Abstract

The hormetic influence on silkworm, Bombyx mori L. (Lepidoptera: Bombycidae) of the juvenile hormone mimic ω-formyl longifolene oxime propargyl ether (NL13) was assayed. Emulsions containing 2.5, 5.0 and 10.0 ppm of the compound were administered topically as a single dose, to two popular commercial silkworm hybrids, viz. KA × NB4D2 and PM × NB4D2, at 24,48, 72 and 96 h into the 5th instar, and economic characters of the larvae and resultant cocoons measured. A medium and absolute control were maintained in parallel. It was found that administration of 5 ppm of NL13 to 48-h-old 5th instars resulted in the maximum improvement in commercial traits. The possible role of exogenous JH-like compounds in eliciting this response in silkworm is discussed.

Résumé

L'influence hormonal du ω-formyl longifene oxime propargyl ether (NL13) imitant l'hormone juvénile a été testée sur le ver à soie, Bombyx mori L. (Lepidoptera: Bombycidae). Des émulsions contenant 2,5, 5,0 et 10,0 ppm du composé ont été administrées au 5ème stade larvaire, en une seule dose, à 24, 48, 72 et 96 h, à deux hybrides couramment commercialisés du ver à soie, viz KA × NB4D2 et PM × NB4D2 Les caractéristiques economiques des larves et des cocons ont été mesurées. Un témoin moyen et absolu ont été maintenus en parallèle. On a constaté que l'administration de 5 ppm de NL13 à des larves de 5eme stade âgées de 48 h a permis une amélioration maximale des caractéristiques commerciales. Le rôle possible des composés exogènes, homologues de l'hormone juvénile, provoquant cette réponse chez le ver à soie est discuté.
