Streamlined phage display library protocols for identification of insect gut binding peptides highlight peptide specificity

Autor: Ruchir Mishra, Ya Guo, Pavan Kumar, Pablo Emiliano Cantón, Clebson S. Tavares, Rahul Banerjee, Suyog Kuwar, Bryony C. Bonning

Publikováno v: Current Research in Insect Science, Vol 1, Iss , Pp 100012- (2021)

Phage display libraries have been used to isolate insect gut binding peptides for use as pathogen transmission blocking agents, and to provide artificial anchors for increased toxicity of bacteria-derived pesticidal proteins. Previously, phage clones

Strong Fitness Costs of Fall Armyworm Resistance to Dual-Gene Bt Maize Are Magnified on Less-Suitable Host-Crop Cultivars

Autor: Oscar F. Santos-Amaya, Clébson S. Tavares, João Victor C. Rodrigues, Eugênio E. Oliveira, Raul Narciso C. Guedes, Eliseu José G. Pereira

Publikováno v: Agronomy, Vol 12, Iss 3, p 682 (2022)

We examined the fitness costs of resistance to transgenic Cry1A.105+Cry2Ab2 Bacillus thuringiensis (Bt) maize in the fall armyworm, Spodoptera frugiperda, a globally invasive pest species. Using Bt-resistant and -susceptible populations of similar ge

Plant Resistance in Some Modern Soybean Varieties May Favor Population Growth and Modify the Stylet Penetration of Bemisia tabaci (Hemiptera: Aleyrodidae)

Autor: Mauricélia F Almeida, Marcelo Coutinho Picanço, Clébson S. Tavares, Eugênio E. Oliveira, Eliseu José G. Pereira, Euires O Araújo

Publikováno v: Journal of Economic Entomology. 114:970-978

Complaints of severe damage by whiteflies in soybean fields containing genetically engineered (GE) varieties led us to investigate the role of transgenic soybean varieties expressing resistance to some insects (Cry1Ac Bt toxin) and to herbicide (glyp

Facing Bt toxins growing up: Developmental changes of susceptibility to Bt corn hybrids in fall armyworm populations and the implications for resistance management

Autor: Eugênio E. Oliveira, Clébson S. Tavares, Eliseu José G. Pereira, Oscar F. Santos-Amaya, Silvana V. Paula-Moraes

Publikováno v: Crop Protection. 146:105664

Developmental changes in target-pest susceptibility to Bacillus thuringiensis (Bt) toxins matter to resistance management in Bt crops, especially in certain refuge modalities. We determined the cumulative, lethal and sublethal effects of Bt corn hybr

Magnitude and Allele Frequency of Cry1F Resistance in Field Populations of the Fall Armyworm (Lepidoptera: Noctuidae) in Brazil

Autor: João Victor C. Rodrigues, Analiza P. Alves, Nilson Rodrigues-Silva, Raul Narciso C. Guedes, Thadeu Carlos de Souza, Clébson S. Tavares, Oscar F. Santos-Amaya, Eliseu José G. Pereira

Publikováno v: Journal of Economic Entomology. 110:1770-1778

Bacillus thuringiensis (Bt) corn producing the Cry1F protein was the first highly efficacious Bt corn deployed against the fall armyworm Spodoptera frugiperda (J.E. Smith) (Lepidoptera: Noctuidae) in Brazil, but reduced efficacy of this technology ag

Egg Albumin as a Protein Marker to Study Dispersal of Noctuidae in the Agroecosystem

Autor: Thomas E. Hunt, Ana María Vélez, Arnubio Valencia-Jiménez, Silvana V. Paula-Moraes, Eliseu José G. Pereira, Clébson S. Tavares

Publikováno v: Environmental Entomology.

Knowledge of dispersal and spatial dynamics of pest populations is fundamental for implementation of integrated pest management and integrated resistance management. This study evaluated 1) the effectiveness of egg white albumin protein to mark larva

Publikováno v: Pest Management Science. 73:35-43

BACKGROUND The presence of fitness costs of resistance to Bacillus thuringiensis (Bt) insecticidal proteins in insect populations may delay or even reverse the local selection of insect resistance to Bt transgenic crops, and deserves rigorous investi
