Sticky Trap Lure Attractants.
Attractants
Geraniol and eugenol are effective attractants and are used as lures in traps for the Japanese beetle, Popillia japonica Newman, and methyl-eugenol has been used to trap oriental fruit fly, Dacus dorsalis Hendel (Vargas et al., 2000). Cinnamyl alcohol, 4- methoxy-cinnamaldehyde, cinnamaldehyde, geranylacetone and α-terpineol are also attractive to adult corn rootworm beetles, Diabrotica sp. (Hammack, 1996; Petroski and Hammack, 1998). The essential oil and a number of extracts of Rosmarinus officinalis L. in solvents of increasing polarity have been isolated, and their components identified and tested as pest control agents. Ethanol and acetone extracts attract grape berry moth, Lobesia botrana. However, none of the extracts had a significant effect on western flower thrips, Frankliniella occidentalis, which is attracted by 1,8-cineole, a major essential oil component (Katerinopoulos et al., 2005). Lemon essential oil is distilled from the peels of Citrus limonum. It has a light yellow color and a characteristic lemon aroma. Lemon essential oil contains several terpenes and geraniol, which have all been shown to attract thrips, fungus gnats, mealybugs, scale, and Japanese beetles. Adding this oil to the insect-a-peel, thrips/leafminer blue trap, or the yellow aphid/whitefly sticky trap will attract these unwanted pests and capture them on the trap (http:// www.arbico-organics.com/1610075.html). Compositions of cis-jasmone were found to effectively attract adult Lepidoptera. The cis-jasmone may be used alone or in combination with one or more other volatiles of the Japanese honeysuckle flower, particularly linalool and/or phenylacetaldehyde. By attracting the adult Lepidoptera to attracticidal baits and/or field traps, the attractants are useful for the control and monitoring of these agricultural pests (Pair and Horvat, 1997). Similarly, natural essential oils have shown a high attractiveness for greenhouse whitefly, Trialeurodes vaporariorum Westwood. Greenhouse whitefly reacted particularly intensively to sandalwood oil, basil oil, and grapefruit oil. After the application of aromatic substances on yellow sticky traps, the number of insects caught increased significantly amounting to 487.64, 483.20, and 333.09%, respectively (Górski, 2004). Thus, natural essential oils or their constituents could be useful in the monitoring of pests, at least greenhouse whitefly in the present case. Basically if you have a source for essential oils you can incorporate them with the sticky traps with good success.Without the "lure" the traps are just a color type lure attractant.Our Whole foods has some of the above.I am experimenting with orange,lime peels right now.
