plum aphis) is a widely distributed species injurious to plum and 

 apricot. It migrates from the plum in late summer to reeds and 

 returns to plum in the autumn, when sexual forms are produced. 

 Eggs are laid on the phxm which hatch in the following spring and 

 give rise to wingless females, each of which founds a new colony. 

 Spraying should be done in early spring before the leaves have curled 

 and form a protection from the liquid. Paraffin emulsion or paraffin 

 jelly is recommended, with the addition of hver of sulphur in the 

 proportion of 1 lb. to each 100 gals, of spray. 



Hylemyia coardata (wheat bulb fly) continues to be responsible for 

 considerable loss of wheat, the complete life-cycle of this pest being still 

 unknown. It is difficult for this reason to advise remedial measures, 

 but it is thought that cultural methods may prove more helpful than 

 destructive measures against the larvae. It is considered inadvisable 

 to follow a potato crop with wheat in districts where the pest is 

 prevalent. Chortophila brassicae (cabbage root fly) is a well-known 

 pest of cabbages, cauliflowers, radish, broccoli and turnip. The use 

 of tarred felt paper discs is still considered the best remedy for this 

 pest. Hydroecia micacea (rosy rustic moth) is a Noctuid attacking 

 many wild plants, while cultivated plants, such as hollyhock, hops, 

 tomato fruits and potatoes are also damaged by it. 



Furniture beetles include Anobiiim domesticum, which oviposits in 

 chinks in the wood, the larvae tunnelling into the wood and partially 

 emerging again to pupate. Xestohium tessellatum is found out-of-doors 

 as well as in furniture. Furniture infested with these species should 

 be fumigated with sulphur dioxide, or the holes may be treated indi- 

 vidually with parafiin applied with a syrmge having a very fine nozzle. 

 A temperature of 125° F. would kill the insects in all stages. The 

 wood may also be painted with naphthaline 780 grs., corrosive 

 sublimate 80 grs., methylated spirit 1| pints. Sitodrepa panicea is 

 destructive to food-stuffs such as flour, biscuits, coffee, beans, various 

 drugs, and spices; leather, books, manuscripts and pictures are also 

 attacked. Fumigation with carbon bisulphide is recommended. 

 Monotnorium pharaonis (red or yellow house ant) frequently infests 

 houses in Britain, feeding upon foodstuffs, as well as being carnivorous. 

 Its numbers can be checked by traps, but this is a tedious method. 

 Tables on which food is kept should be placed with the legs set in 

 vessels of water. The only satisfactory measure is the destruction 

 of the nests, but these are frequently inaccessible in buildings. 



RiGGS (W. M,). Report of the South Carolina Boll Weevil Commission. 



S. Carolina Agric. Exjjt. Sta., Clemson College, Bull. no. 20, 

 23rd November 1916, 23 pp. 



This report reviews the conditions as regards Anfhonomus grandis 

 in other States and discusses the inevitable results of the probable 

 introduction of this weevil into South Carolina. Intelligent co- 

 operation amongst the community is urged, in order to make all 

 possible provision for meeting the first year of weevil infestation and 

 to prevent disaster due to the initial panic following the first crop 

 failure. The general aspects of the boll weevil question dealt with 

 include the life-history of the pest, the record of its spread in the 

 United States, climatic and other conditions of South Carolina as
