Book Description
Excerpt from Experiments in Controlling Corn Ear Pests in Puerto Rico Ears were harvested and examined at roasting-ear stage of develop ment. All ears were harvested at the roasting-ear stage and immediately examined for extent Of filling of the ear as well as for the presence of insect larvae. Separate records were taken for each ear, the presence or absence of both species Of earworms or the small, corn-silk fly larvae being recorded. It is difficult to distinguish the larvae of the corn earworm from those Of the fall armyworm; since both are known to be present in the island and since they caused the same kind Of damage no attempt was made to separate them, and both types are mentioned together. The presence Of a single larva Of any one of the three ear pests was sufficient for an ear to be classified as infested. Protecting silks for period prior to pollination resulted in poorly filled. Ears. The filling of the ears was unsatisfactory even when the silks were exposed for 168 hours. Only 10. 4 percent Of the ears were well filled following the 4-hour exposure, 53 percent as a result Of the 24-hour exposure, and only 61 percent after 168 hours' exposure. A summary of the results Of the insect infestation counts are shown by treatments in table 1. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
