Steinernema feltiae

Exhibitline Sf biological control agent contains the insect pathogenic nematode, Steinernema feltiae, as infective juveniles. It helps control fungus gnat larvae and Western Flower thrips on ornamental plants.

Target Pests

• Fungus gnats
• Western flower thrips
• Onion thrips
• Echinothrips

Key Features

• Provides uo to 6 weeks of protection from fungus gnat larvae.
• Steinernema feltiae also attack thrips pupae in soil.
• Kills adults and larva of thrips.
• Also attacks leafminers in leaves.
• Simple and safe to use, feltiae occurs naturally in soils.
• Contact with dip/application solution is critical for efficacy.
• Increased efficacy on thrips adults and larva on foliage have been observed if crop stays wet longer.
• Best time of application in the evening just prior to sunset or on cloudy rainy day.

How It Works

• Harmless to the ornamental crops, humans, the environment and other beneficial insects, these nematodes actively seek out vine weevil larvae by swimming in the thin film of water on soil particles. They locate hosts by detecting carbon dioxide and other waste products. After locating pest larvae, nematodes invade through natural body openings and inject bacteria into the insect. Bacteria develop within the insect and it dies of septicemia.
• Under optimum conditions, the insect can die within 12-24 hours. Insect mortality will depend on the environmental temperature. The minimum soil temperature should be 12°C for nematodes to work most efficiently and the maximum soil temperature should be no more than 26°C.

Delivery System

• 50 million entomopathogenic Heterorhabditis bacteriophora nematodes in an inert carrier in sealed trays
