Stabilized biological pesticides comprising Chromobacterium species, filtrate, supernatant, extract or pesticidally active substance derived therefrom with pesticidal activity having improved shelf life due to maintenance of physical uniformity and longer insecticide activity after use due to higher resistance to degradation when exposed to sunlight are disclosed.
1. A method for modulating infestation of a pest, wherein said pest is selected from an Acari, Muscidae, Drosophilidae, Anthomyidae, Aphididae, Triozidae, Tenebrionidae, and Scarabaeidae, in a location where modulation is desired comprising the step of: applying an amount of a composition comprising a supernatant of a whole cell broth, a filtrate of a whole cell broth, an extract of a whole cell broth or a whole cell broth collected from Chromobacterium subtsugae Nov strain (NRRL B-30655) fermentation, effective for modulating said infestation.
2. The method according to claim 1 , wherein the location where modulation is desired is on a plant, plant seed or in soil.
3. The method according to claim 1 , wherein said pest is an Acari and the Acari is a mite.
4. The method according to claim 3 , wherein said mite is a Tetranychus sp.
5. The method of claim 4 , wherein the Tetranychus sp. is Tetranychus urticae.
6. The method according to claim 1 wherein said pest is selected from a Musca sp., Myzus sp., Bactericera sp., Cyclocephala sp., Alphitobius sp., Drosophila sp., Delia sp., Rhizotrogus sp., Popillia sp., Anomala sp., and Otiorhynchus sp.
7. The method according to claim 1 , wherein said pest comprises Musca domesitcas, Drosophila suzukii, Delia radicum, Myzus persicae, Bactericera cockerelli, Alphitobius diaperinusxi, Cyclocephala lurida, Rhizotrogus majalis, Popilla japonica, Otiorhynchus sulcatus , or Anomala orientalis.
8. The method of claim 1 , wherein the pest is a Scarabaeidae larva.
9. The method of claim 1 , wherein the composition comprises supernatant, filtrate, or extract from the whole cell broth.
10. A method for modulating infestation of a pest, wherein said pest is selected from an Acari, Muscidae, Drosophilidae, Anthomyidae, Aphididae, Triozidae, Tenebrionidae, and Scarabaeidae, in a location where modulation is desired comprising the step of:
applying an amount of a composition comprising a whole cell broth collected from Chromobacterium subtsugae Nov strain (NRRL B-30655) fermentation comprising violacein, deoxyviolacein, and/or chromamide A, effective for modulating said infestation.
