cis-Jasmone has been discovered to be useful as a semiochemical that changes the behaviour of insects and/or the physiology of plants. It has direct signalling roles with plant-feeding aphids, in attraction of aphid predators and parasitoids, and may act as an airborne signal inducing production of volatile plant semiochemicals, including the monoterpene (E)-β-ocimene, that stimulate foraging by parasitoids. It is an extremely benign compound having, to human beings, a pleasant aroma and gives a long-lasting effect after removal of the stimulus.

A bed bug trap includes heat, carbon dioxide and/or semiochemicals (pheromones and/or kairomones), to attract and trap bed bugs. The trap may be combined with the appearance and/or function of another appliance, such as an air freshener. The release of semiochemicals may be combined with the release of air freshening compositions. The bed bug trap may provide one attraction mode, or two attraction modes, namely one which uses heat, carbon dioxide and/or kairomones to attract bed bugs seeking a meal, and the other which uses pheromones to attract bed bugs seeking a safe harbor, i.e. a hiding place. The bed bug trap may be combined with a wide variety of appliances, such as air fresheners, alarm clocks, clock radios, humidifiers, desk or table lamps, power bars, etc..

A composition including a bait and a borate is used to mitigate a population of target insects and/or mollusca. The composition may include attractive by-products of agriculture and manufacturing with or without semiochemicals or biopesticides prepared as point source units (such as pellets or microcapsules). The by-products attract insects and/or mollusca to a food source for the purpose of mitigating the target organism. The bait is combined with borates and is pelletized and/or encapsulated into micron size particles. The pelletized and/or encapsulated particles are broadcast (spread) over areas infested with the target insect. The insects ingest the composition and regurgitate the composition to the remainder of the insect population. Significant mitigation of the population of the target insects results with little to no effect on the environment. The composition is also passed on to the next generation due to cannibalism of the target insects. A feed through process wherein the composition is fed to an animal and is contained in the manure of the animal deposited as a point source location. The composition is either mixed in with the food of the animal or placed directly in the gut of the animal using a ball and gun method. The target insects are attracted to the manure and upon ingesting the manure, ingest the composition and are dispatched.

The invention relates to a screening method of sustained-release materials for Monochamus ahernatus Hope semiochemicals. With the sustained release rate and the ratio of attractant components taken into account, a weighing method and a gas chromatography analysis method are adopted for screening the sustained-release material for the Monochamus ahernatus Hope semiochemicals.

Experimental results show that the four kinds of sustained release materials have certain advantages and disadvantages in terms of sustained release effect. The screening method of the sustained-release materials for the Monochamus ahernatus Hope semiochemicals can provide technical reference for developing a more economical and efficient attractant for Monochamus ahernatus Hope.
