Heterorhabditis bacteriophora is nematode against the larvae of weevils such as the taxus weevil. The larvae are about 1.0 to 1.5 mm. long in their third stage. The other stages will develop inside the host.
Life cycle and relative effectiveness
Nematodes actively search towards the larvae of the taxus weevil and will enter them. The nematodes feed themselves on the content of the larvae and separate certain bacteria from their intestinal. These bacteria will ensure that the host tissue is covered into a substance which is easy to be incorporated by the nematodes. Infected larvae are pink, red and brown colored.
Application and dose
The moisture content of the soil must be high, for a proper effect of heterorhabditis. The soil temperature must be in between 10ºC and 25ºC. The material must dissolve completely in a bucket or spray tank with 5 – 10 litre water included. Important: stir the suspension well and remove filters before spraying (nozzle of minimum 500 micron)
Storage and handling
Heterorhabditis bacteriophora supplied in boxes, containing 50 or 500 million larvae (third larval stage). Keep the boxes horizontally, in darkness, at a temperature between 2°C – 6°C. Maximum storage time of three months.
