The campaign against Dociostaurus maroccamts in Capitanata 

 (province of Foggia) was begun in 1916 . As no definite information 

 could be obtained as to the areas where the eggs had been deposited, 

 about 5 tons of Cresosol and a number of sprayers were obtained for 

 the campaign against the adults in 1917. The appearance of these 

 was reported on 5th May and spraying with a 5 per cent, solution of 

 Cresosol was at once begun, the strength of the solution being increased 

 to 6, 7 and 7| per cent, as the locusts grew older. The stock of 

 Cresosol was exhausted on 19th May and sodium arsenite had to be 

 substituted, in solutions of 1, 2 and 3 per cent, strength. Spraying 

 was effected with Cresosol to kill masses of locusts and with sodium 

 arsenite to establish protective zones. Where water M^as not obtainable 

 in the neighbourhood, bran with the addition of 3 per cent, sodium 

 arsenite was used and proved very satisfactory. Bags of poisoned 

 bran were sent to small growers who required assistance. Cloth 

 bamers handled by gangs of women were also used for dealing with the 

 young adults, but were given up later on. The first deposition of 

 eggs was observed on 22nd June and an accurate survey was made over 

 an area of about 36 square miles. In one locahty D. maroccanus 

 was not found, but Callipiamus, Oedipoda and Stenobothrus were 

 represented. 



Cresosol has the disadvantage of injuring the rubber and leather 

 parts of the sprayers, while the prolonged handling of sodium 

 arsenite causes inflammation and burns. Sprapng furthermore 

 requires a considerable quantity of water, which is not always 

 available. Poisoned bran gave excellent results and eliminated this 

 difficulty. 



As a preventive measure for the 1918 campaign, the early destruction 

 of the eggs is advised. Cresosol is not recommended for the reasons 

 given, but the sodium arsenite spray and especially poisoned bran 

 should be employed.

This is the second note of a series on tliis subject [see this Review, 

 Ser. A, vi, p. 429]. From one locality orange leaves were received 

 infested with the scale-insects, Lepidosaphes heckii, Newm., Ckrysom- 

 phalus aonidmn, L., and Hemici donas pis aspidistrae, Sign. This last 

 is new to Chile and must be a, recent introduction. The termite, 

 Calotermes chilensis, was abundant in various parts of the country 

 in 1916.
