THIRTEENTH ANNUAL MEETING. ly 



infested localities have been discovered during the year. Some- 

 thing like 40.000 trees in Connecticut have been sprayed with 

 the lime and sulphur mixtures during the past season. The 

 results were generally satisfactory. To go into details here 

 regarding the treatment against this insect Avould be to antici- 

 pate the subject which our Secretary has given a place on the 

 program of this meeting. 



It has not as yet been possible to obtain from the authorities 

 at Washington any of the Chinese lady-beetles for Connecticut, 

 though the application was made more than two years ago and 

 has been several times renewed. 



The tent caterpillar, Clisiocainpa americana Harr., was abun- 

 dant throughout the northern and central portions of the State, 

 in some sections the nests being extremely common. Many of 

 the caterpillars died, however, before reaching maturity, accord- 

 ing to reports received by your Committee too late to examine 

 material to ascertain the cause of death, though the circum- 

 stances indicated the presence of the bacterial disease which is 

 known to attack the caterpillars. 



The injuries from the codling moth, Carpocapsa pomonclla 

 Linn., were about what we expect each year, and the apple 

 maggot, Rhagolctis pomoncUa Walsh., was very destructive in 

 some sections of the State. This latter insect is a difficult one 

 to control as it is out of the reach of sprays and we must rely 

 upon the choice varieties and the destruction of infested fruit. 

 The codling moth can be controlled by spraying with the 

 arsenites. 



The seventeen-year locust or periodical cicada was expected 

 to make its appearance in Connecticut during the season, but I 

 have been unable to obtain a single record of its occurrence, 

 though it has been reported from Rhode Island. 



Two new beneficial insects have been brought into the State, 

 which we hope may prove of considerable value, as they feed 

 upon other insects, chiefly injurious ones. Both belong to the 

 order Orthoptera, and the family Mantidce. The European 

 Praying 3ilantis, Montis rcligiosa Linn., is about 2)^ inches 

 long, green or brown in color, and has become firmly estab- 

 lished in the vicinity of Rochester, N. Y. It was, ]:)robably, 

 introduced from Europe in shipments of nursery stock. The 

 Chinese Mantis, Tenodera sinensis Saus., has evidently been 

 accidentally introduced into Connecticut, as egg-masses were
