Used as a stomach poison against Leptinotarsa decemlineata, Say 

 (potato beetle) at strengths ranging from 1 lb. of powder to 16 gals, 

 of water up to 1 lb. to 128 gals, it killed all larvae within 48 hours. 

 Other insects against which it proved effective include Malacosoma 

 americana, F. (tent caterpillar), Hyphantria cunea, Dru. (fall web- 

 worm), Anisota senatoria, S. & A. (oak worm), Datana ministra, Dru., 

 and Phytometra {Autographa) hrassicae, Eiley (cabbage looper). Some 

 insects are more easily affected than others, but apparently death 

 eventually occurs in all cases through motor paralysis. The toxic 

 principle is probably a resin.

The damage caused by the cotton boll weevil [Anthonofnus grandis] 

 in Georgia during the year under review resulted in the reduction 

 of the crop by as much as 50 per cent, in some counties. Maps are 

 given shomng the extent of the territory covered by this pest. Various 

 experiments were made during the year to control the weevil by means 

 of dusting with lead arsenate, calcium arsenate and Lazal, together 

 with sulphur and Imie in each case. The results obtained seem to 

 indicate that late dustings are preferable to early ones, but more 

 extensive experiments, for which plans have already been made, are 

 needed to confirm these observations. 



New pests recorded during the year included a species of Margarodes 

 and the chrysanthemum midge {Diarthronomyia hypogaea) which was 

 apparently introduced with chrysanthemums from Indiana.

In 1917 the damage caused by the boll weevil [Anthonomus grandis] 

 in Georgia amounted to from 25 per cent, to 75 per cent, of the crop. 

 A map showing the infested area and the determination of the 20 

 mile safety line is given. The regulations governing transportation 

 of cotton seed, seed cotton, hulls, seed cotton and cotton pickers' 

 sacks, etc., directed against the spread of this pest are recapitulated 

 and brought up to date [see this Review, Ser. A, iv, p. 435].

Owing to severe drought in January, tea pests, especially Calotermes 

 militaris and various mites, appeared in great abundance ; the latter 

 were dealt with by spraying with Ume- sulphur. The fluted scale 

 [I eery a purchasi] was kept in check by the fungus Cephalosporium. 

 Consignments of the Coccinelhd enemy of this scale [Novius cardinalis]
