3.1. Sanitation scores
Based on Tsai's (2010) criteria, Facility A scored higher than Facility B in terms of the overall level of sanitation present in each facility. Facility A was classified as having “Superior” sanitation, while Facility B was classified as having “Good” sanitation. Facility A generally observed good operational practices in almost every area of the facility, while Facility B was found lacking in several areas. Among them, 1) Facility B had large piles of raw or processed material left out for extended periods of time, 2) doors were left open to the outside environment for indeterminate periods of time, and 3) facility conditions allowed for the build-up of moisture and dust. In general, Facility A did a better job addressing these aspects of facility sanitation.
3.2. Fumigation bioassay results
The results of bioassay data indicate that an effective dose of Sulfuryl fluoride permeated all areas of each facility (Fig. 1). Facility A had 100% mortality of adult beetles in vials (Avg. = 0 ± 0 beetles alive; Control Avg. = 5 ± 0 beetles alive) and 100% mortality of beetle eggs (Avg. = 0 ± 0 beetles alive; Control Avg. = 3.8 ± 0.29 beetles alive). Facility B had 99.1% mortality of adult beetles (Avg. = 0.044 ± 0.042 beetles alive; Control Avg. = 5 ± 0 beetles alive) and 94% mortality for beetle eggs (Avg. = 0.3 ± 0.077 beetles alive; Control Avg. = 3.8 ± 0.39 beetles alive). The apparent lower effectiveness of Facility B's fumigation is due to some of the adult and egg vials being placed in an area of the facility that was fogged with an aerosol, but not fumigated. The vials therefore physically shielded the specimens from the aerosol. When un-fumigated vials were removed from the mortality average, both adult and egg mortality increased (Adult avg. = 0 ± 0 beetles alive; Egg avg. = 0.18 ± 0.061 beetles alive). Overall, the results of both bioassays predict a high effectiveness of both facilities' fumigation with an expectation that monitoring data results should be similar.
