Bombyx mori and Sericiculture.
GUERIN-MENEVILLE publishes (R. Z. 1870, pp. 45-48, 72-80, 214-224)
his usual series of reports on Sericiculture. He records the continued success
of Baron de Bretton, Madame Baumann, and M. Chazy in rearing Antheraa
yama-mai; publishes a report from the French minister in Japan relative to
the habits of the insect in that country, and the means adopted to rear it.
(Of the eggs sent to France by this gentleman only 20 per cent, were fertile;
and most of these hatched before the oaks were in leaf.) Guerin-Meheville
also records an hermaphrodite specimen of Bombyx mylitta, bred by M. Henzi,
and thinks that the epidemic among B. mori is gradually decreasing.
M. Renard has sent eggs of a very strong Chinese race to France ; the silkworms
were reared by different experimenters with varying success. Guerin-
Meneville attributes the epidemic to unwholesome food; and, while not
placing much confidence in M. Pasteur's views, recommends that the matter
should be further investigated.
DELANDRE (R. Z. 1870, pp. 121-128) reviews the various publications on
Sericiculture which have recently appeared'in England, Holland, Austria,
Prussia and Sweden. He publishes a letter from O. Zik, giving details of
recent experiments in Austro-Hungary (pp. 153-158), and publishes (pp.
189-192) an account of the progress of Sericiculture in Cochin China and
Cambodia.
A. WALLACE has published (Ent. Ann. 1871, pp. 101-107) some notes on
Sericiculture, chiefly with reference to the feasibility of rearing Bombyx
mori in England and the British colonies. For further remarks see Proc.
E. Soc. 1870, pp. 10,11.
A. B. FARN has published an abstract, with useful additional notes, of a
valuable official Report (No. 1) by Mr. Adams, secretary to H.M. Legation
in China, on the " Central Silk Districts of Japan." Ent. v. pp. 87-91.
On the Japanese silk-trade, see Proc. E. Soc. 1870, pp. 21, 22.
PASTEUR has published a valuable work on the diseases of silkworms (vide
