Excerpt from Experiments With the Muscardine Disease of the Chinch-Bug, and With the Trap and Barrier Method for the Destruction of That Insect To judge intelligently of the effect of any attempt to introduce disease, the observer should examine very carefully, in advance, the field in which the experiment is to be tried, and adjacent fields as well, to see whether bugs dead with the white fungus may not already be present. If the disease appears at the point where the infected chinch-bugs are placed, he should repeat this general examination, and make sure that the disease may not have occurred spontaneously and without special refer ence to his experimental introduction of it. He should also notice whether young bugs (those without wings) are attacked by it, as, if they are not, it is quite likely it is only carrying away those about to die of old age. On the other hand, it should be remembered that these especially susceptible adult bugs may afford the best means of securing a general dissemination of the fungus in the fields, where it may lie dormant for a considerable time, ready to spring into sudden activity when favorable weather conditions appear.
