Bioassays for testing insecticides against arthropod pests

We perform various bioassay tests for various companies and agencies to quantify the ability of new insecticidal formulations to kill and repel a wide array of arthropod pest species. Some of the species we utilize in our testing includes, but is not limited too: house flies, cockroaches, ticks, bed bugs, mosquitoes, fleas, crickets, corn rootworms, corn borers, cutworms, aphids, and spider mites. The fees for service, as well as the types of testing to be performed, are negotiated via a contract basis. Read more about Bioassays for testing insecticides against arthropod pests

Mechanisms of action of natural insecticides and acaricides; expression of octopamine and tyramine receptors in mammalian cell lines

Octopamine and tyramine are essential biogenic amines that have been implicated in numerous physiological systems in arthropod species, such as reproduction, the nervous system, and  learning-and-memory, to name a few. We have successfully created two stably-transfected Chinese Hamster Ovary cell lines (CHO) with a functional octopamine receptor from Periplaneta americana, the American cockroach, and a functional tyramine receptor from Rhipicephalus microplus, the southern cattle tick.

Natural Terpenoid repellents with activity against mosquitoes, flies, cockroaches, ticks, and bed bugs

It is well established that insects and plants have shared a long evolutionary history with one another. Due to this evolutionary “arms race,” plants have developed some truly fascinating ways to deter insects from feeding upon them, such as production of various terpenoid compounds that repel or kill insect pests. Our lab is interested in isolating plant-derived compounds that may act as natural repellents.
