June 4: National Geographic: The Perfect Swarm (ATV World 10-11pm)

From Australia and West Africa to Cyprus, Israel and Egypt, giant locust swarms have been big news in the past month. Devouring everything in their path, they damage livelihoods, devastate entire regions and challenge authorities in how to deal with them. This show takes a look at the impact of locusts in West Africa this year and, using scientific research, tries to find out if their disappearance in North America in the last century could hold the key to stopping them today.

June 5: Timeblazers (ATV World 5.30-6pm)

What was it like building the great pyramids of Egypt? Where did people go to the bathroom in ancient Rome? What was it like to be a kid working on Columbus' ship as it set sail for the new world? These are the kind of nitty-gritty questions about history that children love to ask - and Timeblazers loves to answer.

Get to know the past by taking a trip through history. Alex always thought he was an ordinary kid - until Sam and Jen appeared. Now these two mysterious friends take him back in time to show him what life in the past was really like.

The only problem is, things always go wrong and lead to the craziest comic situations. Watch Sam stumble through a tour of duty as a member of Columbus's sailing crew in 1492. Or witness Jen becoming a high priestess in the lost Mayan civilization - given the task of sacrificing Sam to the Gods! You'll realise that for our heroes, each step back in time means a comic adventure that knows

no limits.

June 8: Built for the Kill (IV) (TVB Pearl 9.30-10.35pm)

Cats can be graceful and lethal hunters.

They are able to hunt down their victims in different environments, from dense rainforests to dry African savannas.

They have a large number of tools to execute the perfect kill.

Lions hunt together, while the leopard is a solitary stalker which takes its prey by surprise.

A jaguar's jaw has immense crushing power while the cheetah is built to kill at top speed. Lone hunters or team players, cats are highly specialised, and have their own mode of attack.
