Bombyx mori breeding. Silkworm breeding is aimed at the overall improvement of silkworm from a commercial point of view. The major objectives are improving fecundity (the egg-laying capacity of a breed), the health of larvae, quantity of cocoon and silk production, and disease resistance. Healthy larvae lead to a healthy cocoon crop. Health is dependent on factors such as better pupation rate, fewer dead larvae in the mountage, shorter larval duration (shorter larval duration lessens the chance of infection) and bluish-tinged fifth-instar larvae (which are healthier than the reddish-brown ones). Quantity of cocoon and silk produced are directly related to the pupation
The Silkworm to stage his disappearance, rewrote "Bombyx Mori", killed Quine and framed Leonora for the crime. Tassel attempts to flee the party only to be quickly caught and arrested, which Strike and Robin planned in advance. Sometime later, Leonora is released from prison, Fancourt acknowledges the original "Bombyx Mori" manuscript's literary value, and Strike tells Robin that he enrolled her in investigative training courses as a Christmas gift. Much like "The Cuckoo's Calling", "The Silkworm" was met with critical acclaim, selling more copies than its predecessor in its opening weeks. Val McDermid from "The Guardian" gave the novel a positive review,
