Abstract:
... A laboratory bioassay was developed for testing oviposition preference of southern green stink bug, Nezara viridula (L.) (Heteroptera: Pentatomidae), toward chemicals extracted from soybean, Glycine max (L.) Merrill, pods and leaves. In this bioassay, an artificial substrate (cheesecloth) was stretched over a wooden ring (embroidery hoops), treated with plant extracts or chromatographic fractions, ...

Inoculative releases of parasitized female thrips were made seven times into the caged impatiens preinfested with adult thrips. Two rates were used, one or two parasitized thrips per release date, and impacts on thrips p ...
