What is FLEA BEETLE?
FLEA BEETLE is a collection of computer programs that calculate and sum the
amount of heat that has occurred towards first and peak emergence of the flea beetle,
Aphthona nigriscutis Foudras; this beetle is an important biological
control agent of the noxious weed, leafy spurge (Euphorbia esula L.).
Many ranchers and farmers who suffer leafy spurge infestations try to contain
that weed by grazing with sheep. Further, A. nigriscutis adults (the
flea beetles) are being introduced into some pastures to kill
existing leafy spurge plants. In order to sustain and increase the numbers
of A. nigriscutis in spurge-infested pastures, the flea beetles
need to emerge unhindered by the sheep so they can feed on leafy spurge
foliage while they mate and lay eggs. FLEA BEETLE helps leafy spurge
managers determine the most likely date on which A. nigriscutis
adults will begin to emerge so the sheep can be removed before flea
beetle emergence.
