AbstractThe experiments described have given the following conclusions: (I) A chemical signal (pheromone) emitted by the oviparous female has an attractive effect upon the males. This signal is not emitted by the virginogeniae. (2) The signal is emitted by organs situated on the hind tibiae of the oviparous female and perceived by organs on the male ...

Aphids are small insects which feed by inserting their very fine mouthparts (stylets) into plant tissue, where they feed on cell sap (Fig. 1 A + B). As an aphid inserts its stylets into plant tissue it secretes a stylet sheath around the stylets (Fig. 2 A + B).
