Life Cycle:

Srawberry bud nematode populations increased in the spring, precipitiously decreased during warm and dry summer and then rapidly recovered to the highest level in autumn. They were maintained in low abundance throughout a cold winter. No nematodes were detected in the internodes of stolons during the reproductive season of the plants.

Nematodes were disseminated in eady in the apical buds of runners still in the mother plants. During the seasons unfavourable for the reproduction and maintenance, the 4th stage juveniles and young females were survival stages, including survival of freezing contitions in dried buds (Kondo and Ishabashi, 1977).

Damage:

Symptoms of damage to strawberry plants caused by N. acris are the spiralling of young petioles, the crimping of young leaves, and plant dwarfing.. As a result fewer inflorescence, the infected plants have more vegetative runners than healthy plants (Kondo and Ishabashi, 1977; Nishizawa and Iyatomi, 1955).
