REPORT OF THE STATE ENTOMOLOGIST 1918 By, 
insects begin feeding, it is evident that quince growers should watch 
closely for the first feeding punctures and be governed accordingly 
unless they prefer to make three applications, one just after blooming, 
a second about 2 weeks later and the third the latter part of July, or 
in other words, give practically the same treatment as the usual three 
sprays advised for the control of the codling moth. Usually the 
first would be too early to secure the best results and the second 
might well be delayed a little longer; otherwise it may be washed off 
before the insects feed to any extent. The ideal is to give the first 
treatment just after the curculios issue, making a second application 
- a week later. 
Magdalis barbicornis Latr. A few specimens of this insect were 
received July 9, 1917, together with samples of their work on quince 
from L. F. Strickland, Lockport, N. Y. The first sending was sup- 
plemented by a considerable series of beetles and samples of their 
work, July 12, 1918. This small, black weevil is a European species 
which has been recorded from Staten Island, N. Y., and Dorchester, 
Mass., feeding on elm in the latter locality. 
The weevil gnaws irregular skeletonized areas on quince, the 
eating being on the underside of the leaf and consisting of excavations 
of the more tender tissues between the veinlets. The affected areas 
soon turn brown, are irregular and may vary from small spots with 
a diameter of approximately a twenty-fifth of an inch to diverse 
shaped areas, with a major diameter of one-half of an inch to an inch. 
Mr Strickland states that out of a total of 464 leaves examined, 156 
exhibited injury of this character. The writer has noted similar 
work in earlier years upon quince trees in different parts of the State 
and there is a fair probability at least of the damage being caused 
largely if not entirely by this introduced insect. 
Thorough spraying the last of June or early July with arsenate of 
lead would very probably protect the foliage if it did not destroy 
the weevils. 
Raspberry Byturus (Byturus unicolor Say). Injuries by 
this pest in Milton and Marlboro continued the present season and 
in the judgment of one grower some 25 per cent of the crop is fre- 
quently lost through the work of this insect, although many growers 
attribute the shrinkage to something else or accept it as one of the 
inevitable developments. 
The most satisfactory method of controlling this species is by early 
and heavy applications of arsenate of lead, using 8 pounds of paste 
to roo gallons of water and spraying before the beetles have inflicted 
material injury. The beetles feed upon the unfolding leaves or
