Table 1. House fly attraction to plant materials infested with honeydew-producing insects.

Treatment	Control	Treatment mean captures ± SEM	Control mean captures ± SEM	P-value	% Response to treatment	Reps
Citrus mealybug on squash	Nothing	13.68 ± 0.99	7.21 ± 0.48	p < 0.0001	65.5	28*
Citrus mealybug on squash	Uninfested squash	19.1 ± 1.34	12.6 ± 0.87	p = 0.0028	60.3	16
Uninfested squash	Nothing	8.75 ± 1.29	9.88 ± 1.38	p = 0.62	47.0	8
Needle-damaged squash	Uninfested squash	9.57 ± 2.77	8.43 ± 1.65	p = 0.79	53.2	7*
Pea aphid on faba bean plant	Faba bean plant, not infested	18.4 ± 1.34	10.3 ±1.26	p = 0.012	64.1	8

Fifty female flies were used per replicate, with 8 replicates per 24 hr bioassay period. Data were analyzed with ANOVA for the first comparison and by paired t-test for the remaining comparisons within each row. “% Response to treatment” is the total number of house flies captured on the treatment over the total flies captured on both treatment and control.

*Indicates that 1 or more replicates were discarded due to a cage failure allowing flies to access the test material within a beaker.
