Report on injurious insects and plant diseases in 1902, W. M. Sciioykn

 J/). — As in otherannual reports by the author, attention is called to the more impor- 

 tiint insect outbreaks during the season. A large numl)er of injurious insects are men- 

 tioned, being classified according to the plants to which they were injurious. On 

 cereals the chief injuries observed were due to crane flies, grain aphis, and frit Hy. 

 Grasses were attacked by Cliarxas graminis and Cleigaslraj!aripr.'>. Clover was injured 

 to considerable extent by Sitonen lineatus. Notes are also given oji the pea weevil, 

 cabbage-root maggot, Hcdtiea nemorum, cabbage worms, tarnished plant bug, pear- 

 tree psylla, pear-leaf blister-mite, apple scab, black rot of apjiles, currant sawtly, 

 Bomhy.v pirn, RMzotrogus solslitialu, Lophyrus rufus, etc. 



Injurious insects, E. Fleutiaux {Jour. Agr. Prat. Fag.'i Chaud.'i, 2 {190.1), No. 10, 

 pj>. 495-502). — Brief notes are given on insects injurious to sugar cane in Java, and 

 on a weevil which attacks the banana in Madagascar. This weevil was determined 

 as Sphenophorug sordidus. A list is also given of injurious insects captured in 

 Guadaloupe. 



Recent experience with destructive insects, Maky E. Muktfeldt {Mhs^ouri 

 Slate Ilort. Soc. Rpt. 1902, jrp. 253-258). — Economic and biological notes on canker- 

 worm, tarnished plant bug, leaf hoppers, raspberry-cane borer, etc. 



A new enemy of cereals, F. Malmejac {Meun. Francaise, 18 {1902), Nos. 197, 

 pp. 6-8, figs. 19; 198, p. 33; 199, p. 56; 200, p. 79; 201, p. 105, 106; 202, pp. 125, 

 126). — The author describes a new species, under the name of Fentatoma triticum, 

 a bug which is said to have caused considerable damage to wheat. The insect is 

 described in consideraljle detail and elaborate notes are given on the character of the 

 damage caused by its attacks. It was found to attack chiefly the heads of wheat 

 and more rarely the leaves and other parts. Low temperatures are said to be unfa- 

 vorable to the species, and it can be destroyed by applications of kerosene enndsion. 

 The insect attacks wheat during the formation of the grain and even after the kernel 

 is dry. The effect of this attack is to increase the moisture and sugar content and to 

 diminish the proteid content. 



Hessian fly experiments, H. Garman {Kentucky Sta. Bid. 103, pp. 229-244).— 

 The purpose of these experiments was to determine the time at which wheat may be 

 planted so as to escape the Hessian fiy and avoid injury from freezing. Wheat 

 planted in the fall of 1901 in Kentucky produced rather a poor crop. This was 

 attributed by some to late planting, by others to the Hessian fly, but the author 

 believes it was due to bad weather at the time of planting. It appears that eggs laid 

 late in the season do not hatch. On some infested plats Avheat was i)lanted again in 

 the fall of 1902, beginning September 15. The earliest plantings were injured to the 

 extent of 37 per cent, while plats planted from October 13 to 27 were not infested." 

 According to the author's observations, wheat that escapes injury in the fall will be 

 injured in the spring in proportion to its nearness to fall infested wheat. 



Experiments were made in the use of air-slaked lime, lime and Paris green in 

 water, Bordeaux mixture, and kerosene emulsion. The following percentages of
