We evaluated the use of synthetic and living mulch with a reduced-risk insecticide for the control of silver leaf whitefly, Bemisia argentifolii Bellows and Perring, and aphids in zucchini, Cucurbita pepo L. Living mulch, buckwheat Fagopyrum esculentum Moench and two synthetic mulch (reflective and white) with and without reduced-risk insecticide (Imidacloprid [Admire 2F]) were evaluated in the fall of 2005 in Florida. Experimental design was a completely randomized block with five treatments including a control. Each treatment was replicated four times. Results from the yellow sticky traps and foliar counts showed that reflective and living mulch with Admire 2F had lower numbers of adult and immature whiteflies and aphids (apterae) than the standard white mulch. However, counts from the pan traps (alate aphids) indicated that that there were no significant differences between treatments with and without Admire 2F. Reduced-risk insecticide did not affect natural enemies as there were no significant differences between treatments with and without Admire 2F. In the case of the yields, reflective with Admire 2F was not significantly different from reflective alone while living mulch with Admire 2F had significantly higher yields than living mulch alone. Overall, reflective mulch with the reduced-risk insecticide reduced whitefly and aphid densities and had higher yields. The research indicates that additional reduction in the abundance of whiteflies and aphids can be achieved when mulches are combined with just a single application of imidacloprid.
