 iinattractixc to the moths as ((impaicd with the vigorous ('arly 

 plants. 'I"he smmnei' vaiielies mav \n- taken onl and destroyed, 

 with all theii' ((intents ol horer-^, alter an eaily ( lop has been 

 picked liom them, and this will leave the later varieties free, 

 while it also acc(jmplishes the deslrnelion ol an entiic brood oi' 

 larva. So it lias been found |)ra( tieable in the .South to proU-ct 

 cabbages from the attacks ol the h.ule(|nin cabbage bni;' by 

 planting' au early lra]j crop ol luuslaid, to which the insects are 

 attracted, and Ironi vvhii h they (an be gathered by hand or 

 destroyed by s])rayin!L; with jau'e kerosene. 



An instance ol the use of methods ol cultivation we fmd in the 

 practice of blackberry ij^rowers, who, to |)revent injury from the 

 red necked cane-borer, cut oil during the latter part of )une all 

 the shoots tluMi above ^r'lnnd, and either jj;^atlier and destroy, or 

 merely allow them to wilt and die. The beetles have all disap- 

 peared at this time and all their e^j^s ai^e in these shoots. The 

 new canes that come up alter this tiimmini; bi-come sulliciently 

 mature and aie in sulhcient number to make next year's crop 

 while they are free from any pcjssible beetle attack. 



There are many other ways in which farm practice may jirevent 

 injury from insects, and to the intellit.;('nt larmer tlurse methods 

 will commend themselvc;s much more than the indiscrimin.ite use 

 of ins(/cticides after damage has been caused. The |)revention of 

 attack is always better than the destruction ol the insects alter 

 injury has been acc(miplished, and some oi these mc^thods have 

 the advantajLii'e of effectin^'a ])ermanent reduction of the injurious 

 species. I""urllier details are hardly in place here, but what has 

 been said will e.x])lain the reason lor many of the recommenda- 

 tions made in the body of the work.
