The index values fall between +1 and -1, the positive index value denotes more bedbugs are attracted in the treated arena than the control, thus, indicate the attractant property of semiochemical
products consist of the active ingredients, associated stabilizers and the release device or formulation that emits the actives at the desired rate over the required field life span.
SharkDefense has developed and tested shark-specific repellents, including semiochemicals
, gustatory compounds and metal alloys.
Eleven funnel traps baited with manuka oil lures (Synergy Semiochemical
For example, knowing the original host specificity of the beetle may explain its unusual semiochemical
ecology (Kendra et al.

disruption of host finding in the southern pine beetle.
A number of mechanisms for AR have been hypothesized, among them the resource concentration hypothesis, the enemies hypothesis, the semiochemical
diversity hypothesis, the repellent plant hypothesis and the attractant decoy hypothesis (Tahvahnainen & Root 1972; Root 1973; Atsatt & O'Dowd 1976; Russell 1989; Jactel et al.
Most ambrosia beetles are generalists that colonize dead or moribund trees, and as a result, are attracted to ethanol (Miller & Rabaglia 2009), a semiochemical
indicative of tree decay; however, since X.

mixture released by the least-preferred cultivar was more repelling than that of the most preferred cultivar.
Each of these sesquiterpenes has been implicated previously as a host-based semiochemical
for other species of wood-boring beetle.
New roles for cis-jasmone as an insect semiochemical

Recently, the electroantennogram (EAG) has been widely used in studies on semiochemical
