Using a spray tower to simulate aerially applied liquid sprays, three doses of Spinosad (a bacteria derived product) were each applied to grasshoppers and pots of growing grass separately on 7 Sept. For each dose, untreated grasshoppers were confined on treated grass, treated grasshoppers were confined on untreated grass and treated grasshoppers were confined on treated grass. Untreated grasshoppers were confined on untreated grass as a control. Grasshoppers treated with Fyfanon ULV (malathion) were confined on grass treated with Fyfanon as a standard for comparison. All spray treatments were applied at an equivalent total volume of 32 fluid oz/acre. Spinosad treatments were applied in distilled water and Fyfanon was diluted and applied in oil. The study design consistedof 10 replicates per treatment. Each replicate consisted of a caged pot of grass containing five fourth instar grasshoppers. Pots were 4 inches X 4 inches square with a 9 inch high cage attached and contained grass approximately 4 inches high at time of treatment. Caged grasshoppers were held at 78°2±°F and a photoperiod of 14:10 (L:D). Dead grasshopperswere removed from the cages and mortality recorded daily. |
