two generations a year in Georgia. The winter is passed in the ground 

 in the pupal stage ; the second brood of larvae hatches out late in 

 June, and the pupae of this generation emerge as adults in the following 

 spring. The tomato horn worm, Protoparce (Phlegethontius) sexta, 

 is normally controlled by parasites. The eggs are deposited on the 

 under surface of the leaves of tomato, tobacco, egg-plant, etc. The 

 larvae are subject to a bacterial disease. Dusting or spraying with 

 lead arsenate is an effective remedy. Deep autumn and winter 

 ploughing is advisable. Chloridea {Heliothis) obsoleta attacks cotton, 

 tomatoes, corn and beans. Winter-ploughing destroys hiberna-^-^^i^ 

 pupae ; direct remedies, such as spraying, have not proved successful. 

 The three important cabbage worms are Phytometra {Autographs) 

 brassicae, Pieris (Poiitia) rapae and P. protodice. The Colorado potato 

 beetle, Lepfinotarsa decemlineaia, Say., is common throughout the 

 state. Diabrotica vittaia, F., attacks cucumber and related plants. 

 Cloth or netting is satisfactory in protecting the plants from attack. 

 Spraying with Bordeaux mixture or dusting with a mixture of Paris 

 green and air-slaked lime, gives good results. Epitrix cucumeris can 

 be controlled by the use of Bordeaux mixture. A number of formulae 

 for the preparation of spraying mixtures and a brief description of 

 spraying pumps now in use, are given.

Brown rot and plum curcuho {Conotrachelus nenuphar), on peaches 

 and plums, are best controlled by the use of self-boiled lime-sulphur 

 mixture and arsenate of lead. The Hme-sulphur is prepared as follows : 

 81b. fresh lime are covered with cold water and to this is gradually 

 added 8 lb. sulphur. The mixture is stirred constantly and diluted to 

 a thin paste. The slaking of the lime supplies sufficient heat to boil 

 the water for several minutes. When cool, the mixture should be 

 strained and diluted to 50 (U.S.) gals. Arsenate of lead is added at the 

 rate of 2 lb. to 50 gals, of mixture. The first apphcation should be made 

 2-4 weeks after the petals fall. A month later, hme-sulphur should 

 be used alone. Both upper and under sides of the leaves should be 

 sprayed.

Lachnosterna sp. has been recorded from many parts of Mississippi 

 as a pest of young pecan trees. The leaves and buds are eaten at night 

 by the adult beetles. Control measures consist of frequent ploughing 

 to destroy larvae and pupae, collection at night, and spraying with 

 lead arsenate or Paris green. Pigs destroy large numbers of the 

 larvae.
