Heterohabditis bacteriophora

Beneficial Nematodes are microscopic, nonsegmented worms that occur naturally in soil all around the world. Once they are released, the nematodes seek out host insects and enter their prey through body openings, injecting them with lethal bacteria, then feeding on the resultant "goo".The nematodes reproduce and their offspring feed on the insect cadaver and emerge to seek out new hosts. The endo-toxin generally results in death of the host insect within 48 hours.

Nematodes are easy to use. They are shipped in a dry powdery clay or gel formulation that is easily mixed with water. The solution can be applied using a watering can; hose end, backpack, or pump sprayers; or through irrigation or misting systems. Always release early in the morning or late afternoon when temperatures are cooler and away from direct sunlight to avoid exposure to ultraviolet rays and the drying effects of the sun. It is good to pre-moisten the soil before application and to water the area where application was performed afterwards. Soil should be moist, but not saturated.

Generally, 1000 million H. bacteriophora (20 x 50 million) will effectively treat up to 5 acres broadcast. Nematodes can be stretched further if multiple releases are performed. May be combined with other beneficial nematode species. Release nematodes every 3-6 weeks or until infestation subsides.

Nematodes can be stored in a refrigerator (do not freeze!) for up to 2 weeks, but it is best to use them as soon as possible, because they are somewhat perishable. If they start to smell bad, they're on their way out.

The nematode enters the host and kills it within 24 to 48 hours. It then reproduces within the host, juveniles develop, emerge from empty host body and search for new hosts. This hunt and seek cycle provides long-term control.

Heterorhabditis bacteriophora

Among the most important entomopathogenic nematodes, H. bacteriophora possesses considerable versatility, attacking lepidopterous and coleopterous insect larvae among other insects. This cruiser species appears most useful against root weevils, particularly black vine weevil where it has provided consistently excellent results in containerized soil.

This nematode species is similar to Steinernema except that it can enter its prey directly through the body wall as well as through body openings. Considered by many to be more agressive.

A warm temperature nematode, H. bacteriophora shows reduced control when soil drops below 68°F (20°C).

Target Pests:
Weevils, Beetle grubs, Japanese beetle, Masked chaffers, May/June beetles, Black vine weevil, various white grubs, Banana weevil, Bill bug, Colorado Potato beetle, Cucumber beetle, Sweetpotato weevil, Asparagus beetle, Carrot weevil, Banana moth, Citrus root weevil group, Sugarcane stalk borer, Various tree and vine borers, Bagworms, Flea beetle, Fleas and over 200 other soil dwelling insect species.
