Ticks then thrive on the rodents, which are poor groomers.
Studies suggest that larval ticks have a 50% chance of surviving when they feed on mice, but only a 3.5% chance on opossums.

they’re food for fish and other insect predators and birds. They pollinate plants.

Correction: Only the female has the need for the iron from our blood for her offspring.

Dina Fonseca, a professor of entomology at Rutgers University, is that the biting midge is the only known pollinator of cacao.

The Cockroach of Mosquitoes

Experts working to halt the spread of the Zika, dengue and chikungunya viruses face a stubborn foe in the main mosquito that transmits them, and some of the many methods under consideration for fighting them are stirring controversy.

The Aedes aegypti mosquito primarily responsible for spreading these diseases has been called “the cockroach of mosquitoes.” It thrives around people, particularly in the densely packed neighborhoods that are common in the tropics. It bites during the day and hides at night in dark corners,…

Vibrio vulnificus

Vibrio vulnificus

from the “Bad Bug Book,” Center for Safety
and Applied Nutrition, US FDA (Food and Drug Administration) at

There are 2 points to be emphasized:

  • that vibrios are normal flora in warm saltwater (not indicative of any sewage contamination) and that
  • most of the life-threatening illnesses occur in individuals with
    underlying medical illnesses, including immunocompromised states, chronic liver disease, and diabetes. So-called normal individuals often just get gastroenteritis. The range of disease due to V. vulnificus can involve more northern geographical areas if the area is affected by a substantial heat wave.
