Michael Crossland's research showed that the chemical in question is the poison that toads produce.īaited with toad poison caught tens of thousands of toad tadpoles within a fewĭays! Here, we have taken the top off a trap to show many trapped tadpoles inside, and many others looking for the entrances (the red funnels on either side) so they can join their friends. And the way the cannibals locate the eggs is by a special chemical that oozes out of the egg as it develops. In our field trials, eggs placed into a pond that already contains cane toad tadpoles have almost no chance of survival. The cannibal tadpoles not only get a meal, but they also eradicate the future competition. How does it work? Remarkably, cane toad tadpoles are cannibals - if they detect a newly-laid clutch of cane toad eggs in their pond, they race across and start killing and eating them. In one natural pond, weĬollected more than 40,000 toad tadpoles in less than a week. Thousands of toad tadpoles and almost nothing else. When we use this chemical as bait in a funnel-trap, we catch (like fishes and insects) aren’t attracted to this chemical, but toad tadpolesĪre incredibly good at detecting it, and they search for its source as soon as This makes it perfect to use as “bait” inĪ funnel-trap to catch toad tadpoles. Have discovered a chemical that is highly attractive to toad tadpoles but TEAM BUFO has found an exciting new weapon that can make a huge difference … we Make a big difference because there are no new toads being born, to replace the If we can do this, then removing adult toads can The only way around this problem is to stop Where you started – just as many cane toads as ever. That even if you catch and kill 99% of the adult toads in an area, the few thatĪre left can produce so many offspring, that before you know it you are back to Toads is that a single clutch can contain more than 30,000 eggs. The biggest obstacle to getting rid of cane
