Other claims from this paper (18)
- Association Blossom exposure duration changed the type of strawberry malformation.
- Intervention effect Exposure at anthesis for 48 hours was most likely to cause apical seediness.
- Association Nonviable achenes per fruit increased with longer feeding duration.
- Intervention effect Prebloom feeding caused blossom death.
- Intervention effect Feeding later in fruit development caused little damage.
- Observation In early fruit development, bugs fed on achenes.
- Observation On more developed fruit, bug feeding moved to receptacle tissue.
- Mechanism Achene injury early in fruit development was identified as the most likely cause of apical seediness.
- Intervention effect Later feeding caused local cell damage and receptacle indentations.
- Observation The twenty cultivars showed a wide range of tarnished bug injury.
- Observation 'Honeoye', 'Sparkle', 'Veestar' and 'Canoga' had significantly less injury than other cultivars.
- Observation 'Mic Mac', 'Scott', 'Blomidon' and 'Redchief' were most susceptible.
- Association Cultivars with less injury tended to have higher marketable yields.
- Association More susceptible cultivars harbored more nymphs.
- Observation Cultivar differences were greatest without insecticide.
- Observation 'Honeoye' and 'Sparkle' had the least apical seediness, followed by 'Redchief', 'Guardian' and 'Kent'.
- Observation 'Mic Mac' consistently had the most injury.
- Intervention effect Reducing insecticide applications did not increase apical seediness in low susceptibility cultivars.
