 C. A. Pearson Ltd., 1919, 202 pp., 44 plates. Price 3s. U. 

 [Received 14th Sept. 1920.] 



This book gives a popular account of the insect pests that are most 

 likely to be met with in Britain, in the farm — including those that attack 

 farm animak — garden, orchard or greenhouse, and of the remedial 

 measures that may be used against them. Special attention is given 

 to methods of ' treatment that are practicable for a small holder. 

 Fungus pests are also noticed, and there are chapters on soil com- 

 position and manures. There is an adequate index, and also a chart 

 showing the insect pests that may be expected, and the work that 

 may be necessary, from month to month. 



AsHBY (S. F.). Black Fly on Citrus Trees. — Jl. Jamaica Agric. Soc, 

 Kingston, xxiv. nos. 3 & 6-7, March & June July 1920, pp. 72-74 

 & 182-184. 



In this report on black fly [Aleuroccmthus woglumi] on orange, 

 grapefruit and tangerine trees in various districts of Jamaica, the 

 conditions of the various districts are considered in detail. The 

 spread of the fly is slowly followed by the red and brown fungi [As- 

 chersonia cdeurodis and Aegerita webberi] that attack this pest ; early 

 infestations of the fly are liable to be heavy, but are reduced when the 

 fungi become estabhshed. The fly is controlled at the lower elevations 

 bv an ant [Cremastogaster], which also keeps the trees free from scale 

 insects. This ant and a small black stinging species seem to be 

 mutually exclusive, and colonies of the latter in trees should be des- 

 troyed with oil emulsion, before any attempt is made to introduce a 

 colony of the beneficial species.
