Northerly Movement of Corn Borer Moths in Southern Minnesota

Seventeen light traps were installed in 6 counties in southwest Minnesota in 1962 and 1963 and the nightly catches of moths of the European corn borer were recorded. The results show that moth catch was higher during nights with south winds and the nights immediately following such nights. This relation occurred over a large area and during the entire flight period. Moth popu1\u27otion in southern Minnesota was increased when south winds prevailed during the Right period. The trapping and recording were carried out by 15 FFA members, l 4-H member, and l adult farmer. The project demonstrates that these young people represent a valuable pool of human resources for use in salving certain scientific problems

Campaniform sensilla Patterns on the Wings of Drosophila

Campaniform sensilla have been described from the wings, mouthparts, legs, and other parts of the insect body. These small sense organs were known under several terms until Berlese ( 1909) applied the term campaniformi because of their dome, or bell-shaped character. Numerous functions have been suggested for these organs which seem to be stress receptors of some sort. Very few attempts have been made to utilize these sensilla as taxonomic characters
