Abstract:

"The hawk moth Theretra oldenlandiae (Fabricius) is an important insect pest because in the larval stage it feeds on agricultural crops and ornamental plants such as the eddoe and garden balsam. In this study, we established methods for rearing T. oldenlandiae in the laboratory using an artificial diet containing dry powder of a wild grass Cayratia japonica (Thunb.) Gagnep. Several artificial diets were tested with different ratios of a commercial diet, Insecta LFM, and the dry leaf powder, and including different antibiotics, and the composition of the standard diet on which larvae performed best was determined. The standard diet contains 20 g of Insecta LFM, 4 g of leaf powder, 100 ml of water, 75 mg of chloramphenicol, and 200 μl of propionic acid. Larvae reared on the standard diet became larger pupae than those reared on C. japonica leaves. This result suggests that the larvae have growth potential that is masked on C. japonica leaves, and that C. japonica may not be the most suitable host species for T. oldenlandiae larvae in terms of nutrient level."
