Effect of Three Chemosterilants on the Pea Aphid Fed on an Artificial Diet1

Abstract
Nymphs of the pea aphid, Acyrthosiphon pisum (Harris), were fed on a chemical diet containing apholate, tepa, or metepa, and progeny were counted after nymphs became adults and began reproducing. Apholate inhibited reproduction at dosages from 0.1-0.005%, but caused no mortality to feeding nymphs at any dosages from 0.1-0.001%. Tepa inhibited reproduction at dosages of 0.1-0.0025%, but caused some mortality to feeding nymphs at dosages higher than 0.025%. Metepa could not be clearly demonstrated as a chemosterilant because it was too toxic to feeding nymphs.
