Bacillus thuringiensis Cry3Aa toxin increases the susceptibility of Crioceris quatuordecimpunctata to Beauveria bassiana infection. | The spotted asparagus beetle, Crioceris quatuordecimpunctata (Coleoptera: Chrysomelidae), is one of the most devastating pests of asparagus in China. Sprayed synthetic pesticides have been used to control C. quatuordecimpunctata damage, but they pose problems because of residues and harm to natural enemies. Neither the microbial coleopteran-specific toxin from Bacillus thuringiensistenebrionis, Cry3Aa, nor the fungal pathogen Beauveria bassiana have sufficient activity to effectively control C. ... | 2011 | 22200644 |
increased toxicity of bacillus thuringiensis cry3aa against crioceris quatuordecimpunctata, phaedon brassicae and colaphellus bowringi by a tenebrio molitor cadherin fragment. | background: biopesticides containing cry insecticidal proteins from the bacterium bacillus thuringiensis (bt) are effective against many lepidopteran pests, but there is a lack of bt-based pesticides for efficient control of important coleopteran pests. based on the reported increase in bt toxin oligomerization by a polypeptide from the cry3aa receptor cadherin in tenebrio molitor (coleoptera: tenebrionidae), it was hypothesized that this cadherin peptide, rtmcad1p, would enhance cry3aa toxicity ... | 2011 | 21495115 |
