PEA, 
Codlin Moth (Carprcaps1 pomonella, vid. “ Apple’). ; 
Pernicious or St. José Seale (Aspidiotus perniciosus, vid. “ Apple’). 
Leaf Slug (Hriocampa cerasi, Peck). The larva of a small 4-winged fly 
that is slug-like in appearance, and that adheres to the upper surface of the 
leaf whilst it devours the spongy tissue thereof. Also attacks both pear and 
plum in a similar manner. Very injurious at times, quite defoliating the trees. 
Already introduced to some of the other colonies.* On pear, quince, cherry, or 
plum nursery stock and in earth in which same are packed, since larve hiber- 
nate in soil. From the southern colonies including New Zealand; also from 
Europe and North America. 
Pear Midge (Diplosis pyrivora, Rilev). This insect resembles in appear- 
ance the Hessian Fly, lays its eggs in the flower-bud, and the resulting maggots 
find their way to the centre of the newly-set fruit, that becomes de‘ormed and 
is retarded in its development. In soil in which midge-infested pears have been 
growing, and used for protecting roots of nursery stock. From United States 
of America. Introduction not very probable. 
Pear-tree Psylla (Psylla pyricola). “A smail 4-winged ~ sucking 
insect, occurring often very numerously ov foliage of tree, covering same with 
honey-dew, the presence of which results in a general black discolouration. 
Also occurs on apple. In cases or on nursery stock, especially apple or pear, 
in or on which perfect insect is hibernating. Formerly introduce from 
Europe to the United States of America; may come, therefore, from either of 
these regions, but not very likely to arrive here. 
QUINGE. 
Leaf Slug (Eriocampa cerasi, Peck, vid. “ Pear’). 
Pernicious or St. José Seale (Aspidiotus perniciosus). ; 
Quince Scale (Aspidiotus eydonie, Comstock, vid. “ Apple’’). On garden 
plants and on nursery stock, especially quince. From Sandwich Islands (A. 
Kobele), and from United States of America. 
INSECTS INJURING STONE-FRUIT TREES. 
Peacn, 
Pernicious or St. José Scale (Aspidiotus perniciosus, vid. “ Apple’). 
Indian Peach Maggot (Rivellia persice, Bigot). Pest of similar habit to 
the common fruit maggot of Queensland and New South Wales. In fruit 
from India. (H. C. Cotes.) 
East Indian Fruit Maggot (Ceoratitis capitata, Wied.). Pest of. similar 
habit to the common fruit maggot of Queensland and New South Wales. In’ 
fruit. From East Indics, Western Australia, Cape of Good Hope, &e. nha 
Japanese Peach Fruit-worm (Carpocapsa, sp.). Regarding this pest and its 
depredations in Japan, it has been stated as follows :—* Peach crop rendered 
almost a complete failure, so-far at least as the quality ct the fruit is 
concerned, by the attacks of a small lepidopterous larva which bores the fruit, 
causes it to decay, prevents it coming to a sound maturity and ripening in a 
marketable condition.” Insect Life, vol. i., p- 58. 1888.+ In the soil of 
orchards wherein peaches are grown, used in packing nursery stock. From 
Japan. : 
* The following testimonies are significant :—‘*I am sorry to say that the cherry-leach is 
spreading with great rapidity. It is only six years since it first made its appearance from New 
fren but it is now all over Southern Tasmania.”—E. H. Thompson, [nscet Life, vi., p. 87, 
ip. 1893. ‘
