South (F. W.)- A Summary of Locust Work in 1915. — Agric. Bull.

This report summarises the -work done in controlling locusts during 

 the year 1915, much of which has already been reported separately 

 [see this Review, Ser. A, iv, p. 122, v, pp. 36]. 



The decrease in the number of locusts in the coast district has been 

 very noticeable. The Tampin district has provided the most work, 

 and efforts have been concentrated there in order to reduce as far as 

 possible the number of locusts breeding on the lalang country to the 

 east and north of Tampin. 



In Johore there was no destruction work during the first quarter 

 of the year. The locusts in this State have been confined throughout 

 to the northern end and have been kept fairly under control. 



In Selangor 202 swarms were destroyed in 1915, as compared with 

 3,118 in 1911. In Negri Sembilan a total of 6,071 swarms wQjre 

 destroyed as against 4,212 in 1914. This increase is due to the use 

 of the poison method throughout the year in all places where it could 

 be employed without danger and thus shows added efficiency in the 

 work. In Johore the number of swarms destroyed was 1,505, which 

 with those destroyed in the Federated Malay States gives a total of 

 7,778 swarms as compared with about 7,930 swarms in 1914. No 

 locusts bred in Pahang in 1915. The cost of control work in 1915 

 was £6,586 as compared with £9,466 in 1914. This reduction 

 in expenditure was due to the small amount of destruction work in 

 Selangor, the use of the poison method, and also to the reduction in staft". 



The amount of damage done by the locusts has been practically 

 neghgible. It is anticipated that in the coming year the locusts in 

 Selangor will only occur as an occasional swarm flying northwards, 

 while those in Negri Sembilan will be mainly confined to the Tampin 

 district, and Tankak vdW remain the chief centre in Johore.

The control measures for scale-insects on evergreen trees including 

 citrus recommended in this paper are : spraying with a weak 

 red-oil emulsion, lime-sulphur, or resin w^ash, or fumigation, the 

 last being the most successful method. The trees should be enclosed 

 in an air-tight sheet or tent. A wooden, enamel or earthenware vessel 

 is placed inside the tent containing a mixture of 4 fluid oz. sulphuric 

 acid and 12 fluid oz. water, the acid being placed in the vessel first ; 

 4 oz. of cyanide of potassium are then quickly dropped into the vessel 

 and the tent closed at once ; the bottom of the tent should be covered 

 with soil to prevent any of the gas escaping. Fumigation should be 

 carried out at night or on a cloudy day, when the foliage is quite dry.
