Genetic variability of Spodoptera frugiperda Smith (lepidoptera: Noctuidae) populations form Latin America is associated with variations in susceptibility to Bacillus thuringiensis cry toxins

Article Abstract:

A study characterized Bacillus thuringiensis strains isolated from Latin American soil samples that showed toxicity against three-Spodoptera frugiperda populations from different geographical areas. Results reveal that the different S. frugiperda populations display different susceptibilities to the selected B. thuringiensis strains and also to pure preparations of Cry1B, Cry1C, and Cry1D toxins.

Occurrence of natural Bacillus thuringiensis contaminants and residues of Bacillus thuringiensis-based insecticides on fresh fruits and vegetables

Article Abstract:

The occurrence of Bacillus thuringiensis on fresh fruits and vegetables for sale in Danish retail shops, including natural contaminants, as well as residues of B thuringiensis-based insecticides is examined. The results have indicated that residues of B thuringiensis-based insecticides are present on fresh fruits and vegetables and they are potentially enterotoxigenic.

Identification of cry11-type genes from Bacillus thuringiensis strains and characterization of a novel cry11-type gene

Article Abstract:

Research has been conducted on Bacillus thuringiensis cry11-type genes. The authors describe the use of PCR-restriction fragment length polymorphism method developed for identification of these genes.
