Discussion
- Silk production is assumed to increase [p_M] by a factor s_S after [E_R] > s_s * max [E_R]
Facts
- Imagos do not feed (Ref: VukaSnez2012)
- The larva starts producing silk after day 21 when they start spinning a loose cocoon for pupation (Ref: ImurSinh1986)
- Imagos do not feed (Ref: VukaSnez2012)
- Larvae not produce silk only to build the cocoon, buy also spin silken threads wherever they go (as a result they spoil more than they consume in stored grain products) (Ref: VukaSnez2012)
