although it can not be regarded at present as seriously menacing 

 strawberry growing in Florida. As remedies kerosene emulsions and 

 pyrethruin are noted. 



The leaf-footed plant bug (Leptoglossus phyllopm) not infrequently 

 attacks the strawberry, sucking the fruit and tender shoots, some- 

 times doing considerable damage, though its usual food plant in Flor- 

 ida appears to be the thistle Carduus spinosissimus. Nymphs were 

 observed on the Irish potato. Hand picking is recommended. 



The negro bug {Corimelcena pulicaria), although more abundant in 

 Florida on blackberries, also frequently does considerable damage to 

 strawberries, the injury being mostly due to the odor it imparts to the 

 berries. Hot water (155° F.) is noted as a remedy. 



Cutworms, principally Agrotis ypsilon, are frequently abundant. One 

 grower gave the information that he had dug out COO daily for a week: 

 another that he found 40 near a single plant. 



The remaining insects noted are white grubs (Lachnostenia spp.), 

 strawberry flea-beetle (Haltica ignita), grasshoppers, crickets, the 

 strawberry weevil, the strawberry crown borer [Tyloderma fragaruc), 

 and strawberry-leaf roller (Phoxopteris comptana). The last 2 insects, 

 however, have not yet been found in Florida. The life history of //. 

 ignita is thought to be somewhat similar to that of the grapevine flea- 

 beetle. No record is known of the larva' feeding on the leaves of the 

 plant, and it is regarded as possible that they attack the roots. 



Two spraying machines are figured. 



Some injurious insects of the orchard, E. E. Faville and P. J. 

 Parrott (Kansas Sta. Bui. 77, pp. 25-62, figs. 32). — This is a popular 

 discussion of the following insects, including descriptions, lite histories, 

 habits, injuries, remedies, etc.: Cankerworm (Paleacrita vernata), cod- 

 ling moth (Carpocapsa pomonella), tent caterpillar [Glisiocampa ameri- 

 cana), plum curculio (Conotrachelus nenuphar), plum gouger ( Coccotorus 

 scutellaris), peach-tree borer (Sannina exitiosa), flat-headed borer (Chrt/s- 

 obothris femorata), round-headed borer (Saperda Candida), San Jose 

 scale (Aspidiotuspemiciosus), and elm-twig girdler ( Onrideres cingulatus). 



The spring cankerworm has steadily spread into the fruit regions of 

 the State until now it is regarded as one of the leading orchard pests. 

 The insect attacks forest and shade trees as well as fruit trees. The 

 remedies suggested are to prevent the wingless female from ascending 

 the trunks of trees, and to spray the trees with poisons. The first may 

 be done by the use of sticky mixtures, such as printers' ink, piue tar, 

 resin and castor oil, dendrolene, raupenleim, etc., applied as a band to 

 the trunk of the trees or by the use of collars of tin, paper, etc., fas- 

 tened about the trees. The author gives the following summary of 

 results of spraying : " Trees sprayed with Paris green were not scalded ; 

 loss from the work of larvae from 1 per cent to 5 per cent. Trees sprayed 

 with soluble arsenic solution showed leaves scalded 5 per cent, larvae 

 completely destroyed. Trees sprayed with insoluble arsenic solution 

 showed leaves free of scald, 1 per cent of leaves destroyed by larva?."
