REPORT OF THE STATE ENTOMOLOGIST IQOO IOO9 



hoppers are more numerous than they have been for years. They move 

 in swarms and soon eat up a piece of corn or oats. Aug. i8. Morning- 

 glory leaves are badly mined by [Bedellia somnulentella Zell.] 

 [This insect was also observed to be present in large numbers at Floral 

 Park about the same time.] Oct. 2. 



Genesee county (J. F. Rose, South Byron) — Appletree tent-cat- 

 erpillars [Clisiocampa americana] appeared in unusual numbers 

 last week. The season is backward, and no leaves show on the apple- 

 trees and the buds are but little swollen. The caterpillars are feeding on 

 the blossom buds of those varieties which are considerably advanced. 

 The lines of silk lead from the nests to the fruit spurs. The nests are 

 very numerous on the wild cherry, and on these no leaves have appeared. 

 May I. I am miable either by observation or by inquiry of prominent 

 fruit growers to learn that the cold did any injury to the young cater- 

 pillars. Ice ^ of an inch thick formed here, and there were hard frosts 

 for several nights. May 11. Tent-caterpillars are very bad in many 

 orchards. Spraying is neglected by many till the caterpillars 

 have attained considerable size, and then they have poor success 

 in killing them with paris green. When the poison has been used 

 at the rate of i pound to 100 gallons or stronger, the results have 

 been better. Many of the caterpillars are now full-grown and 

 have begun to travel, preparatory to spinning their cocoons. Can- 

 kerworms have been working so badly in some orchards that spraying 

 while the trees were in full bloom has been done. Eye-spotted bud 

 moths [Tmetocera ocellana] have greatly increased, and many 

 are found on pears and quinces. Potato beetles [Doryphora 10- 

 1 i n e a t a] were found in numbers today, though they had been scarce 

 previously. May 26. The early potato and tomato leaves look like 

 sieves, as the result of the work of the cucumber flea beetle [Crepi- 

 dodera cucumeris] The striped cucumber beetle [D i a b r o t i c a 

 vittata] is present in usual numbers. Tent-caterpillars are far more 

 numerous than ever before and are now crawling everywhere. The 

 forest tent-caterpillar [Clisiocampa d i s s t r i a] is not as bad as last 

 year. The pear psylla [Psylla pyricola] has been very trouble- 

 some and difficult to control. June 12. I was called to see an orchard 

 which is in a very serious condition from the attacks of an insect [palmer 

 worm. Ypsolophus pometellus]. June 14. The crop in this 

 orchard of 300 trees is a complete failure, though there was a full bloom. 

 It was sprayed with paris green only, the first time when the fruit was as 

 big as peas and then last week. Tent-caterpillars were also rather
