United States Patent 3,529,058 FEEDSTUFF FOR SILKWORM LARVAE Tetsuo Okauchi, Hirakata, Japan, assignor to Takeda Chemical Industries, Ltd., Osaka, Japan N0 Drawing. Filed Feb. 24, 1967, Ser. No. 618,313 Claims priority, application Japan, Feb. 24, 1966, 41/11,372 Int. Cl. A01n 9/36 US. Cl. 424-200 4 Claims ABSTRACT OF THE DISCLOSURE Weight of silkworm cocoons, and especially of cocoon layers, is increased by feeding the 4th instar silkworm larvae feedstuff containing a compound of the formula II R11I)R3 R2 wherein X is a member selected from the group consist ing of O and S, and each of R R and R is dialkylamino, or ethyleneirnino (aziridin-l-yl).
This invention relates to a method for increasing the weight of silkworm cocoons, especially of cocoon layers, and to appurtenant feedstuff for silkworm larvae. More particularly, this invention relates to the method which comprises feeding the 4th instar silkworm larvae feedstulf containing a compound of the formula wherein X is O or S, and each of R R and R is dialkylamino or ethyleneimino (aziridin-l-yl), the alkyl having a maximum of four carbon atoms and the ethyleneimino being unsubstituted or substituted by alkyl having a maximum of four carbon atoms; and to the said feedstufi itself.
Although many improvements in mulberry leaves, artificial feedstutts for silkworm larvae, race of silkworms and methods of rearing the larvae have been proposed for the purpose of increasing the weight of cocoons, none of these prior proposals has provided a satisfactory etfect in increasing the cocoon weight.
One object of the present invention is to embody a satisfactory method for increasing the weight of silkworm cocoons, especially of cocoon layers. Another object of the present invention is to provide an artificial feedstutf for rearing silkworm larvae, especially in 4th instar larvae These objects are achieved, and cocoons and cocoon layers of increased weight are obtained by the present invention, according to which the 4th instar silkworm larvae are reared on feedstufi containing compound (I) supra, while the weight of the cocoons rather decreases when any other instar silkworm larvae than the 4th instar are reared on the said feedstufi.
As compounds of Formula I, there may, for example, be used Hexamethylphosphoryl amide:

H20 CH1 As aforestated, in the method of the present invention, an increase of weight of silkworm cocoons, especially of silkworm cocoon layers can be attained by feeding a feedstuff containing compound (I) to the 4th instar silkworm larvae. As feedstuff containing compound (I), there may be employed, for example, mulberry leaves incorporated with compound '(I), or artificial feedstutf containing compound (I), together with conventional components of artificial feedstutf for silkworms.
Mulberry leaves incorporated with compound (I) may be prepared by, for example, spraying a solution of compound (I) onto fresh mulberry leaves, or immersing the leaves in the solution.
The quantity of compound (I) to be supplemented to the fresh mulberry leaves is practically about 0.005 to about 0.6% by weight relative to the fresh mulberry leaves.
The compound (I) may be supplemented to a conventional artificial feedstufi composed of eg. terpenes '(which may however be omitted), e-sitosterol with or without flavonoids, cellulose, powder, choline, nucleic acid or its derivatives, chlorogenic acid, etc., and sugar, inorganic phosphate, inorganic silicate, inositol, etc. As further per se conventional components of such feedstufr, which are helpful for the growth of silkworm larvae, there may, for example, be used agar-agar, sodium carboxymethylcellulose, methylcellulose, alginic acid; soybean powder, parched bean flour, defatted soybean powder, bean curd, dried fermented soybean powder, defatted and dried bean paste; cereal flour such as rice flour, barley flour, wheat flour, etc.; yeast products such as dry yeast, yeast extract, extracted fluid of yeast, extracted yeast cake; straw ashes;
and fish meal. These also serve as carrier. Further there may be included the following per se conventional nutritious components for the growth of silkworm larvae:
