THE ORGANISM
- heterorhabditis bacteriophora
1. BRAINSTORMING
QUESTIONS
- Which temperatures do nematodes need?
- Nematodes need temperatures at 12°C and higher to be in an active state. If temperatures are temporarily decreasing they get into an inaktiv mode.
- What exactly are they eating?
- How do they live?
- How long do they live?
- What length are they able to become?
- Do they make any noise?
- Do the react to vibration?
- Do they react to acoustic noise?
- When put in one place, how are they spreading?
- Do they leave tunnel marks?
- Do they leave any visible marks?
- Are there indicators for the toxin they are using to eat larva?
- What senses do they have?
RESEARCH
- "Results showed that modified Wouts medium and nutrient agar medium-I multiplied significantly higher numbers of 39.02 - 39.14 lakh IJs of H.. bacteriophora strain KKMH1 per 250 ml flask." [1]
- "These nematodes are characterized by their ability to carry specific pathogenic bacteria, Photorhabdus with Heterorhabditidae [...]which are released into the insect haemocoel after penetration of the insect hosts by the infective stage of the nematodes. Most biocontrol agents require days or weeks to kill the pest, but entomopathogenic nematodes with their symbiotic bacteria kill insects in 24-48 hr."[2]
PROJECT IDEAS
- Photographic
- Scan a "nematode world" (Colours, tracks, frozen postitions,..)
- Scan a "nematode world" (Colours, tracks, frozen postitions,..)
- Acoustic
- make sound out of nematodes movements
