How Steinernema carpocapsae nematodes will kill the fall armyworms?
When Steinernema carpocapsae nematodes are applied to the pasture fields, they will actively search for all the soil-dwelling larval and pupal stages of fall armyworms. After locating larva or pupa, nematodes will enter into their body cavity through the natural openings like anus, mouth and spiracles. In the body cavity, nematodes will release symbiotic bacteria (Xenorhabdus nematophila) in the blood where bacteria will multiply quickly, cause septicemia and kill both larva and pupa within 48 hours of infection. Thus the killing of both larvae and pupae completely stops the emergence of next generation of adult fall armyworms. Read More
Beneficial Steinernema carpocapsae nematodes have a potential to control tropical sod webworm, Herpetogramma phaeopteralis, one of the most damaging pests of turfgrass. Sod worms are lepidopterous insects that cause a serious damage to turfgrasses that are grown in the athletic fields, golf courses, home lawns and recreational parks. Adult moths do not cause any type of damage to turfgrass but their larval stages feed on turfgrass and reduce its aesthetic value. Read More
Three beneficial nematodes including Heterorhabditis bacteriophora, Steinernema carpocapsae and Steinernema feltiae have a potential to use as a biological control agents to manage populations of Queensland fruit fly, Bactrocera tryoni, which is one of the most economically important insect pest of many fruit crops.

Two beneficial entomopathogenic nematodes including Heterorhabditis bacteriophora (Fig.1) and Steinernema carpocapsae (Fig. 2) have showed a potential to control cucurbit flies, Dacus ciliatus (Kamali et al., 2013). These nematodes are considered as beneficial nematodes because they have been used as biological control agents to control insects that are damaging to crops and harmful to animals Read More
