Natural Products for Control of Parasitic Honey Bee Mites

Objective Statement:

Objectives were: 1. to provide beekeepers with safe, effective, reliable and affordable alternatives to Apistan and Coumaphos for control of parasitic mites. Currently, these chemicals must be applied twice each year to ensure colony survival, and that is often insufficient. I will investigate alternative strategies that either reduce the use of synthetic pesticides by ½ or that eliminate them all together.

Using Pediobius foveolatus as a biological control agent for Mexican bean beetle in snap beans

Objectives

1) Test two options for reducing damage from Mexican bean beetle in the first year of release: a) Raise the release rate of wasps, and b) Apply one spray of a botanical insecticide to reduce the initial density of adult beetles, then release the wasps at the usual rate after the spray residue is gone and when remaining beetles are in the appropriate larval stage. 

Bat Houses for Integrated Pest Management-- Benefits for Bats and Organic Farmers: Phase I

The first objective of this study (Phase I) was to establish four bat houses (two pairs each of a proven nursery design) at 10 organic farms in California and Utah. Larger, experimental designs were to be installed at five of these sites for testing purposes. Data from the North American Bat House Research Project shows that pairs or groups of houses are more successful than single houses.

Control of the western tarnished plant bug, Lygus hesperus (Knight) in an organic strawberry production system using trap crops, mass-released parasitoids, and tractor-mounted vacuums

Strawberry growers on the Central Coast of California have long observed that the principal cosmetic pest of their crop, the western tarnished plant bug (WTPB) or lygus bug, Lygus hesperus (Knight) establishes populations in strawberry fields in mid-season in relation to the proximity and flowering status of weedy, broadleaved hosts in adjacent areas. WTPB is known to be hosted in winter and early spring by numerous wild hosts which serve as a bridge to the infestation of strawberry fields when strawberry host flowers and small green fruit become abundant.

Insect management and fruit thinning in commercial organic apple production systems in New York

PROJECT OBJECTIVES

1. Develop an integrated, sustainable arthropod management system that will allow the production and marketing of certified organic apples.

2. Develop alternative chemical fruit thinning approaches for use in certified organic apple orchards that will result in annual cropping and large fruit size.

3. Develop alternative weed control approaches for use in certified organic apple orchards that will result in similar tree growth, yield, fruit size and leaf nutrient levels as conventional herbicides.

Investigations into the Ecology of Microtheca ochroloma and control methods for organic farmers

Objectives The original objectives of the project were as follows: 1. To determine if beetles remain active into summer if crucifers are present under field conditions. 2. To determine if initial infestation of M. ochroloma arise from within the field from the soil subsurface or whether beetle enter the field from field edges after oversummering. 3. To determine whether intercropping crucifers protects them from YMLB by hiding them among non-host plants. 4. To determine if cutting crucifers makes them easier for the beetles to find, therefore increasing infestation. 

Integrating conservation of generalist predators and specialist parasitoids in Pacific Northwest organic vegetables

As outlined in our initial proposal our project objectives were as follows: 1) Evaluate in-field refuges for predator conservation and the control of root maggots (Delia spp.) and aphids. 2) Evaluate efficacy of floral plantings for conservation of root maggot and aphid parasitoids. 3) Transmit our findings to growers. 

Intercropping to Create Local Refugia for Natural Enemies of Arthropod Pests: Flowers and Birds in Organic Agroecosystems

Farmer surveys conducted during the first year of a multi-year research program investigating the diversity and utilization of North-central Florida farmlands by birds demonstrated a great interest by organic producers in the potential impact birds have on insect populations in their cropping systems (Jacobson at al. 2003). They expressed interest in management recommendations designed to enhance the presence and foraging activities of insectivorous birds on their farms. Therefore based upon this interest we developed the following objectives for this study:

Evaluation of Glandular-Haired, Potato Leafhopper Resistant Alfalfa for Organic Farming Systems

Objectives

The primary objective of this proposal was to determine the ability to produce organically grown alfalfa in areas with significant potato leaf hopper pressure and then to share this capability with organic growers. Specific experimental objectives were:

1. Determine if glandular-haired, PLH resistant alfalfa can be produced organically,

2. Determine if organically grown glandular-haired, PLH resistant alfalfa can reduce PLH density,
