説明
<jats:p>The luminal membrane of larval midgut cells is the site of action of insecticidal delta‐endotoxin from <jats:italic>Bacillus thuringiensis</jats:italic>. At concentrations that correspond to normal effective doses in vivo, the toxin inhibits the uptake of amino acids by brush border membrane vesicles prepared from midguts of <jats:italic>Pieris brassicae</jats:italic> larvae. The toxin does not interact with the K<jats:sup>+</jats:sup>‐amino acid symport but rather increases the K<jats:sup>+</jats:sup> permeability of the membrane. The toxin does not increase the permeability of lepidopteran midgut brush border membrane to either Na<jats:sup>+</jats:sup> or H<jats:sup>+</jats:sup> nor does it increase the K<jats:sup>+</jats:sup> permeability of brush border membrane vesicles prepared from mammalian small intestine,</jats:p>
