玉小石・小石丸
営繭 cocooning
お蚕さん『小石丸』と『玉小石』の1齢から2齢の幼虫をいただいてから36日目。
やっと2頭が繭になりました。
お蚕さんは系統によって発育日数が異なるそうですが、この幼虫を育てていた他のかたよりもずいぶん営繭が遅かったです。
通常は孵化して25日目くらいには繭になるので、それに比べても時間がかかりました。まだ幼虫はいますが、2頭が無事に繭になったので安心です。
糸を吐き始めてから約1日半で中の幼虫がみえなくなり、2～3日で繭が完成します。
It’s been 36 days since I received the 1st and 2nd instar larvae of the silkworms “Koishimaru” and “Tamakoishi”.
Finally, the two became cocoons.
The number of days it takes for silkworms to develop varies depending on the lineage, but this larva was much slower to cocoon than other people who were raising it.
Silkworm larvae usually turn into cocoons on the 25th day after hatching, so it took even longer than that. There are still larvae, but I’m relieved that two of them have successfully cocooned.
The larva inside is no longer visible after about a day and a half after the thread begins to be spewed out. The cocoon is completed in two to three days.
