211. Laboratory and office work. 



An important start has been made towards building up a general collection of 

 named material. 



212. Field work. 



A card index record is kept of all plantation inspections with cross references tO' 

 the field notes on the species observed and to the individual reports sent to the plan- 

 tations. The results of the cooperative experiments are filed under the species to 

 which they relate. 



213. Experimental work. 



In the experimental work on the May-beetles an effort has been made to introduce 

 natural enemies from abroad. An agent is working at the present tine in IlUnois on 

 the parasites of Lachnosterna in that locality. Various fungi have been introduced 

 from Hawaii, the United States and France^ The direct measures, in cooperation 

 with plantations, have included the use of insecticides, repellents and picking the 

 white-grubs behind the plows and the adults from their food plants at night. 



As regards the sugar-cane moth stalk-borer, Diatroea saccharalis, the egg parasites 

 of the same in Louisiana, Mexico and British Guiana are sought. An agent visited 

 Mexico last season but was forced to return to the United States on account of the 

 political disturbances. The direct measures against this borer include experi- 

 ments on seed selection, seed treatment, covering of seed, plucking out of "dead'* 

 hearts, and the destruction of the trash after harvest. 



The experimental work on the mole-cricket, Scapieriscus didaciylus, includes 

 different systems of planting the cane, cutting to prevent injury and trap light 

 experiments in capturing adults at night. 



The work under this heading against the sugar-cane mealy-bug, Pseudococcus sac- 

 chari, relates to the treatment of seed before planting and seed selection. The lady- 

 bird beetle, Cryptolaemus montrouzieri , a mealy-bug feeder, has been introduced 

 successfully from California, through the Audubon Park, New Orleans, laboratory 

 of thf^ United States Bureau of Entomology and has been bred and liberated through- 

 out the cane areas in large numbers.

214. Endoparasitism. 



Substantial progress. Not yet ready to report. 



215. Bud weevils. 



Quite lately a series of over a dozen species of weevils has been troubhng the fruit 

 growers of the Columbia River basin, and elsewhere, by destroying the buds of young 

 trees early in the spring. The damage often has been serious. A concern near Brew- 

 ster has been manufacturing tree collars of enameled tin to protect against the 

 weevils ascending. ,
