 leucostigma, S. and A. — 16(k Rept. State Entomologist of Connecticut

An account of this pest has already appeared [see this Review, 

 Ser. A, V, p. 174], but the following facts may be added. In 1908 it 

 caused serious damage in apple orchards and in 1916 it was reported 

 as feeding on peach and quince trees, though it usually attacks poplar, 

 elm, horse-chestnut, linden, soft maple and other shade trees. In 

 addition to the Hymenopterous parasites mentioned in the former 

 account, Dr. Howard records the following : — Pimpla inquisitor, Say, 

 Chalcis ovata, Say, Scmnbus marginatus, Prov., Pimpla annulipes, Say, 

 Meteorxs communis, Cress., M. hyphanlriae, Riley, Limnerium 

 validum. Cress., Theronia fulvescens, BrulL, Apanteles delicatus, How., 

 A. hyphanlriae, Riley, and A. parorgyiae, Fitch. Several Dipterous 

 parasites have been reared from the cocoons, including : — Frontina 

 alefiae, Riley, F. frenchi, Will., Tachina mella, Walk., T. clisiocampae, 

 Towns., Euphorocera claripennis, Mcq., Exorista griseomicans, Wulp, 

 Winf hernia quadripustulata, F., and Sisyropa sp.

Much of the matter contamed in this paper has already been dealt 

 wuth [see this Review, Ser. A, iv, p. 392, and Ser. B, iv, p. 26]. It 

 has been found that the destructiveness of the rose chafer over wide 

 geographical areas varies with the nature of the soil, being greatest 

 in sandy regions, where the insect breeds, and least where the soil is 

 a heavy clay. The grape-vine is particularly Uable to attack, the 

 blossoms and newly-set fruit being destroyed. As the insect is 

 attracted by white or light-coloured flowers, the presence of these 

 near vineyards should be guarded against. The newly-set clusters of 

 grapes may be protected by enclosing them in a paper or cloth bag 

 w'hich is pinned tightly round the stem, a method which gives good 

 results in the garden, but is hardly practicable in vineyards. As 

 regards control by cultivation, it has been found that the larvae and 

 adults are very hard to kill, while the pupae are easily destroyed. 

 Hence ploughing and harrowing the ground, or deep cultivation 

 during the last week in May, when the insect is in the pupal stage, is 

 likely to prove efficacious. 



Britton (W. E.) & Lowry (Q. S.). Experiments in controlling the 

 Striped Cucumber Beetle and the Squash Borer. — 16th Rept. State 

 Entomologist of Connecticut for the Year 1916, Conn. Agric. Expt.

 17th May 1917.] 



Field experiments in the control of certain insects attacking 

 Cucurbitaceous plants have been undertaken but so far have only 

 indicated possible lines of treatment, no satisfactory results having 

 been obtained. The striped cucumber beetle, Diabrotica vittata, F.,
