The ‘super’ house-mouse and the malaria carrying mosquito have made the news recently. They are just two of a growing number of pest species that are becoming less and less effected by the chemicals we use to control them. In Europe, this is quite literally a growing problem; agricultural yields are threatened by pest resistance, and regulations lack short-term solutions. The ‘super mouse’ is not a super hero, but its story may save us with the warning it carries.
Living in Europe, malaria and DDT are a distant worry. People often fail to realise how deadly the disease is and that pesticides are used as one of the most effective tools for destroying the carrier of malaria – the mosquito.
Pesticides are used to kill the bugs and diseases that destroy agricultural crops. These bugs and diseases are part of ‘biodiversity’, the variety that exists between life forms. Paradoxically agriculture needs biodiversity – relies on it in fact. Biodiversity pollinates plants, it purifies water, prevents soil erosion, it even helps control the climate through the sequestration of carbon dioxide. Without biodiversity there would be no agriculture, but left to the mercy of biological diversity, and the hard knocks rule of survival of the fittest (Darwin’s ‘natural selection’) we would struggle to feed ourselves – pests and plant diseases taking food from our mouths.
Everyone has heard of Malaria, a disease that is estimated to claim between one and three million lives every year. Young children account for 90% of the deaths, the majority of victims are in sub-Saharan Africa.
