Biological control of Delia sp. in cole crops with rove beetles, Aleochara sp. (Part 2)

The objective of this study was to examine the use of rove beetles, Aleochara spp., for the biological control of root maggots, Delia spp. in organic cole crops. We were interested in manipulating Aleochara numbers by either conservation strategies or by augmentative releases of mass-reared Aleochara bilineata. 

A grower-managed biorational program for artichoke pests (BIORAPP) on the north central California coast

A native egg parasite, Trichogramma thalense, was mass-reared in the laboratory and released a maximum of thirteen times against the eggs of the artichoke plume moth (Platyptilia carduidactyla) in three 5-acre biointensive artichoke production fields on the northern Santa Cruz/San Mateo County coast in 1998 and again in 1999-2000.

Managing Natural Habitat Can Aid in Organic Pest Control

Summary

Determing habitat requirements for natural enemies of farm pests

Coordinator: Rebecca Chaplin-Kramer, University of California, Berkeley

Maintaining a healthy population of beneficial insects that serve as natural enemies to crop pests is an important component of pest management for organic farmers. To do so, we must understand the habitat requirements of these insects.
