Expression of damage to sweet corn by the Japanese beetle (Popillia japonica Newin.) depends on the amount of uninterrupted time available for the pollen to fertilize the ear completely. In Tendermost sweet corn the minimum time is about 8 hours, as compared with 7 hours for field corn. In years of heavy beetle infestation one treatment during silking will suffice if followed by recommended measures for control of the corn ear worm (Heliothis zea (Boddie)). Light to moderate beetle infestations have no effect on marketable quality of sweet corn. |
