  • Peregrinus maidis
  • The insect, Peregrinus maidis, is proposed to have been blown great distances and is known to wipe out entire crops (Brewbaker 1979). It is only deadly in places where maize is cultivated all year long. The spreading of the maize mosaic virus (MMV) can be noted by monumental date inscriptions from southern lowlands Mayan centres (Brewbaker 1979). The last inscribed date at the site known as Palenque comes in the year 799 while on the other hand; the final date at Piedras Negras comes in the year 795 A.D. (Brewbaker 1979).
  • In the humidity of tropical areas, the cultivation of maize is never free from pests and crop diseases. Pests include borers, worms of all natures and the weevils who harm stored grains (Brewbaker 1979). On the other hand, viruses and diseases that negatively affect the harvest include rusts, blights, stalk and ear rots and downy mildews (Brewbaker 1979).

  • Most recently, scientists have turned their work towards the possibility of disease. The climate was humid and would have supported a host of parasitic activity. As the Mayan civilization grew and spread, disturbances would have occurred which could have placed the people in contact with parasites that would promote disease and death. If this were the case no member of the Mayans would have been spared. As with many diseases that attacked the human body, death can be a slow process dependent upon the strength and health of the individual attacked.

  • The causes for the Maya's decline are numerous, but one of the central causes is that the demands they placed upon their environment grew beyond the capacity of the land. At it's peak, there were about 15 million people occupying the Mayan world. Over-population of Mayan metropolises are suspected to have gone beyond levels that the Mayan political and social networks were able to support, resulting in social unrest and revolution. Frequent skirmishes by warring clans, such as the Toltec invasion of Chichen Itza, are suspected to have forced the Mayan populace to flee their cities. Recent studies have discovered evidenc
  • of severe droughts, deforestation, and a decline in large game animals that began around 800 A.D., coinciding with a sharp drop in new construction. Human bones found from this time show signs of severe malnutrition, which would have been a driving factor behind raids. While Maya civilization did go through a brief renaissance after this period, ongoing environmental constraints played a large role in their eventual decline.

  • European Diseases - The Spaniards carried diseases that killed the Aztecs. As the Aztecs and the Spaniards fought in Tenochtitlan, the small pox epidemic began to kill the people. The Aztecs had no immunities to any of the European diseases. In 1518 there were about 25 million Mexicans. Fifty years later, less than 3 million Native Americans survived.

      Wow that is interesting, I can't believe that small pox killed the Aztec's and so many of them. That also reminds me of Spanish wars the Americans have been in and many got killed from small pox. Looks like Spanish could have trouble in years of big small pox breakdowns.

  • the development of chronic warfare caused a breakdown in their fragile agriculture system. Imagine you were a farmer at the city-state of Uaxactun and you are at war with Tikal. Now, are you going to stay on your farm with no military protection? Of course not, you will move as fast as you can into the protection of the city walls. In the meantime your field becomes overgrown and no food can be produced. So we see cases of extreme food shortages that cannot be compensated for causing the demise of the Mayan culture.
