Abstract

The effects of providing (a) an artificial honeydew consisting of yeast autolysate, sugar and water in the ratio 4∶7∶10 live prey (eggs ofEphestia kuehniella), and (b) water and life prey, on larval development and survival in the green lacewingChrysoperla carnea were examined. Compared with larvae provided with eggs and water, those given eggs and artificial honeydew were more likely to complete their development and did so significantly more rapidly.

Résumé

L'effet, sur le développement larvaire deChrysoperla carnea, d'un mélange nutritif composé de miellat artificiel (autolysat de levure, sucre et eau dans les proportions 4∶7∶10) et de proies vivantes (œufs d'Ephestia kuehniella) a été étudié. En comparison des larves nourries d'œufs et d'eau, celles nourries d'œufs et de miellat artificiel arrivent plus sûrement au terme de leur développement et dans un temps significativement plus court.
