lated witli fmig'us diseases, and sent back fin^ distribution in the fields, 

 A combined and concerted campaign is advocated and emphasized. 



Report of the entomologist, 11. A. Morgan {Louisiana Stas. Bui. 

 ^8, M scr., pp. !)S2-1005, figs. 6'.)— Tliis deals witli the treatment for bit- 

 ing- and sucking insects, the arsenites being advised for the former and 

 kerosene and rosin emulsions for the latter, receipts for compounding 

 the insecticides being included. Fishoil emulsion is recommended for 

 flies and gnats. 



Kotes are given on the following species, and iniuost cases descrij)- 

 tions, hie histories, and treatment. The sugar cane borer [Ghilo sac- 

 ckaralis), screw worm tly {Lucilia macellaria), Angoumois moth [Gelecliia 

 ccrcalella), corn weevil {Galandra oryzae), purple scale {^lytilasjyis citri- 

 cola), Glover scale (M. gloverii), red scale {Aspidiotus ficus), walnut 

 scale {A. juglans-regi(c), roimd white scale {A. nerii), greedy scale (A. 

 rapa.v), chaff scale [Parlatoria pergandii).! white fly {Aleyrodes citri), 

 Cameliajaponica scale {Fiorinia fioriniw war. camellice), rose scale {Dis- 

 s/s rosfc), sweet potato borer {Gylas formicarius), chinch bug {Bliss us 

 leucopterus), peach borer {Sdnnina exitiosa), fig borer, and cattle tick 

 {Boojyhilus horis). 



Observations on farm pests, H. Gae3ian {KentucJcy Hta. Rpt. 

 1S90, pp. !)-4(), figs. 7). — Original and compiled notes on various insects, 

 descriptions, life histories, and treatment being given. The corn-root 

 worm of Kentucky {Diabrotica 12-punctata)., grain hnise {Slplionopliora 

 avence), tobacco worm {Phlegethontius Carolina), strawberry scale insect 

 {Aleurodes vaporarium f), and niyriapods {Camhala annulata and Para- 

 julus impressum) are discussed. Descriptions are given of 3 parasitic 

 Hymenoptera, Apanteles coiigregatus, ^J^tro.rys tabacum, and 3feso- 

 chorus sp., infecting the tobacco worm, and a wheat spring tail {Smyn- 

 thurus sp.) which devours parasitic fungi on young wheat in the spring 

 is also described and figured. 



Rotation of crops is advised in the case of the corn-root worm, and 

 against the grain louse a strong extract of tobacco stems or weak ker- 

 osene emulsion is suggested, and also the planting of trap strips of 

 oats to attract the lice, which can be plowed under when infested. 

 Hand picking, and planting Jamestown weed, the flowers of which are 

 to be poisoned with cobalt, arsenic, or strychnine, are recommended 

 against the tobacco worm. An infusion of tobacco or a solution of 

 naphthaline was fonnd to kill niyriapods quickly. 



Bordeaux mixture as an insecticide, H. Gakman {Kentucly Sta. 

 Rpt. 1890, pp. 40-43). — On account of the elfect produced in deterring 

 the attacks of cucumber flea beetles and margined blister beetles on 

 potatoes by spraying with Bordeaux mixture, experiments were made 

 to ascertain its value as an insecticide. Tobacco worms, grasshop- 

 pers, and Colorado potato beetles were confined in breeding cages and 

 supplied with sprayed food plants. All of the tobacco worms and 

 grasshoppers succumbed, while individuals kept as checks remained 

 vigorous. The potato beetles, however, were but slightly affected,
