Welcome to the Orchard Research Webpage.

Current research concerns investigations into aminergic and peptidergic neurons in insects and other invertebrates, with a view to elucidating the properties underlying integration and regulation. Specific areas of study include electrical recording and intracellular staining of identified peptidergic and aminergic neurons; identification of neuroactive substances and their receptors using molecular biology, HPLC, RIA and immunohistochemistry; pharmacological properties of receptors; involvement of second messengers in mediating target responses; cloning of peptide and receptor genes; and the use of this information in the biorational design of pesticides. Systems of particular interest include those associated with FMRFamide, diuretic hormone, proctolin, octopamine, dopamine and serotonin.

You are invited to watch this Mediasite presentation: RCI 619M - The Kiss of Death: Rhodnius as a Vector of Chagas' Disease

Description: Rhodnius prolixus, the kissing bug, is a blood-feeding insect found in Central and South America.  Rhodnius is one of the vectors for the parasite Trypanosoma cruzi that causes Chagas' disease in humans.  This talk will examine the physiological and endocrinological aspects of Rhodnius that leads to the transmission of this disease, using data from its recently sequenced genome.
