Hunter (A. T.). An Earth Pit for the Destruction of Fly-infested Fruit. 



— Agric. Gaz. of New South Wales, Sydney, xxvi, no. 10, October 

 1915, pp. 889-890, 2 figs. [Eeceived 10th December 1915.] 



A pit for the destruction of fly-infested fruit in orchards is dug 

 about 18 inches wide, 6 feet long and 4 feet deep. The top, except 

 for about 10 inches at one end, is covered with a sheet of iron. A fire 

 is made at the bottom of the pit and the waste fruit filled in from above. 

 An incinerator built of brick, stone or concrete, suitable for level 

 ground, should be about 4 feet by 2| feet inside and 4 feet high. Iron, 

 bars are built in 1 foot above the ground level. The fire is made under 

 the bars and the fruit put in from above.

 Ottawa, ii, no. 11, November 1915, pp. 1055-1056, 3 figs. 



In June 1915, a Chalcid was found destroying the eggs of Crioceris 

 as'paragi, L. (asparagus beetle) at Vineland Station, Ontario, which 

 has been determined as Tetrastichus asparagi, Cwfd., a species not 

 previously recorded from Canada. Its work at Vineland was so 

 effective that spraying was not required. 



Watson (J. R.). Cyanamide as a Means of controlling Root-Knot.— 



Florida Grower, Tampa, 9th October 1915, pp. 16-17. [Received 

 7th December 1915.] 



The value of cyanamide in the control of soil pests, especially 

 Nematodes, was tested by the application of from 600 to 1,0001b. 

 per acre ; it was thus found possible to grow some kinds of susceptible 

 plants on heavily infected soil. Used in large quantities, a compound, 

 dicyanamide, was formed, which was more stable and therefore 

 injurious to the growth of some plants. The Nematodes could not 

 however be entirely exterminated by the use of cyanamide. 



Brock (A. A.). Fumigation in Ventura County and its Cost. — Mthly. 

 Bull. Cal. State Commiss. Hortic, Sacramento, iv, no. 11, November 

 1915, p. 522. 



Fumigation of citrus plantations should be carried out, where 

 hatching of scale-insects takes place evenly, between 1st September 

 and 1st January. Where hatching is uneven, it should be undertaken 

 when it is possible to kill the largest percentage. An early fumigation, 

 followed by a later one, may give good results in such a case. The 

 length of time between fumigations depends largely on the uniformity 

 of the hatching. If properly carried out, once every two years should 

 be sufiicient. The average cost for large trees is about one shilling 

 per tree.

Two Coccinellids recently introduced into California from Italy 

 against scale-insects, are Chilocorus bipustulatus, L. and Exochomus
