Another alternative is to more than restore the natural balance that large scale commercial industrialized agriculture has destroyed thus requiring pesticides. Although I live in Brazil, first time I heard of Brazilian company doing this was a few hours ago on CNN international's program: The real Brazil. It cover many things (3.8million cars made in 2012, Embraer's new 23 ton cargo plane cheaper and better etc. than Lockheed's, 800 new buses for Rio, etc. with 3 billion dollar being spent just to be ready for both the world football cup (soccer) in June 2014 and Olympics in 2016, but what interested me (and I hope readers here) was small company call BUG. (
www.bugbrazil.com.br) So small they don't yet have English version of the web page, which has lots of photos and information. Thus I will make a reasonable but free stab at translating one small part of one sub-page below the original text, which is:
"Todas as espécies de plantas e animais têm inimigos naturais (parasitóides, predadores e patógenos) atacando seus vários estágios de vida. O equilíbrio inicial da natureza foi quebrado pelo homem com a implantação do sistema agrícola atualmente utilizado.
Atualmente, na busca da restituição de tal equilíbrio, o controle biológico assume grande importância, pois dentre as etapas de um programa de Manejo de Pragas ele ocupa uma posição bastante importante, sendo uma das medidas utilizadas para manter as pragas abaixo do nível de dano econômico, ao lado de métodos de controle físico, comportamental, de resistência de plantas a insetos, genético, entre outros, levando em conta critérios econômicos, ecológicos e sociais. "
All species of plants and animals have natural enemies (...) attacking them at various stages of their lives. The natural equilibrium that originally existed was destroyed by man introducing modern agriculture.
Thus it is very important to seek to restore an equilibrium via biological control ... to keep the level of economic damage low ... along with more conventional means ... taking into consideration economic, ecological & social factors. (End of my free translation)
That understates their hopes - they hope to nearly eliminated the need for pesticides. They have developed mean to mass produce very tiny wasps, and other GM organism that attack specific organism that damage specific crops, (soy and sugar cane are now using) and hopefully not the bees, but they don't speak of their approach as a possible "cure" for CCD.
