Organic pest management can include the use of pheromone traps, the release of beneficial insects, the use of trap crops, and other organically approved techniques (see Rules related to pest control, next page).

Natural enemies are generally not active during the winter in the Northeast and, therefore, unless released again every year, they must have a suitable environment to spend the winter. Some parasitoids and pathogens overwinter in the bodies of their hosts (who may then have their own hibernation needs), but others can overwinter in crop residues, in other vegetation, or in the soil. A classic example is the hibernation of predatory mites in fruit orchards. The ground cover of these orchards provides shelter during the winter, shelter from pesticides used on fruit trees, and a source of pollen and alternative prey.
Adults of many predators and parasitoids may need or benefit from pollen, nectar, or honeydew (produced by aphids) during the summer. Many crop plants bloom evenly for a short time, so flowering plants may be needed along the edges of the field or within the field as supplementary sources of pollen and nectar. However, plant diversification in the field can also interfere with the efficiency of finding hosts, especially in the case of specialized parasitoids. Generalist predator populations can be stabilized thanks to the availability of pollen and alternative prey, but the effectiveness of predators still depends on whether they respond quickly enough, either by aggregation or multiplication, to outbreaks of the target pest.
Therefore, plant diversification or other methods to supplement the nutrition of natural enemies must be carried out with knowledge of the behavior and biology of the natural enemy and the pest. The seasonal inoculatory release of insect parasites and predators has been a highly successful strategy for biological control in greenhouses in Europe. Producers adopted this strategy because of the prevalence of insecticide resistance in many greenhouse pests and the increased costs of chemical control. The program was originally created around the use of the parasitoid Encarsia formosa against the whitefly in the greenhouse and the predatory mite Phytoseiulus persimilis against the two-spotted spider mite.
Over the years, additional natural enemies have been added to control other pests, such as thrips, leafminers, aphids, caterpillars and other species of whiteflies, as needed. The costs of using biological control are now much lower in Europe than those of chemical control of insect pests. Producers receive information on the details of the implementation of the program, new developments and new natural enemies through a network of extension advisors, specialized magazines and producer study groups. Two examples of the release of seasonal inoculants in the field are the use of the parasitic wasp Pediobius foveolatus against Mexican bean beetles, and the parasitic wasp Edovum puttleri against the Colorado potato beetle.
None of these parasitoids can survive the winter in the Northeastern United States. UU. However, methods have been developed to raise them in the laboratory and release them annually, and they multiply in the field and kill their hosts during the season. Foveolatus is commercially available, and E.
The New Jersey Department of Agriculture is raising and releasing Puttleri for integrated eggplant management. The impact of pesticides on natural enemies can be reduced by carefully programming and placing applications to minimize contact between the beneficial organism and the pesticide. Conversely, when a non-toxic method is found to control a key pest, reducing the use of pesticides and increasing the survival of natural enemies often reduce the number and damage of secondary pest species that were previously important. The brochure includes a discussion of the impact of organic mulches on soil quality and fertility, weed control, yields and waste production, and the profitability of small and medium-sized vegetable farms.
These two approaches are fundamentally different from all other approaches to biological control because they do not aim to establish a population of natural enemies that multiplies to a level where it achieves a long-term balance with the population of their hosts or prey. However, many integrated pest management programs have not been able to go beyond the first stage of developing sampling methods and economic thresholds for the application of pesticides. Therefore, the accurate identification of host and parasitoid species is of vital importance for the use of parasitoids for biological control. The mass release of natural enemy insects and mites in the field is still quite expensive, due to the costs of mass breeding, storage and transportation of living organisms in the necessary quantities.
A series of PowerPoint presentations developed for agriculture professionals on the principles of organic agriculture, soil quality in buildings, and the management of weeds, pests and diseases. Biological control is the use of living organisms to suppress pest populations, making them less harmful than they would otherwise be. FARMDATA is an online system for tracking and reporting agricultural production data, especially for producers of organic vegetables. Insects, which were previously of little economic importance, often become harmful pests when freed from the control of their natural enemies.
One of the many examples of a pest controlled by the successful introduction of new natural enemies is the alfalfa weevil. An example of an established population of a pathogenic insect that has successfully controlled its host is the fungus Entomophaga maimaiga, a pathogen of the gypsy moth. .
