potato. The owner of one of the potato fields, however, applied 
green arsenoid, at the rate of 1 pound to 50 gallons water, and nearly 
ruined the potato vines. 
Arsenate of lead has given the best results, with no injury to the 
foliage, while Paris green and green arsenoid give each about the 
same results, both being inferior to the arsenate of lead. 
Experiments with whale-oil soap, Owens Standard brand, 1 pcund 
to 2 gallons of water, had no effect on either larvee or adult Doryphora. 
The same brand of soap was applied against Diabrotica vittata, at a 
strength of 1 pound of soap to 1, 2, 4, and 8 gallons of water. A mix- 
ture of 1 pound to 2 gallons of water, or weaker, did not prove sue- 
cessful as a repellant, while 1 pound to each gallon of water kept the 
beetles away, but seriously injured the cucumber plants to which the 
mixture was applied. One pound of this soap to 8 gallons of water 
was ineffective against Aphis on cherry, but the same strength com- 
pletely repelled the three-lined plant-bug from chrysanthemums so 
that the plants were not again attacked by this insect. 
Tobacco dust was ineffective against Doryphora 10-lineata, Phyllo- 
treta vittata, and Diabrotica vittata. 
FRUIT SERIOUSLY INJURED BY MOTHS. 
By C. W. MALLY, Cape Town, South Africa. 
During May, 1900, numerous letters were received complaining of 
serious injury to fruit by moths, specimens of which were submitted 
to Mr. L. Peringuéy, assistant curator South African Museum, who 
determined them as Ophiuza lienardt. 
With the exeeption of one specimen, this is the only species rep- 
resented in the material received from the fruit growers. A summary 
of the correspondence has been given in the Agricultural Journal for 
July 5, 1900. 
The moths were apparently most injurious in the East London dis- 
trict, serious complaints coming from East London, Komgha, Fort 
Jackson, Kentbury, and as far inland as Grahamstown. 
It frequently occurs that a number of moths cluster on a single 
fruit, and some of the reports indicate that there was seareely a fruit 
that was not covered with moths. One correspondent reports the 
moths as swarming on a load of pineapples that were being taken to 
market. Some idea of the seriousness of the injury may be gathered 
from the statement of Mr. Walter A. Edmonds, Komgha, that ‘‘ 20,000 
extra fine oranges, on all of which, except those picked half green, 
directly the moths appeared, have been spoiled.” Thus far injury to 
the following fruits has been reported: Apples, pears, plums, grapes, 
peaches, figs, oranges, guavas, bananas, pineapples, loquats, and 
medlars; also ‘‘ native fruits, berries, and flowers.” 
The fruit growers agree as to the importance of the pest; but their 
observations on the habits of the adult are considerably at variance.
