SCIENTIFIC NOTE Evaluation of Trimedlure Bait Field Duration under Florida Field Conditions
نویسندگان
چکیده
A study was conducted to determine the effect of trimedlure (TML) bait field duration on recovery of sterile male Mediterranean fruit flies, Ceratitis capitata (Wiedemann) under west central Florida conditions. Jackson traps baited with TML soft plugs were placed in residential (N = 80) and industrial (N = 40) settings, then monitored weekly. Traps were monitored to determine if TML bait at threeor sixweek field duration had a greater attractiveness towards C. capitata. In all but one instance, traps with three-week field duration achieved higher C. capitata yield than traps baited in the field for six weeks. However, no significant difference (P > 0.05) was found in trap yield as a result of bait age. Given these data, maintaining Jackson traps on six-week duration bait is more cost effective with no significant recovery loss due to attractiveness to sterile release C. capitata in a residential setting.

Improved attractants for Mediterranean fruit fly, Ceratitis capitata (Wiedemann): responses of sterile and wild flies to (-) enantiomer of ceralure B1.
Tests were conducted on wild Mediterranean fruit flies, Ceratitis capiata (Wiedemann), in Hawaii, Italy, and Kenya, and on sterile released flies in Florida and California with a new male attractant, (-)-ceralure B1. Compared on an equal dosage basis, Mediterranean fruit fly males were significantly more attracted to the (-)-ceralure B1 than to trimedlure in each of the sites tested except for ...

In a field test to examine attractancy of Mediterranean fruit fly, Ceratitis capitata (Wiedemann), relative to release rates, equal moles of racemic ceralure B1 and trimedlure isomer C were compared on cotton wicks. Data were collected at 2, 4, and 7 d. The substrates were analyzed for longevity and overall persistence in the field. Ceralure B1 was equally attractive as trimedlure C for the fir...

Captures of nontarget insects inside fruit fly (Diptera: Tephritidae) traps placed in native habitats at three localities on Kauai Island, Hawaiian Islands were evaluated. Significantly greater nontarget capture rates were found for traps separately baited with four different attractants, methyl eugenol (five species and two morphospecies), cue-lure (two species), trimedlure (three species and ...
