:00:10. > :00:13.Hi guys, Ricky here with the big stories for you this Sunny Sunday.
:00:14. > :00:14.Coming up: The real life tiny dragons.
:00:15. > :00:32.First up, many have you will woken up early this morning to write cards
:00:33. > :00:34.or even make breakfast for your dad because it's Father's Day!
:00:35. > :00:37.So we want to know today what makes your Dad special
:00:38. > :00:40.to you and tell us what you have got planned to celebrate Dad's Day?
:00:41. > :00:48.And around half a billion cricket fans will tune in to watch India
:00:49. > :00:51.take on rivals Pakistan in the Champions Trophy Final this
:00:52. > :00:53.afternoon which is taking place at the Oval in London.
:00:54. > :00:55.Tickets for the game are mega hard to come by,
:00:56. > :01:01.but even people watching on TV are getting in the party mood.
:01:02. > :01:07.It's called an armyworm, and while it might look
:01:08. > :01:09.like something you'd see in your garden, they're a much more
:01:10. > :01:11.serious type of pest, as Jenny's been finding out.
:01:12. > :01:13.Called fall armyworms, but they aren't worms at all,
:01:14. > :01:17.Despite their size they have been causing massive problems
:01:18. > :01:21.They feed on a range of different crops, but in particular
:01:22. > :01:23.on maize and sweetcorn, this is a very important crop
:01:24. > :01:28.in Africa because many farmers rely on maize to feed their families
:01:29. > :01:31.and to crush the corn to make maize flour,
:01:32. > :01:36.They have come to Africa from the Americas, and their numbers
:01:37. > :01:38.are growing very fast, with females laying
:01:39. > :01:43.The pests started having an impact in West Africa
:01:44. > :01:46.at the end of last year, but since, they've spread.
:01:47. > :01:49.Scientists are warning that parts of southern Africa,
:01:50. > :01:53.already hit by drought, are now facing another food crisis.
:01:54. > :02:01.Well, the usual method of controlling any insect pest
:02:02. > :02:10.The downside is that they can also have a negative
:02:11. > :02:16.Not only do they kill the target pest insect,
:02:17. > :02:18.in this case the fall armyworm, but you may also kill beneficial
:02:19. > :02:22.insects like pollinators and predators who would normally
:02:23. > :02:27.Another idea is to use the diseases that the worms are harmed
:02:28. > :02:30.by and spray them onto the plants, getting rid of fall armyworms
:02:31. > :02:43.In some small farms farmers have been able to pick the army worms off
:02:44. > :02:46.In some small farms farmers have been able to pick the armyworms off
:02:47. > :02:48.crops with their hands, but with the number of armyworms
:02:49. > :02:51.continuing to grow, scientists will have to find a solution fast
:02:52. > :02:57.to stop these pests from spreading even further.
:02:58. > :03:02.Next, to Australia, where scientists are trying to save a unique animal
:03:03. > :03:07.There are worries the creatures are now endangered.
:03:08. > :03:11.Not far off the coast of Sydney in Australia is what's known
:03:12. > :03:18.People diving here will find strange and beautiful creatures living
:03:19. > :03:23.The locals call these guys weedies, otherwise known
:03:24. > :03:28.Native to the coast around Australia, they are related to sea
:03:29. > :03:33.horses and spend their time drifting in the water, blending
:03:34. > :03:39.The problem is these colourful creatures are becoming
:03:40. > :03:42.harder and harder to spot, and not just because
:03:43. > :03:46.This is the best site in Sydney so you can
:03:47. > :03:50.still see them here reliably, other sites, particularly
:03:51. > :03:53.on the north side of Sydney, where they used to be a common
:03:54. > :03:56.occurrence, now you are likely to find one and sometimes
:03:57. > :04:04.Marine biologists have come up with a clever plan to work out how
:04:05. > :04:08.They are asking divers to snap a picture of
:04:09. > :04:13.The researchers are then using a kind of facial recognition
:04:14. > :04:15.software to identify each fish's unique patterns.
:04:16. > :04:19.Every time they identify a new weedy they give it a name
:04:20. > :04:27.to help keep track of it, kind of like Facebook for weedies.
:04:28. > :04:30.It will tell us if it is David or Greg or Alicia because every
:04:31. > :04:33.single new sea dragon we have gets a name and then we can
:04:34. > :04:39.Weedy sea dragons are classified as near-threatened,
:04:40. > :04:42.but the scientists reckon this research could provide enough info
:04:43. > :04:47.to have them relisted as endangered, which is more serious.
:04:48. > :04:50.Scientists believe climate change could be a big part
:04:51. > :04:56.They say rising sea temperatures are killing the seaweed
:04:57. > :05:09.Once we lose them we will never get them back.
:05:10. > :05:12.They were here hundreds of thousands of years ago but with our impact,
:05:13. > :05:18.So if you find yourself diving in Australia,
:05:19. > :05:21.snap a picture to make sure there are plenty of little weedies
:05:22. > :05:26.Sorry for the small technical problem there.
:05:27. > :05:29.Next up, it's one of the most famous parts of any rugby match
:05:30. > :05:31.against New Zealand, the traditional Haka war dance.
:05:32. > :05:34.Usually it's scary enough facing 15 rugby players doing it,
:05:35. > :05:36.but imagine seeing more than 7,000 people take up the challenge!
:05:37. > :05:39.This is a new world record, which was achieved before
:05:40. > :05:43.the British and Irish Lions took on the Maori All-Blacks yesterday.
:05:44. > :05:48.They had to perform for five minutes to break the record.
:05:49. > :05:51.It wasn't just locals taking part though, a number of Lions'
:05:52. > :05:56.That's all from me, Newsround's back at 2.15pm.
