354 ANNUAL. REPORT OF THE Off. Doc. 



upon the skin ot i-cn-soiis passing beneath the trees and cause serious 

 irritation and rash, actually keeping people indoors and off the 

 streets at times when the hairs are falling. At the close of this 

 address I shall show some slides illustrating a few features of this 

 important pest. 



Our farmers and fruit growers should become familiar with such 

 pests in order to watch for them and co-operate with the State De- 

 partment of Agriculture in preventing their importation or start 

 in this State. We are now in touch with the importers of nursery- 

 stock and doing all that is possible to inspect such stock at the time 

 it is unpacked, and thus prevent the introduction of this and similar 

 pests. Your Entomologist is to go next Tuesday to New York to 

 attend a conference of Eastern State Entomologists regarding this 

 pest. 



3. The Codling Moth is one of the arch enemies of the fruit 

 grower, but has been well suppressed this year by spraying with 

 Arsenate of Lead, 2 lbs. in 50 gallons of Bordeaux Mixture, made with 

 three pounds of Copper Sulphate and four pounds of Lime. This, 

 however, has this season caused unusual russetting of the fruit, and 

 we therefore recommend, for the first spray (just after the blossoms 

 fall) reducing the copper sulphate to two lbs. instead of three. One 

 of the chief features of the Codling Moth spray has been the use 

 of Arsenate of Lead in preference to Paris Green. One reason for 

 this is that the former sticks so much more readily to the fruit and 

 there is not so much danger of burning either fruit or leaves. 



4. The Ango'umois Grain Moth. This pest has proven very de- 

 structive in wheat in the southeastern portion of the State. We 

 have had many complaints of injury to wheat; and several samples 

 of grain damaged by it were received. This insect in the adult stage 

 is a winged moth which, in color, size, and manner of flight resembles 

 the little clothes moths which are frequently seen in houses. Sam- 

 ples are herewith exhibited. 



There are at least four broods per year. The moth of the first 

 brood flies and lays its eggs about the time the wheat comes into 

 head. The second brood appears just after the grain is mature. 

 The third, during warm seasons, comes about the middle of Septem- 

 ber, while the fourth brood appears in grain stored in barns about 

 the middle of October. It passes the winter in barns and granaries, 

 particularly in bins where the grain is stored. Tlie eggs are laid 

 beneath scales of chaff in the grooves of the grain. The damage is 

 done by the larva which feeds within the grain, rendering it nothing 

 but chaff, and, of course, quite worthless for milling purposes. Evi- 

 dence of the pest is to be detected by breaking open the grain, but 

 when there is much infestation, if is <^etected by the heating of the 

 grain in the bin. due to the gnawing of the larvfP. 



When the grain is left in the straw, or unthreshed, the moths have 

 opportunity to scatter among the heads and lay their eggs very ex- 

 tensively, but when it is threshed early, and the grain stored in bins, 

 the moths can only lay in the top layer of grain, and thus are not 

 mearly so destructive. After complete growth within the grain, in 

 about twenty to twenty-four days, the larva transforms into a pupa 

 or chrysalis, which is likewise within the grain, where it finds pro- 

 tection.
