Bursicon as a Potential Target for Insect Control
2012Bursicon is an insect heterodimeric neuropeptide hormone which binds to a specific G protein-coupled receptor, Drosophila leucine-rich repeats-containing G-protein-coupled receptor 2 (DLGR2) and regulates various aspects of cuticle tanning (sclerotization and melanization) and wing expansion in diverse insect orders.

Is tubulin the sole antigen recognized by a putative anti-bursicon antibody?
Comparative Biochemistry and Physiology Part B: Biochemistry and Molecular Biology, 1999A 56-kDa polypeptide suspected to be the tanning hormone 'bursicon' was analyzed using the monoclonal antibody (mAb) 01C10 of Song and Ma. We studied the beetle Tenebrio molitor, for which data on bursicon have been recently published. After purification by two-dimensional gel electrophoresis of brain proteins, the immunoreactive 56-kDa polypeptide was

Bursicon and neuropeptide cascades during the ecdysis program of the shore crab, Carcinus maenas
General and Comparative Endocrinology, 2013Very little is known regarding the release patterns of neuropeptides involved in ecdysis of crustaceans compared to insects. In particular, the dynamics of release of the insect cuticle hardening hormone bursicon, which has only recently been discovered in crustaceans, is unknown.

Control of cuticular tanning in the cockroach: Bursicon release by nervous stimulation
Journal of Insect Physiology, 1967Abstract Severing the central nerve chord of Periplaneta americana stops the release of the tanning hormone (bursicon) from the terminal abdominal ganglion. Disrupting the stomatogastric nervous system fails to alter the tanning response. In vivo stimulation of the nerve chord induces the terminal ganglion to release the hormone.

Journal of Insect Physiology, 1975
Abstract Bursicon activity first appears in the haemolymph of the cockroach, Leucophaea maderae , early in ecdysis as the old cuticle splits and separates over the thorax. Hormonal activity reaches high levels in the haemolymph before ecdysis is complete and remains so for about 1·5 hr, with a gradual decline and disappearance by 3 hr.

Bursicon, a Neuropeptide Hormone That Controls Cuticle Tanning and Beyond
2011Insects are encased in a semi-rigid exoskeleton, which provides protection, locomotion, and internal attachments sites for muscles and internal organs. However, it also limits insect’s growth. Insect must shed its old exoskeleton periodically (molting) in order to grow.

Effects of bursicon on cuticular properties in Locusta migratoria migratorioides
Journal of Insect Physiology, 1971Abstract Bursicon, the cuticular hardening and darkening hormone, is shown to be necessary as a hormone distinct from ecdysone if the insect is to ‘choose’ the time at which it ecdyses. Ligaturing experiments on ecdysing fourth and fifth instar Locusta migratoria migratorioides larvae show that bursicon is released from at least the terminal ...

Expression of bursicon-like activity during embryogenesis of the locust Schistocerca gregaria
Journal of Insect Physiology, 1992Abstract Bursicon is a neuropeptide that induces tanning of the cuticle in freshly moulted insects. This study shows for the first time that insect embryos also contain bursicon. In homogenates of Schistocerca gregaria embryos, bursicon can be detected at about 75% development with the aid of the ligated fly bioassay.

Bursicon, the cuticle sclerotizing hormone—comparison of its molecular mass in different insects
Journal of Insect Physiology, 1995Abstract We have shown in a recent study that bursicon, which induces the tanning of the cuticle in freshly molted insects, is a 30 kDa protein in the meal beetle Tenebrio molitor. We now show that bursicon in the insect species Calliphora erythrocephala, Periplaneta americana, Gryllus bimaculatus and Locusta migratoria is also a protein of about 30 ...
