This article records the infestation of mandarin oranges by scales, 

 said to be LepidosapJies heckii {Mylilaspis citricola) and Coccus 

 {Lecanium) hesp)eridum. A kerosene-soap emulsion is the control 

 advised.

The ravages of the olive fly [Dacus oleae] still continue unchecked, 

 in spite of the various controls adopted. In the low-lying coastal 

 districts, this insect appears earlier and completes a larger number of 

 generations than in the hilly regions. The destruction of all early 

 varieties of the olive in the coastal districts would therefore reduce 

 the opportunities of breeding of this pest. Later in the season, the 

 danger of infestation diminishes, as olives are not attacked when they 

 are sufficiently mature to begin to contain oil.

This article is an abstract from the author's original in V Agricoltura 

 Pisana. The existence of Phlocothrips oleae is dependent upon that 

 of Phloeotribus scarabaeoides, Bern, {oleae, F.), as it hibernates in the 

 galleries of the latter. Control of the Scolytid should therefore prove 

 effective against both insects.

In the districts of Selangor and Negii Sembilan and in the State of 

 Johore, 351 swarms were taken with the bag-trap, the locusts filling 

 5,220 petroleum tins. A further 449 swarms were poisoned in Negri 

 Sembilan. These figures cover the first three months of 1915.

During 1914, 68,487 four-gallon kerosene tins of hoppers were 

 destroyed in the districts of Selangor, Negri Sembilan and Pahang. 

 These represented 4,218 swarms. In addition, 3,392 swarms were 

 poisoned and a further 250 swarms were destroyed at Temerloh. 

 The total cost of the work for the year was £9,406 against an estimated 

 expenditure of £12,250. The expenditure included the cost of the 

 necessary sprayers and of the repairs and replacei:uent of all tlie
