DEET and other repellents are inhibitors of mosquito odorant receptors for oviposition attractants.

In addition to its primary function as an insect repellent, DEET has many "off-label" properties, including a deterrent effect on the attraction of gravid female mosquitoes. DEET negatively affects oviposition sites. While deorphanizing odorant receptors (ORs) using the Xenopus oocyte recording system, we have previously observed that DEET generated outward (inhibitory) currents on ORs sensitive to oviposition attractants.

Repellency of Naturally Occurring or Related Compounds, DEET, and Para-Menthane-3,8-Diol to Bed Bugs (Hemiptera: Cimicidae).

Bed bugs, Cimex lectularius L. (Hemiptera: Cimicidae), have become a major health nuisance in the past 20 ysin cities and elsewhere throughout many areas of the world. Few studies have reported on repellent compounds that could reduce their transport in luggage.

Enhanced Response of Halyomorpha halys (Hemiptera: Pentatomidae) to Its Aggregation Pheromone with Ethyl Decatrienoate.

The invasive stink bug species, Halyomorpha halys (Stål) (Hemiptera; Pentatomidae), severely damages multiple agricultural commodities, resulting in the disruption of established IPM programs. Several semiochemicals have been identified to attract H. halys to traps and monitor their presence, abundance, and seasonal activity.

Relatively Small Quantities of CO2, Ammonium Bicarbonate, and a Blend of (E)-2-Hexenal Plus (E)-2-Octenal Attract Bed Bugs (Hemiptera: Cimicidae).

Bed bugs, Cimex lectularius L., feed on humans, have increased exponentially in the past two decades in many major cities throughout the world, have caused intense infestations, and have become a significant health concern. Improved traps are needed to detect early infestations, to assess control programs, and for control of bed bugs.

Quasi-double-blind screening of semiochemicals for reducing navel orangeworm oviposition on almonds.

A three-step, quasi-double-bind approach was used as a proof-of-concept study to screen twenty compounds for their ability to reduce oviposition of gravid female navel orangeworm(NOW), Ameylois transitella (Lepidoptera: Pyralidae). First, the panel of compounds, whose identity was unknown to the experimenters, was tested by electroantennogram (EAG) using antennae of two-day old gravid females as the sensing element. Of the twenty compounds tested three showed significant EAG responses.
