Claims8
A formulation for controlling Tephritid fruit fly, Bactrocera cucurbitae comprising phagostimulant and additional agents;
- wherein the phagostimulant is a combination of ethyl hexanoate esters, gamma octalactone, delta octalactone, acetic acid, β-ocimene, cis-ocimene and a mixture of cucurbitacin A, B & D in the ratio ranging from 2:3.5:2:5:4:1:1 to 12:3:0.5:9:3:5:1;
- and the additional agents comprise a stabilizer, an emulsifier, a thickening agent, and a temperature stabilizing agent.
A process of preparation of a formulation for controlling Tephritid fruit fly, Bactrocera cucurbitae comprising steps of:
- a. preparing solution A, by adding phagostimulant one by one in a quantity to 99% ethanol;
- b. preparing solution B, by mixing a stabilizer, an emulsifier, a thickening agent and a temperature stabilizing agents in a quantity with sterile distilled water;
- and
- c. mixing the solutions A and B in the ratio of 1:-1.5 to 1:12 to obtain the formulation;
- wherein the phagostimulant in solution A is a combination of ethyl hexanoate esters, gamma octalactone, delta octalactone, acetic acid, β-ocimene, cis-ocimene and a mixture of cucurbitacin A, B & D, in the ratio ranging from 2:3.5:2:5:4:1:1 to 12:3:0.5:9:3:5:1;
- and wherein the stabilizer is glycerol, polyethylene glycol (PEG), or polyvinyl alcohol (PVA) in the range of 0.5-10% w/v;
- the emulsifier and the thickening agent are selected from a group consisting of gums, starches, and polysaccharides and are together present in the range of 0.5 to 10% w/v;
- and the temperature stabilizing agent is ammonium carbonate, ammonium bicarbonate, diammonium phosphate, or ammonium acetate in the range of 0.05 to 5% w/v.
