Beneficial Nematodes - For Pest Insects
Beneficial nematodes seek out and kill all stages of harmful soil-dwelling insects. They can be used to control a broad range of soil-inhabiting insects and above-ground insects in their soil-inhabiting stage of life. More than 200 species of insect pests from 100 insect families are susceptible to these insect predators.
They are a natural and effective alternative to chemical pesticides, and have no detrimental affect on non-target species such as ladybugs, earth worms and other helpful garden insects.Finally, there is no evidence that parasitic nematodes or their symbiotic bacteria can develop in vertebrates. This makes nematode use for insect pest control safe and environmentally friendly. The United States Environmental Protection Agency (EPA) has ruled that nematodes are exempt from registration because they occur naturally and require no genetic modification by man.
Beneficial nematodes can be applied anytime during the year when soil-dwelling insects are present and soil tempertures are above 45-F during the day. Beneficial nematodes seek out and kill over 200 pest insects in the soil. They are a natural effective alternative to chemical pesticides. Beneficial nematodes are formulated and applied as infective juveniles, the environmentally tolerant free living stage that attacks the insect. Ther are several species and strains that are specialized for particular host insects. It is important to choose the right species for the job. Please review these nematode types for your selection. Steinernema carpocapsae, and Feltiae uses an "ambush" strategy as they wait for an insect host to move by, and therefore works well against pests that are moving around the soil surface. The Heterorhabditids bacteriophora do well against soil pests that are not as mobile because these nematodes are "cruisers", they actively search for hosts deeper in the soil.
