Interpretive Summary: Antifreeze is often used as the capture liquid in insect traps for its preservation and evaporation attributes. In tests reported herein, fruit fly traps using non-toxic household propylene glycol based antifreeze captured significantly more Mexican fruit flies than did traps with the automotive antifreeze. Automotive antifreeze has a characteristic odor due to the additive tolytriazole. The absence of the odor may be responsible for the increased captures. Whether better or equal in efficacy, fruit fly trapping programs should consider using the non-toxic formulation as an environmentally friendly alternative over the automotive antifreeze, which contains a number of hazardous compounds.

Technical Abstract: Antifreeze is often used as the capture liquid in insect traps for its preservation and evaporation attributes. In tests reported herein, fruit fly traps using non-toxic household propylene glycol based antifreeze captured significantly more Anastrepha ludens than did traps with the automotive antifreeze. Automotive antifreeze has a characteristic odor due to the additive tolytriazole. The absence of the odor may be responsible for the increased captures. Whether better or equal in efficacy, fruit fly trapping programs should consider using the non-toxic formulation as an environmentally friendly alternative over the automotive antifreeze, which contains a number of hazardous compounds.
