Pre-mating behaviors and the growth and development of the ovaries are controlled by the juvenile hormone-III, which is produced in the corpus allata.
42.
Williams was the first to isolate juvenile hormone and ecdysone, and discovered cocoonase and cytochrome b5, as well as the " paper factor ".
43.
The regulation of the female sex pheromone production, calling behaviour and release is regulated directly and indirectly by the corpora allata and juvenile hormone.
44.
PTTH also stimulates the corpora allata, a retrocerebral organ, to produce juvenile hormone ( JH ), which prevents the development of adult characteristics during ecdysis.
45.
Juvenile hormone must be absent for a pupa to molt to an adult, so methoprene-treated larvae will be unable to successfully change from pupae to adults.
46.
The original description of the insect juvenile hormone by Carrol M . Williams in Nature in 1956 is from the Cecropia silkworm ( " Platysamia cecropia"
47.
Superworms are common in the reptile pet industry, not to be confused with giant mealworms, which are " Tenebrio molitor " larvae sprayed with juvenile hormone.
48.
This hormone is a juvenile hormone analogue, which affects hormonal balance and chitin in premature insects, which causes deformation and death during molting and pupation stages.
49.
In colonies of " Bombus terrestris ", the queen can control oogenesis and worker egg laying by regulating concentrations of juvenile hormone ( JH ) in workers.
50.
Commercial growers incorporate a juvenile hormone into the feeding process to keep the mealworm in the larval stage and achieve an abnormal length of 2 cm or greater.
