sorghum, Sorghum bicolor (L.) Moench, germplasm for both whorl and panicle resistance to feeding by larvae of the fall armyworm (FAW), Spodoptera frugiperda (J. E. Smith). In the whorl-stage resistance study, over 20 and 30 of the entries were significantly more resistant to FAW ...
