Aphrophora salicina

Distribution in Belgium

A. salicina was not found to be very widespread in the country ( Fig. 11 ). We caught it only in 6 sites out of 36, always on Salix spp. (table 4).

Adult phenology

Adults were found from June to October ( Fig. 12 ). We caught A. salicina in higher numbers in July and August.

Oviposition, egg winter diapause and voltinism

Oviposition was observed in slits at the tip of Salix shoots. In this univoltine species, the eggs overwinter and need a winter period to lift diapause.

Immature development under outdoor conditions

It took place between early April and early June ( Fig. 13 ). There are five instars, with spittle protection. The cephalic capsule width was 0.52,0 mm according to nymphal instar. Immature development lasted 63–76 days. The adults appeared between June 6 and 19.
