Bacillus thuringiensis (Bt) is the most extensively studied Gram-positive entomopathogenic bacterium, with numerous strains carrying plasmids containing a diverse array of pesticidal genes. This characteristic has established Bt-based products as the predominant commercially available microbial insecticides today. Among these products are insecticidal proteins, both crystalline and vegetative, which are well-known for their high toxicity against a wide range of invertebrates. Many of these prot...
Bacillus thuringiensis (Bt) is the most extensively studied Gram-positive entomopathogenic bacterium, with numerous strains carrying plasmids containing a diverse array of pesticidal genes. This characteristic has established Bt-based products as the predominant commercially available microbial insecticides today. Among these products are insecticidal proteins, both crystalline and vegetative, which are well-known for their high toxicity against a wide range of invertebrates. Many of these proteins have been incorporated into crops, offering protection against some of the most devastating insect pest species worldwide. However, insects targeted by Bt crops have been continuously exposed to selective pressures, leading to the development of resistance to some of the most commonly used insecticidal proteins. Consequently, ongoing global screening programs seeking strains with new insecticidal proteins to address resistance and expand the variety of susceptible hosts are continuously developed. This reprint aims to compile information that is relevant to this issue, encompassing descriptions of novel isolated Bt strains and invertebrate active proteins exhibiting previously uncharacterized biocidal activities, which will benefit numerous stakeholders in agribusiness, the economy, and wider society.
