Impact of feeding by Lygus hesperus (Heteroptera: Miridae) on red clover grown for seed

Lygus hesperus Knight reduced seed set an average of 20% when five adult bugs fed 2 d on culms of red clover, Trifolium pratense L., in different stages of floral development. The dominant form of damage was shriveled seed pods approximately twice the size of reproductive parts of unpollinated flore...

Zusammenfassung:	Lygus hesperus Knight reduced seed set an average of 20% when five adult bugs fed 2 d on culms of red clover, Trifolium pratense L., in different stages of floral development. The dominant form of damage was shriveled seed pods approximately twice the size of reproductive parts of unpollinated florets. Bugs also produced shriveled seeds by feeding directly on seeds when the endosperm had a watery consistency.
