2 If You Do Not Know First Lego League The goals of this presentation are: To identify a problem in an interaction between a human and an animal. To propose a solution to this problem, which can be new or can improve an already existing one. 2

3 Our Problem : Mosquitoes Mosquitoes can spread dangerous diseases, such as Dengue, Chikungunya and Zika. Females' bites cause itches. 3

4 Mosquito Borne Diseases World Health Organization Mosquito-borne diseases Mosquitoes cause millions of deaths every year Mosquitoes are one of the deadliest animals in the world. Their ability to carry and spread disease to humans causes millions of deaths every year. In 2015 malaria alone caused deaths. The worldwide incidence of dengue has risen 30-fold in the past 30 years, and more countries are reporting their first outbreaks of the disease. Zika, dengue, chikungunya, and yellow fever are all transmitted to humans by the Aedes aegypti mosquito. More than half of the world s population live in areas where this mosquito species is present. Sustained mosquito control efforts are important to prevent outbreaks from these diseases. 4

5 The Diseases 5

6 'Zika Mosquito' Tiger Mosquito In France 6

7 The Mosquitoes' Life Cycle EID : Etablissement Interdépartemental pour la Demoustication The EID is the official mosquito control expert in France The larva lives in water and then metamorphoses and lives in the air. The adult female bites to lay eggs. It spreads diseases by biting. 7

8 Mosquito Control Mosquito control is mainly chemical using insecticides or by removing stagnant water. Some other methods include: - ultra sound repellents (not really effective) - natural repellents (Lemongrass,citronella...) - mosquito nets, clothes 8

9 Mosquito Control Each stage of the mosquito's life corresponds to a dedicated way of controlling its population. There is no ''miracle solution''. We decided to work on a natural way : ''predation'' also known as ''biological control''. 9

10 Mosquito Predators bats birds spiders batrachians dragonflies (larvae/naiads and adults) fish (they eat mosquito larvae) 10

11 Our Solution : Dragonflies Dragonflies are natural predators of mosquitoes. We thought that we could use them. Furthermore, in certain regions of France dragonflies are becoming endangered. Dragonfly eating a mosquito 11

12 Dragonflies Are Endangered In France A French Government sponsored National Monitoring And Action Plan is still in effect. 12

13 Dragonflies' Disappearance Dragonflies need humid zones Man is often at the origin of these zones and they are not taken care of nowadays Drying up marshy or swamp areas on purpose. 13

14 Dragonflies Are Endangered In France The French Red Data List 14

15 Dragonflies Are Endangered In France : Red Data List 15

16 Journal Le Monde March 2016 Out of 89 dragonfly species, around twenty are endangered and two are already extinct. 16

17 Raising Dragonflies In Class Students could discover dragonflies in class, and, using a kit, raise them to make scientific observations. Each year, schools would set them free to : Control the mosquito population Repopulate / help increase the populations of endangered dragonflies 17

18 Recommandations of the French Department For Education Raising insects in class is encouraged by the French 'Ministère de l'education Nationale' to introduce Scientific Observations 18

19 Educationnal Ponds (mares pédagogiques) Some Educationnal Ponds Projects are already implemented (Académie = administrative Zone, 5 total in France) Strasbourg Zone publishes a guide 19

20 How To Make An Educationnal Pond A real life example in Rouen (in a Secondary School UK system) specific advice for Odonata Partly sunny Mix deep and shallow areas List of recommanded plants Mix steep and slow slopes 20

21 Raising Dragonflies At Home At home, children could also raise Dragonflies by buying kits that include a voucher to get the larvae by mail, exactly like what already exists for Ladybirds and Butterflies. 21

22 Buying Larvae Larvae are already available for sale from various companies for other types of insects, same could be done for dragonflies. 22

23 Our Solution's Limits The correct dragonfly species must be sent to the right place (per country, we could use the postal code) Releasing too many dragonflies would create the opposite problem as they would predate on other species (tadpoles for example). 23

24 Our Solution's Advantages It will reduce the mosquito population. The solution we are proposing is not very expensive. It will help repopulate some some species of dragonflies. 24

25 th February, Interwiew We met Mr. Martin JEANMOUGIN entomologist at Muséum National d'histoire Naturelle in Paris (equivalent of the National History Museum in London) He is a specialist of Animal Conservation i.e. how to best help preserve species He gave us a lot of interesting advice and comments on our project. 25

26 Interview : How To Make It Happen It would be a lot easier to send dragonfly eggs than larvae, as larvae are more fragile. It is possible to use educational ponds: even a small one is sufficient. There are even dragonflies in Paris, they only need water. The larvae can be fed with daphnae or isopods 26

27 Interview : Limits It would be interesting to collect measures on the impact of the project on mosquito control. Most of the mosquito population is made of larvae, the longest part of the dragonflies' life is also spent as a larvae(naiad). The pond should be priviledged rather than the aquarium, even if using an aquarium is possible, it is often used by non-profit organizations for example. 27

28 Interview : Limits The extinction of certain species is linked to their particular and hard to reproduce habitats. For example, certain species need specific plants and/or a stream (and not stagnant water). This is clearly beyond an educational pond, and would need, for exemple an action on a National Park. 28

29 Interview : A ''Real'' Project It cannot have a negative impact on dragonfly conservation, and will only help these magnificent insects. In France, the reverse study is currently made to measure the effect of bacterial mosquito control on dragonfly population. Our idea creates a bond between society (school,children) and nature. For example it could be applied to the French project ''vigie-nature-école'' which means ''nature29 school-vigilance''.

30 ''Vigie Nature Ecole'' This program is made by the ''Muséum National d'histoire Naturelle'' and proposes experiments from 1st to 13th year (UK system). 30

31 What About The UK? It could be just a question of time before 'Zika mosquito' also invades the UK 31

32 What About The UK? Dragonflies are also endangered 32

33 Red Data List in UK 33

34 Raising Insects In UK Schools We could not find any official information from DfE about raising insects in class. The Royal Borough of Kensington & Chelsea publishes a 35 pages Teacher's guide to build Wildlife Gardens 34

35 To Sum Up Mosquitoes spread dangerous diseases and are responsible for thousands of death per year,'zika Mosquito'(a.k.a Tiger Mosquito) is invading France, it carries some of these diseases. Dragonflies are some of mosquitoes' natural predators, plus, in some regions of France they are in the Red Data List. We are proposing to raise dragonflies in class and at home. 35
