from Molecular…

Research at the Insect Biocontrol Laboratory runs the gamut from examining DNA sequences and individual proteins to complex ecosystems such as those found in row crops, coffee plantations and forests.

Within these broader categories of research, specific studies focus on diverse topics. In the molecular arena, some of our scientists are performing DNA sequence analyses on pathogens that infect insects, such as viruses and fungi.  These are not obscure scientific investigations. Understanding the genetics of these organisms can help us identify genes that make them successful biological control agents. Additionally, some of this work can result in tools for manipulating the genetics of other organisms.

Certain studies are directed at determining the toxic components of bacteria that are pathogenic to insects. Once identified, we can look for bacterial strains that make more of the material and make sure it is safe for non-target organisms.  More effective pest control may be obtained by our research on discovery and modification of plants genes that respond to pest insect attack.  

We are also developing new tools for producing insect pathogens, such as establishing insect cell cultures for production and study of insect-pathogenic viruses.

through Insects…

Beyond the microscopic and submicroscopic, our studies also include research on the effects of microorganisms on insects as well as identifying and researching factors such as hormones and regulators of insect development.  Much of this research focuses on specific pest insects such as those pictured here. 

 Scientists in the Insect Biocontrol Laboratory are also studying insects and other arthropods that prey on or parasitize key pest insects.  As part of this work, we are developing molecular methods for the detection of predation and parasitism in the field.  Examples include the parasitic wasp and fly pictured here and predators such as this beetle.

to Ecosystems

Our ultimate goal in the Insect Biocontrol Laboratory is to create new tools for management of pest insects in a variety of ecosystems.

The Insect Biocontrol Laboratory has had a long-term effort in the management of the gypsy moth in urban settings and a close collaboration with colleagues in the Forest Service for control of the pest on a wider scale.  The laboratory is currently intimately involved in the national Slow the Spread of the Gypsy Moth Program designed to reduce the rate of gypsy moth advancement into uninfested areas.

The Colorado potato beetle is also a major focus in the laboratory.  In addition to pursuing biocontrol agents, new crop management practices are also being researched, such as mulching to improve effectiveness of natural enemies against this pest.

While coffee is a relatively minor agricultural crop in the U.S., it is the second most widely traded commodity in the world and has a major financial impact on the U.S. economy.  The coffee berry borer has caused substantial production losses as it has spread to new areas, and the IBL is working to develop new management practices utilizing biological methods.
