 Osbourne). — Agric. Gaz. N.S.W., Sydney, xxxi, no. 7, July 1920, 

 pp. 502-506, 8 figs. 



The grass thrips, Anophothri'ps striatus, Osb., here redescribed, is 

 recorded as causing serious damage to tobacco in Australia. On 

 25th April 1919 all stages were found on the upper and lower surfaces 

 of tobacco leaves. , . -^a^^'"'*" '*' 



The remedial measures advocated include spraying with a soda soap 

 wash during the earlier growth of the plants, and destruQtioi£)l^ \ 4 

 ploughing or burning of all plants and waste material in the paddock 

 aitev the tobacco has been cut and removed. Burning sulphtlf^ftt^^j 

 the windward side of the tobacco plants was of no use and caused 

 •scorching of the foliage. 



Froggatt (W. W.). To destroy the Mole Cricket. — Agric. Gaz.,N.S.W. , 

 Sydney, xxxi, no. 7, July 1920, p. 518. 



A bait consisting of 1 oz. Paris green, 16 oz. bran, one tablespoonful 

 salt, and sufficient water to bring the whole to the consistency of bran 

 mash, is advocated for the destruction of mole-crickets, Gryllotalpa sp. , 

 in such places as garden lawns and putting-greens. They may also 

 l)e drowned bv flooding.

 Toronto, xliii, no. 8, August 1920, p. 220. 



Grasshoppers were unusually abundant in Ontario in 1920. In 

 most cases they spread from old pastures and waste land to cultivated 

 iields, causing serious injury to the crops. The remedial measures 

 suggested are autumn or early spring ploughing, and the use of a poison 

 bran bait consisting of 20 lb. bran, -| to 1 lb. Paris green, 2 qts. molasses, 

 2 or 3 oranges or lemons and 2 gals, water. A clieaper substitute may 

 I'C made with 20 lb. sawdust, ir to 1 lb. Paris green, -| lb. salt and 2 gals, 

 water. This mixture will only be sufficient for about 3 acres, whereas 

 the bran bait will cover 4 acres. 



Illingworth (J. F.). Cane Grub Investigations. — Queensland Agric. 

 Jl., Brisbane, xiv, no. 1, July 1920, pp. 35-36. 



Since the cessation of delayed but heavy rains in North Queensland, 

 which prevented the sugar-cane from making much advance, the 

 activities of the cane-grubs {Lepidiota alhohirta) have been very notice- 

 able. Within four days the whole infested area yellowed, and, in places, 

 the leaves turned brown as if scorched. To make matters worse the 

 grubs will continue feeding several weeks later than usual before hiber- 

 nating, owing to their having hatched so late. A small area, formerly 

 free from them, is now infested, apparently because the fowls, which 

 used to occupy it and destroyed great numbers of the egg-laden 

 beetles, were disposed of before the flight of the beetles. In all, 

 several hundred acres of fertile soil have been consequently thrown 

 out of cultivation.
