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. Mix equal parts ammonia and water in a bowl. The subdivisions of the arachnids are usually treated as orders. [citation needed], Many research works have focused on the genetics of silkworms and the possibility of genetic engineering. Healthier larvae have greater pupation rates and cocoon weights.
