Grape Galls. 



Bladder-like galls on gi'ape are occasionally noted eacli season, 

 and in some years they are quite generally distributed and attract 

 a great deal of attention. During the past season the trouble seems 

 to have been quite generally distributed and reports have come 

 from a number of localities, but chiefly the more northern sections 

 of the State. The trouble is due to a, small midge, Lasioptera, vitis, 

 which lays its eggs in the tissue of the leaves, leaf stalks or even 

 the tendrils. When the eg^ hatches into a minute larva the plant 

 tissue swells and forms a small or large swollen mass which, when 

 cut, is a sappy, cellular tissue with a central cavity for the lai*va. 

 A badly-infested vine presents a curious appearance in late May or 

 early June, and after a few days little round holes ap}>ear in the 

 swollen masses. This indicates that the insects have reached 

 maturity and very soon thereafter the swellings disappear leaving 

 no trace, and without j^ermanent harm to the vine. 



Rose Chafer. 



This species has continued to increase and was more widely in- 

 jurious tJian during the summer of 1905. At Vineland grapes 

 suffered severely, but the insects were very unevenly distributed, 

 and in some vineyards practically none at all were observed. Other 

 fruits suffered to some extent, but no notable damage was caused. 

 In this place, while they were more abundant than they have been 

 for years, they are not yet as abundant as they were in 1890. At 

 Oceanic they were also injurious to grape and attacked other fruits 

 as well. The flowers of the tulip tree are always very attractive 

 to the beetles, and on a poultiy farm, where such a tree was in a 

 lot used as a chicken run, the owner shook down a mass of the 

 beetles which were promptly sna,pped up by the chickens. As a 

 result twenty of them were dead next morning, and on cutting 

 open the crops these were found packed in a solid mass with the 

 insects. Ordinarily chickens do not touch the beetles at all, and 

 whenever they do the result is apt tO' be bad, but ducks seem to 

 manage the insects all right. 



At Matawan strawberries were attacked and both foliage and 

 fruit were eaten. At Elm, tliey were general in their feeding and
