            Title: A study of Krumighna (Pesticidal)  Property of koshamra seeds (Schleichera oleosa (Lour) Oken.)

          Dr. S. S. Khilari   had submitted her dissertation in 1998 Year, for the P.G. degree M.D. Dravyaguna (Ayurvedic Pharmacology). Her guide was Dr. A. P. Deshpande & research center was Tilak Ayurved Mahavidyalaya, Pune (M.S.) India. This thesis is written in English & submitted to University of Pune.

            Dr. Khilari   had done an experimental study of koshamra seeds

 (Schleichera oleosa (Lour) Oken.) to find out its pesticidal (Krumighna) activity against the insect of stored food grain.

          This experimental study was carried out on 2 types of food grains, sorghum & green gram, which was common & the insects selected was also common, namely S. oryzae & C. maculates.

          The 100 Gms sample of sorghum & green gram was taken in plastic jars & mixed with powder at concentration of 1, 2, 3, 4, 5 gm.  In each replicate 10 adult insects were released. Control group of both untreated 100 gm food samples was also included.

          o.05 g. of test drug powder was taken in 2 different plastic jars & 10 same adult insects were released in jars & dead insect count were taken at the intervals of every 24 hrs days in both samples.

          The research work was concluded as follows –

1)    The data indicated that koshamra seed powder was 100% effective against all S. oryzae & C. maculates at all concentrations in both the samples.

2)    The motility of insects in both the treated samples has become less within 24 hrs.

3)    There is no change in number of insects for 5 days in both the untreated samples.

4)    There is no growth observed in koshamra treated food grain.

5)    Heavy infestation & damage of grain was observed in both the untreated samples after 40 days.

In short koshamra seeds showed Incecticidal (Krumighna) property due to  its pungent, bitter taste.
