摘要:
The present invention relates to producing novel strains of green alga specifically engineered to produce an improved engineered compound over naturally occurring larvicide compound. In particular, genes were isolated and sequenced encoding naturally occurring larvicides produced by Bti (Bacillus thuringiensis subsp. israelensis), e.g. Cry proteins, were redesigned, synthesized, then introduced as heterologous transgenes into strains of Chlamydomonas reinhardtii for producing motile larvicidal-green algae specifically lethal to larvae of mosquitoes and black flies in water systems. Thus green alga (i.e. eukaryote) as motile biocontrol agents are contemplated for use to reduce the number of adult mosquitoes that transmit disease, such as West Nile virus, dengue, encephalitis, and malaria, in addition to reducing the number of adult black flies, in a safe and sustainable manner.

摘要:
The invention is directed to a topical insect repellent with extended duration of protection and that was obtained by combining natural and organic plant essential oil compounds. The new natural repellent exhibits the longevity and repellency that is comparable to or better than N,N-diethyl-m-toluamide (DEET), a synthetic compound employed in almost all commercial formulations, while at the same time is more acceptable than DEET, which has an unpleasant odor, imparts a greasy feel to the skin, and carries certain health concerns when used on children. The inventive insect repellent, formulated in a suitable carrier repels and incapacitates flying insects and other pests, such as mosquitoes and other biting flies or insects, thus demonstrating the utility of the novel insect repellent for protecting pets and livestock as well as humans. The invention provides an effective means to repel insects, without having deleterious effects on people, pets or the environment compared with prior insect repellant formulations. The repellant formulation disclosed herein may employ natural or organic active ingredient, e.g., plant essential oil compounds.

摘要:
The compositions comprise an effective repellent amount of one or more monoterpenoids, one or more sesquiterpenoids or a blend of one or more monoterpenoids and one or more sesquiterpenoids in combination with a carrier, wherein the compositions are formulated to repel a target pest from a target area. In one embodiment, the one or more monoterpenoids, and/or one or more sesquiterpenoids are from a biorational source, such as a plant volatile. In one embodiment, the one or more sesquiterpenoids are oxygen-containing sesquiterpenoids. In a particular embodiment, the plant volatile is a monoterpenoid, such as “nepetalactone” (or the individual nepetalactone isomers) derived from catnip (Nepeta cataria). In another embodiment, the plant volatile is additionally or alternatively a sesquiterpenoid derived from the fruit of the Osage orange tree (Maclura pomifera), Siam wood or the Amyris plant. Such compositions have repellency, including long term repellency, against arthropods.
摘要:
The invention provides compositions and methods useful in repelling target pests, such as insects from target areas. The compositions comprise mixtures or solutions of at least one repellent composition. The compositions of the invention preferably include an effective amount of evening primrose oil (“EPO”) to repel a target pest from a target area, such as animals, humans, plants or building structures, along with a carrier. The repellent composition may include a combination of EPO with another plant extract oil and a combination of EPO with catnip oil, optionally combined with another plant extract oil. The method for repelling target pests from animals comprises contacting a target area with the repellent composition to repel the target pest from the target area. The method also reduces transmission of infectious diseases transmitted by target pests by reducing contact of the pest with target areas.
