A study addressing commercial beneficial insect habitats found some seed mixes had variable species composition, reduced germination, and when planted according to supplier recommendations were eliminated by weed competition. A small proportion of insects attracted to habitat plants were natural enemies useful in crop insect management. A number of plant feeding insects were harbored by habitat, and night-flying pest moths were fed by some habitats. A commercial habitat planted around organic tomatoes did not affect parasitism, predation, or pest insect numbers. Habitat plantings did attract parasitic insects, but the flowers themselves did not appear to be responsible for this attraction.
1. To evaluate commercially available beneficial insect seed mixtures for purity, composition, and germination rates.
2. To monitor the communities of insects, both beneficial and otherwise, attracted to commonly planted cut flowers and cover crops on organic farms
3. Based on currently available literature, construct and evaluate a simple beneficial insect habitat designed to attract and build populations of Trichogramma wasps and Cotesia congregata, well-known parasitoids of eggs and larvae, respectively, of tomato fruitworms and hornworms.
