    This historic book may have numerous typos and missing text. Purchasers can download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1912 Excerpt: ... fruit-flies--genus Dacus--in India. After this oil was spread over the leaves the flies became so thick around it that a thousand were captured with a few sweeps of the net. When the flies were very abundant in the trees during July, the writer covered several of the leaves and apples in the Bough and Primate trees with citronella oil and placed a shallow dish of it in the branches. Careful observations were made during the next two days and not a single fly was observed to come near the oil. It apparently acted as a deterrent, as it is said to do in the case of mosquitoes. The oil burned the fruit, causing the coat to turn brown and apparently die. The use of kerosene for the Mediterranean fruit-fly in Australia has been strongly recommended by Compere (1907) and by Gurney (1908), numerous flies being caught in saucers exposed in the trees. The firstnamed author describes also a self-feeding kerosene trap that has proved very effective. In the experiments here described, kerosene was placed in saucers in the trees where citronella oil had been tried and some was also applied on the fruit where the flies were ovipositing. The only result noted was that the flies appeared to avoid the kerosene as they had avoided the citronella oil. Quassia is a recognized fly-poison, altnough used commonly by man as a medicine. A sweetened decoction was made by soaking quassia chips, and this was sprayed on the fruit and foliage in the cage experiments. The flies ate the sweetened, bitter liquid freely but no harm came to them. Similar negative results are recorded by Lounsbury (1899) from his use of quassia with fruit-flies in South Africa. Cold-storage Several published records indicate that the larvae of fruit-flies and some other pests are destroyed by continual low te.
