The melanization of the Cabbage White pupae varies in response to light conditions. As abdomina, which are isolated by a ligature, become strongly melanized, the control evidently works in the way of gradual inhibition.The melanine patches of light pupae are not paler than those of dark pupae, but
The peptidome of the central nervous system of adult cabbage root fly, Delia radicum (L) was investigated using matrix assisted laser desorption ionization time of flight mass spectrometry (MALDI-TOF MS). Over twenty neuropeptides were identified from three different tissue sources, the combined
The circadian variation of pheromone production in the turnip moth, Agrotis segetum, was characterized by quantifying (Z)-7-dodecenyl acetate (Z7-12:OAc), the most abundant pheromone component produced by female turnip moth, at different times of day. Under 17:7 h light-dark cycle (LD), the peak of
In the female turnip moth, Agrotis segetum, a pheromone biosynthesis activating neuropeptide (PBAN) stimulates sex pheromone biosynthesis which exhibits a daily rhythm. Here we show data supporting a circadian rhythm in PBAN release from the corpora cardiaca, which we propose regulates the
A polyclonal antibody raised against locustamyoinhibin (Lom-MIH), a myoinhibiting neuropeptide of the locust Locusta migratoria, was used to search for locustamyoinhibin-like immunoreactivity in the central nervous system of the gray fleshfly, Neobellieria bullata, the Colorado potato beetle,
Migration of neurons over long distances occurs during the development of the adult central nervous system of the sphinx moth Manduca sexta, and the turnip moth Agrotis segetum. From each of the suboesophageal and three thoracic ganglia, bilaterally-paired clusters of immature neurons and associated
