HOW TO DESTROY INSECTS. 73 



feerosene-ou this, sprinkled on the vines when the 

 dew is on, will generally answer for the season. If the 

 bugs return repeat the operation. 



" I applied it this season on several thousand hills 

 ot melons, cucumbers, etc., after the bugs had com- 

 menced operations, and have not since had a vine de- 

 stroyed. I have used it for several seasons with the 

 same result. This is safer and cheaper than Paris 

 green." 



May -bugs. 



A successful experiment was tried in Germany for 

 destroying May-bugs on a large scale. 



It is known that these bugs always select warm and 

 loose ground for the depositing of their eggs. 



Consequently seventeen artificial breeding places 

 were prepared by covering fresh cow-dung with fine 

 earth, and by the middle of July they were found full 

 of eggs or grubs. 



After collecting these eggs, etc., they were burnt 

 outside the forest. 



Aster -bugs. 



Plaster sprinkled over the plants while wet with the 

 dew will put them to flight. It is also an efficacious 

 remedy for the rose -slug. 



Quassia-tea will also keep bugs from eating aster 

 flowers.
