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/...
متن کاملSuppression of hop looper (Lepidoptera: Noctuidae) by the fungicide pyraclostrobin.
The hop looper, Hypena humuli Harris, is a reemergent pest of hop that often requires treatment to mitigate crop damage. In 4 yr of field trials, plots treated with fungicides were observed to sustain less hop looper defoliation compared with nontreated plots. Further investigation revealed that abundance of hop looper and associated defoliation were reduced when the fungicide pyraclostrobin wa...
متن کاملDomain III of Cry1Ac Is Critical to Binding and Toxicity against Soybean Looper (Chrysodeixis includens) but Not to Velvetbean Caterpillar (Anticarsia gemmatalis)
Insecticidal proteins Cry1Ac and Cry2Ac7 from the bacterium Bacillus thuringiensis (Bt) belong to the three-domain family of Bt toxins. Commercial transgenic soybean hybrids produce Cry1Ac to control the larvae of the soybean looper (Chrysodeixis includens) and the velvet bean caterpillar (Anticarsia gemmatalis). The specificity of Cry1Ac is determined by loops extending from domain II and regi...
متن کاملPLANT 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...
متن کاملDevelopment of Heterodera glycines on Soybean Damaged by Soybean Looper and Stem Canker.
Short-term greenhouse studies with soybean (Glycine max cv. Bragg) were used to examine interactions between the soybean cyst nematode (Heterodera glycines) and two other common pests of soybean, the stem canker fungus (Diaporthe phaseolorum var. caulivora) and the soybean looper (Pseudoplusia includens), a lepidopterous defoliator. Numbers of cyst nematode juveniles in roots and numbers of cys...
