Abstract
On May 4, 1959, the harlequin bug, Murgantia histrionica (Hahn), appeared in large numbers in a restricted locality in southern Minnesota. Fourteen days later an outbreak of the greenbug, Toxoptera graminum (Roud.), was discovered in the same general area. A study of weather records for the first 4 days of May showed that weather features particularly favorable for long-range aerial transport of insects could have enabled them to be carried to Minnesota from areas to the south and southwest, where they were known to be abundant. The possible prediction of future major outbreaks of the greenbug is discussed briefly.Keywords
