 pp. 11-12 and 27. [Received 2nd June 1921.] 



No serious outbreaks of insects occurred during the year under 

 review on sugar-cane. The cotton worm [Alabama argillacea] was 

 prevalent during the latter half of the year, but the damage was greatly 

 reduced where poisons were at once applied. 



Cotton stainers [Dysdercus] were less injurious than in previous 

 years. In view of the benefit derived from the destruction of native 

 food-plants of these bugs, it is hoped that the campaign will be 

 continued.

This bibliography collates many of the articles published during 

 1913-1919 on Philippine and Malayan fungi and insects, all of which 

 are wholly or in part based on the biological field results obtained during 

 that time by the author.

An effective remedy against Nematodes infesting hyacinths and 

 narcissi is exposure of the bulbs for at least 24 hours to a temperature 

 of 113M15° F. (45°-46° C).

Repeated sprayings of the lower surface of the leaves with a |-1 per 

 cent, solution of barium chloride are effective against Aphids infesting 

 hops. The sprayed leaves must not be used for fodder. A solution of 

 tobacco refuse is also effective. Against mites, either the latter solution 

 or lime-sulphur spray may be used. The applications should be made 

 in the morning or in the evening, not in bright sunshine. 



Feytaud (J.). Sur la Protection des Edifices centre les Termites.— 



Rev. Zool. Agric. & App., Bordeaux, xx, no. 3-4, March-April 

 1921, pp. 17-23. 



The prevention of attacks of termites on houses by the careful 

 selection of materials to be used in building, as well as the various 

 methods of eradicating already existing infestations, are reviewed. 

 A successful experiment with chloropicrin as a remedial measure is 

 recorded.
