what is/ are
major brain proteins 112kDa, 84kDa
larval hemolymph protien (LHP)

I got this from a 5 minute search spree on the net. Hope it can help.

juvenille hormone = A hormone secreted by insects from a pair of endocrine glands close to the brain. It inhibits metamorphosis and maintains the larval features.

Prothoracicotropic Hormone (PTTH) = Molting and pupation require the hormone, PTTH, secreted by a two pairs of cells in the brain of the larva. If these cells are cut out of the brain of a full-grown larva, pupation does not occur. This is not because of the trauma of surgery; if transplanted somewhere else in the caterpillar's body, pupation occurs normally.

PTTH is a homodimer of two polypeptides of 109 amino acids.
PTTH does not drive pupation directly but, as its name suggests, acts on the prothoracic glands


Prothoracic gland: Either of a pair of endocrine glands located in the prothorax of certain insects and regulating molting.
