58 EXPERIMENT STATION RECORD. 



under 18 in. or more of water at a teniiierature of v>{\" V. Reflooding of the beds 

 for 24 hours after the ejrgs have hatched will destroy nearly all of the larvfe. It 

 appears that the natural enemies of the cottony maple scale may be largely 

 depended upon to control this pest. Brief notes are given on the results of 

 j)ractical tests with a number of proprietary insecticides. 



A report is given on the mosquito investigation during 190.5 (pp. 6.5.5-089). In 

 this work particular attention was given to determining the beneficial results 

 from previous drainage work and other remedial measures and a further sur- 

 vey of the study to determine the work still to be done. Estimates are given of 

 the cost of operations which will be carried on in utilizing the State appropria- 

 tions for mosciuito work. 



Report of the government entomologist, C. Fuller {Xatcil Dept. Af/r.. Rpt. 

 Govt. Ent., Ji ( 1!H)3--'/. pp. .'/?, pU, ,S'. flijs. 3). — A general account is given of the rou- 

 tine work of the ottice with notes on lectures given by the entomologist and travel 

 done in various parts of the colony. An unknown species of Carpocapsa is 

 referred to under the name of Natal codling moth and brief notes are given on 

 its habits. It attacks peaches, Chinese guavas. oranges, and mandarins. The 

 pest may be partly controlled by removing infested fruits, but spraying with 

 Paris green combined with Bordeaux mixture is also of great value. An account 

 is al.so given of the true codling moth, fig curculio (Mctatyges turrit us), mango 

 weevil, Bengalia deprcssa which attacks man, dogs, rabbits, and other animals ; 

 Mediterranean fruit fly, mosquitoes, Bacpada hilaris. scale insects, locusts, rhu- 

 barb blight, English sparrow, and various other pests. Formulas are also pre- 

 sented for the prep.-iration of certain insecticides. 



Report of the government entomologist, C. Fuller (\(ttiil Drpt. Af/r.. lipt. 

 Govt. Ent., ') (190Jf-5), pp. 17, pL 1). — The routine inspection and other work of 

 the office for the year is brieflj^ described. A statement is also given regarding 

 the investigation of fruit fly parasite. It is believed that the parasite which 

 has been found in Brazil does not promise to be of much assistance in the con- 

 trol of the fruit fly. Copies are also given of certain legislation relating to 

 plant diseases, cotton diseases, weeds, fruit inspection, etc. During the year 

 under report arsenical insecticides were extensively used in the control of 

 locusts, and this work gave good results. 



Entomological division, W. R. Dewar (Oraiuic Rirer Colony, Dcpt. Af/r., 

 Ann. Rpt., 1 {190Jt-5). pp. 1S3-238, fl(/s. /«).— The matters discussed in this 

 report include the use of arsenicals and other methods for combating locusts, 

 the inspection of nursery stock so as to prevent the introduction of injurious 

 insects, the distribution of lady beetles, the investigation of mosquitoes and ticks, 

 as well as a large vai'iety of insects injurious to garden and field crops. A 

 brief account of birds as related to agriculture is given by C. M. .lohnston 

 (pp. 221-228), and the subject of injurious weeds is also discussed (pp. 229-238). 



The entomological section, C. R. Simpson iTrun.^raal Af/r. Jour., .', {1906), 

 No. 1.), pp. C)l9-62(). Ills. '/). — Ophiitsa catcUu is injurious during its larval stage 

 to the leaves of Ciistoi--oil beans while the adults puncture peaches, thereby 

 greatly injuring the crop. Notes are given on the insect in its various stages 

 and on its natural enemies. In small plantations of castor-oil beans hand- 

 picking is quite satisfactory, while on large plantations si)raying is necessary, 

 and for this purpose Paris green or some other arsenical is reconuuended. 

 Notes are also given on IJcUocopris liainad) yas and the cigarette beetle. 



Report on injurious insects in Finland, E. Reuter {lAindthr. ^tyr. Meddel., 

 50, 1905, pp. 27). — The year under report was unusually cloudy and cold and 

 therefore somewhat unfavorable to the multiplication of insects. As in previous 

 reports, the author classifies his discussion of injurious insects according to the 

 plants affected. Grasses of pastures and meadows were injured to some extent
