Abstract
|
|
|
|
Surface changes of tissues caused by B. thuringiensis var. kurstaki б-endotoxin intoxication of Helicoverpa assulta were observed by scanning electron microscopy.Bt-endotoxin crystals induced the erosion and disruption on the surface of all tissues tested. The results revealed that the toxin binds to all exposed plasma membranes without apparent specificity for particular membrane domains.
