Total trap captures ofLonchaea striatifrons Malloch (Diptera: Lonchaeidae) for all periods in ethylene glycol antifreeze, propylene glycol antifreeze, mineral oil, and control traps, respectively, were 74, 207, 0, and 0 insects. Fixed effects of period (F = 26.61, df = 3, 11.6;P < 0.0001) and attractant trap type x period interaction (F = 4.30, df = 3, 11.6;P = 0.0293) were significant. Significantly moreL. striatifrons were captured in traps containing propylene glycol antifreeze than in ethylene glycol antifreeze (21-d trapping period). Additionally, ethylene glycol antifreeze (28-d trapping period) and propylene glycol antifreeze (21- and 28-d trapping period) captured significantly moreL. striatifrons, than did mineral oil and control traps. These findings suggest that ethylene glycol antifreeze and propylene glycol antifreeze are more attractive toL.striatifrons than to mineral oil and decaying insects. Because L. striatifrons is known to breed in rotting plants (Hardy and Delfinado 1980), it seems that decaying insects are not attractive, because trap captures were significantly lower for both mineral oil and control traps.
