Now that's what I call Music

In a new paper published in Pest Management Science, CTBCC student Ben Muller, with supervisor Lin Schwarzkopf, demonstrate how choosing the best sounding male cane toads can reap benefits by trapping egg carrying females.

Ben  placed cane toad ‘audio traps’ with differing characteristics at various sites in the Townsville region, and was particularly interested in attracting reproducing females which can lay up to 20,000 eggs at a time.

Male cane toads did not appear to care what variation of volume, frequency and pulse rate were used, but female toads were much choosier.

“We found we could manipulate the proportion of females, and reproductive females, that we trapped by changing the calls used as lures.” Ben explains.

The scientists found that approximately 91% of the females trapped using a loud, low frequency tone with a high pulse rate were reproductive.

The research will be used by Animal Control Technologies Australia to help create a commercial trap.
