The Clover Leaf Weevil. — Weekly Press Bull, Penns. Depi. Agric, 

 Harrisburg, i, no. 19, 18th May 1916. 



The clover leaf weevil [Hypera variabilis] has recently occurred in 

 injurious numbers in the eastern part of Pennsylvania. There is no 

 known method of controlHng this pest, but it can be checked to a great 

 extent by pasturing. Ploughing under red clover after the second 

 season, materially reduces the numbers. Mowing the clover has a 

 certain disadvantage, in that the weevils may survive on fallen leaves, 

 etc., until the new growth has appeared.

The author made experiments in the summer of 1915 at Irkutsk on 

 spraying plants of Calendula officinalis attacked by caterpillars of 

 Barathra [Mamestra) brassicae with solutions of extract of Aloe and of 

 Veratnmi album. Although the plants were in full bloom, they were 

 not damaged and afterwards gave a good crop of seed, though the 

 insects were killed by the insecticide. This experiment confirms a 

 similar experiment with tobacco by Glasenapp [see this Revieiv, A, i, 

 p. 370].

The author gives a short account of the life-history of the Pyralid, 

 Zophodia convolutella, Hb., and its control. The adults are on the wing 

 in spring and oviposit on the berries of currants and gooseberries ; 

 the larvae penetrate into the fruits and feed on their seeds and contents, 

 passing from one fruit to another. The larvae pupate in the soil and 

 winter as pupae, the imago emerging in the following spring. The best 

 remedies consist of the removal of injured berries and collecting the 

 caterpillars, digging the soil in autumn and winter, and spraying in 

 spring with a mixture of Bordeaux liquid (Jib. of copper sulphate, 

 J lb. of quick lime in about 3 gallons of water) and Paris green (| oz. of 

 green and 1| oz. of quick lime in about 3 gallons of water) which 

 prevents oviposition and poisons the larvae. Bushes exposed to the 

 sun are avoided by the females and measures which improve ventilation 

 are therefore advantageous.

The insect pests recorded during the summer of 1915 include : — 

 Gryllotalpa gryllotalpa, L., (vulgaris), which injured plants in market- 

 gardens, especially early tomatoes ; Thrips (abaci, Lind. (communis, 

 Uzel), which was specially injurious in the first half of July ; Tingis
