be had against the apple root-borer by treating the trunks at about 

 the time fruit is setting in the spring. The egg-laying season is of 

 short duration and temporary wrappings of paper or burlap, or any 

 other material that will entirely cover the lower 2 feet of the trunk 

 for a period of 4 or 5 weeks following the blooming season of the 

 apple, will in a large measure prevent the eggs from being laid on the 

 bark. Treatment with sticky material or heavy paints will answer 

 the same purpose. The common service tree in proximity to an apple 

 orchard should always be regarded as a source of possible infestation, 

 as the pest develops freely in it. 



Weiss (H. B.). Insects found on Nursery stock Imported into New 

 Jersey during 1913. — Entoni. News, Philadelphia, xxv, no. 9, 

 November 1914, pp. 392-395, 2 charts. 



According to C. L. Marlatt, in 1912 there were imported into the 

 United States 44,781 cases of nursery stock, of which about one-fifth 

 entered the State of New Jersey. A list of the insects, therefore, 

 which were imported on stock entering New Jersey during 1913 is of 

 interest to those engaged in inspection work in other States. As a 

 rule, it is difficult during the inspection season to ascertain what is 

 taking place in other States and some system of co-operation, whereby 

 the different inspectors could be informed of such happenings, would 

 be of value in putting them on their guard against certain species. 

 Two charts appended to this paper indicate the total importations 

 of nursery stock into New Jersey, most of which came from Holland 

 and Belgium. 



During the spring the following species were intercepted : — 

 Pseudaonidia faeoniae, Ckll., on azaleas from Japan ; Pseudococcus 

 azaleae, Tins., on azaleas from Japan ; Parlatoria pergandii, Comst., 

 on maples from Japan ; Diaspis pentagona, Targ., on Primus persica 

 from Japan ; Aspidiotus hederae. Vail., A. hrilannicus, Newst., and 

 Coccus hesperidum, L., on bay trees from Belgium. 



During the autumn the shipments infested were as follows : — 

 Aleurodes sp., on azaleas from Belgium and Holland, on aucubas 

 from Holland, and on bouvardias from England ; Lepidosaphes 

 ulmi, L., on boxwood from Holland ; Tingitidae eggs on rhododen- 

 drons fiom Belgium ; Coccus hesperidum, L., on bay trees from 

 Belgium ; Pseudococcus sp., on palms and bays from Belgium, on 

 Metrosideros from Belgium, and on bamboo canes from England ; 

 Chrysomphalus aonidum, L., and C. dictyospermi, Morg., on palms from 

 Belgium ; Aspidiotus hederae. Vail., on oleanders and palms from 

 Belgium and on Yucca tricolor from England ; Diaspis boisduvalii. 

 Sign., on orchids from England ; Hemichionaspis aspidistrae, Sign., 

 on ferns from Belgium and England ; the Stratiomyid, Sargus 

 (Macrosargus) cuprarius, L., the Hemipteron Salda (Acanthia) 

 saltatoria, L., and the Tineid moth, Gracilaria azalea, Busck. on azaleas 

 from Belgium; Peripsocus sp., on bay trees from Belgium; Apion 

 ulicis, Forster, in seed-pods of Ulex europca from England. 



Practically all the insects, with the exception of the species of 

 Aleurodes, are alreadv more or less widely distributed in the United 

 States. The infested plants received during the spring from Japan 

 were destroyed, while the bay trees were cleaned by the consignees
