In crustaceans the gonad function and development are under the control of the neuroendocrine axes and of a complex network of interrelationships between target tissues and nervous system. More than 65 years ago Panouse reported that eyestalk ablated shrimps showed an evident increase of gonado-somatic index, the ovaries reaching a weight about 13 times bigger compared to the controls. The hormones involved in the current scenario of endocrine control of reproduction are: 1) the family of eyestalk neuropeptides that includes the crustacean hyperglycaemic hormone (CHH), the moult inhibiting hormone (MIH), the mandibular organ inhibiting hormone (MOIH) and the gonad (or vitellogenesis) inhibiting hormone (GIH or VIH); 2) the biogenic amines (serotonine and dopamine); 3) the sesquiterpene methyl farnesoate. The pleiotropic effects of the different isoforms of CHHs in decapods play a central role in the reproductive physiology.
Lab current research
Production of synthetic cHH's isoforms to understand their roles in crustacean physiology.

Toxicity of insecticides at sub-lethal concentration to non-target generalist carabid predators are quantified by toxicity test, total/differential haemocyte counts and morphometric analyses.
Lab current research
The understanding of various chemicals long-term sub-lethal effects on carabids.
