Figure 11. Average Production Value Attributable to Honey Bees

A population increase of 1.411 will lead to a pollination rate increased by the same ratio. Thus, we can infer
from the data that there will be an increase of 1.411 in the total crop yield due to pollination by bees.
By multiplying the annual APVAH with the EEHLS of the proposed supplement, the Optimized Economic Impact
of the Potential Cure(APVAH) can be derived. Applying the values calculated above, it is shown that the OEIPC
will be 19,188.56 million USD, a 5,596.66 million USD increase.

III. Conclusion

1. Results
A one-way ANOVA revealed the significance of the presence of E. avium on the lifespan of honey bees. The
30 samples treated with E. avium and their supernatant had an average lifespan of 10.46 days (SD = 3.34); the 30
samples treated directly with E. avium had an average life span of 8.6 days (SD = 2.14), and the 10 samples of
control had a mean of 8.5 (SD = 1.43). According to one-way ANOVA, The effect of E. avium treatment, therefore,
was significant, F(2,67) = 4.14, p=.02.
To test whether the average lifespan of A. mellifera would increase when supplemented with E. avium and their
supernatant, we used a t-test with an alpha level of .05. The average longevity of A. mellifera supplemented with
E. avium and their supernatant was 10.46 days (SD = 3.34), while the control group resulted in an average of 8.5
days with SD of 1.43. According to the t-test, it is significant that the samples treated with E. avium and their
supernatants reported longer life expectancy (M = 10.46, SD = 3.34) than did the controls who were fed only
untreated sugar cubes, t(29) = 3.21, p = .00.

2. Discussion
The results of the study unequivocally support both hypotheses 1 and 2.
The data on the economic value of honey bee pollination clearly proved hypothesis 1, as it showed to contribute
billions of dollars to the U.S economy. The study actively assessed the economic significance of pollination by
honey bees. By applying the method of Morse and Calderone, the economic value of pollination by bees was
calculated. 26 major crops, partially or entirely reliant on honey bees for pollination, were assessed. Calculations
showed how bees contributed to nearly half (52%) of all entomophilic crop yields.
