Extraction and Separation of Custard Apple Seed Oil as a Natural Pesticide

For extraction of oil from the custard apple seed we use Soxhlet extraction equipment. With help of Soxhlet apparatus yield of extraction will be increase. The bio Pesticide from seed oil is effective and ecofriendly. It will help to reduce the pollution air as well as soil. There are various processes are available to produce Pesticide from custard apple seed. Scope of bio Pesticide in India is high. This will beneficial for farmers as well as producer. The % Recovery of biopesticide produce from the custard apple seed powder is more than 80 %. As the ration of feed to solvent increase the % recovery also increase. For 1:5 ration has highest recovery of biopesticide which up to 85%. Above 1:5 ratio increase the cost of solvent and negligible increase in recovery. Hence ratio for feed to solvent will be 1:5 as optimum ratio. Tests of susceptibility for larvae and imaginal stage of mosquitoes were realized to determine mortality and LC50 of mosquitoes. Chemical identifications showed that these extracts contain alkaloids and flavonoids compounds that probably confer their biological Pesticidal proprieties. On adult mosquitoes, significant Pesticidal effects were observed with methanol extracts of seeds of Annona squamosa.
