Histopathological effects of Bacillus thuringiensis on the midgut of tobacco hornworm larvae (Manduca sexta): Low doses compared with fasting

TLDR
The present observations reveal that the columnar cells of the midgut responded cytologically in the same way to fasting as they did to exposure to the toxic spores of B. thuringiensis.

Insect Midgut Function

TL;DR: The chapter considers the cockroach as an example of a classic generalist and looks at scavenging dipteran larvae, mainly aquatic.

Specificity of Bacillus thuringiensis delta-endotoxins. Importance of specific receptors on the brush border membrane of the mid-gut of target insects.

TL;DR: In this article, the molecular basis of differences in the insecticidal spectrum of Bacillus thuringiensis delta-endotoxins was studied. But the binding sites were not significantly different on brush border membrane vesicles of Manduca sexta and H. virescens.

Importance of specific receptors on the brush border membrane of the mid-gut of target insects

TL;DR: Binding studies with three delta-endotoxins on membrane preparations from larval insect mid-gut provide new evidence that binding to a specific receptor on the membrane of gut epithelial cells is an important determinant with respect to differences in insecticidal spectrum of B. thuringiensis insecticidal crystal proteins.

Immunocytochemical localization of Bacillus thuringiensis insecticidal crystal proteins in intoxicated insects

TL;DR: The damage of different insecticidal crystal proteins (ICPs) from Bacillus thuringiensis to the midgut of Manduca sexta, Plutella xylostella, and Leptinotarsa decemlineata larvae was determined by light microscopic observations.

Cytolytic Toxin Cyt1A and Its Mechanism of Membrane Damage: Data and Hypotheses

TL;DR: The δ-endotoxins are a superfamily of proteins that occur as crystalline inclusions in the spore-forming bacterium Bacillus thuringiensis that are of considerable interest as environmentally safe insecticides.

The morphology and fine structure of the larval midgut of a moth (Manduca sexta) in relation to active ion transport.

TL;DR: Light and electron microscopic examination of the midgut of Manduca sexta has shown that the organization of this tissue is more complex than was originally believed.
