| Abstract: | Parasporal crystals are insecticidal δ-endotoxin proteins(named Cry and Cyt toxins) produced by Bacillus thuringiensis(Bt) during the sporulation phase.As one of the bio-pesticides,parasporal crystals/Bt have been widely used in agriculture and forestry with the advantages of high efficiency,broad-spectrum,environmental protection and bio-safety.The latest classification and nomenclature of parasporal crystals were introduced,the research progress in their structure,insecticidal mechanism and application were reviewed in this paper,and their development prospect in Bt biological pesticides was forecasted. |
