B[allou] (H. a.), a Wood-boring Moth.— Agric. Nei£.'s, Barbados, 

 xxi, no. 517, 18th February 1922, pp. 58-59. 

 The life-history of Duomitus punctifer, Hmps., which occurs 

 throughout the Lesser Antilles, and some of its food-plants have already 

 been noticed [R.A.E., A, iii, 73]. Other food-plants include orange, 

 tangerine, Grevillea and MalpigJiia. This Cossid only attracts attention 

 at intervals, its attacks being more severe in dry seasons and usually 

 on trees that for various reasons are not thriving. Remedial measures 

 include heavy pruning of severely attacked trees (care being taken 

 that all the branches containing larvae and pupae are promptly 

 burned to prevent their further development), probing the tunnels 

 with a wire to kill the borers and fumigating with carbon bisulphide. 

 These last two methods are difficult to apply to tall trees.

The new Cecidomyiids described are Camptomyia ricini, reared 

 from dry castor-bean stems {Ricinus communis) ; Asphondylia 

 pongamiae, which produces galls on Pongamia glabra and is parasitised 

 by a Chalcid ; Contarinia andropoginis, reared from the ear-heads of 

 cholam {Andropogon sorghum) ; Itonida seuiinis, reared from ear- 

 heads of cumbu (Pennisetmn typhoideum) ; and Cecidomyia artocarpi, 

 reared from rotting jak fruit [Artocarpus).

 1922, p. 87.' 



An account is given of spraying about 5,000 acres of land heavily 

 infested with large swarms of grasshoppers. About 3,000 gals, of a 

 spray containing 1 lb. sodium arsenite, 4 lb. molasses and 16 gals, 

 water were used. Logs, thistles and other likely shelters were success- 

 fully sprayed, as well as the egg patches. At one period petrol and 

 kerosene were used, but this was abandoned as less economical. 



Ziekten en Plagen der Cultuurgewassen in Midden- Java in 1921.

A severe infestation of Helopeltis occurred on cacao, and the carefully 

 arranged introduction of ants did not have uniform success. The 

 cacao moth [Acrocercops cramerclla] also occurred in large numbers, 

 but experiments against it, including the use of natural enemies, 

 do not yet warrant the pubhcation of results. The gramang ant 

 [Plagiolepis longipes] proved a great nuisance on one estate. 



The coffee berry beetle [Stephanoderes hampei] occurred in places. 



Pests of Hevea included termites, which were, however, of little 

 importance in general as a result of the plantations being well looked 

 after.

Inst, landw. Forsch.. Kttrascliiki, ii, no. 1, 1922, pp. 1-20. 



In these experiments, conducted in 1917 and 1919, the author 



prepared two kinds of lime-sulphur, one in which equal amounts of 



lime and sulphur were used, and the other in which the amount of
