Abstract

Quercetin, a growth-inhibiting compound that is produced by many plants, was incorporated into an artificial diet and fed to Heliothis virescens (Boddie) larvae. Eggs were collected from females that had developed on this diet and from females that had developed on unadulterated artificial diet. Neonates from these eggs were placed on diets containing quercetin or other commonly occurring plant compounds (rutin, gossypol, gramine). Offspring from parents that had developed on quercetin-containing diet grew more slowly on diets containing quercetin, rutin, or gossypol, than did larvae from parents reared on unadulterated diet. Larvae from both types of parents grew at the same rate when reared on gramine-containing diet. Maternal, but not paternal, diet led to decreased growth of offspring on quercetin-containing diet. When reared on quercetin- and rutin-containing diets, offspring from parents that had developed on tobacco or soybean grew more slowly than larvae from parents reared on unadulterated diet.

Résumé

On a incorporé de la quercétine, une substance inhibitrice de la croissance et produite par diverses plantes, dans le régime artificiel donné en nourriture à des larves d'Heliothis virescens (Boddie). On a collecté les oeufs provenant de femelles élevées sur ce régime et ceux de femelles témoins élevées sur régime normal. Les jeunes larves écloses de ces oeufs ont été placées sur des régimes contenant de la quercétine ou d'autres substances végétales communes : ratine, gossypol, gramine. Les progénitures de parents élevés sur régime traité à la quercétine, à la rutine ou au gossypol se sont développées plus lentement que celles issues de parents élevés sur régime non altéré. Le taux de développement de larves issues de parents des deux types était le même dans le cas de régime traité à la gramine. Par contre, c'est l'élevage de la mère sur régime altéré, et non pas celui du père, qui a réduit la croissance des progénitures dans le cas d'ajout de quercétine au régime. Lorsqu'élevées sur régime avec quercétine ou rutine, des progénitures de parents élevés sur tabac ou fève soya ont montré un développement plus lent que celles issues de parents élevés sur régime non altéré.
