Top. A horizontal asymptote is a y-value which a function approaches. The asymptote is parallel to x axis, so is of the form y = a, for all real values of a. Thus if f(x) = y is a function, then y = a, becomes undefined for the function, then the line y = a, is called the asymptote for the function y = f(x).
The African armyworm (Spodoptera exempta) also called okalombo, kommandowurm, or nutgrass armyworm, is an African moth. It is a very deleterious pest, capable of destroying entire crops in a matter of weeks.
Wireworm (Click Beetle) These inch long, hard segmented-shell yellow, gray or reddish-brown worms are the larvae of beetles, normally voracious feeders of vegetable crops, eating the interior tissue of seeds and roots.
