Deputy (O. D). Activities of the Federal Horticultural Board on the 

 Texas-Mexican Border. — Jl. Econ. Ent.. Concord, N.H., xiv, 

 no. 2, April 1921, pp. 178-183. 



The work of the inspection force on the Texas-Mexican border is 

 described. From 80 to 90 tons of potassium cyanide and 10 or 12 

 cars of sulphuric acid are used annually in fumigating cars infested 

 with cotton seed. The work also includes the inspection of passengers 

 to prevent the entry into Texas of quarantined products. 



O'Byrne (F. M.). Standardized Nursery Inspection. — //. Econ. Ent., 

 Concord, N.H., xiv, no. 2, April 1921, pp. 183-188. 



Suggestions are made for the standardisation of nursery inspection 

 requirements, so that unimportant variations and needless confusion 

 may be eliminated. Such an inspection service, to afford proper 

 protection, must provide, for instant use, a complete record of all 

 nursery stock moved with its sanction and permission. 



DiETz (H. F.). Some Problems in Greenhouse Inspection Work in 



Indiana. — //. Econ. Ent., Concord, N.H.. xiv, no. 2, April 1921, 

 pp. 188-194. 



If a grower is refused a certificate of inspection, he can ship green- 

 house plants by attaching a statement to them showing that they 

 are greenhouse-grown and, as such, do not come under the regular 

 nursery inspection requirements. The facility thus offered for the 

 spread of noxious insects and the resulting problems are discussed. A 

 list of insects and plant diseases is given, arranged according to their 

 prevalence in Indiana greenhouses. 



These include such important pests as the tropical ants, Prcnolepis 

 longicornis and Iridomyrmex humilis, which have not been recorded in 

 nature in Indiana.

Parrott (P. J.). Control of Sucking Insects with Dust Mixtures. — 



Jl. Econ. Ent., Concord, N.H., xiv, no. 2, April 1921, pp. 206-214. 



Experiments with dusting mixtures on a number of common sucking 

 insects showed that air currents, denseness of tree growth, low tem- 

 peratures and exudates of insects, such as wax and honeydew, exert 

 a greater adverse influence on dusting than on spra)nng materials. 

 With such pests as red-bugs and Aphids a thorough coating of the 

 insect is required to obtain satisfactory results. 



A dust containing 0-5 per cent, nicotine produced almost instant 

 paralysis of Lygidea menda.x. Rent, (apple red-bug) and was as quick
