We studied for two years (1996 and 1997) the communities of phytophagous pests and predator-parasitoids living on 41 varieties/selections of strawberry (Fragaria x ananassa). The results show significant differences in the arthropod communities: populations of aphids and two-spotted spider mite are scarce or even absent on some cultivars. Statistical analyses support the variability of pest colonization patterns and of plant responses to attack, probably related to changes in biological cycles and different environmental conditions. The different responses of strawberry varieties/selections to pest attack could represent a basis to develop new cultivars for sustainable agriculture.

Abstract
We studied for two years (1996 and 1997) the communities of phytophagous pests and predator-parasitoids living on 41 varieties/selections of strawberry (Fragaria x ananassa). The results show significant differences in the arthropod communities: populations of aphids and two-spotted spider mite are scarce or even absent on some cultivars. Statistical analyses support the variability of pest colonization patterns and of plant responses to attack, probably related to changes in biological cycles and different environmental conditions. The different responses of strawberry varieties/selections to pest attack could represent a basis to develop new cultivars for sustainable agriculture.I documenti in SFERA sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
