Differences in Oviposition of the Smaller Brown Planthopper, Laodephax striatellus, in Response to Various Amino Acid Solutions (Hemiptera : Delphacidae)

Abstract

The smaller brown planthopper, Laodelphax striatellus, exhibited egg deposition into a 5% sucrose solution through a Parafilm membrane, however, when a mixture of amino acids was added to the 5% sucrose solution, no eggs were laid. Among 23 individually tested amino acids, arginine, glutamic acid, tyrosine, and valine showed an inhibitory effect upon oviposition, whereas the influence of cystine was stimulative.
