INJURIOUS INSECTS.

Chinch Bugs (Blissus leucopteris.) — The chinch bug does 

 it trouble any of our, garden products except corn, but is some- 



Remedies. — The burning of rubbish accumulations along 

 headlands, fences, etc., in the winter or early spring in infested 

 localities will destroy many. They always infest the small 

 grains before they do corn. 



While these insects have wings they use them but little in 

 their migration in summer, but they travel on foot and often m 

 great numbers. Taking advantage of these peculiarities they 

 may be kept from corn fields by plowing deep furrows in their 

 way*, which should be turned back as soon as filled with bugs 

 and new furrows made. Fences of boards six inches high with 

 the upper edge kept covered with tar will keep them out, but 

 holes in the ground should be made at intervals along the line 

 of the boards, which when full of bugs should t)e filled in with 

 earth, and new holes made. A dusty headland or road is very 

 difficult for them to go through. If they finally reach the corn 

 they will readily succumb to kerosene emulsion. Much is being 

 done to rid the grain fields of this pest by infecting the bugs 

 with disease. This works most rapidly in moist weather, but 

 other remedies should not be put aside for this one. 



Bean and Pea Weevil (Bruchus sp.) — The insects known 

 as weevil are quite common in some sections. They work in 

 the seed of beans and peas. The adult insects are small beetles 

 which lay their eggs in the flowers where they soon hatch and 



I 



times very injurious to this vegetable and 

 may kill it in a very few days if neglected. 

 This is a sucking insect that winters over 

 in the adult state under leaves and in dry pro- 

 tected places generally. When full grown 

 it is about one-seventh of an inch long with 

 Vv^hite upper wings which have two well de- 

 fined black spots on them. When crushed 

 they have an offensive bed-bug-like odor, 

 This insect is not affected tiy cold weather, 

 but succumbs quickly to moisture. The fe- 

 male deposits her eggs near the ground upon 

 the stem or roots of wheat, oats, grasses, etc.
