hand picking is therefore advisable on small trees. Normally this 

 beetle breeds in oak, beech and hickory twigs, and possibly visited 

 the pear trees from the neighboring woodland. It has also been 

 known to attack peach. 



Snout Beetle Injuring Greenhouse^ Plants. On April 6th, 

 beetles were received from Litchfield, where they had been eating 

 the leaves of palms, lemon tree, Tradescantia and Draceena. It 

 proved to be Otiorhyncus sulcatus Fabr. 



Strawberry Weevil. On June 3d specimens of the strawberry 

 weevil, Anthonomus signatus Say were received from South 

 Killingly and from Huntington, where at both places the stems of 

 the buds and developing fruit had been eaten by the weevils. This 

 insect is a snout beetle of the family Curculionidcs, and is less 

 than one-eighth of an inch long and brown or black, with white 

 markings. 



The injury is caused by the female, which lays an egg in the 

 bud just before it opens', then crawls down the pedicel and cuts 

 it partly ofl, so that it fails to develop and later becomes separated 

 and falls to the ground. The growing larva feeds upon the pollen 

 inside of the bud, which after falling to the grotmd is kept moist 

 and in a condition favorable to the development of the larvae, 

 which reach their full size in about three or four weeks. 



The strawberry weevil when abundant is a difficult pest to 

 control, and arsenical sprays are not very satisfactory. Pistillate 

 varieties are not attacked, and growers are advised to grow only 

 enough staminate plants for purposes of fertilization. Clean 

 culture is also to be recommended. 



Raspberry Sawfly. The raspberry sawfly, Monophadnoides 

 rubi Harris, was present in a number of berry patches around 

 New Haven, and was sent in from Stonington on July 8th. 

 The larvae are nearly three-quarters of an inch long when fully 

 grown, dark green in color, and covered with Ughter green forked 

 spines. They devour the leaves of raspberry and blackberry, 

 usually being found upon the upper surface. The eggs are white 

 and are laid in the tissues of the leaf. The adult is a four-winged 

 fly with a black thorax and dark reddish abdomen. Spraying with 

 arsenites, or even with fresh hellebore, may be practiced as a 

 remedy.
