To date there are no effective commercial biological agents available to control this grub. The most common parasite is a type of digger wasp, Scolia dubia Say. This beneficial wasp enters the grub tunnel, stings the grub, then lays an egg on the paralyzed grub. The resulting larva feeds in the grub, eventually killing it. In the mid-Atlantic outbreaks during the 1980s, several golf course superintendents noticed an increasing number of digger wasps flying around the course about the time populations subsided Do People Really Have Tiny download for free Do People Really Have Tiny Insects.

What this means is, the alleles that form the next generation's gene pool are a sample of the alleles from the current generation. When sampled from a population, the frequency of alleles differs slightly due to chance alone. Alleles can increase or decrease in frequency due to drift. The average expected change in allele frequency is zero, since increasing or decreasing in frequency is equally probable , cited: Rainforest Food Chains (InfoSearch: Food Chains) warholprints.com.
