Definitions
- the present invention relates to an insecticidal composition
- an insecticidal composition comprising a mixture of a polymer binder and a suspension of one or more entomopathogens .
- Such a composition is known from US-5 , 141 , 744.
- water swollen pieces of water retentive polymers were added to an aqueous suspension of
- entomopathogens in the form of fungal pathogen ⁇ Beauveria bassiana) spores in order to prepare macrogels in a process called hydromacroencapsulation .
- the entomopathogens are suspended in an aqueous solution of a gel forming matrix in the presence of the polymer and thereafter gelated by means of a gelling agent for long time storage.
- the macrogel composition may thereafter be applied in particular sprayed on the spot .
- composition means that infection of in this case mosquitoes or other susceptible arthropods with the fungi is initiated instantaneously, and thereafter has a short effective working duration.
- composition according to the present invention that a release function concerning migration of entomopathogens through the polymer binder and through the external surface of the composition is created.
- the resistance experienced by the fungal spores or any other entomopathogenic agent and their degree and speed of migration can be influenced. Adjustment of the ratio allows for a longer effective period during which the potential harmful insects, if allowed to get in contact with the insecticidal composition, are infected with the migrated entomopathogens. This also has a
- the oily substance provides a carrier for the
- the composition may have the form of possibly pre- expanded spheres, but may also have the form of powder, or spray.
- the composition can be sprayed on a mosquito screen or netting, or cloth, or directly on surfaces visited by harmful arthropods in order to have the entomopathogenic agent destroy the insects before being capable of infecting humans or livestock with disease-causing pathogens or cause nuisance .
- the oil comprising the spores is prepared.
- the polymer is applied to the object and dried. Thereafter the oil spores suspension is sprayed onto the polymer. This has the advantage that the oil spores mixture is not subjected to higher temperatures of between 35-55
- a preferred embodiment of the composition uses polyvinylalcohol (PVA) , which is a water soluble synthetic polymer, which is not affected by oil and not toxic to the spores.
- PVA polyvinylalcohol
- PVA is also available on the market in variants that are not soluble in water of around 25 °C or lower.
- Such a PVA coating does not dissolve in rainwater.
- 50% soft PVA 50% water has been added, which was mixed with Shellsol T wherein the spores of Beaveria bassiana were stirred.
- this composition can be dried in the air and no forced drying is required. This embodiment showed very good results in terms of mosquito mortality .
- Beauveria bassiana spores in a 5 ml spore mix was stirred with Shellsol oil.
- 5 ml of a 10% polymer binder mixed with the oil-spore mix was applied on paper with a coating machine in a 12 ⁇ thick layer.
- Paper is a medium which absorbs oil very well. The mosquitoes if subjected during 2 hours to the coated paper all died within 15 days.
- the spores should preferably be dry and powdery on the surface and not binding too much to a sticky oil, fat or coating. Spores stay dormant inside the composition as they only germinate on and subsequently grow inside the mosquitoes and then need carbohydrates.
- bassiana spores in a concentration of 4 x 10 10 were still viable, infective and virulent to mosquitoes 7 months after being coated in Shellsol on paper. Thereafter all
- Insect attracting substances kairomones like 1- octen-3-ol, ammonia, 2 -oxopentanoic acid, and the like
- means to induce contact between harmful insects and the proposed formulations e.g. substrate colour
- the proposed formulations e.g. substrate colour
- means to reduce environmental influences e.g. UV light
- An upper limit of 55% spores can be included in the oily substance, and such a mixture can then be mixed in the binder in order to prepare a coating.
- insect growth regulators such as pyriproxifen and/or triflumuron to the composition.
