Scales of the genus Lecaniiun have no armor or hardened 

 covering, and are known as unarmored or soft scales. 

 They are very susceptible to the contact of poisons like 

 kerosene emulsion and whale oil soap, and are therefore 

 easy to kill. 



One of the most important things to which I wish to 

 call your attention is the bringing into the State of two 

 species greatly resembling San Jose Scale and, from what 

 we know, are about as bad. They were brought into Con- 

 necticut on nursery stock and, as I understand the matter, 

 both came under certificates of inspection. One of these, 

 Aspidiotus forbesi John., was found in Illinois in 1894, and 

 described in 1896 by Professor W. G. Johnson, now of the 

 Maryland Experiment Station. Professor Johnson found 

 cherry trees badly infested and considered this the most 

 dangerous scale then established in Illinois. He reported 

 that the scale occurs upon the wild and cultivated cherry, 

 apple, pear, plum, quince and currant. He proposed the 

 popular name of "Cherry Scale" for this insect. It was 

 shipped into Connecticut on apple trees from Pennsylvania. 

 The second species is Aspidiotus ostreceformis Curtis, 

 which was introduced into this country some time ago from 

 Europe, but was not discovered imtil during the past sea- 

 son. It closely resembles the San Jose Scale, and has 

 often passed for that species. It has become well estab- 

 lished in Central New York and has been reported from 

 Michigan and Canada. It was brought into Connecticut 

 from New York on pear trees. 



Though we cannot predict regarding the serious nature 

 of these species in the Eastern States, it is quite probable 

 that either may prove just as undesirable a pest as the San 

 Jose Scale, and it is for the interest of ever)-- fruit grower 

 to make frequent and careful examinations of all trees 

 obtained from nurseries, whether accompanied by certifi- 

 cate or not. and of the trees growing in his orchards. Any 

 new or suspicious specimens should be referred to your 

 committee, who are prepared to have them accurately 

 determined and to advise treatment. 



No laws exist in Connecticut at the present time 

 regarding the transportation of infested plants or trees.
