叶盘选择和产卵生物测定被用来检验幼虫在戈尔登圆锥幼虫乳汁中的经历对后续行为的影响。这种乳胶可以阻止幼稚的卷心菜环纹夜蛾幼虫和蛾的取食和产卵，而以前没有接触过这种物质。与幼稚的昆虫相比，以高登乳胶(1000ppm)喂养的“有经验的”昆虫表现出较少的摄食威慑。经验丰富的雌蛾实际上更喜欢在经过处理的叶子上产卵，而不是在对照叶片上产卵。没有观察到有经验的父母将行为偏好转移给他们的后代。我们的结果表明，蛾可能从幼虫的取食经历中获得产卵偏好，正如霍普金斯的寄主选择原则(HHSP)所描述的那样，或通过化学遗产。
Leaf disc choice and oviposition bioassays were used to examine the effects of larval experience with a Hoodia gordonii latex on subsequent behaviors. The latex deterred feeding and oviposition by "naive" cabbage looper (Trichoplusia ni, Noctuidae) larvae and moths with no previous exposure to the material. "Experienced" insects, reared on a diet with the H. gordonii latex (1000 ppm), exhibited lesser feeding deterrence relative to naive insects. Experienced female moths actually preferred to lay eggs on treated rather than control leaves. There was no observed transfer of behavioral preferences from experienced parents to their offspring. Our results suggest that moths may be acquiring oviposition preferences from larval feeding experience as described by Hopkins' host selection principal (HHSP) or through chemical legacy.
