What is it about?

After A. ipsilon, we considered further study of the neuroendocrine-pheromone system regulations by an analysis of juvenile hormone (JH) interactions not only with a brain neurhormone (PBAN), but also with bursa and mating factors in Tortricid moths.

Why is it important?

The result is important for the agricultural industry since noctuid and tortricid species are known serious threats (insect pests) on many various crops not only in France and Canada, but all over the world. The interplay between JH and PBAN that we describe in migrant species of moths such as Agrotis (continental spread) and Choristoneura (can disperse across distances ranging from 20 to 450 km) is a crucial link between external variations and the command either take off (long distance flight) or the onset of mating activities and reproduction. Importance is also for comparative physiology and insect physiology: Agrotis JH and pheromone=activation, Choristoneura: JH and pheromone=inhibition.

Perspectives

New control methods for black cutworms, spruce budworms and oblique banded leafrollers (apple orchards). Understand more complex neuroendocrine systems as those described between hypophysis and hypothalamus Perhaps some medical impacts in human physiology, i.e. regulation of stress, digestion, immune system, mood and emotions, and even perhaps <<human pheromone or sexual attractant>>
