constantly used the scale seldom becomes serious. Spraying should be 

 done from December to February and not too early in the winter. 

 Trees should be sprayed when slightly damp, and not wet. 



The pear thrips [Taeniothrips inconsequens] is a serious pest, but 

 a new material, " Nicodust," gives promise of being the most effective 

 remedial measure yet devised against it. A 5 per cent, strength is 

 recommended and should be dusted on the trees when the first thrips 

 appear in the spring. For an average prune tree one-third to one-half 

 of a pound will be sufficient, and the application should be made between 

 9 a.m. and 6 p.m. The dust volatilises best when the temperature is 

 fairly high. Other methods include irrigation after the crop has been 

 harvested to kill hibernating thrips. In the spring some growers leave 

 the cover crop until after the trees have blossomed, though this 

 materially reduces the moisture in the soil, and should only be prac- 

 tised where irrigation is possible. A liquid spray of 1|- per cent, oil 

 emulsion, adding 1 pt. Black-leaf 40 to every 200 gals, has also been 

 fairly satisfactory. 



State of Johore. Enactment No. 20 of 1921. — Appendix to Johore 

 Govt. Gaz., 29th December 1921, pp. 201-209. [Received 25th 

 February 1922.] 



The Agricultural Pests Enactment of 1914 is repealed and replaced 

 by the present Enactment, dated 21st December 1921, which provides 

 for the protection of trees, plants and cultivated products from disease 

 and pests. By the terms of this Act, the Sultan may from time to 

 time appoint officers with powers to enforce the Act, these officers 

 being empowered to enter and inspect any premises for the presence 

 of any pest or disease and to direct the destruction or treatment of 

 any plants affected by pest or disease or likely to harbour them. 

 Application may be made against the decision of the inspector to a 

 supervising committee. The powers of the court and the penalties 

 of non-compliance with the Act are enumerated. If considered 

 advisable, land may be placed under quarantine, or may be entirely 

 cleared of cultivation, and the provisions under which compensation 

 may be claimed for such action are explained. With regard to locust 

 invasions, inspection may be made for eggs or locusts, and it is incum- 

 bent upon the owner or occupier of land to report the appearance of 

 eggs or hoppers. The rules regarding the driving of locusts and 

 possible compensation for action taken are defined. The Act also 

 provides for the formulating of other rules made with the object of 

 prohibiting the entry of foreign pests or diseases and the treatment 

 or destruction of any infested material introduced. 



SiMMONDs (H. W.). The Big Spathe Boring Moth of Coconuts. — 



Agric. Circ. Fiji Dept. Agric, Suva, ii, no. 5, October-December 

 1921, p. 101. 

 A large spathe-boring moth of coconuts [a Cossid, Acritocera 

 negligens, Butler] is widely distributed throughout Fiji, where it 

 does much damage by destroying the j^oung inflorescence before 

 the bud opens. The egg is laid at the base of the spathe, and 

 the larva bores through and burrows up among the young flowers 

 and nuts, completely destroying those with which it comes in contact. 

 As many as eight have been found in one spathe.
