| plant-herbivore and plant-pollinator interactions of the developing perennial oilseed crop, silphium integrifolium. | sampling in kansas and north dakota documented the plant-herbivore and plant-pollinator interactions of the developing perennial oilseed crop, silphium integrifolium michx. the larva of the tortricid moth, eucosma giganteana (riley), was the most damaging floret- and seed-feeding pest in kansas, with infested heads producing ≈85% (2015) or ≈45% (2016) fewer seeds than apparently undamaged heads. necrosis of apical meristems caused stunting and delayed bloom in kansas; though the source of the ne ... | 2017 | 29029088 |
| impact of planting dates on a seed maggot, neotephritis finalis (diptera: tephritidae), and sunflower bud moth (lepidoptera: tortricidae) damage in cultivated sunflower. | neotephritisfinalis (loew) (diptera: tephritidae), and sunflower bud moth, suleima helianthana (riley) (lepidoptera: tortricidae) are major head-infesting insect pests of cultivated sunflower (helianthus annuus l.). planting date was evaluated as a cultural pest management strategy for control of n. finalis and s. helianthana in several production regions of north dakota during 2009 and 2010. results of the nine site-year study revealed that late planting date (early to mid-june) reduced damage ... | 2011 | 21882688 |
