Chrysodeixis includens (Lepidoptera: Noctuidae) on soybean treated with resistance inducers

Molecular Variability and Genetic Structure of Chrysodeixis includens (Lepidoptera: Noctuidae), an Important Soybean Defoliator in Brazil

This study provides the first genetic characterization of the soybean looper, Chrysodeixis includens (Walker, 1857), an important defoliating pest species of soybean crops in Brazil. Population genetic variability and the genetic structure of C. includens populations were evaluated by using ISSR markers with samples from the major soybean producing regions in Brazil in the growing seasons 2011/...

Influence of Soybean Planting Date and Leaf Age on Resistance to Corn Earworm (Lepidoptera: Noctuidae)

Environ.Entomol.21(2):264-268(1992) ABSTRACT Soybean, Glycine max (L.) Merr., resistance to insects has been shown to vary with planting date and leaf age. This study determined effects soybean genotype, planting date, and leaf age had on feeding behavior of com earworm, Helicoverpa zea (Boddie). Soybean genotypes 'Cobb' (susceptible) and 'GatIR81-296' (resistant) were planted early (29May) and...

Evaluation of seven viral isolates as potential biocontrol agents against Pseudoplusia includens (Lepidoptera: Noctuidae) caterpillars.

The caterpillar Pseudoplusia includens (Walker, 1857) (Lepidoptera, Noctuidae), known as soybean looper, is a pest that has recently assumed greater importance in soybean in Brazil. Isolates of nucleopolyhedroviruses (NPVs) of this pest have been identified from cotton in Guatemala and soybean farms in Brazil, providing an interesting perspective of potential use of viral insecticide against th...

Growth of Wild Pseudoplusia Includens (lepidoptera: Noctuidae) Larvae Collected from Bt and Non-bt Cotton

PLANT RESISTANCE Seed Yield of Near-Isogenic Soybean Lines with Introgressed Quantitative Trait Loci Conditioning Resistance to Corn Earworm (Lepidoptera: Noctuidae) and Soybean Looper (Lepidoptera: Noctuidae) from PI 229358

The development of superior soybean, Glycine max (L.) Merr., cultivars exhibiting resistance to insects has beenhindereddue to linkagedrag, a commonphenomenonwhen introgressing alleles from exotic germplasm. Simple-sequence repeat (SSR) markers were used previously to map soybean insect resistance(SIR)quantitative trait loci (QTLs) ina ÔCobbÕ PI229358population, and subsequently used tocreatene...
