INSECT HAPPENINGS IN NEW JERSEY IN 1906, 37 



The catalpa 8])hiiix {Ceratoiii'uL catidpa' Bdv.) now covers about the 

 entire State of New Jersey, positive records being absent from one 

 county only. It always seems to be worse the second year of its 

 a])])earance in a given locality, and it has been about as troublesome 

 in nurseries as anywhere. 



Another failure to establish the Chinese mantid {Parntenodera 

 sinen.sis Sauss.) in New Jersey is to be recorded. A large number of 

 egg masses were tied out in an ideal location on the southeastern slope 

 of the Orange Mountains, and most of these fell a prey to field mice. 

 It seems curious that the insects should do so well near Philadelphia 

 and that they should fail so uniformly in all sections of New Jersey. 



The Asiatic ladybird {Chilocorus siniUis Rossi) has not been found 

 again, although the orchard in which the lots sent up from Georgia 

 three years ago were freed still stands unsprayed — what is left of it. 



Although not strictly entomological, mite infestation should be 

 noted as among the most important happenings of the season. Trees 

 and shrubs of the most diverse kinds were infested and a great deal 

 of foliage was disfigured, if not seriously injured,

Present indications are that the finiit growers of jSIaryland may 

 have another serious scale pest to contend with in the near future. 

 We refer to the tei-rapin scale {Ei/lce((iiii/m uif/rofdsctatiim Per- 

 gande). From different localities in AVashington County have come 

 three complaints of very serious injury to peach trees by this scale. 

 All told, several hundred trees have been killed or l)adly damaged 

 by it. The growers report that the lime-sulphur-salt treatment is 

 not effective against this pest, it being no uncommon thing to see 

 full-grown scales in midsunnner with a coating of the spray mixture 

 still adhering to their backs, but apparently none the worse for it. 



A more or less careful study of the life history of the insect was 

 made at the Station the past season, and it brought out the following 

 facts: The scales pass the wintei* as immature females, finishing their 

 growth in the spring. The eggs are deposited beneath the female 

 scale, and are very numerous. Hatching begins about June 1 in our 

 latitude, and crawling young nujy be found from that time initil the 

 second week in August. The young api)arently all go to the leaves 

 iuunediately after hatching, and there settle along the midi'ibs and 

 veins, where they remain for a period of from six to eight weeks. 

 The males then emerge, winged, while the females migrate back to 

 the twigs, settling along the under side of the twigs and branches. 

 This migraticm of the females began al)out July 20, and l)y September
