In and around Charlestown, South Carolina, an infestation was 

 reported to cover an area of 12 square miles and to be spreading 

 annually. 



In some cases, some of the chief root and vegetable crops have had 

 to be abandoned, and the cabbage industry is threatened. Poisoned 

 baits were not successful, probably because of the lateness of the 

 season, as they were not applied till October.

The Proctotrupid, Megaspikis craivfordi, sp. n., is described from a 

 nest of Formica exsecloides, Forel. This is the first species of its 

 genus to be recorded from ants' nests in America, but a number of 

 European species have been noted as myrmecophilous in habit.

Much of the work recorded for the year under review has already 

 been noticed in the Bulletins publishe(l by the Station. Experiments 

 against the woolly apple aphis [Eriosoma kinigerum] show that an 8 

 per cent, pine-tar creosote enmlsion apphed twice a year is efficient in 

 controlhng this Aphid and is not injurious to the trees, except where 

 the ground is such that the soil holds the creosote and natural water 

 around the trunk practically throughout the year. A number of new 

 insecticides have been and are being tried in the field, and the results 

 secured will form the basis of recommendations made to farmers 

 applying for insecticide material. Further experiments in the control 

 of Cgdia (Laspeyresia) fnolesla, Busck (Oriental peach-moth) [R.A.E., 

 A, vii, 254] indicate that orchards can be protected by thorough 

 spraying with a combination of self -boiled lime-sulphur, nicotine 

 sulphate and a satisfactory spreader, such as hme caseinate. In the 

 vicinity of the Experiment Station, 46 species of flea-beetles have been 

 collected and an amiotated list of them will be published. 



Experiments in dusting peach and apple trees indicate that insects 

 are controlled to about an equal extent as in liquid spraying, but that 

 diseases are not so easily checked.
