Insect, Fungus, and other Pests, [august, 



Specimens of the larvae of the Winter Moth and the Mottled 

 Umber Moth were received in early June from Derby, where 

 they were doing much harm (see Leaflet No. 4). 



Beetles. — Specimens of the Pigmy Mangold Beetle (Ato- 

 maria linearis) were received from Chichester, and seedling 

 mangolds from Woking had every appearance of having been 

 destroyed by the same pest. This beetle is very small and 

 therefore easily overlooked, so that every year the loss of 

 seedling mangolds which are really destroyed by this pest is 

 attributed to some other cause. 



Specimens of a beetle sent from Stroud, which was 

 stated to be attacking apples, pears, raspberries, currants, 

 strawberries, peas, broad beans, runner beans, beet, roses, &c, 

 were identified as the Garden Chafer (Phyllopertha horticola), 

 a beetle dealt with in Leaflet No. 25. They should be collected 

 during the swarming period, if possible before pairing takes 

 place, and killed by dropping them into boiling water. 



Flies. — Specimens of plants from Nottingham, Mablethorpe 

 (Lines.), and Leeds, were all found to be infested with the 

 maggots of the cabbage root fly (Leaflet No. 122). In cases 

 where the attack is very severe it would be advisable to pull 

 up and burn the plants most badly infested, while the free use 

 of the hoe round the remainder would tend to the destruction 

 of the maggots and pupae. 



Parsnip leaves from Salisbury were infested by the maggots 

 of the fly Acidia heraclei, a troublesome enemy of celery and 

 parsnips, dealt with in Leaflet No. 35. 



From Salisbury also holly leaves were received and found 

 to be attacked by the Holly Leaf Miner (Chromatomyia ilicis), 

 a tiny fly, one-tenth of an inch in length, which was described 

 in this Journal in July, 1907, p. 218. 



Other Pests. — Larch from Briton Ferry (Glam.) was 

 infested with aphides, as were also gooseberry cuttings from 

 Llanelly ; a branch of nectarine from Liphook (Hants.) was 

 covered with the common Brown Scale (Lecanium persica) 

 of the peach, described at p. 195 of the Journal for June, 

 1908 ; red spiders (Leaflet No. 41) were the primary 

 cause of disease of peaches from North Walsham ; and milli- 

 pedes (Leaflet No. 94) of the species Julus pulchellus were 

 forwarded from a mangold field at Cullompton (Devon) .
