shoots of young tomato plants in the seed-bed, may be checked by 

 dusting the plants with ashes, air-slaked lime, or tobacco dust, or by 

 spraying with kerosene emulsion or tobacco decoction. 



The bulletin concludes with brief notes on the following insects, 

 which, in Florida, occasionally damage tomatoes : — Epicauta spp. 

 (bhster-beetles) ; Leptinotarsa decemlineala (the Colorado potato 

 beetle) ; Celerio lineata (w^hite-hned morning sphinx) ; Prodenia 

 eridania (semi-tropical army worm) ; grasshoppers ; the suck fly, 

 Dicyphus minimus, Uhl. ; Aleurodes tabaci (white fly of tobacco) ; 

 and the plant bugs, Nezara viridula, Euschistus variolarius, Lepto- 

 glossus phyllopus and Cicadula sp.

Laboratory work on Phthorimaea operculella showed that when seed 

 potatoes are dusted with equal parts of lime and Paris green, or lime 

 and lead arsenate, very few tubers became infested. Infested tubers 

 can be freed of these insects by fumigating with carbon bisulphide in 

 a closed bin at the rate of 3 lb. of the fluid to 1,000 cubic feet of space 

 for three hours without impairing the germinating powers of the seed. 

 Efforts have been made to find a less explosive substitute, and one of 

 these, " Antimont", is stated to be giving excellent results, especially 

 in keeping insects out of woollen goods and museum specimens. Against 

 red spiders [Tetranychus bimacidatus] on strawberry, the growers were 

 advised to spray with sulphur 20 lb., and caustic potash or caustic soda 

 10 lb., taking especial care to get the spray under the leaves. In 

 October and November, the San Jose scale was found to be causing 

 serious injury in E. and N.E. Texas, and spraying and pruning demon- 

 strations were given to the growers.

Among apple pests, Cydia pomonella, L. is found throughout the 

 state, causing losses from 40-70 per cent, of the crop. There are two 

 broods a year throughout the north part of the State and usually three 

 in the south. Spraying with lead arsenate paste (2 lb. per 50 U.S. gals.), 

 or powder lead arsenate (1 lb. per 50 U.S. gals.) is recommended, first as 

 the petals are falling, a second time three or four weeks later, a third time 

 eight or nine weeks after the petals have fallen, and a fourth 12 weeks 

 after the petals have fallen. Conotrachelus nenuphar, Hbst. (plum cur- 

 culio) should be sprayed with the following mixture: lime-sulphur, 

 3 gals., arsenate of lead paste, 5 lb., freshly slaked lime, 4 lb., to 100 

 U S. gals.water, applied first as the petals fall, repeated at intervals of 

 one week, three weeks, four weeks, and three weeks. Saperda candida,¥. 

 (round-headed apple-tree borer) works largely just below the bark. 

 Chrysobothris femorata, F. (fiat-headed apple-tree borer), a less serious, 

 though more common pest than the above, infests a variety of both 

 forest and orchard trees. The larvae attain maturity in one summer and
