Dr. Jang has 33 years of research experience in the area of entomology, primarily in the areas of insect physiology/biochemistry, postharvest entomology, insect chemical ecology and areawide management. His early research was on hydromineral regulation in salt tolerant insects, followed by his Ph.D. research on hormonal control of cuticular melanization in moths. Postdoctoral research centered on chitin synthesis inhibition in cultured insect cell lines and anti-juvenile hormone mode of action in insects. With ARS Dr Jang has worked on postharvest disinfestation and chemical ecology of tephritid fruit flies and other pests. Dr. Jang has authored or co-authored over 165 scientific papers, conference proceedings and book chapters. He has been invited to speak at over 60 regional, national and international meetings and conferences on his research and has hosted three international workshops on insect chemoreception and the Fifth Asia-Pacific Conference on Chemical Ecology. Dr. Jang's expertise has been further recognized by his appointment to chair numerous international, federal and state scientific advisory panels, and request for consultations worldwide in the areas of tephritid fruit flies and other invasive pests. He is frequently asked by Joint FAO/IAEA Pest Control Section to participate and provide advice on program-related activities. Dr Jang is currently President of the Asia-Pacific Association of Chemical Ecologists and research Leader of the unit.
New and improved semiochemicals for fruit flies
Use of fruit fly attractants form the core of detection, delimitation, control and eradication of these invasive quarantine pests throughout the world. Dr Jang and his team has developed several new semiochemicals lures that are commercially used to trap the Mediterranean, oriental and melon fruit fly. These lures are also effective against some other invasive pests. Dr Jang has also worked on identification moth pheromones for use in detection and delimitation of pest moth species.
Quarantine heat treatments
Dr Jang developed thermal death kinetics to describe effects of heat on immature stages of fruit flies. This has lead to heat treatments for use against fruit flies attacking mango and lychee. Use of vapor heat for disinfestation of keitt mango is now approved by Japan.
Systems approaches for risk mitigation
Dr Jang and team developed the conceptual framework for what is known as the systems approach to quarantine security. The systems approach is an alternative to single disinfestation treatments and rely on sequential mitigation procedure that cumulatively reduce risk of insects in consignments to acceptable levels of risk. The systems approach concept has been codified in FOA / IPPC international standards acceptable worldwide to member nations
Physiological control of behavior
Dr Jang identified key physiological processes associated with mating in fruit flies that control and/or modulate specific olfactory behaviors in these flies. Factors associated with male accessory glands can affect behavior and mating refractory periods in insects
