Changes in the chemistry of the haemolymph of the corn borers Chilo agamemnon (Crambidae) and Ostrinia nubilalis (Pyraustidae) after treatment with Bacillus thuringiensis
Archives of Phytopathology and Plant Protection 32 (3), 249-256
Abstract: The mode of action of Bacillus thuringiensis (B.t.) has been investigated in the two corn borers, Chilo agamemnon and Ostrinia nubilalis. Quantitative changes in the proteins and free amino acids of the haemolymph of the two insect species were detected after treatment with B.t. A marked decrease in the total proteins was observed. Most amino acids showed an obvious decrease in the haemolymph of the larvae two days after treatment with B.t. Glutamic acid, on the other hand showed a marked increase after treatment (2-3 folds). Treatment of the larvae of the two tested species caused some changes in the concentration of some ions in the haemolymph. Phosphorous and calcium ions showed some decrease as a result of treatment with B.t. but in varying degrees in the two tested species. Sodium ions showed no changes after treatment in the two species. Potassium ions also showed no changes with respect to C. agamemnon, while it decreased in O. nubilalis.
