turner: kernel spot on pecan 
445 
After it had been proven that kernel spot was purely a physiological 
breakdown following the feeding of a bug, it seemed quite possible that 
other species might have the same effect. With this point in view six 
adults of a species of Euschistus were confined in two cages and eleven 
adults of Leptoglossus phyllopus F. were confined in three cages. The 
results are given in table No. 2.

The spots caused by these two species appeared to be exactly like those 
following the attack of N. viridula, and these results simply confirm the 
conclusions already reached, as to the nature of the trouble. From 
the practical standpoint the interest of the grower should still be con¬ 
fined to the Green Soldier Bug, since that is the only species which has 
been found in sufficient numbers to cause any economic injury. 
One thing has impressed the writer most strongly duiing the study of 
this trouble, and more particularly in the study of the literature con¬ 
cerning the Southern Green Soldier Bug. This is the lack of careful 
study directed toward an understanding of, not only this species, but 
of the Heteroptera in general. There seems to be no doubt that such 
study will solve many of our present problems as well as many of those 
of the plant pathologist. The field is practically a virgin one and I 
believe offers the best opportunity to the beginner in Entomology today.
