REPORT on an ORANGE DISEASE in CYPRUS, CAUSED BY A SCALE 
Гузест. : 
The material which forms the text of the following report was kindly 
sent me by Captain Arthur Young, Commissioner at Famagusta, who 
has also been good enough to forward me the details T the spread of 
the pest throughout Cyprus, which will be found belo 
The disease is caused by the presence of a эы insect Aspidiotus 
aurantit, Maskell, which is a member of the sub. family spine 
This sub-family with some others, compose the family Coccide, 
insecta popularly known - le insects, Bark lice, Mealy bugs, &c. 
Aspidiotus aurantii seems to have been first named Aspidiotus 
coccineus by the Greek енории Gennadius, and, since this name 
has priority, it ought to have been retained. Nevertheless, the түт 
entomologists, to whom we are almost entirely indebted for our know- 
ledge of the methods of dealing with this pest, consistently use “Maskell 8 
name, and I have therefore thought it well to do the same. ‘The species 
has also been called Aspidiotus сїйїї, and is popularly known in America 
as the Red scale of California. 
The precise home of this insect has not yet been determined, and it is 
variously stated to be Europe and Australia. It is one of the most, if 
not the most, destructive of the insects which attack orange or lemon 
trees, and is notorious for the damage it has done in California, and, 
more recently in Florida, in Australia, New Zealand, and other pacis of 
the world. A single instance of the loss this pest occasions pu 
quoted from Mr. Comstock's report of 1881. The rental of an orenge 
grove of 33 acres had to be reduced from 1,800/. © 1201. їп six чым 
on account of the ravages of this Шын 
е disease seems to have been noticed in Cyprus for the = six or 
eight years. In the district of Limassol the insect was foun 
ago in every rg at Episcopi and Kolossi, two orange Mario 8, an 
it must have been there for some years previously. At Nikosia it has 
been ы А for eight years or more, and at Larnaca for at least six 
years. It was first noticed at Famagusta in 1888, but it was only in 
1890 that the gardens were seriously affected. The sweet lemons are 
the first attacked, then the lemons, and lastly the oranges ; old and young 
_ trees are attacked alike. On the whole it seems the disease 
firm hold in the island, and Дрен measures should be at Qus 
taken to arrest its progress before it is too late.
