Figure 3From: Evaluation and modeling of synergy to pheromone and plant kairomone in American palm weevilModeled additive responses (mean time in odorized arm) of American palm weevils (right color scale) to mixtures of synthetic aggregation pheromone (P) and natural odor of fermented sugar cane (K) in a 4-arm olfactometer under hypothesis of independent effects of P and K. Response surface Rad is a function of the amount of P+K mixture (3.10 3 to 30 ng/s) and of the percentage of P in mixture (0 to 100%) and shown from two 180° opposite positions. Planes at minimum and maximum responses are shown for reference. Experimental responses to nine P+K mixtures are shown as points (above the predicted response surface; see 2-D projections in Figure 2).Back to article page
