A Rapid Method for Artificially Infesting Research Plots with Heliothis Eggs

G.D. Thompson, D. L. Paroonagian, P.K. Leonard, L.A. Pavan and S.P. Nolting


This paper expands on the previously described technique of artificially infesting research plots with eggs of Heliothis virescens suspended in a gum xanthan solution. Advances in preparation of gum xanthan egg suspensions and development of mechanized application techniques are described. Use of these techniques has been found to greatly reduce labor requirements from more traditional manual techniques. Experimental results obtained using this method do not exactly mirror what occurs in naturally infested plots but they do allow the researcher to better balance his work load and produce data when natural infestations are not present.
