Research Project: Evaluation of a Three-lure (Trimedlure, Methyl Eugenol and Raspberry Ketone) Detection Trap Against Mediterranean Fruit Fly, Oriental Fruit

Location: Tropical Crop and Commodity Protection Research

Project Number: 5320-22430-025-22
Project Type: Trust

Start Date: Aug 01, 2011
End Date: Sep 30, 2013

Objective:
1. Test the performance of TML, C-L/RK and ME detection traps with a novel Farma Tech solid 3-lure and insecticide (TMR-Mallet) formulation under Hawaii conditions (Kauai Coffee). 2. Test the performance of TML, C-L/RK and ME detection traps with a novel Farma Tech solid 3-lure and insecticide (TMR-Mallet) formulation under California climatic conditions against “TML, ME and C-L/RK responding” fruit flies. 3. Conduct chemical analyses of FarmaTech wafers weathered in California.

Approach:
1. In Hawaii captures of Medfly, oriental and melon fruit flies will be determined in traps placed in Kauai Coffee orchards in Hawaii where Medfly, oriental fruit fly and melon fly are abundant in the same locality. 2. After further confirmatory data is obtained weathering trials will be done in California. Bioassays will be done in Hawaii. 3. Experimental design will consist of 4 replications of each of the treatments (4 weathered and 4 fresh wafers) tested in a completely randomized block design (Vargas et al. 2005). 4. By comparing mean number of flies captured inside traps on successive weeks, the relative ‘attraction” of dispensers will be determined at prescribed intervals. TML, ME and C-L trap capture data for Medfly, oriental fruit fly and melon fly (mean number flies/trap/wk) will be subjected to analysis of variance (Proc GLM), and means separated with a Least Significant Difference (LSD) test at the P = 0.05 level by week. 5. Samples for lure and pesticide decay will be sent to FarmaTech International (North Bend, WA) for chemical analysis using GLC analysis. Rates of lure and pesticide decay of the TMR stations will be determined and modeled.
