Patrick De Clercq
Ghent University, Belgium

     I am a professor of entomology and biological control in the Department of Crop Protection at Ghent University, Belgium. Part of my research focuses on the biology, mass-rearing and biocontrol potential of predatory pentatomids (Asopinae).

Current Projects:

1) Life history of predatory pentatomids (e.g., Podisus spp., Picromerus bidens)

2) Nutritional physiology of predatory pentatomids (digestive enzymes, gut bacterial flora)

3) Development of rearing methods and artificial diets for predatory heteropterans, including Asopinae

4) Potential of Podisus maculiventris and Picromerus bidens for augmentative biological control of lepidopteran and coleopteran pests

5) Integrated control of the southern green stinkbug Nezara viridula
