Wallace (M.). Cheese Mites. —Agric. Gazette of New South Wales, 

 Sydney, xxvi, pt. 8, August 2nd 1915, pp. 699-700. 



The cheese mite, Tyroylyphus siro, multiplies quickly in cheese, 

 bacon or flour. The mites are capable of fasting for weeks or even 

 months in the hypopus stage until transferred to fresh food supplies 

 by mice, flies or other agents. They rarely attack new cheese even 

 when present in large numbers, but prefer damaged or long-stored 

 cheese. Pressed cheeses generally escape with small damage, as the 

 rind is too hard, but if the store be damp and warm, even these may 

 be badly attacked. The proper finishing of the cheese is important, as 

 loose binding or cracked rinds offer little resistance to the mite ; the 

 double-banking of matured cheese also favours the mites and 

 incidentally damages the cheeses. The absolute removal of all mites 

 from an infested cheese-room is practically impossible, but extreme 

 cleanliness of all uprights, walls, floors and shelving, the removal of 

 all broken and damaged cheeses and the systematic scrubbing of the 

 walls and woodwork with an emulsion of soft soap and kerosene, is 

 the best means of keeping them down. Fumigation with sulphur may 

 be resorted to in bad cases.

The tree-crickets of New York State include seven species of the 

 genus Oecanthus and one species of the genus Neoxabea. The time 

 of hatching of 0. niveus, 0. angustipennis, 0. fasciatus (nigricornis) 

 and 0. quadripunctatus in western New York is from 10th to 20th 

 June. Further south, hatching is earlier. The food of the members 

 of this genus consists both of plants and animals. In the breeding 

 cages, the food almost entirely consisted of Aphids, while San Jose 

 scale [Aspidiotus 2Jerniciosus] was also readily attacked. 0. fasciatus, 

 Fitch, appeared to feed more extensively on plant tissue. The eggs 

 are deposited in holes in the bark of the host tree, produced by the 

 action of the ovipositor. 0. niveus, de Geer, is distributed generally 

 over the United States, ranging from Massachusetts to the Pacific 

 Coast and from Ontario in the north to Mexico in the south. It 

 is a tree and bush-inhabiting form, found in apple orchards and 

 occasionally in raspberry plantations, shrnbberies, etc. The eggs are 

 deposited in the inner bark of the host, or in the case of raspberry 

 canes, in the fleshy area at the side of the bud in the leaf axil. 

 0. angustipennis, Fitch, is common in the lake region of the western 

 part of New York and on Long Island, and outside the State probably 

 has the same range as 0. yiiveus. It often accompanies the latter 

 species in apple orchards and seems to be confined to ligneous plants, 

 such as trees or large shrubs. The eggs are deposited in the bark of 

 small twigs. 0. exclamationis, Davis, has been recorded from Staten 

 Island, New Jersey, New Haven and from parts of North CaroHna 

 and Ohio. The only known habitat on Long Island is the edge of a 

 natural prairie, where the dominant trees are Quercus marilandica and 

 Q. macrocarpa. 0. quadripunctatus is common in most parts of New 

 York State, with the exception of the northern forest areas. The
