A Pest of the Horse Bean. Agric. Neics, Barbados, xv, no. 379, 

 4tli November 1916, p. 363. 



Caterpillars of Anticarsia {Thermesia) digitalis are reported in 

 Grenada as attacking the foliage of horse-beans. Lead arsenate might 

 be used, if worth while, but a preliminary experiment would be needed 

 to find what strength was non-injurious to the plants.

The action of this apparatus depends upon a habit which this fly 

 [Agromyza phaseoli] has of making a rapid upward flight when disturbed. 

 In its simplest form it consists of a sheet of window glass set in a light 

 wooden frame, with a curtain of calico about 6 in. Avide attached to 

 three of its sides and a pair of wooden handles on the upper side. The 

 under side of the glass is lightly sprinkled with kerosene, which spreads 

 into a thin film over the glass. The frame is then carried over the 

 young bean plants with the ojjen side in front, and about 9 or 

 10 in. from the ground, the rear part of the glass just clearing the 

 young plants. The advancing sheet of glass passes over the flies before 

 they rise, and as they do so directly upwards, they strike the glass, 

 become saturated \vith kerosene and die instantly. A larger horse- 

 drawn apparatus, constructed on a similar plan, is suitable for larger 

 areas. After about nine days the flies are less destructive, and as they 

 prefer young beans, a good trap may be prepared by sowing a row of 

 beans in the near vicinity 9 or 10 days after the crop is planted. 



Red Oil for the Red Spider. — Queensland Agric. JL, Brisbane, vi, no. 4, 

 October 1916, p. 255. 



The best remedy for fruit attacked by this pest is an application of 

 red oil emulsion, either in winter or early spring. Late spraying has 

 proved both feasible and successful. Oils applied when the fruit buds 

 are swelling stimulate the tree and are very effective against the mites. 

 If they are present on the leaves during the summer, a lighter-bodied 

 oil may be used, which must be plentifully mixed with soaj) to render 

 its application safe.

The annual campaign against locusts began in March and was carried 

 on throughout April and the whole or part of May in the district of 

 Tampin and in Malacca and Johore. Tables are given showing the 

 number of swarms in the various States, the localities in which they 

 occurred and the number of swarms poisoned. A considerable number 

 of flying swarms escaped, largely owing to the shortage of labour in 

 certain centres. The weather during the quarter under review appears 

 to have been very favourable to locusts, and in spite of the destruction 

 of large numbers of hoppers, the winged swarms in the Tampin disteict,
