ENTOMOLOGICAL NOTES FOR THE YEAR IN MARYLAND. 

 By T. B. Symoxs. Cnllegepark-, Mil. 



The past year has not lu'cn marked l)y any unusnal onlhicaks of 

 injui-ious insects, except in the ease of a few species, whicli will he 

 cited bi-iefly. The nsnal depredations b}' the San Jose scale have 

 occnii('(l, and wliich, il may he said, is bein<r conti-olled in a marked 

 dej;ree in many sections of the State ])y the nse of the lime, snlphni-, 

 antl salt wash. 



Many complaints were received in tlie sprint; from the damage done 

 to api)le foliaii'e by the "ai)ple aphis" [Apliis si)p. ), a)id it was neces- 

 saiy to i-eeommend several washes for their control. "Rose Leaf," 

 one part to forty parts of water; 15 per cent kerosene emnlsion, and 

 whale-oil soap, one i)onn<l to the <ranon of water, were the washes 

 snggested. 



The strawberr}' weevil {Anthonomus signatus Say) likewise did 

 considerable damage to strawberries in the State. This injnj-y was 

 especially severe this yeai' from the fact that a hirge nnmber of tlie 

 early blooms were killed by frost, which left a smaller percentage for 

 the needs of the weevil, redncing the crop in some instances one- 

 fonrth of tin' average one. 



Pearly in May and, in fact, thronghout the snmmer months the 

 ravages of the fi-nit-tree bark-beetle {Scolyius rugulosu.s Katz.) were 

 apparent in many orchards in the State. May 13, at St. Margarets, 

 we o])served several hundred trees injured by the beetle. My atten- 

 tion was called to many instances where the beetles had attacked 

 perfectly liealthy trees of peach, plum, and cherry. While this insect 

 commences its work on sickly or half-dead trees, there is no doubt 

 but that the beetles have developed the habit of attacking perfectly 

 healthy ones. There seem to be no better remedies than to destroy 

 the infeste*! trees and the preventive measures of k<M>ping <lea«l wood 

 cut out of tlu' orchard and carefnlly l)nrning all tlu' bi'usli. 



The apple-tree tent caterpillar {Clisiocamjxi [Maldcosoma] anieri- 

 cruKi) was present in nnnsually large numbers during the early 

 spring, but was practically controlled by bnrning and by the u.se of 

 arsenical i)oisons, together witli the unfavorable weather conditions. 



There was locally a serious outlneak of th(» corn .stalk-b()rer (Di'u- 

 tr(f(t saccJi(ir(ill.s), which attacked a fudd of corn in Kent County, 

 damaging about '25 per cent of the cornstalks. This in.scci has not 

 appeared in in.juiious numl)ers in Marylan<l since 1S!»S, and it is 

 peculiar to note its presence in sucli great nnmbers in two oi- three 

 coi-nfndds this year. Its injury consists in boring into the stalks of 



coi'U, thei-eby weakening tlu'in. and win-re several nr on a stalk !♦
