Haseman (L.). Chinch Bugs becoming dangerous.— Mmouyi Agric. 

 Expt. Sta., Columbia, Press Bull. 91, 13th May 1915. 



Hibernating adult chincli bugs {Blissus leucopterus) begin to lay eggs 

 in west-central Missouri in the early part of May. Those fields of wheat 

 which are badly infested should be used for pasture before 25th May 

 and then ploughed as deeply as possible to bury most of the eggs 

 and young. If a crop is to be planted, cowpeas or soybeans are the 

 best. Where there is a good crop of clover in the field, mowing the 

 wheat closely will be sufficient ; a ditch or log barrier can be used to 

 check migration. Wheat which will give a partial crop need not be 

 cut ; the bugs in such fields can be destroyed after harvest, if barriers 

 are properly used.

Rhynchites -pauxillus. Germ., occurs all over South and South- West 

 Russia, along the steppe lands of the Volga, as far as Kazan and in 

 Caucasia. In the government of Saratov, it appears at the end of 

 April, in the Crimea in the first half of March, in Ekaterinoslav in the 

 first half of April. The weevils feed at first both on flower and leaf 

 buds, and later on the leaves, on which they oviposit. Oviposition 

 takes place during the latter half of April and May, the eggs being 

 laid in a hole made by the proboscis of the females in the petioles of 

 the leaves. The larvae hatch in 6 or 7 days and enter the leaves, 

 feeding on the parenchyma. The infested leaves drop from the trees 

 in June and July. When mature, the larvae pass into the earth and 

 pupate, producing adults in September, which mostly pass the winter 

 in the earth, but in warm days in September and October they frequently 

 emerge and injure the buds of fmit trees. Mokrzecki, in the Crimea, 

 reared the parasites Bracon discoides, West., and Pteromalus sp. from 

 this pest, but the author foimd no parasites in the government of 

 Kiev in 1912, notwithstanding the large numbers in that year. He 

 recommends the following remedies :• — Spraying with milk of hme 

 before the appearance of the weevils ; spraying with the remedy of 

 Chubuktchi, which is prepared as follows : about 20 gallons of washed 

 clay are thoroughly mixed with about 30 gallons of water in a tub, 

 while in another tub lime is mixed with water to the thickness of 

 cream and about 20 gallons of this added to the clay and water ; to 

 each 15 to 25 gallons of this mixture 1 lb. of soap is added. Appliances 

 used for shaking the beetles from the trees are described and figured, 

 and digging the ground to destroy the larvae and pupae is advised. 



Rhynchites Bacchus, L., has the same distribution in Russia as the 

 last species, appearing everywhere before the buds burst. These 

 weevils injure with their proboscis the fruit and flower buds of apples, 

 pears, cherries, apricots, plums and sloes, the injuries being more 

 serious than those caused by R. pauxillus. These injuries were first
